Clinical predictors of persistent temporomandibular disorder in people with first-onset temporomandibular disorder: A prospective case-control study

BackgroundWhen patients first develop a painful temporomandibular disorder (TMD) and seek care, 1 priority for clinicians is to assess prognosis. The authors aimed to develop a predictive model by using biopsychosocial measures from the Diagnostic Criteria for Temporomandibular Disorders (DC-TMD) to predict risk of developing TMD symptom persistence.MethodsAt baseline, trained examiners identified 260 participants with first-onset TMD classified by using DC-TMD–compliant protocols. After follow-up at least 6 months later, 72 (49%) had examiner-classified TMD (persistent cases), and 75 (51%) no longer had examiner-classified TMD (transient cases). For multivariable logistic regression analysis, the authors used blocks of variables selected using minimum redundancy maximum relevance to construct a model to predict the odds of TMD persistence.ResultsAt onset, persistent cases had multiple worse TMD clinical measures and, among Axis II measures, only greater baseline pain intensity (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.04 to 2.2; P = .030) and more physical symptoms (OR, 1.8; 95% CI, 1.2 to 2.9; P = .004) than did transient cases. A multivariable model using TMD clinical measures showed greater discriminative capacity (area under the receiver operating characteristic curve, 0.74; 95% CI, 0.73 to 0.75) than did a model involving psychosocial measures (area under the receiver operating characteristic curve, 0.63; 95% CI, 0.62 to 0.64).ConclusionsClinical measures that clinicians can assess readily when TMD first develops are useful in predicting the risk of developing persistent TMD. Psychosocial measures are important predictors of onset but do not add meaningfully to the predictive capacity of clinical measures.Practical ImplicationsWhen TMD first develops, clinicians usefully can identify patients at higher risk of developing persistence by using clinical measures that they logically also could use in treatment planning and for monitoring outcomes of intervention.     

Occlusal splints-types and effectiveness in temporomandibular disorder management

BackgroundOcclusal splints are routinely used in dental offices to diagnose and treat abnormalities of the masticatory system. There are different occlusal splints, each of which can address various conditions. They may treat individuals with temporomandibular disorders (TMDs) and bruxism or be used for occlusal stabilization and dentition wear reduction.MethodsThe literature in the National Library of Medicine's Medline Database was reviewed using the Mesh terms 'occlusal splints' AND 'Temporomandibular Disorders.ConclusionOcclusal splints can treat a wide variety of TMDs. They can treat bruxism, headaches, postural imbalances related to TMDs, and decreased vertical dimension of occlusion (VDO). However, there is no clear evidence that occlusal splints are superior to physiotherapy in treating TMDs. In the long-term follow-up, they were equally effective as other therapies.     

Oral health–related quality of life of patients with acute and chronic temporomandibular disorder diagnostic subtypes

BackgroundStudies have indicated the negative effects of temporomandibular disorders (TMDs) on oral health–related quality of life (OHRQoL). The authors investigated the OHRQoL of patients with acute and chronic TMD subtypes.MethodsThe authors recruited a total of 830 patients. They derived TMD diagnoses using the Diagnostic Criteria for TMDs protocol involving symptom history, physical examination, and diagnostic imaging as indicated. The authors categorized patients into acute (≤ 3 months) or chronic (> 3 months) pain-related TMD (PT), nonpainful intra-articular TMD (IT), and combined TMD (CT) groups. They also gathered sociodemographic information and assessed OHRQoL with the Oral Health Impact Profile (OHIP)-TMDs. The authors evaluated data using 2-way analysis of variance and Bonferroni test and multiple regression analysis.ResultsPatients in the chronic PT and CT subgroups had significantly higher mean global OHIP scores than their acute counterparts. The authors observed significant acute-chronic differences in OHIP-TMDs domain scores in 5 and 2 domains for the PT and CT groups, respectively. Patients in the acute IT group had significantly higher functional limitation scores than those in the chronic IT group. The ranking of mean global scores, in descending order was CT, PT, and IT for acute TMDs and PT, CT, and IT for chronic TMDs, with significant differences observed among the 3 TMD subtypes (P < .001).ConclusionsBoth TMD chronicity and subtypes influenced OHRQoL. Painful TMDs (PT and CT) were associated with significantly poorer OHRQoL than nonpainful TMDs. TMD chronicity appeared to affect OHRQoL only for the painful TMD conditions. Future work on the impact of TMDs on OHRQoL should strive to stratify patients by TMD chronicity and subtypes.Practical ImplicationsTMD chronicity and subtypes influence the impact of TMDs on OHRQoL. Given that chronic painful TMDs impair quality of life, early biopsychosocial intervention of acute TMD pain is important for minimizing chronification and OHRQoL deterioration.     

Management of painful temporomandibular disorders: Methods and overview of The National Dental Practice-Based Research Network prospective cohort study

BackgroundPatients often seek consultation with dentists for temporomandibular disorders (TMDs). The objectives of this article were to describe the methods of a large prospective cohort study of painful TMD management, practitioners’ and patients’ characteristics, and practitioners’ initial treatment recommendations conducted by The National Dental Practice-Based Research Network (the “network”).MethodsParticipating dentists recruited into this study treated patients seeking treatment for painful TMDs. The authors developed self-report instruments based on well-accepted instruments. The authors collected demographics, biopsychosocial characteristics, TMD symptoms, diagnoses, treatments, treatment adherence, and painful TMDs and jaw function outcomes through 6 months.ResultsParticipating dentists were predominately White (76.8%) and male (62.2%), had a mean age of 52 years, and were general practitioners (73.5%) with 23.8% having completed an orofacial pain residency. Of the 1,901 patients with painful TMDs recruited, the predominant demographics were White (84.3%) and female (83.3%). Patients’ mean age was 44 years, 88.8% self-reported good to excellent health, and 85.9% had education beyond high school. Eighty-two percent had pain or stiffness of the jaw on awakening, and 40.3% had low-intensity pain. The most frequent diagnoses were myalgia (72.4%) and headache attributed to TMDs (51.0%). Self-care instruction (89.4%), intraoral appliances (75.4%), and medications (57.6%) were recommended frequently.ConclusionsThe characteristics of this TMD cohort include those typical of US patients with painful TMDs. Network practitioners typically managed TMDs using conservative treatments.Practical ImplicationsThis study provides credible data regarding painful TMDs and TMD management provided by network practitioners across the United States. Knowledge acquired of treatment recommendations and patient reports may support future research and improve dental school curricula.     

The prevalence of comorbid chronic pain conditions among patients with temporomandibular disorders: A systematic review

BackgroundThis systematic review was designed to evaluate the presence of comorbid conditions among patients with temporomandibular disorders (TMDs).Types of Studies ReviewedThe authors reviewed studies that reported the prevalence or incidence of chronic pain conditions or psychiatric disorders (anxiety, mood, personality disorders) among patients with any type of TMD. The authors calculated sample size–weighted prevalence estimates when data were reported in 2 or more studies for the same comorbid condition.ResultsA total of 9 prevalence studies and no incidence studies were eligible for review; 8 of the studies examined chronic pain comorbidities. Weighted estimates showed high prevalence of pain comorbidities across studies, including current chronic back pain (66%), myofascial syndrome (50%), chronic stomach pain (50%), chronic migraine headache (40%), irritable bowel syndrome (19%), and fibromyalgia (14%). A single study examined psychiatric disorders and found that current depression was the most prevalent disorder identified (17.5%).Conclusions and Practical ImplicationsThere is a high prevalence of comorbid chronic pain conditions among patients with TMDs, with more than 50% of patients reporting chronic back pain, myofascial syndrome, and chronic stomach pain. Psychiatric disorders among patients with different types of TMDs were studied less commonly in this pain population. Knowledge of the distribution of these and other comorbid disease conditions among patients with different types of TMDs can help dentists and other health care providers to identify personalized treatment strategies, including the coordination of care across medical specialties.     

Systematic review and meta-analysis on the effect of self-assembling peptide P11-4 on arrest,cavitation, and progression of initial caries lesions

BackgroundSimple noninvasive evidence-based interventions for caries are needed to overcome limitations in the restorative paradigm. The self-assembling peptide P₁₁-4 is a noninvasive intervention that regenerates enamel in initial caries lesions.Studies ReviewedThe authors conducted a systematic review and meta-analysis on the effectiveness of the P₁₁-4 products Curodont Repair (Credentis; now manufactured by vVARDIS) (CR) and Curodont Repair Fluoride Plus (Credentis; now manufactured by vVARDIS) on initial caries lesions. Primary outcomes were lesion progression after 24 months, caries arrest, and cavitation. Secondary outcomes were changes in merged International Caries Detection and Assessment System score categories, quantitative light-induced fluorescence (QLF; Inspektor Research System), esthetic appearance, and lesion size.ResultsSix clinical trials met the inclusion criteria. Results of this review represent 2 primary and 2 secondary outcomes. When compared with parallel groups, use of CR likely results in a large increase in caries arrest (relative risk [RR], 1.82 [95% CI, 1.32 to 2.50]; 45% attributable risk [95% CI, 24% to 60%]; number needed to treat [NNT], 2.8) and likely decreases lesion size by a mean (SD) of 32% (28%). The evidence also suggests that use of CR results in a large reduction in cavitation (RR, 0.32 [95% CI, 0.10 to 1.06]; NNT, 6.9) and is uncertain about lowering merged International Caries Detection and Assessment System score (RR, 3.68 [95% CI, 0.42 to 32.3]; NNT, 19). No studies used Curodont Repair Fluoride Plus. No studies reported adverse esthetic changes.Practical ImplicationsCR likely has clinically important effects on caries arrest and decreased lesion size. Two trials had nonmasked assessors, and all trials had elevated risks of bias. The authors recommend conducting longer trials. CR is a promising treatment for initial caries lesions. The protocol for this systematic review was registered a priori with PROSPERO (304794).     

Examining the association of medical-dental integration with closure of medical care gaps among the elderly population

BackgroundThe integration of medical and dental care in the dental setting offers a unique opportunity to close medical care gaps, such as providing immunizations and laboratory-based tests, compared with traditional nonintegrated settings.MethodsWe used a matched cohort study design among patients 65 years or older (n = 2,578) with an index dental visit to the Kaiser Permanente Northwest medical-dental integration (MDI) program from June 1, 2018, through December 31, 2019. MDI patients were matched 1:1 to non-MDI controls (n = 2,578) on 14 characteristics. The Kaiser Permanente Northwest MDI program focuses on closing 23 preventive (for example, flu vaccines) and disease management care gaps (for example, glycated hemoglobin testing) within the dental setting. The closure of all care gaps (yes versus no) was the outcome for the analysis. Multivariable logistic regression was used to evaluate the association between exposure to the MDI program and level of office integration (least, moderate, and most integration) with closure of care gaps. All data were obtained through Kaiser Permanente Northwest’s electronic health record.ResultsMDI patients had significantly higher odds (odds ratio [OR], 1.46, 95% confidence interval [CI], 1.29 to 1.65) of closing all medical care gaps than non-MDI patients. Greater MDI integration was associated with significantly higher odds of gap closure compared with non-MDI (least integration: OR, 1.18, 95% CI, 1.02 to 1.37; moderate integration: OR, 1.70, 95% CI, 1.36 to 2.12; most integration: OR, 2.08, 95% CI, 1.73 to 2.50).ConclusionsPatients receiving dental care in an MDI program had higher odds of closing medical care gaps compared with similar patients receiving dental care in a non-MDI program.Practical ImplicationsMDI is effective at facilitating delivery of preventive and disease management medical services.     

Tooth loss and uncontrolled diabetes among US adults

BackgroundThe objective of this study was to analyze the association between tooth loss and uncontrolled diabetes among US adults.MethodsThe authors used National Health and Nutrition Examination Survey data from 2011 through 2018. The sample included 16,635 participants 20 years and older who represent 187,596,215 people in the United States in a probability weighted sample. The authors used bivariate analysis and multiple regressions to analyze factors associated with edentulism and number of missing teeth.ResultsThe multiple logistic regression model significantly predicted edentulism using diabetes status (adjusted odds ratio controlled diabetes, 1.44 [95% CI, 1.12 to 1.86]; adjusted odds ratio uncontrolled diabetes, 2.26 [95% CI, 1.33 to 3.85]), missing annual dental visits, seeing a dentist only for treatment, family income below 200% of the federal poverty guideline, being female, being 65 years or older, tobacco smoking, and no college education. After controlling for the same covariates, multiple Poisson regression analysis showed that dentate adults with controlled and uncontrolled diabetes had higher relative risk of tooth loss than those without diabetes (adjusted risk ratio controlled diabetes, 1.52 [95% CI, 1.35 to 1.71]; adjusted risk ratio uncontrolled diabetes, 1.57 [95% CI, 1.35 to 1.83]).ConclusionsUS adults with uncontrolled (glycated hemoglobin ≥ 9%) and controlled diabetes (glycated hemoglobin < 9%) were more likely to be edentulous and experience tooth loss than adults without diabetes.Practical ImplicationsUS health policy officials should adopt benefits policies to provide regular dental examinations to people who have diabetes, have low income (< 200% of the federal poverty guideline), or are 65 years or older to reduce tooth loss and improve their quality of life. Dentists should work with physicians to help patients control glycemic levels.     

Implementation of repairs in dental practice: Randomized behavior simulation trial

BackgroundDespite increasing evidence, dentists have not widely adopted repairs. The authors aimed to develop and test potential interventions targeting dentists’ behavior.MethodsProblem-centered interviews were performed. Emerging themes were linked to the Behavior Change Wheel to develop potential interventions. The efficacy of 2 interventions was then tested in a postally delivered behavioral change simulation trial among German dentists (n = 1,472 per intervention). Dentists’ stated repair behavior regarding 2 case vignettes was assessed. Statistical analysis was performed using McNemar test, Fisher exact test, and a generalized estimating equation model (P < .05).ResultsTwo interventions (guideline, treatment fee item) were developed on the basis of identified barriers. A total of 504 dentists participated in the trial (17.1% response rate). Both interventions significantly changed dentists’ behavior toward repairs of composite and amalgam restorations, respectively (guideline: difference [Δ] = +7.8% and Δ = +17.6%, treatment fee item: Δ = +6.4% and Δ = +31.5%; adjusted P < .001). Dentists were more likely to consider repairs if they already performed repairs frequently (odds ratio [OR], 1.23; 95% CI, 1.14 to 1.34) or sometimes (OR, 1.08; 95% CI, 1.01 to 1.16), if they regarded repairs as highly successful (OR, 1.24; 95% CI, 1.04 to 1.48), if their patients preferred repairs over total replacements (OR, 1.12; 95% CI, 1.03 to 1.23), for partially defective composite restorations (OR, 1.46; 95% CI, 1.39 to 1.53), and after receiving 1 of the 2 behavioral interventions (OR, 1.15; 95% CI, 1.13 to 1.19).ConclusionsSystematically developed interventions targeting dentists’ repair behaviors are likely efficacious to promote repairs.Practical ImplicationsMost partially defective restorations are replaced completely. Effective implementation strategies are required to change dentists’ behavior.This trial was registered at https://www.clinicaltrials.gov. The registration number is NCT03279874 for the qualitative phase and NCT05335616 for the quantitative phase.     

The association between food insecurity,diet quality,and untreated caries among US children

BackgroundThe aim of this study was to examine the association between food insecurity and untreated caries among US children and the potential role of diet quality as a mediator in this relationship.MethodsThe authors analyzed data for 4,822 children aged 5 through 17 years from the National Health and Nutrition Examination Survey cycles from 2011 through 2014. The authors measured food security as household-level food security status (full, marginal, low, very low) and overall food security status (full food secure, food insecure). They measured diet quality using the Healthy Eating Index. The primary outcome measure was untreated caries (none, ≥ 1). The authors used multiple logistic regression analysis to evaluate the relationships among food insecurity, diet quality, and untreated caries. They conducted mediation analysis using the Baron and Kenny approach.ResultsFood-insecure children were more likely to have untreated caries compared with their fully food-secure counterparts, after controlling for confounding variables (odds ratio [OR], 1.38; 95% [CI, 1.11 to 1.72). Specifically, children from marginal and very low food-secure households had significantly higher odds of untreated caries (OR, 1.48; 95% CI, 1.10 to 2.01) compared with children from fully food-secure households (OR, 1.59; 95% CI, 1.12 to 2.26). Diet quality was not significantly associated with untreated caries.ConclusionsFood insecurity was negatively associated with untreated caries among US children. Diet quality was not associated with untreated caries.Practical ImplicationsSocial factors such as food insecurity should be taken into consideration when dental clinicians perform caries risk assessment because caries risk is shown to be associated with overall health and dental health.     

The association of apical periodontitis and type 2 diabetes mellitus: A large hospital network cross-sectional case-controlled study

BackgroundThe relationship of apical periodontitis (AP) and type 2 diabetes mellitus (T2DM) is poorly studied in large populations. The aims of this study were to determine if there is an independent association between AP and T2DM in a large hospital network after controlling for confounding variables, as well as to determine if glycated hemoglobin levels were independently associated with AP.MethodsAn initial search of the Carolina Data Warehouse for Health yielded 5,995,011 patients, of whom 7,749 were diagnosed with AP in 2015 through 2018. Patients’ demographics, T2DM status, HbA_1c, periodontal disease, oral cellulitis, hypertension, atherosclerosis, kidney disease, smoking, body mass index, the use of metformin or statins, and hospital inpatient status were collected from their most recent visit. A control group of 7,749 patients without AP were sampled and matched according to the age, race, and sex of each patient with AP. Multiple logistic regression was used to determine the association between T2DM and AP, as well as between HbA_1c and AP after controlling for the effects of the aforementioned confounding variables, using a matched cohort design.ResultsT2DM was independently associated with significantly greater prevalence of AP (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.73 to 2.43). The use of metformin (OR, 0.82; 95% CI, 0.69 to 0.98) or statins (OR, 0.70; 95% CI, 0.62 to 0.78) was independently associated with significantly lower prevalence of AP. HbA_1c greater than 8.0 (OR, 2.46; 95% CI, 1.83 to 3.35) was significantly associated with greater prevalence of AP.ConclusionsT2DM and poorly controlled glycemia were significantly associated with AP. Metformin and statin use were associated with lower prevalence of AP.Practical ImplicationsThis study provides evidence linking T2DM and the level of glycemia to the increased prevalence of AP. Statins and metformin use may be protective in this relationship.     

The Healthy Eating Index and coronal dental caries in US adults: National Health and Nutrition Examination Survey 2011-2014

BackgroundThe purpose of this cross-sectional study was to determine if Healthy Eating Index (HEI-2015) scores are associated with coronal caries and the odds of untreated coronal caries in adults 20 years and older.MethodsData on decayed, missing, and filled teeth (DMFT), untreated coronal caries, and HEI-2015 scores were obtained from 7,751 adults who completed a dental examination and two 24-hour dietary recalls in National Health and Nutrition Examination Survey cycles 2011-2012 and 2013-2014. HEI-2015 scores were categorized into quintiles, with HEI-2015 quintile 1 scores indicating the least compliance with 2015-2020 Dietary Guidelines for Americans. The authors used multivariable linear regression to assess associations of HEI-2015 with DMFT and logistic regression for associations with untreated coronal caries. All regression models were controlled for age, sex, race or ethnicity, current cigarette use, family income to poverty threshold ratio, last dental visit, education, and whether participants were ever told they had a heart attack.ResultsRelative to HEI-2015 quintile 1, the adjusted odds of any untreated coronal caries were quintile 5 (odds ratio [OR], 0.61; 95% confidence interval [CI], 0.46 to 0.80), quintile 4 (OR, 0.66; 95% CI, 0.53 to 0.84), quintile 3 (OR, 0.76; 95% CI, 0.56 to 1.04), and quintile 2 (OR, 0.93; 95% CI, 0.66 to 1.31). Participants who met the recommendations for the total fruits, whole fruits, greens and beans, and added sugars components of the HEI-2015 score were less likely to have untreated coronal caries than those who did not meet the recommendations. Overall, mean coronal DMFT also decreased as HEI-2015 scores increased, but trends were not consistent in all racial or ethnic groups.Conclusions and Practical ImplicationsGreater compliance with the Dietary Guidelines for Americans is associated with lower prevalence and the odds of untreated caries in adults. Dietary counseling for caries prevention by dental professionals should incorporate comprehensive dietary guidelines that are consistent with those intended for enhancing overall health and reducing the risk of developing common systemic diseases.     

Clinical and pathologic factors associated with the relapse of fibrous gingival hyperplasia

BackgroundThe association between clinicopathologic characteristics and the relapse of fibrous gingival hyperplasia is unknown.MethodsThe records of 211 consecutive patients with a clinicopathologic diagnosis of fibrous gingival hyperplasia were retrieved. Patients who experienced relapse after surgical excision of the lesion were considered case patients (n = 30). All control patients were informed that there was no recurrence (n = 181). Logistic regression was used to evaluate the associations among different characteristics and the recurrence. Stratified analyses on sex was applied to identify the different associations.ResultsBinary logistic regression showed that patients with ulcer (odds ratio [OR], 3.23; 95% CI, 1.18 to 8.83) or mechanical stimulation (OR, 2.42; 95% CI, 1.03 to 5.68) had a higher risk of experiencing recurrence. Stratified analysis of sex identified significant association in females (ulcer: OR, 4.04; 95% CI, 1.14 to 14.34; mechanical stimulation: OR, 3.30; 95% CI, 1.15 to 9.42). No significant difference was observed in males (ulcer: OR, 2.44; 95% CI, 0.40 to 15.06; mechanical stimulation: OR, 1.62; 95% CI, 0.28 to 9.40). Male patients with larger epulides had fewer recurrence (OR, 0.13; 95% CI, 0.02 to 0.74). There was no significant difference in pathologic calcification between case and control patients (P > .05).ConclusionsPatients with ulcer and mechanical stimulation may have a high risk of experiencing recurrent epulis.Practical ImplicationsMore attention should be paid to patients with ulcer and mechanical stimulation. Apart from complete surgical removal, it is important to remove local stimulation to prevent recurrence of these lesions.     

Chairside risk assessment for first-onset temporomandibular disorders: Result from the Orofacial Pain: Prospective Evaluation and Risk Assessment data set

BackgroundTemporomandibular disorders (TMD) risk assessment is difficult in general dentistry owing to the complexity of multifactorial risk contributions and the lack of standardized education. The authors explored a health history–based chairside risk assessment.MethodsSecondary data analysis was performed on the Orofacial Pain: Prospective Evaluation and Risk Assessment data set. Potential demographic, systemic, and local risk contributors were conceptualized into 10 risk categories. Multivariate Cox proportional hazards modeling with backward selection was applied. Variables with P values < .05 were kept in each successive model.ResultsThe analysis included data from 2,737 participants. The final model indicated that people with any psychological conditions, pain disorders, sleep disorders, or orofacial symptoms were at elevated risks of developing first-onset TMD. Results of post hoc analysis showed the coexistence of conditions from multiple body systems conferred greater risk of developing TMD.ConclusionsCoexisting conditions and symptoms from multiple body systems substantially increase the risk of developing TMD pain. Therefore, multisystem risk assessment and interprofessional collaborations are important for the prevention of TMD.Practical ImplicationsDentists should include psychological conditions, pain disorders, sleep disorders, and orofacial symptoms when assessing patients’ risk of developing TMD pain.     

Oromandibular dystonia and temporomandibular disorders

BackgroundThe aim of this study was to characterize clinical features of patients with oromandibular dystonia (OMD) who had temporomandibular disorder (TMD) symptoms.MethodsA retrospective chart review of patients seeking treatment at a tertiary-level orofacial pain clinic from January 2015 through December 2020 was undertaken. The inclusionary criteria consisted of a diagnosis of OMD (International Classification of Diseases, Revision 10 code G24.4), which had been confirmed by a neurologist.ResultsEleven patients met the inclusion criteria. Focal dystonia and jaw deviation OMD were the most frequent diagnoses. A dental procedure was a triggering or aggravating factor in 36.4% of patients. All but 2 patients had a sensory trick, or tactile stimulus to a particular body part, and approximately one-half of the patients used an oral appliance as a sensory trick device. All but 1 patient had received a diagnosis of TMD, with myofascial pain of the masticatory muscles being the most prevalent diagnosis. Four patients had received a recommendation for orthodontic treatment. About one-half of the patients had undergone 1 or more invasive dental or maxillofacial surgical interventions to address their dystonia. Anxiety was the most common psychological comorbidity.ConclusionsBecause patients with OMD commonly experience TMD symptoms, they can receive a misdiagnosis of TMD while the OMD is overlooked.Practical ImplicationsOwing to concomitant TMD symptoms, patients most often seek dental consultations and undergo treatments such as orthodontic interventions and temporomandibular joint surgeries. A dentist’s competency in recognizing these patients can prevent unnecessary procedures and facilitate appropriate patient care.     

Zirconia-ceramic versus metal-ceramic posterior multiunit tooth-supported fixed dental prostheses: A systematic review and meta-analysis of randomized controlled trials

BackgroundThe authors aimed to compare the survival and complication rates of zirconia-ceramic (ZC) versus metal-ceramic (MC) restorative material in multiunit tooth-supported posterior fixed dental prostheses (FDP).Types of Studies ReviewedThe authors conducted a systematic search of randomized controlled trials (RCTs), with no time or language restrictions, up to May 2019 using the MEDLINE (PubMed), Scopus, Web of Science, and Cochrane Central Register of Controlled Trials databases, followed by a manual search.ResultsThe authors included 7 RCTs in the review and 5 RCTs in the meta-analysis. All studies had a low risk of bias. The authors included 330 participants (177 ZC and 173 MC tooth-supported FDP) in the meta-analysis, which revealed a medium-term survival rate of 95.4% (95% confidence interval [CI], 90.5% to 99.1%) for ZC FDP compared with 96.9% (95% CI, 94.3% to 99.4%) for MC FDP, with no significant differences (P = .364). The biological or technical complications did not show statistically significant differences, except in the global ceramic veneering chipping analysis (P = .023; risk difference [RD], 22.3%; 95% CI, 3.0% to 41.6%) and their subanalysis: minor chipping or chipping that can be solved with polishing (P = .044; RD, 19.5%; 95% CI, 0.5% to 38.4%), and major chipping or chipping that needs repair in the laboratory (P = .023; RD, 6.0%; 95% CI, 0.8% to 11.3%).Conclusions and Practical ImplicationsPosterior multiunit ZC restorations are considered a predictable treatment in the medium term, although they are slightly more susceptible to chipping of the veneering ceramic than MC restorations.     

Efficacy of oscillating rotating versus side-to-side powered toothbrushes on plaque and gingival index reduction: A systematic review

BackgroundThe authors conducted a systematic review to assess the efficacy of oscillating rotating (OR) versus side-to-side (SS) powered toothbrushes on plaque and gingival index reduction.MethodsThe authors searched 3 electronic databases and the gray literature for randomized clinical trials in which investigators compared OR with SS powered toothbrushes. Two authors independently screened the studies, performed data abstraction, and assessed the risk of bias. The authors used random-effects model meta-analyses to pool results across trials and the Grading of Recommendations Assessment, Development and Evaluation approach to rate the certainty of evidence.ResultsThis systematic review included 24 trials in which researchers enrolled a total of 2,998 patients. There was moderate-certainty evidence that SS toothbrushes may result in little to no difference in plaque index reduction from baseline to 4 weeks compared with OR toothbrushes (standardized mean difference, 0.02; 95% confidence interval, –0.46 to 0.42). There was moderate-certainty evidence that SS toothbrushes may result in little to no difference in gingival index reduction from baseline to 4 weeks compared with OR toothbrushes (standardized mean difference, 0.13; 95% confidence interval, –0.47 to 0.22). There was moderate-quality evidence suggesting little to no difference in adverse events.ConclusionsThe evidence does not suggest the superiority of either OR or SS toothbrushes for plaque or gingival index reduction.Practical ImplicationsClinicians and patients considering the use of either of these toothbrushes are unlikely to observe more benefits with one type versus the other.     

Oral disorders associated with the experience of verbal bullying among Brazilian school-aged children: A case-control study

BackgroundDental features have been considered a potential target of verbal bullying (VB) among school-aged children. The authors conducted a study to investigate the association between the presence of oral disorders and the occurrence of VB among 8- through 10-year-old school-aged children.MethodsThe study included 445 school-aged children 8 through 10 years old. VB was verified by a specific validated question from the Child Perceptions Questionnaire 8-10 index. Oral disorders such as untreated caries, fluorosis, clinical consequences of untreated caries, and malocclusion were evaluated. The Pearson χ² test and bivariate and multivariate conditional logistic regression analyses were used for statistical analysis.ResultsA total of 390 school-aged children completed the study. The results of the multivariate logistic regression model showed that a severe malocclusion (odds ratio [OR], 2.29; 95% confidence interval [CI], 1.03 to 5.10), a greater maxillary misalignment (OR, 2.23; 95% CI, 1.05 to 4.73), and the presence of a tooth with pulp exposure (OR, 2.93; 95% CI, 1.58 to 5.45) were significantly associated with the occurrence of VB.ConclusionChildren aged 8 through 10 years with a severe malocclusion, larger maxillary misalignment, or the presence of pulp exposure had increased odds of experiencing VB compared with children without those oral health conditions.Practical ImplicationsOnce oral disorders involved in VB are identified, appropriate approaches should be used to address this issue. With this course of action, oral health care professionals may use the treatment and preventive care to eliminate potential factors for peer aggression.     

Analgesics for the management of acute dental pain in the pediatric population: A systematic review and meta-analysis

BackgroundThe authors assessed the clinical effectiveness of analgesics to manage acute pain after dental extractions and pain associated with irreversible pulpitis in children.Types of Studies ReviewedThe authors searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and US Clinical Trials registry from inception through November 2020. They included randomized controlled trials comparing any pharmacologic interventions with each other and a placebo in pediatric participants undergoing dental extractions or experiencing irreversible pulpitis. After duplicate screening and data abstraction, the authors conducted random-effects meta-analyses. They assessed risk of bias using the Cochrane Risk of Bias 2.0 tool and certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach.ResultsThe authors included 6 randomized controlled trials reporting 8 comparisons. Ibuprofen may reduce pain intensity compared with acetaminophen (mean difference [MD], 0.27 points; 95% CI, −0.13 to 0.68; low certainty) and a placebo (MD, −0.19 points; 95% CI, −0.58 to 0.21; low certainty). Acetaminophen may reduce pain intensity compared with a placebo (MD, −0.13 points; 95% CI, −0.52 to 0.26; low certainty). Acetaminophen and ibuprofen combined probably reduce pain intensity compared with acetaminophen alone (MD, −0.75 points; 95% CI, −1.22 to −0.27; moderate certainty) and ibuprofen alone (MD, −0.01 points; 95% CI, −0.53 to 0.51; moderate certainty). There was very low certainty evidence regarding adverse effects.Practical ImplicationsSeveral pharmacologic interventions alone or in combination may provide a beneficial effect when managing acute dental pain in children. There is a paucity of evidence regarding the use of analgesics to manage irreversible pulpitis.     

Impact of disability diagnosis on dental care use for adults in the United States: Status matters

BackgroundApproximately 25% of adults in the United States have a disability that limits function and independence. Oral health care represents the most unmet health care need. This population has been found to have decreased oral health outcomes compared with the general population.MethodsThe authors used the 2018 adult National Health Interview Survey to assess the association between disability status and dental care use (dental visit within or > 2 years). Disability status was categorized as adults with an intellectual, acquired, or developmental disability (IADD) that limits function, other disability that limits function, or no disability, on the basis of diagnoses of birth defect, developmental diagnosis, intellectual disability, stroke, senility, depression, anxiety, or emotional problem, all causing problems with function.ResultsAdults with an IADD with functional and independence-limiting disabilities experienced higher crude odds of going 2 years or more without a dental visit than adults without disabilities (odds ratio [OR], 2.29; 95% CI, 1.96 to 2.67). This association was part of a significant interaction and was stronger among those with IADDs who could afford oral health care (OR, 1.73; 95% CI, 1.47 to 2.14) than among those who could not afford oral health care (OR, 1.21; 95% CI, 0.88 to 1.67; P value of interaction <.01).ConclusionsAdults with IADDs have decreased access to oral health care compared with adults with other disabilities or without disabilities. The inability to afford oral health care lessens the impact of disability status.Practical ImplicationsDentists can use this study to understand the implications of IADD diagnoses on dental care use and make efforts to facilitate care for these patients.
