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.     

Association between primary headaches and temporomandibular disorders: A systematic review and meta-analysis

BackgroundThe primary objective of this systematic review was to answer the following question systematically: Is there any association between primary headaches (PHs) and temporomandibular disorders (TMDs) in adults?Types of Studies ReviewedThe protocol was registered with the International Prospective Register of Systematic Reviews. The authors performed the search in 6 main databases and 3 gray literature sources. The included articles had to have adult samples. PHs must have been diagnosed using the International Classification of Headache Disorders, and TMDs must have been diagnosed using Research Diagnostic Criteria for Temporomandibular Disorders, Diagnostic Criteria for Temporomandibular Disorders, or International Classification of Orofacial Pain. Risk of bias was evaluated using the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument tools. The meta-analysis was performed using Review Manager software, Version 5.4. Certainty of evidence was screened according to Grading of Recommendations Assessment, Development and Evaluation.ResultsNine of 2,574 articles reviewed met the inclusion criteria for qualitative analysis and, of these, 7 met the inclusion criteria for quantitative analysis. Odds ratios (ORs) for painful TMD and tension-type headache (OR, 1.94 [95% CI, 0.56 to 6.76] to OR, 7.61 [95% CI, 1.84 to 31.48]), migraines (OR, 4.14 [95% CI, 1.38 to 12.43] to OR, 5.44 [95% CI, 3.61 to 8.21]), and chronic headaches (OR, 40.40 [95% CI, 8.67 to 188.15] to OR, 95.93 [95% CI, 12.53 to 734.27]) were calculated. Articular TMDs without pain were evaluated in 2 articles, and both did not show positive association with tension-type headache nor migraine. Three studies were classified as moderate risk of bias and 6 as low risk of bias. The certainty of evidence varied between very low and low.Conclusions and Practical ImplicationsRecognizing the positive association between painful TMD and PHs can help dentists and physicians treat the pain and avoid it, or recommend the patient to a specialist.     

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.     

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.     

Review of visceral throat and chest disorders causing nonodontogenic orofacial pain

BackgroundThe purpose of this narrative review was to show that referred orofacial pain can be the chief symptom or a prominent symptom of visceral diseases of the chest and throat, with implications for dental and medical practice.Types of Studies ReviewedA search of PubMed was performed to identify dentally relevant clinical case reports and case series using the following terms: jaw pain, orofacial pain, toothache, temporomandibular disorders, otalgia, neuralgia, and neuropathic pain crossed with angina, myocardial infarction, carotid artery, esophagus, mediastinum, thyroid, heart, pericardium, aorta, lung, thymus gland, and stomach.ResultsNumerous acute, visceral disorders of the throat and chest have been reported to produce pain in the orofacial region, which may be difficult to distinguish from dental-related diseases on the basis of symptoms alone. Chest organs and structures reported to cause such pain include the heart, aorta, esophagus, stomach, lungs, and mediastinum. Throat organs and structures reported to cause pain in the orofacial region include the thyroid gland, carotid arteries, and vagus and glossopharyngeal nerves. Coronary artery diseases, aortic and carotid dissection, mediastinal tumors, subacute thyroiditis, and gastroesophageal reflux disease have a predilection for referring pain orofacially.Conclusions and Practical ImplicationsMisdiagnosis of referred visceral orofacial pain can lead to delayed diagnosis and unnecessary treatment. Dentists can play a key role in the management of these conditions by means of ruling out odontogenic facial pain, promptly referring patients to medical specialists, and educating patients. Future research is needed to determine the incidence and mechanism of orofacial pain in these disorders. Visceral pain referred to the orofacial region may not be as rare a phenomenon as is sometimes assumed.     

The contribution of different permanent tooth types to untreated caries: Implications for public health surveillance and prevention

BackgroundUntreated caries (UC), although highly prevalent, is largely preventable. Information on the contribution of different teeth to UC prevalence and severity could be helpful in evaluating UC surveillance protocols and the relative benefits of caries prevention interventions.MethodsThe authors combined data from 3 cycles (2011-2016) of the National Health and Nutrition Examination Survey for participants aged 6 through 11 years, 12 through 19 years, 20 through 34 years, 35 through 49 years, 50 through 64 years, 65 through 74 years, and 75 years and older. For each age group the authors calculated the contribution of successive permanent tooth types (for example, first molars and second molars) to UC prevalence and severity.ResultsUC prevalence and the percentage of prevalence detected by means of screening molars were, respectively, 5% and 95% among participants aged 6 through 11 years; 16% and 92% among participants aged 12 through 19 years; 29% and 86% among participants aged 20 through 34 years; 26% and 70% among participants aged 35 through 49 years; 21% and 48% among participants aged 50 through 64 years; 16% and 36% among participants aged 65 through 74 years; and 17% and 25% among participants 75 years and older. Among adults aged 50 years and older, no teeth appeared to capture a disproportionate share of UC prevalence. Molars accounted for 87%, 79%, and 56% of severity among participants aged 6 through 11 years, 12 through 19 years, and 20 through 34 years, respectively. After age 34 years, molars accounted for less than 50% of severity.ConclusionsMolars are the tooth type most susceptible to UC well into adulthood.Practical ImplicationsMolars could be used as sentinel teeth for surveillance of UC and adults could benefit from caries prevention that targets molars.     

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.     

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.     

Dental health status,use, and insurance coverage among adults with chronic conditions: Implications for medical-dental integration in the United States

BackgroundThe authors examined potential benefits and difficulties in integrating oral health care and medical care for adults with chronic conditions (CCs).MethodsThe authors used National Health and Nutrition Examination Survey 2009-2016 data to estimate crude (age- and sex-standardized) and model-adjusted estimates to examine the association between dental disease (severe tooth loss, untreated caries) and chronic disease (≥ 3 CCs, fair or poor health) and Medical Expenditure Panel Survey 2014-2016 data to estimate crude estimates of past-year medical and dental use and financial access according to CC status. Reported differences are significant at P < .05.ResultsNational prevalences of reporting fair or poor health and 3 or more CCs were both approximately 15%. Standardized prevalence of dental disease was notably higher among adults reporting CCs than those not reporting. After controlling for covariates, the magnitude of the association was substantially lower, although the association remained significant. Adults with CCs were approximately 50% more likely to report having a past-year medical visit and no dental visit than those not reporting CCs. Among adults reporting CCs, prevalence of having no private dental insurance and low income was approximately 20% and 60% higher, respectively, than that among adults not reporting CCs.ConclusionsAdults with CCs had higher prevalence of dental disease, past-year medical visit and no dental visit, and limited financial access.Practical ImplicationsMedical visits may be the only opportunity to provide dental education and referrals to adults with CCs. Improved medical-dental integration could improve oral health care access and oral health among these adults who are at higher risk of dental disease.     

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.     

Emergency department visits for infectious oral conditions in Massachusetts, 2014 through 2018

BackgroundThe authors aimed to measure population-based preventable emergency department (ED) visits related to infectious oral conditions (IOCs) in Massachusetts and to examine the associated sociodemographic factors to support prevention efforts.MethodsA statewide retrospective analysis of ED visits related to IOCs in Massachusetts from 2014 through 2018 was conducted using a Center for Health Information and Analysis database. The authors described patients' characteristics, dental diagnoses frequencies, emergency severity, lengths of stay, associated treatment, and costs. Multilevel logistic regression was used to assess factors associated with IOC visits.ResultsIOC visits in 2014 through 2018 were 1.2% (149,777) of the total ED visits, with an estimated cost of $159.7 million. There was an annual decline in the prevalence of IOC visits from 2014 through 2018. After adjusting for sociodemographic factors, odds of IOC were higher among males (adjusted odd ratio [AOR], 1.26; 95% CI, 1.24 to 1.27), non-Hispanic Blacks compared with non-Hispanic Whites (AOR, 1.03; 95% CI, 1.02 to 1.06), people residing in dental health care professional shortage areas (AOR, 1.06; 95% CI, 1.04 to 1.07), public insurance beneficiaries (AOR, 1.90; 95% CI, 1.87 to 1.93), or uninsured (AOR, 2.60; 95% CI, 2.54 to 2.66) compared with privately insured.ConclusionsThere was an annual decline in the prevalence of IOC visits from 2014 through 2018. Higher odds of IOC visits were associated with young adults, Black patients, uninsured people, public insurance beneficiaries, and people who reside in dental health care professional shortage areas.Practical ImplicationsThe authors provided statewide data to support proposed policies to improve oral health care in Massachusetts. IOCs are mostly preventable, but well-coordinated care between medicine and dentistry is integral for prevention.     

Burnout in oral medicine and orofacial pain residents

BackgroundThe authors sought to identify the prevalence of burnout in oral medicine (OM) and orofacial pain (OFP) residents and investigate potential contributing factors.MethodsA cross-sectional questionnaire-based study was conducted. An anonymous 22-item online survey was emailed to the residents of all Commission on Dental Accreditation–accredited OM and OFP residency programs in the United States. Abbreviated Maslach Burnout Inventory was included to gauge the following details of burnout: emotional exhaustion (EE), depersonalization (DP), and personal accomplishment. Questions also addressed the impact of residency program characteristics, work-life balance, and possible discrimination or abuse on burnout.ResultsSix OM and 12 OFP programs (72 residents) were contacted, and 46 residents responded (response rate, 64%). Overall prevalence of burnout was 35% (29% in OM residents, 40% in OFP residents). High EE burnout was noted in 57% of residents, high DP burnout in 11% of residents, and high personal accomplishment burnout in 59% of residents. Working for fewer than 40 hours per week was significantly associated with low DP burnout (P < .05). Moderate to high DP burnout was more prevalent in men and unmarried residents (whether in a relationship or not) were more likely to experience moderate to high EE burnout (P < .05).ConclusionsBurnout among OM and OFP residents is an emerging concern due to its detrimental effect on the physical and mental well-being of the residents. To the authors’ knowledge, this study is the first to report burnout prevalence in the 2 most recent dental specialties recognized by the American Dental Association in 2020.Practical ImplicationsEarly detection of signs of burnout among residents would allow program faculty and administrators to provide required support and resources.     

Variations in root canal morphology of permanent incisors and canines among Asian population: A systematic review and meta-analysis

ObjectivesThis systematic review was designed to measure the pooled prevalence of morphological variations in the root canal of permanent incisors and canines among Asian adults.MethodsAn electronic search was conducted in the PubMed, Scopus, and EBSCO databases, and relevant studies were included. Studies reporting on the Vertucci canal configuration (types I to VIII) were included. A weighted proportion (pooled prevalence) with 95% confidence interval was calculated for each canal type, and the outcome was stratified based on country, technique of assessment, gender, and age.ResultsSixty articles were included in the final review. In all types of maxillary anterior teeth, the pooled prevalence of type I canal configuration was greater than 97%, whereas mandibular central incisor, lateral incisor, and canines had a prevalence of 78.4%, 69.2%, and 91.1%, respectively. Studies considering mandibular anterior teeth as a single entity had a lower prevalence of type I configuration (70.1%). Variations in root canal configurations were also observed between countries. Among gender, males had a significantly lower prevalence of type I and a higher prevalence of type II and III canal configurations in the mandibular anterior teeth. A variation in canal types was also noted with advancing age, with younger age groups showing more variations.ConclusionThe majority of maxillary and mandibular anterior teeth have type I Vertucci canal configuration, but variations in mandibular anterior teeth, especially lateral incisors, are also common. Variations were also observed among population, gender, age, and prevalence based on the diagnostic techniques used.     

Comprehensive oral care improves treatment outcomes in male and female patients with high-severity and chronic substance use disorders

BackgroundUsing data from a workforce training program funded by the Health Resources and Services Administration, the authors de-identified pre- and posttreatment assessments of high-severity and chronic substance use disorders (SUDs) to test the effect of integrated comprehensive oral health care for patients with SUDs on SUD therapeutic outcomes.MethodsAfter 1 through 2 months of treatment at a SUD treatment facility, 158 male self-selected (First Step House) or 128 randomly selected sex-mixed (Odyssey House) patients aged 20 through 50 years with major dental needs received integrated comprehensive dental treatment. The SUD treatment outcomes for these groups were compared with those of matched 862 male or 142 sex-mixed patients, respectively, similarly treated for SUDs, but with no comprehensive oral health care (dental controls). Effects of age, primary drug of abuse, sex, and SUD treatment facility–influenced outcomes were determined with multivariate analyses.ResultsThe dental treatment versus dental control significant outcomes were hazard ratio (95% confidence interval [CI]) 3.24 (2.35 to 4.46) increase for completion of SUD treatment, and odds ratios (95% CI) at discharge were 2.44 (1.66 to 3.59) increase for employment, 2.19 (1.44 to 3.33) increase in drug abstinence, and 0.27 (0.11 to 0.68) reduction in homelessness. Identified variables did not contribute to the outcomes.Conclusions and Practical ImplicationsImprovement in SUD treatment outcomes at discharge suggests that complementary comprehensive oral health care improves SUD therapeutic results in patients with SUDs. Integrated comprehensive oral health care of major dental problems significantly improves treatment outcomes in patients whose disorders are particularly difficult to manage, such as patients with SUDs.     

Efficacy of adjuvant ozone therapy in reducing postsurgical complications following impacted mandibular third-molar surgery: A systematic review and meta-analysis

BackgroundResults from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis.MethodsThe authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence.ResultsPatients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, –3.94 to –1.56) and at 7 days (95% CI, –1.67 to –0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of –0.44 at 24 hours, 0.63 at 72 hours, and –0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, –1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, –0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, –1.34 to 4.18; 4 studies, 133 patients).Practical ImplicationsEvidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.     

Steroid supplementation before minor oral surgical procedures in patients taking long-term glucocorticoids: A triple-blinded,randomized, placebo-controlled trial

BackgroundPatients undergoing long-term glucocorticoid therapy are administered additional glucocorticoids before minor dental procedures, although this is not supported by evidence. The authors designed this study to validate the hypothesis that routine blanket glucocorticoid supplementation is unnecessary during minor oral surgical procedures under local anesthesia.MethodsThe authors recruited 270 patients into 3 groups (1:1:1 allocation) from the dental outpatient department. Primary outcomes were changes in hemodynamic parameters and frequency of adverse events among the 3 groups. The secondary outcome was the association of preprocedural stress and procedural pain with periprocedural adverse events in the long-term glucocorticoid therapy group (groups I and II).ResultsNo clinically relevant changes in hemodynamic parameters among the 3 groups were found. The authors also found low periprocedural adverse events in all 3 groups combined (n = 1), so they did not explore the secondary outcomes further.ConclusionsAmong patients undergoing long-term glucocorticoid therapy for indications other than primary adrenal insufficiency, elective minor oral surgical procedures can be performed safely with only their daily dose of glucocorticoid when their medical conditions are optimized. Routine additional glucocorticoid supplementation appears unnecessary. The results of the study also revealed opportunities for value addition by means of integrating oral health care with medical follow-up for patients with multiple co-occurring medical conditions.Practical ImplicationsRoutine blanket glucocorticoid supplementation among patients taking a long-term glucocorticoid for indications other than primary adrenal insufficiency appears unnecessary before minor oral surgical procedures under local anesthesia. This clinical trial was registered at Clinical Trial Registry-India. The registration number is CTRI/2017/02/007779.     

Association between metabolic syndrome and tooth loss: A systematic review and meta-analysis

BackgroundThe authors conducted a systematic review and meta-analysis to verify the existence and level of scientific evidence concerning the association between metabolic syndrome (MetS), as the main exposure, and tooth loss (TL), as the outcome.Types of Studies ReviewedThrough electronic databases and partially through gray literature, the authors identified observational studies in adults. The authors used no date or language restrictions. The authors evaluated the studies’ methodological quality by using the Newcastle-Ottawa Scale. The authors conducted a random-effects model meta-analysis. The authors assessed the quality of evidence by using the Grading of Recommendations Assessment, Development and Evaluation criteria.ResultsTwelve studies met the eligibility criteria, and 9 were retained for the meta-analysis. Most were cross-sectional studies with good methodological quality. Participants with MetS had fewer teeth (standardized mean difference, −2.77; 95% confidence interval, −4.56 to −0.98) and an increased likelihood of lacking functional dentition (odds ratio, 2.37; 95% confidence interval, 1.89 to 2.96) than did those without MetS. The overall quality of evidence was very low.Conclusions and Practical ImplicationsBetter-conducted longitudinal studies are necessary to establish a causal relationship between MetS and TL to inform the best strategies to prevent TL in populations with MetS.     

Prevalence of ankyloglossia according to different assessment tools: A meta-analysis

BackgroundPrevalence of ankyloglossia may vary depending on the assessment tool. This systematic review aimed to evaluate the prevalence of ankyloglossia in distinct age groups according to different assessment tools.Types of Studies ReviewedNine electronic databases were searched from inception through November 2021 without restrictions of language or year of publication. Paired independent reviewers selected cross-sectional and cohort studies reporting the diagnosis of ankyloglossia, extracted data, and assessed methodological quality. The number of patients with ankyloglossia and the sample were extracted to calculate the overall prevalence of ankyloglossia and 95% CI. The authors calculated the prevalence of ankyloglossia per assessment tool, age group, and sex. They assessed the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach.ResultsSeventy-one studies were included. Seven different diagnostic tools were used. The overall prevalence of ankyloglossia was 5% (95% CI, 4.0% to 5.0%) and ranged from 2% (using an unspecific tool) to 20% (Coryllos classification). The prevalence per age group was higher in infants (7%). The prevalence ratio was 1.34 (95% CI, 1.17 to 1.54) for boys, with very low certainty of evidence.Practical ImplicationsThe prevalence of ankyloglossia is higher among infants and differs depending on the assessment tool used for the diagnosis. It is uncertain whether boys are more affected by ankyloglossia than girls.
