Trends in use of dental care provider types and services in the United States in 2000-2016: Rural-urban comparisons

BackgroundThe authors conducted a study to assess recent trends in dental care provider mix (type of dental professionals visited) and service mix (types of dental procedures) use in the United States and to assess rural-urban disparities.MethodsData were from the 2000 through 2016 Medical Expenditure Panel Survey. The sample was limited to respondents who reported at least 1 dental visit to a dental professional in the survey year (N = 138,734 adults ≥ 18 years). The authors estimated rates of visiting 3 dental professionals and undergoing 5 dental procedures and assessed the time trends by rural-urban residence and variation within rural areas. Multiple logistic regression was used to assess the association between rural and urban residence and service and provider mix.ResultsA decreasing trend was observed in visiting a general dentist, and an increasing trend was observed in visiting a dental hygienist for both urban and rural residents (trend P values < .001). An increasing trend in having preventive procedures and a decreasing trend in having restorative and oral surgery procedures were observed only for urban residents (trend P values < .001). The combined data for 2000 through 2016 showed that rural residents were less likely to receive diagnostic services (adjusted odds ratio [AOR], 0.82; 95% confidence interval [CI], 0.72 to 0.93) and preventive services (AOR, 0.87; 95% CI, 0.78 to 0.96), and more likely to receive restorative (AOR, 1.11; 95% CI, 1.02 to 1.21) and oral surgery services (AOR, 1.23; 95% CI, 1.11 to 1.37).ConclusionsAlthough preventive dental services increased while surgical procedures decreased from 2000 through 2016 in the United States, significant oral health care disparities were found between rural and urban residents.Practical ImplicationsThese results of this study may help inform future initiatives to improve oral health in underserved communities. By understanding the types of providers visited and dental services received, US dentists will be better positioned to meet their patients’ oral health needs.     

Prevalence and mean number of teeth with amalgam and nonamalgam restorations,United States, 2015 through 2018

BackgroundAmalgam has been used for more than 150 years as a safe and reliable restorative material. The authors described the occurrence of amalgam and nonamalgam restorations in the United States in primary and permanent teeth across age groups and according to sociodemographic characteristics.MethodsThe authors used clinical examination data from the National Health and Nutrition Examination Survey 2015-2018 for participants 2 years and older (n = 17,040). The authors estimated the prevalence and mean number of amalgam and nonamalgam restorations in primary and permanent teeth according to age groups (2-5 years, 6-11 years, 12-15 years, 16-19 years, 20-39 years, 40-59 years, 60-79 years, and ≥ 80 years), race and ethnicity, federal poverty guideline, education, and pregnancy status.ResultsThe prevalence of amalgam restorations ranged from 4% through 69%. Overall, amalgam restorations were more prevalent in children and adolescents from racial and ethnic minority groups and families at lower poverty levels and with lower education. The mean number of teeth with nonamalgam restorations was higher than those with amalgam restorations in primary teeth of children aged 6 through 11 years, permanent teeth of those 12 through 15 years and 20 through 39 years, and women aged 20 through 49 years, regardless of pregnancy status. The mean number of amalgam restorations was higher than that for nonamalgam restorations in older age groups.ConclusionsNonamalgam restorations were the most common in the primary teeth of children older than 5 years and in the permanent teeth of adults younger than 40 years. Amalgam restorations were more common in older adults. Amalgam and nonamalgam restorations were equally common in children younger than 5 years.Practical ImplicationsThe study findings suggest a shift from amalgam to alternative restorative materials in the United States.     

A survival analysis of primary second molars in children treated under general anesthesia

BackgroundThe authors examined time to need new treatment of primary second molars in very young children treated under general anesthesia (GA).MethodsDuring this retrospective chart review, the authors examined patients aged 2 through 4 years with severe early childhood caries (ECC) who received dental treatment under GA. Primary second molars were tracked in periodic recall visits after GA for 6 through 89 months. Using a random-effects Cox proportional hazards model, the authors compared hazards of teeth requiring new treatment based on treatments received at GA.ResultsOf 3,166 primary second molars included in the study, 367 (12%) were not erupted, 77 (2%) received topical fluoride only, 873 (28%) received a pit and fissure sealant, 242 (8%) received a composite restoration, and 1,607 (50%) received a stainless steel crown (SSC) at GA. SSCs had a survival probability of 98% by 84 months after GA, significantly higher than all other groups (P < .0001). The second molars that were not erupted at GA had the highest hazard, especially within the first 24 months after GA. Teeth that received sealant had longer time to need new treatment than nonsealed teeth; however, at 84 months after GA, only 33% of the sealed teeth did not require additional treatment.ConclusionsPreventive or restorative treatments other than SSCs resulted in need for new treatment in a substantial number of teeth. SSCs had the highest success in this population with severe ECC treated under GA and should be chosen over other restorative options to reduce risk of undergoing repeat dental treatment.Practical ImplicationsAggressive treatment with SCC should be considered for young children with severe ECC especially those who are treated under GA at a young age.     

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.     

Association between vaping and untreated caries: A cross-sectional study of National Health and Nutrition Examination Survey 2017-2018 data

BackgroundWith the rise in the prevalence of electronic cigarette (e-cigarette) and vaping products and the emergence of evidence indicating their cariogenic potential, it is essential to examine the association between vaping and untreated caries at a population level.MethodsThe authors obtained data from the 2017-2018 National Health and Nutrition Examination Survey and investigated the outcome variable—untreated caries—using oral health examination data. The authors applied multiple logistic regression analyses to assess the association between untreated caries and smoking (cigarette smoking, vaping, and both) while controlling for education, race or ethnicity, income, age, sex, and time since previous dental visit.ResultsA total of 4,618 participants were included in the analyses for this cross-sectional study. Participants who currently smoked e-cigarettes were more likely to have untreated caries (odds ratio, 1.69; 95% CI, 1.24 to 2.29) than those who had never smoked, when adjusted for demographic variables. Similarly, dual smokers (e-cigarette and conventional smokers) were more likely to have untreated caries compared with nondual smokers (odds ratio, 2.43; 95% CI, 1.36 to 4.36).ConclusionBoth vaping and dual smoking are associated with an increased occurrence of untreated caries.Practical ImplicationsVaping status should be included as a part of health history questionnaires for patients. Dental professionals should be informed of the potential oral health implications of vaping and, in turn, impart this knowledge to patients.     

Pit-and-fissure sealants on primary molars are a cost savings

BackgroundIn this study, the authors examine the cost-effectiveness of light-polymerized resin-based fluoride sealants on primary molars in high caries risk children younger than 6 years.MethodsThe authors examined the cost-effectiveness of pit-and-fissure sealant (PFS) treatment on primary molars by comparing sealed and unsealed molars treated in the outpatient clinic or operating room. Using 1,884 primary molars followed over a 5-year period, the authors used a mixed-effects regression model to estimate the probability of caries development. They used restricted means to estimate years free of caries for carious molars. They used a decision tree to address uncertainty due to PFS treatment failure, predict the expected value associated with each strategy, and estimate the incremental cost-effectiveness ratio using a 3% discount rate to adjust future cost and outcomes to present value.ResultsOver 5 years, the cost of care was $90 for unsealed molars and $75 for sealed molars. Unsealed molars remained caries free for 4.32 years compared with 4.85 years in sealed molars. The cost-effectiveness of PFS treatment was dominant, leading to a savings of $25 for each caries-free year gained and overall savings of $742 million for the United States dental health system over a 5-year period.ConclusionsPFS treatment is associated with cost savings and a delay in caries development and should be considered in children with high caries risk.Practical ImplicationsPolicy makers should consider reimbursement of PFS treatment on primary molars in high caries risk children.     

Disparities in dental health issues and oral health care visits in US children with tobacco smoke exposure

BackgroundThe objective of the authors was to assess the relationships between tobacco smoke exposure (TSE) and dental health and dental care visits among US children.MethodsThe authors examined 2018-2019 National Survey of Children’s Health data on TSE, dental health, and oral health care visits. Children aged 1 through 11 years (N = 32,214) were categorized into TSE groups: no home TSE (did not live with a smoker), thirdhand smoke (THS) exposure (lived with a smoker who did not smoke inside the home), or secondhand smoke (SHS) and THS exposure (lived with a smoker who smoked inside the home). The authors conducted multivariable logistic regression analyses, adjusting for child age, sex, race or ethnicity, prematurity, caregiver education level, family structure, and federal poverty threshold.ResultsChildren with home SHS and THS exposure were at increased odds of having frequent or chronic difficulty with 1 or more oral health problem (adjusted odds ratio [AOR], 1.59; 95% CI, 1.07 to 2.35; P = .022) and carious teeth or caries (AOR, 1.74; 95% CI 1.14 to 2.65; P = .010) than those with no TSE. Compared with children aged 1 through 11 years with no TSE, children with SHS and THS exposure were 2.22 times (95% CI, 1.01 to 4.87; P = .048) more likely to have not received needed oral health care but at decreased odds of having had any kind of oral health care visit (AOR, 0.55; 95% CI, 0.32 to 0.95; P = .032), including a preventive oral health care visit (AOR, 0.60; 95% CI, 0.36 to 0.99; P = .047).ConclusionsTSE in children is associated with caries and inadequate oral health care visits.Practical ImplicationsThe pediatric dental visit is an opportune time to educate caregivers who smoke about dental health to improve their children’s teeth condition and increase oral health care visits.     

Reducing carious lesions during the first 4 years of life: An interprofessional approach

BackgroundCaries in Peruvian 0- through 3-year-olds is high. The dental profession should collaborate with nurses at mother and child health (MCH) clinics for reducing the disease. In this randomized clinical trial, the authors tested an integrated intervention program implemented by nurses and dentists.MethodsThe authors developed age-specific (0-3 years) oral health–related information and activity record cards and validated them for nurses to use after being educated about oral health issues and mouth inspection. The authors trained dentists in atraumatic restorative treatment. The active intervention group (AG) participated in the integrated intervention program, the passive intervention group (PG) received only the oral health–related information and activity record cards, and the control group (CG) received only a lecture. The examiners assessed caries status according to the Caries Assessment Spectrum and Treatment instrument. The authors used analysis of variance and the Tamhane method to analyze the data.ResultsThe sample consisted of 368 children with a mean age of 3.1 years. The 3-year dropout percentage was 40.5%. The prevalence of cavitated dentin carious lesions was statistically significantly lower in the AG (10.0%, confidence interval [CI] 4.1 to 19.5) than in the PG (60.5%, CI 48.6 to 71.5) and CG (63.0%, CI 50.9 to 74.0) after 3 years (P < .001). Enamel carious lesions (62.9%) were most prevalent in the AG, whereas carious lesions were most prevalent in the PG (28.9%) and CG (32.9%).ConclusionsIncorporation of specific oral health care activities into the existing MCH program, implemented by trained nurses and supported by health center dentists, reduced the burden of caries in 3-year-olds substantially.Practical ImplicationsThe oral health care professionals in Peru should collaborate with personnel of MCH clinics to curb caries in 0- through 3-year-olds.     

Impact of school sealant programs on oral health among youth and identification of potential barriers to implementation

BackgroundSchool sealant programs (SSPs) increase sealant prevalence among children lacking access to oral health care. SSPs, however, are substantially underused. From 2013 through 2018, the Centers for Disease Control and Prevention funded 18 states for SSP activities in high-need schools (≥ 50% free and reduced-price meal program participation). From 2019 through 2020, the authors assessed SSPs' impact in reducing caries and how states expanded SSPs. The authors also discuss potential barriers to expansion.MethodsFor Aim 1, the authors used a published methodology and SSP baseline screening and 1-year retention data to estimate averted caries over 9 years attributable to SSPs. For Aim 2, the authors used state responses to an online survey, phone interviews, and annual administrative reports.ResultsUsing data for 62,750 children attending 18.6% of high-need schools in 16 states, the authors estimated that 7.5% of sound, unsealed molars would develop caries annually without sealants and placing 4 sealants would prevent caries in 1 molar. Fourteen states reported SSP expansion in high-need schools. The 2 most frequently reported barriers to SSP expansion were levels of funding and policies requiring dentists to be present at assessment or sealant placement.ConclusionsThe authors found that SSPs typically served children at elevated caries risk and reduced caries. In addition, the authors identified funding levels and policies governing supervision of dental hygienists as possible barriers to SSP expansion.Practical ImplicationsIncreasing SSP prevalence could reduce caries. Further research on potential barriers to SSP implementation identified in this study could provide critical information for long-term SSP sustainability.     

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.     

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.     

Direct materials for restoring caries lesions: Systematic review and meta-analysis—a report of the American Dental Association Council on Scientific Affairs

BackgroundThe goal of restoring caries lesions is to protect the pulp, prevent progression of the disease process, and restore the form and function of the tooth. The purpose of this systematic review was to determine the effect of different direct restorative materials for treating cavitated caries lesions on anterior and posterior primary and permanent teeth.Type of Studies ReviewedThe authors included parallel and split-mouth randomized controlled trials comparing the effectiveness of direct restorative materials commercially available in the United States placed in vital, nonendodontically treated primary and permanent teeth. Pairs of reviewers independently conducted study selection, data extraction, and assessments of risk of bias and certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. The authors conducted pair-wise meta-analyses to summarize the evidence and calculated measures of association and their 95% CIs.ResultsThirty-eight randomized controlled trials were eligible for analysis, which included data on Class I and Class II restorations on primary teeth and Class I, Class II, Class III, Class V, and root surface restorations on permanent teeth. Included studies assessed the effect of amalgam, resin composite, compomer, conventional glass ionomer cement, resin-modified glass ionomer cement, and preformed metal crowns. Moderate to very low certainty evidence suggested varying levels of effectiveness across restorative materials.Conclusions and Practical ImplicationsOwing to a relatively low event rate across various outcomes indicating restoration failure, there was limited evidence to support important differences between direct restorative materials used in practice.     

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).     

A comparative analysis of public and private dental benefit payer types for the provision and outcomes of root canal therapy on permanent teeth of children and adolescents in Massachusetts

BackgroundDespite substantial increases in dental benefits and improvements in the use of dental services among children and adolescents in the United States, oral health disparities according to dental insurance payer type persist.MethodsThe authors used an all-payer claims (2013-2017) database to perform a comparative analysis of the provision and treatment outcomes of an endodontic procedure (root canal therapy) in the permanent teeth of a pediatric population aged 6 through 18 years, according to dental insurance payer type. Statistical analyses, including logistic regression, Cox proportional hazards regression, and the Kaplan-Meier method, were performed at person and tooth levels.ResultsCompared with privately insured children and adolescents, public-payer children and adolescent beneficiaries were more likely to have had root canal therapy (adjusted odds ratio, 1.91; 95% CI, 1.73 to 2.11) and had poorer treatment outcomes associated with the procedure (adjusted hazard ratio, 2.19; 95% CI, 1.53 to 3.14; P < .0001) during the study period. Those enrolled in private insurance were more likely to receive treatment from an endodontist (specialist in providing root canal therapy) (P < .0001). Amounts allowed and paid by the insurer were significantly higher for private payers (P < .001).ConclusionsThere were significant differences in the provision and outcomes of endodontic treatment between privately and publicly insured children and adolescents.Practical ImplicationsDespite ostensibly equal access to care, differences in the provision of oral health care exist between privately and publicly insured patients. These differences may be contributing to persisting oral health disparities.     

Secular trends in dental services provided by dental therapists and dentists in Southwest Alaska

BackgroundThe goal of the study was to identify secular trends in dental service delivery between dental therapists and dentists in the Yukon-Kuskokwim Delta region of Southwest Alaska, the first area of the United States to authorize dental therapy practice.MethodsElectronic health record transactions from the Yukon-Kuskokwim Health Corporation from 2006 through 2015 (n = 27,459) were analyzed. Five types of dental services were identified using Current Dental Terminology procedure codes: diagnostic, preventive, restorative, endodontic, and oral surgery. Main outcomes were percentages of services provided by dental therapists compared with dentists and population-level preventive oral health care.ResultsThe overall number of diagnostic, preventive, and restorative services in the Yukon-Kuskokwim Delta increased. For diagnostic services, there was a 3.5% annual decrease observed for dentists and a 4.1% annual increase for dental therapists (P < .001). Similar trends were observed for restorative services. For preventive services, there was no change for dentists (P = .89) and a 4.8% annual increase for dental therapists (P < .001). Dental therapists were more likely than dentists to provide preventive care at the population level.ConclusionsDental therapists have made substantial contributions to the delivery of dental services in Alaska Native communities, particularly for population-based preventive care.Practical ImplicationsThe study’s findings indicate that there is a role for dental therapy practice in addressing poor access to oral health care in underserved communities.     

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.     

Impact of motivational interviewing on early childhood caries: A systematic review and meta-analysis

BackgroundThe authors aimed to assess the scientific evidence on motivational interviewing for the clinical reduction of early childhood caries compared with traditional dental health education.MethodsSearch terms were selected on the basis of Medical Subject Headings and non–Medical Subject Headings terms. The main key words were motivational interviewing, early childhood caries, and education. Potentially eligible studies involved the clinical assessment of caries rate in children whose parents or caregivers received motivational interviewing as an intervention. The authors assessed the risk of bias using the Cochrane risk-of-bias tool. In March 2019, the authors performed an electronic database search of literature published in English within the following databases: Scopus, Cochrane, PubMed, and Embase.ResultsOf 329 articles retrieved initially, 14 were eligible for inclusion in the systematic review and 3 articles contributed to the meta-analysis. For statistical analysis, the mean difference of continuous data was analyzed at a 95% confidence interval using the random-effects model.ConclusionsOverall, the evidence presented in this review was limited. Although the results of the meta-analysis showed that motivational interviewing is as effective as dental health education in controlling early childhood caries, we need more and better designed and reported interventions to assess its impact on early childhood caries accurately.     

The effect of diet drinks on caries among US children: Cluster analysis

BackgroundThe effect of sugared beverages on dental caries has been widely studied in dental literature. A major limitation of these studies was examining the beverages as a single source. To overcome this limitation, a few studies used cluster analysis to group people into similar beverage consumption patterns. These studies did not differentiate between sugared beverages and diet drinks. Therefore the aim of this study is to examine the effect of consuming diet drinks on dental caries among US children by using cluster analysis.MethodsIn this cross-sectional study, the authors analyzed the dietary data of children aged 3 through 10 years, using 2 24-hour recall interviews in the 2011-2014 National Health and Nutrition Examination Survey data. Cluster analysis has been used to overcome the limitations of examining the beverages as a single source. Clusters were identified based on the R² statistic and the local peak of pseudo-F statistics. Survey procedure and sample weights were used to account for the complex National Health and Nutrition Examination Survey sampling design.ResultsSix beverage consumption clusters were identified: high soda, high 100% juice, high juice drinks, high diet drinks, high milk, and high water. Regression analysis showed that the high soda cluster had a tendency to increase caries risk (odds ratio [OR], 1.69, 95% confidence interval [CI], 0.9 to 3.1), while the high diet drinks cluster had neutral effect compared with the high water cluster (OR, 0.94, 95% CI, 0.5 to 1.8).ConclusionsThe results of this study suggest that diet drinks have no adverse effect on teeth among US children. Additional well-designed longitudinal studies should be conducted to establish the effect of diet drinks on caries when consumed during childhood.Practical ImplicationsAlthough this study did not show an association between caries and diet drinks, dental practitioners should be cautious about recommending these drinks, as they have been linked to systemic diseases. In addition, the American Academy of Pediatrics and National Academy of Medicine do not recommend that children consume these beverages.     

The association between vitamin D levels and caries experience in children and youth participating in National Health and Nutrition Examination Survey 2011-2016: A cross-sectional study

BackgroundGiven equivocal findings from existing nationally representative studies, the authors sought to determine associations between vitamin D levels and caries experience in US children using updated National Health and Nutrition Examination Survey data.MethodsThe authors used data from 2011-2016 National Health and Nutrition Examination Survey. Vitamin D status was assessed on the basis of the sufficiency thresholds of 50 and 75 nmol/L for serum 25-hydroxyvitamin D (25[OH]D) recommended by the Institute of Medicine (now National Academy of Medicine) and Endocrine Society, respectively. Caries experience was defined as the total number of decayed or filled tooth surfaces (dfs) and decayed, missing, or filled tooth surfaces (DMFS) and a binary measure of any dfs and DMFS. Associations between 25(OH)D and any or total dfs and DMFS were examined in children aged 2 through 5, 6 through 8, 9 through 11, and 12 through 18 years, using multivariable logistic and linear regression models after adjustment for covariates.ResultsChildren aged 2 through 5 years with 25(OH)D above 75 nmol/L experienced fewer total dfs (β = –1.94; 95% CI, –3.60 to –0.28) than those with 25(OH)D below 75 nmol/L. Children 6 through 8 years with 25(OH)D above 75 nmol/L had lower presence of any dfs (odds ratio, 0.59; 95% CI, 0.36 to 0.95) than those with 25(OH)D below 75 nmol/L, and those with 25(OH)D above 50 nmol/L had lower presence of any DMFS (odds ratio, 0.38; 95% CI, 0.19 to 0.79) than those with 25(OH)D below 50 nmol/L. There were no associations of 25(OH)D status with either any or total DMFS in children 12 through 18 yearsConclusionsThere were no consistent associations of 25(OH)D status with caries experience across age groups.Practical ImplicationsVitamin D status was not associated consistently with reduced caries experience.
