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.     

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.     

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.     

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.     

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.     

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.     

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.     

Caries risk and social determinants of health: A big data report

BackgroundOral health is influenced by social determinants of health (SDH), predisposing people and communities to greater risk of developing caries. This study evaluated the association between caries risk in adults and SDH such as ZIP Codes, systemic diseases, payment methods, and race or ethnicity.MethodsThe BigMouth Dental Data Repository (n = 57,211) was used to extract clinical and SDH data from patients’ dental electronic health records for 2019. Caries risk categories were used as ZIP Code data was merged with the Social Deprivation Index, a composite measure of area-level deprivation based on 7 demographic characteristics collected in the American Community Survey.ResultsThe results showed that the odds of being in the high caries risk group were higher for people in the 49- to 64-year age group (adjusted odds ratio [aOR], 2.24; 95% CI, 2.08 to 2.40; P ≤ .001), men (aOR, 1.19; 95% CI, 1.13 to 1.25; P ≤ .001), people who had comorbidities (diabetes: aOR, 1.16; 95% CI, 1.08 to 1.24; P ≤ .001; cardiovascular disease: aOR, 1.40; 95% CI, 1.32 to 1.50), and people with an Social Deprivation Index score above the 75th percentile (aOR, 2.39; 95% CI, 2.21 to 2.58; P ≤ .001). In addition, Hispanic and Black people had higher odds of being at high caries risk than other races or ethnicities (Hispanic: aOR, 3.05; 95% CI, 2.32 to 4.00; Black: aOR, 2.05; 95% CI, 1.02 to 4.01).ConclusionsThis study shows the association of caries risk with higher social deprivation, reinforcing the role of structural and upstream factors in oral health. This study is unique in using recorded ZIP Code information and assessing caries risk levels for those regions.Practical ImplicationsThe physical and structural environment should be considered contributors to caries risk in people.     

Update on the prevalence of untreated caries in the US adult population, 2017-2020

BackgroundUntreated caries is a prevalent disease that is associated with a substantial health and economic burden. Many past efforts have assessed the epidemiology of untreated caries, and this study provides the most up-to-date figures on the distribution and determinants of the disease in the adult US population for the period 2017 through 2020.MethodsUsing data from the 2017-2020 National Health and Nutrition Examination Survey, the author derived estimates for untreated caries prevalence in the adult US population. The author conducted subgroup analyses to assess how the epidemiology differed between coronal and root caries and how the disease was distributed among population subgroups.ResultsOn the basis of a weighted sample representative of 193.5 million adults, the prevalence of untreated caries was found to be 21.3%. Specific prevalence of coronal and root caries were 17.9% and 10.1%, respectively. Caries was most prevalent in those aged 30 through 39 years (25.2%) and 40 through 49 years (22.3%), men (23.5%), those of other (36.5%) or non-Hispanic Black (35.6%) race or ethnicity, those with family income to poverty ratio of 0.5 through 1.0 (46.2%) or less than 0.5 (37.3%), those with educational attainment less than high school graduation (39.6%), those who did not have health insurance (42.1%), and those who were underweight (25.1%) or obese (23.5%).ConclusionsUntreated caries is present in more than 1 in 5 adults within the US population and is disproportionately distributed among those of lower socioeconomic status.Practical ImplicationsThere is a substantial unmet health care need in the US adult population for the prevention and management of untreated caries, and public health efforts should aim particularly to address disease within those subgroups who are at a disproportionately high risk.     

Smoking-cessation advice from dental care professionals and its association with smoking status: Analysis of National Health and Nutrition Examination Survey 2015-2018

BackgroundSmoking remains a major contributor to mortality and morbidity. Dental care professionals are positioned to help patients quit smoking. Results of clinical trials have shown the efficacy of dental care professionals’ smoking-cessation advice; however, the evidence of its effectiveness in the general population in the United States is limited. The authors examined the association between smoking-cessation advice from dental care professionals and quitting behaviors of adult smokers in the general population.MethodsThe authors used an observational study design with data from the National Health and Nutrition Examination Survey for the years 2015 through 2018. The authors included 1,024 respondents 18 years and older who were current or former smokers who quit smoking within the past 12 months and reported a dental visit within the past 12 months.ResultsAmong the study sample, 44.6% received smoking-cessation advice from a dental care professional. The authors found no significant association between smoking-cessation advice and any attempt to quit smoking (as a binary outcome; adjusted odds ratio, 1.11; 95% CI, 0.68 to 1.80; P = .677). Although respondents who received smoking-cessation advice reported 18% more quit attempts (on a continuous scale; adjusted rate ratio, 1.18; 95% CI, 1.00 to 1.39, P = .05), smoking-cessation advice was not associated with smoking abstinence beyond 6 months.ConclusionsReceiving smoking-cessation advice from a dental care professional was associated with more attempts to quit smoking but not with abstinence of 6 months or longer.Practical ImplicationsAdditional efforts seem to be needed for smoking cessation in dental practices. Implementing enhanced incentive programs or promoting tobacco-use cessation certification in dental education may be an effective strategy to enhance dental professionals’ knowledge and skills in providing additional support to their patients.     

The role of sugar-rich diet and salivary proteins in dental plaque formation and oral health

BackgroundDental plaque is a complex colorless film of bacteria that develops on the surfaces of teeth. Different mechanisms of microbial adhesion to tooth surfaces exist. Both non-specific and specific types of adherence have been anticipated.HighlightThe present review evaluated the effect of sugar-rich diet and salivary proteins on oral hygiene and dental plaque development.ConclusionThe oral microbiota is essential for maintaining and reestablishing a healthy oral cavity. Different types of sugars have different effects on the inhibition and formation of dental plaque. The peptides, proteins, and amino acids secreted by parotid glands in the oral cavity facilitate neutralizing the acidity in dental plaque and preventing dental caries. A properly balanced diet is crucial for both a healthy oral cavity and the oral microbiome.     

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.     

Pediatric dental care use and parent- or caregiver-rated oral health among Alabama children enrolled in Medicaid

BackgroundReducing caries and improving access to dental care is a public health challenge. Understanding low use of dental care is of critical importance. This study estimated parent- or caregiver-reported prevalence and identified factors associated with children’s dental care use, including the association with children’s oral health.MethodsA cross-sectional analysis of children enrolled in Medicaid in Alabama, using data from the 2017 statewide Consumer Assessment of Healthcare Providers and Systems Health Plan Survey, was conducted. Associations were measured using adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) from logit regression and generalized linear model postestimation of least-squares means.ResultsThe 6-month prevalence of children receiving dental care was 70.4%. Children aged 0 through 3 years (aPR, 0.72; 95% CI, 0.53 to 0.91) had lower prevalence of care than other age groups. The prevalence of low-rated oral health was 9.2%. Low-rated oral health was associated with not receiving dental care (aPR, 1.50; 95% CI, 1.12 to 1.87) and parental education of 8th grade or less (aPR, 2.59; 95% CI, 1.20 to 3.98). Falsification tests determined that dental care use was not associated with ratings for overall health (aPR, 1.18; 95% CI, 0.83 to 1.52) or emotional health (aPR, 1.06; 95% CI, 0.79 to 1.33).ConclusionsIt was observed that children not receiving dental care had low-rated oral health; however, as a cross-sectional study, it was not possible to assess the temporality of this relationship.Practical ImplicationsOral health care providers should continue to recognize their role in educating parents and providing anticipatory guidance on children’s oral health.     

Work site access to fluoridated tap water and retail beverages: An assessment of the University of California,San Francisco campuses

BackgroundEmployees with fluoridated drinking water access at work can reap oral health benefits. The purpose of this study was to assess the availability, appeal, and promotion of fluoridated tap water in publicly accessible spaces compared with retail beverages at the University of California, San Francisco.MethodsThe authors collected information on beverages available in publicly accessible spaces at University of California, San Francisco hospitals and campuses in San Francisco, California, from December 2019 through February 2020 using a web-based survey tool. Data collected included fluoridated water and retail beverage locations; type of water or retail beverage source; number of water sources per station; cleanliness, flow, and any obstruction of water sources; proximity of water stations to retail beverage locations; signage near the beverage locations about water and beverage consumption; and type of retail beverages available.ResultsFluoridated water stations were identified in 230 locations and had 377 water sources (for example, traditional drinking fountain and motion-sensor bottle-filling station). One water station was available for every 80 students and employees; however, 25% were obstructed, dirty, or had unsatisfactory flow. Approximately 1 in 5 watercoolers lacked disposable cups. Of 41 retail beverage locations identified, 29% had a water station within sight. Only 11% of beverage locations had signage encouraging healthier beverage choices.ConclusionsA systematic assessment of work site access to fluoridated water can provide actionable evidence to improve availability, appeal, and promotion.Practical ImplicationsThis study provides a model to assess work site availability of fluoridated drinking water that can be used for future evaluations.     

Association between first oral examination characteristics and dental treatment needs in privately insured children: A claims data analysis

BackgroundEarly childhood caries (ECC) remains the most common, preventable infectious disease among children in the United States. Screening is recommended after the eruption of the first tooth, but it is unclear how the age at first dental examination is associated with eventual restorative treatment needs. The authors of this study sought to determine how provider type and age at first dental examination are associated longitudinally with caries experience among children in the United States.MethodsDeidentified claims data were included for 706,636 privately insured children aged 0 through 6 years as part of the nationwide IBM Watson Health Market Scan (2012-2017). The authors used Kaplan-Meier survival analysis to describe the association between the age of first visit and restorative treatment needs.ResultsA total of 21% of this population required restorative treatment, and the average age at first dental examination was 3.6 years. A multivariable Cox proportional hazards model showed increased hazard for restorative treatment with age at first dental visit at 3 years (hazard ratio, 2.05; 95% CI, 1.97 to 2.13) and 4 years (hazard ratio, 3.99; 95% CI, 3.84 to 4.16).ConclusionThe high proportion of children requiring restorative treatment and late age at first dental screening show needed investments in educating general dentists, medical students, and pediatricians about oral health guidelines for pediatric patients.Practical ImplicationsCommunicating the importance of children establishing a dental home by age 1 year to parents and health care professionals may help reduce disease burden in children younger than 6 years.     

Impact of visual inspection and radiographs for caries detection in children through a 2-year randomized clinical trial: The Caries Detection in Children–1 study

BackgroundVisual inspection (VIS) with radiographic examination (RAD) is the recommended diagnostic strategy for detecting caries in children; however, this recommendation is based on accuracy studies. The authors conducted a clinical trial to compare the detection and subsequent treatment of carious lesions in primary molars performed with VIS alone and with RAD.MethodsChildren (3-6 years old) were randomly assigned to 2 groups according to the diagnostic strategy used for caries detection on primary molars: VIS or RAD. Participants were diagnosed and treated according to the management plan related to the allocated group. The primary outcome was the number of new operative interventions during the 2-year follow-up period. Other secondary outcomes were also compared. Comparisons were performed with Mann-Whitney test using an intention-to-treat approach.ResultsOf the 252 children included and randomized, 216 were followed-up after 2 years (14.3% attrition rate). There was no difference between the groups for the primary outcome (P = .476). For the secondary outcomes, the RAD group had more restoration replacements (P = .038) and more restorations performed since the beginning of the study (P = .038) compared with the VIS group. In addition, the RAD group had a higher number of false-positive results than the VIS group (P < .001).ConclusionsSimultaneous use of VIS and RAD for caries diagnosis in primary molars of children who seek dental treatment does not provide additional benefits compared with VIS alone.Practical ImplicationsDentists should perform VIS only, not RAD, for detecting carious lesions in preschool-aged children.ClinicalTrials.gov: NCT02078453.     

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 impact of COVID-19 lockdown on maintenance of children's dental health: A questionnaire-based survey

BackgroundThe COVID-19 pandemic has been associated with several changes in maintenance of children's dental health. The aim of this study was to evaluate the extent of these changes.MethodsParents were asked to respond anonymously to a questionnaire regarding alterations in their children's oral habits, such as frequency of eating and drinking, toothbrushing, signs of stress, and receiving oral health care during the lockdown period. The participants were reached either during their visit to the clinics or via the social media groups of the authors.ResultsThere were 308 parents of children aged 1 through 18 years who responded to the questionnaires. The authors found associations between increased frequency of eating and drinking, decreased frequency of toothbrushing, and postponing oral health care. Among the children, 11% experienced more frequent oral signs of stress, such as temporomandibular disorder and aphthous stomatitis, during the lockdown. Although children from all age groups ate and drank more frequently between meals, younger children received a diagnosis of carious lesions more often during the lockdown (P = .015).ConclusionsDuring the lockdown, many children changed their eating, drinking, and toothbrushing habits and, thus, increased their risk of developing caries.Practical ImplicationsDuring pandemic-associated re-care visits or recall visits, it is imperative to conduct a detailed interview regarding changes in oral health habits. In children at high risk, dentists recommended more diagnostic and preventive measures to prevent deterioration of their oral health. Moreover, dentists should put more emphasis on motivational interviewing to help children resume healthier routines after the lockdown.     

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.
