Assessing oral health content in nondental professional association websites.

OBJECTIVES: Determine the prevalence and type of oral health (OH) content among nondental health professional associations' websites. METHODS: Fifty-nine organizations were selected from three lists of health professional associations and categorized as physician-, nurse- and other healthcare-related professions. Eight dental search terms were used on searchable websites. Six types of OH information were collected. Websites were assessed for any OH content and comparisons made. Frequencies, chi-square, and Fisher extract test statistics were calculated. RESULTS: Thirty-five (59 percent) of websites had any OH information content. Twenty (34 percent) had OH authored content, 10-19 percent had OH webpages, interest groups, or initiatives, CE courses or webinars, or curriculum information. The term "oral hygiene" gave the greatest yield and "dentistry" the least. No significant differences in existence of "Any OH content" was found between each organization type versus others. CONCLUSION: Many nondental professional associations could increase OH website content and education with assistance from dental organizations.

The Evolving Role of Health Literacy in Improving Oral Health.

This chapter provides a review of the evolution of oral health literacy including its impact on oral health outcomes, the current status of oral health literacy initiatives and future research needs. Using the Healthy People 2010 definition, the chapter describes opportunities needed to improve oral health literacy among health providers as well as individuals/patients, communities and policy-makers. Studies of the two most prevalent dental diseasesâATdental caries and periodontal diseases - reveal that increasing the oral health literacy of the public and health care providers can play a major role in reducing these diseases. Increasing oral health literacy by creating access to accurate knowledge and supporting use of science-based preventive measures is essential. A major part of the chapter describes oral health literacy's influence in the integration of dental and medical care. The chapter provides an extensive list of research needed to further our understanding of the impact of oral health literacy on health disparities and the health of the population.

A Clinical Vignette-Based Study of Physicians' Adherence to Guidelines for Dental Referrals of Young Children.

OBJECTIVES: The American Academy of Pediatrics (AAP) recommends an oral health risk assessment and referral to a dental home by a child's first birthday. We evaluated the adherence of primary care providers (PCPs) to AAP dental referral guidelines for children age <4 years and barriers to implementation of these guidelines. METHODS: A cross-sectional survey of PCPs randomly selected from the 435 practices in North Carolina identified as providing well-child visits for Medicaid children age <4 years was completed in 2013. The PCPs' referral recommendations were assessed using 4 vignettes of 18-month-old children at various risk of dental caries (low, moderate, high, or highest) and different levels of dentist supply (adequate or inadequate). Barriers to guideline adherence specified in the Cabana framework were analyzed for their associations with PCP adherence, using logistic regression models stratified by caries risk and dentist supply. RESULTS: The survey yielded 219 (50%) usable responses from the sample of 435 PCPs. On average for all vignettes, 61% of providers chose a referral recommendation in agreement with guidelines. Underreferral averaged 40%. With adequate workforce, guideline-adherent responses varied from 26% for low-risk children to >90% for high-risk children. An inadequate workforce reduced adherence for most levels of risk. Generally, correct knowledge of risk status, barriers to risk assessment, and pediatric practice were associated with adherence, but not always in the hypothesized direction. CONCLUSIONS: PCPs' adherence to referral guidelines varies according to caries risk and dentist supply, but generally they underrefer low- to moderate-risk patients by a significant degree.

Access to preventive services after the integration of oral health care into early childhood education and medical care.

BACKGROUND: The effect of Early Head Start (EHS) on receipt of preventive oral health services (POHS) from both oral and medical health care providers is not known. METHODS: The authors compared children enrolled in North Carolina EHS programs with similar children enrolled in Medicaid but not EHS on the use of POHS. They analyzed 4 dependent variables (oral assessment by medical health care provider, oral assessment by oral health care provider, fluoride application by medical health care provider, fluoride application by oral health care provider) by using multivariate logistic regression that controlled for covariates. RESULTS: Primary caregivers of children enrolled in EHS (n = 479) and Medicaid (n = 699) were interviewed when children were approximately 10 and 36 months of age. An average of 81% of EHS and non-EHS children received POHS from an oral or medical health care provider at follow-up. EHS children had greater odds of receiving an oral health assessment (odds ratio [OR], 2.33; 95% confidence interval [CI], 1.74 to 3.13) and fluoride (OR, 1.53; 95% CI, 1.16 to 2.03) from an oral health care provider than children not enrolled. EHS children had decreased odds (OR, 0.73; 95% CI, 0.54 to 0.99) of receiving fluoride from a medical health care provider. CONCLUSIONS: Both children enrolled in EHS and community control participants had high rates of POHS, but the source of services differed. EHS children had greater odds of receiving POHS from oral health care providers than non-EHS children. EHS and non-EHS children had equal rates for fluoride overall because of the greater percentage of non-EHS children with medical fluoride visits. PRACTICAL IMPLICATIONS: The integration of POHS in early education and Medicaid medical benefits combined with existing dental resources in the community greatly improves access to POHS.

Implementing an early childhood oral health program in a federally qualified health center in North Carolina.

OBJECTIVES: To examine the Baby Oral Health Program's (bOHP) influence on dental visits for children 0 to 3 years and overall dental visits in four federally qualified health center (FQHC) clinics. METHODS: Using an interrupted time series study design, administrative data were obtained for the year prior and following the intervention. The intervention included dental staff training on early childhood oral health, quality improvement, and monthly visits during the follow-up intervention period. Analysis included descriptive and segmented regression using aggregate patient visit data. RESULTS: A total of 10,400 patients made 26,416 visits over the study period; 1,187 (11 percent) were children ≤3 years. Visit counts in the youngest age group increased 70 percent following the intervention. When controlling for the naturally increasing trend, the intervention added 8.7 (95 percent CI: 4.7, 12.8) early childhood patient-visits per clinic in the last month of the intervention period. The increase in visit counts in the youngest age group had no significant effect on other ages, except for a decline relative to the natural trend in patient-visits among 35-50 year olds (-32.3 less visits) following the intervention. The proportion of visits for all ages by ≤3 year olds increased from 5 to 8 percent following the intervention. CONCLUSIONS: bOHP increased dental visits among children ≤3 years but the finding might be attributable to clinic changes coinciding with bOHP implementation that were not controlled with the study design. Additional studies are needed in populations experiencing challenges accessing dental care.

Bridging the dental-medical divide: Case studies integrating oral health care and primary health care.

BACKGROUND: The National Academies of Sciences, Engineering, and Medicine commissioned an environmental scan describing the status of health care integration of oral health and primary care services. METHODS: The authors conducted an environmental scan of US integration activities with publications from January 2000 through August 2017. They categorized services as preventive oral health services (POHS) provided by medical care providers, POHS provided by dental providers in nondental settings, preventive health services provided by dental providers, or care coordination using dedicated personnel and technology. The authors chose 4 programs as case studies and interviewed key personnel in each program. One case study illustrates each category of integrated services; additional examples describe category variation. RESULTS: The case study involving Into the Mouth of Babes illustrates medical professionals delivering POHS to children. The case study involving Grace Health presents dental hygienists embedded in the obstetrics-gynecology clinic to provide oral screening, prophylaxis, and education to pregnant women. At HealthPartners, medical care providers refer patients with diabetes to dentists and waive copays for periodontal care. The InterCommunity Health Network Coordinated Care Organization uses dedicated patient coordinators, technology, and coordinated payment and referral mechanisms to facilitate care. CONCLUSIONS: Integration of dental and medical care increased access to and coordination of patient care by means of offering health care services traditionally provided by the other profession. PRACTICAL IMPLICATIONS: Integration models demonstrate the incorporation of POHS by primary care professionals, the embedding of dental professionals into primary care clinics, and the incorporation of care coordination to increase the delivery of oral health care. Similarly, dentists identify and refer patients with medical needs or preventive gaps to medical homes.

Absence of a moderating effect of parent health literacy on Early Head Start enrollment and dental use.

OBJECTIVES: To examine the moderating effect of parents' health literacy (HL) on the effectiveness of North Carolina Early Head Start (EHS) in improving children's dental use. METHODS: Parents of 479 children enrolled in EHS and 699 Medicaid-matched parent-child dyads were interviewed at baseline when children were approximately 10 months old and 24 months later. We used in-person computer-assisted, structured interviews to collect information on sociodemographic characteristics, dental use, and administer the Short Assessment of Health Literacy - Spanish and English (SAHL-S&E). This quasi-experimental study tested whether the interaction effect between EHS and parents' HL was associated with dental use. Logit (any use) and marginalized zero-inflated negative binomial count models (number of dental visits) included random effects to account for clustering and controlled for baseline dental use, dental need, survey language, and a propensity score covariate. RESULTS: Nineteen percent of parents in EHS had low literacy compared to 12 percent of parents in the non-EHS group (P < 0.01). The interaction term between EHS and parent's HL was not significant in the adjusted logit model (ratio of aORs 0.98, 95 percent CI: 0.43-2.20) or the adjusted count model (ratio of aRRs 0.88, 95 percent CI: 0.72-1.09). CONCLUSIONS: Parents in EHS had a higher prevalence of low HL compared to non-EHS parents. Parents' HL did not moderate the relationship between EHS and child dental use, suggesting that EHS results in similar improvements in dental use regardless of parent's HL levels.

Prenatal Oral Health Counseling by Primary Care Physicians: Results of a National Survey.

Objectives Limited information exists on the extent oral health is addressed in the context of prenatal care. This study sought to investigate characteristics of primary care physicians (PCP) who provide oral health counseling to pregnant women. Methods The study relied upon data from the 2013 Survey of PCP on Oral Health. Provision of oral health counseling to pregnant women (sometimes vs. rarely/never) was the primary outcome. Covariates included respondents' demographic and practice characteristics, oral health-related training, knowledge, attitudes, preparedness and clinical behaviors. The analytical strategy included bivariate tests and multivariable Poisson regression modeling, accounting for the survey design; inference was based upon marginal effects estimation. Results Two-thirds of PCP (233 out of 366 respondents) reported providing oral health counseling to pregnant women. In bivariate comparisons, female PCP, PCP with oral health-specific instruction during medical training, favorable oral health-related attitudes, behaviors, preparedness, and knowledge were more likely to provide counseling (p < 0.05). Multivariable analyses confirmed the independent associations of female gender [marginal effect = + 9.7 percentage points (p.p.); 95% confidence interval (CI) = 0.0-19.0], years in practice (- 0.4 p.p. for each added year; 95% CI = - 0.09 to 0.0), oral health continuing education (+ 13.2 p.p.; 95% CI = 2.6-23.8), preparedness (+ 23.0 p.p.; 95% CI = 16.9-29.0) and oral health counseling of adult patients with other conditions (+ 8.8 p.p.; 95% CI = 4.6-13.3) with prenatal oral health counseling. Conclusions for Practice A considerable proportion of PCP nationwide counsel pregnant patients on oral health. Provider attributes including education and preparedness appear as promising targets for interventions aimed to enhance pregnant women's oral health and care.

Providers' preferences for pediatric oral health information in the electronic health record: a cross-sectional survey.

BACKGROUND: The majority of primary care physicians support integration of children's oral health promotion and disease prevention into their practices but can experience challenges integrating oral health services into their workflow. Most electronic health records (EHRs) in primary care settings do not include oral health information for pediatric patients. Therefore, it is important to understand providers' preferences for oral health information within the EHR. The objectives of this study are to assess (1) the relative importance of various elements of pediatric oral health information for primary care providers to have in the EHR and (2) the extent to which practice and provider characteristics are associated with these information preferences. METHODS: We surveyed a sample of primary care physicians who conducted Medicaid well-child visits in North Carolina from August - December 2013. Using descriptive statistics, we analyzed primary care physicians' oral health information preferences relative to their information preferences for traditional preventive aspects of well-child visits. Furthermore, we analyzed associations between oral health information preferences and provider- and practice-level characteristics using an ordinary least squares regression model. RESULTS: Fewer primary care providers reported that pediatric oral health information is "very important," as compared to more traditional elements of primary care information, such as tracking immunizations. However, the majority of respondents reported some elements of oral health information as being very important. Also, we found positive associations between the percentage of well child visits in which oral health screenings and oral health referrals are performed and the reported importance of having pediatric oral health information in the EHR. CONCLUSIONS: Incorporating oral health information into the EHR may be desirable for providers, particularly those who perform oral health screenings and dental referrals.

Science, Politics, and Communication: The Case of Community Water Fluoridation in the US.

Community water fluoridation (CWF) and its effect in reducing the burden of dental caries (tooth decay) is considered one of the 10 public health achievements in the 20th century. In the U.S., three-quarters (74.4%) of people on community water supplies have optimally fluoridated water, and each year approximately 90 communities actively consider starting or discontinuing CWF. CWF exists within the policy environment and includes actions taken by local community councils, health and water boards, and groups; state legislatures and health departments; national regulatory and science agencies; independent science entities; and professional and nonprofit organizations. Epidemiologists have been in the forefront of CWF. Experience with the past 70 years reveals that the coming decades will bring additional questions, recommendations, and challenges for CWF. The continued involvement of epidemiologists as part of multidisciplinary teams is needed in research, surveillance, peer review of studies, assessment of systematic review findings, and in the translation and communication of science findings to audiences with limited science/health literacy. This chapter's purpose is to 1) examine how epidemiologic evidence regarding CWF has been translated into practice and policy, 2) examine how recommendations for and challenges to CWF have affected epidemiologic research and community decision-making, and 3) identify lessons learned for epidemiologists.

Perspectives on Innovations in Oral Health Care.

A downward trend in dental caries in permanent teeth of children that began in the 1970s has leveled out at historic lows. Severe periodontal disease affects a small percentage of people, and tooth loss has plummeted so that complete tooth loss, once a common occurrence, now is almost non-existent in upper socioeconomic groups. But not all people have benefited equally from these positive trends. Dental problems continue to affect the disadvantaged in society at unacceptable rates, and their disease burden is likely to increase because of trends in social determinants of oral diseases.Personal dental care alone usually is unable to provide a sufficient buffer against these risks to maintain adequate oral health. Extensive disease in young children too often requires treatment in the hospital with a high chance of relapse. A national health goal is to "achieve health equity, eliminate disparities, and improve the health of all groups." Achieving this goal in oral health requires that things be done differently.This issue of the North Carolina Medical Journal highlights several approaches being tried here in North Carolina and elsewhere to address oral health problems. Initiatives fall into 4 categories: advocacy, workforce policies, integration of oral health and primary care, and the medical management of caries.

Trends in Oral Diseases in the U.S. Population.

This article reviews trends in dental caries, periodontal disease, and tooth loss for the United States along with population dynamics and risk factors that might influence these trends going forward. Dental caries experience remains high in the primary dentition. Caries severity in permanent teeth of children has declined to historically low levels, and long-standing inequalities in untreated caries appear to be narrowing. Declines in caries severity of children's permanent teeth have stabilized at a low level, but likely will contribute to future reductions in dental caries severity in adults. The prevalence of periodontal disease is high in adults, and only a small percentage have severe forms of the disease. Countervailing trends in determinants would suggest little change in the prevalence of periodontal disease in the future, but the lack of an obvious trend over the last two decades makes projections uncertain. Tooth loss as a consequence of dental disease has declined markedly over the last half century and has been all but eliminated in high-income groups. However, notable exceptions to these favorable trends are evident. Progress in prevention policies and programs that affect disease experience appears slower than progress in meeting population-level caries treatment needs. Clearly, long-standing inequities related to political and social determinants remain for all dental diseases, and income disparities in dental disease are widening for some indicators. Growing inequalities raise ethical and public health concerns that should be prominent in discussions of dental workforce needs and strategies for the next 25 years. This article was written as part of the project "Advancing Dental Education in the 21st Century."

Enrollment in early head start and oral health-related quality of life.

PURPOSE: Dental problems in young children are widespread and can negatively impact quality of life. We examined the effect of enrollment in North Carolina Early Head Start (EHS)-a federally funded early education program for children under three years of age and their families-on oral health-related quality of life (OHRQoL). METHODS: In this quasi-experimental study, we interviewed 479 EHS and 699 Medicaid matched parent-child dyads at baseline (children's average age 10 months) and 24 months later. Parents reported OHRQoL using the Early Childhood Oral Health Impact Scale (ECOHIS), a 0-52 point scale with higher scores representing more negative impacts. We used a marginalized semicontinuous two-part model to estimate: (1) the effect of EHS on the probability of reporting any follow-up impacts (ECOHIS ≥ 1), and (2) the difference in overall mean ECOHIS follow-up scores. We controlled for baseline ECOHIS, language, and EHS and non-EHS group imbalances using a propensity score. RESULTS: At follow-up, negative OHRQoL impacts were more often reported by parents of non-EHS than EHS children (45 versus 37%, P < .01). In the adjusted model, EHS parents reported a lower odds of negative OHRQoL impacts (OR 0.70; 95% CI 0.52, 0.94). Mean adjusted ECOHIS scores were not significantly different (EHS: 1.59 ± 3.34 versus non-EHS: 2.11 ± 3.85, P > 0.05). CONCLUSIONS: This study is the first to demonstrate that families of young children enrolled in EHS report improved OHRQoL compared to their non-enrolled peers. These results highlight the potential effectiveness of improving the quality of life of low-resource families through early childhood education.

Impact of Early Head Start in North Carolina on Dental Care Use Among Children Younger Than 3 Years.

OBJECTIVES: To examine the effects of North Carolina Early Head Start (EHS), an early education program for low-income children younger than 3 years and their families, on dental care use among children. METHODS: We performed a quasi-experimental study in which we interviewed 479 EHS and 699 non-EHS parent-child dyads at baseline (2010-2012) and at a 24-month follow-up (2012-2014). We estimated the effects of EHS participation on the probability of having a dental care visit after controlling for baseline dental care need and use and a propensity score covariate; we included random effects to account for EHS program clustering. RESULTS: The odds of having a dental care visit of any type (adjusted odds ratio [OR] = 2.5; 95% confidence interval [CI] = 1.74, 3.48) and having a preventive dental visit (adjusted OR = 2.6; 95% CI = 1.84, 3.63) were higher among EHS children than among non-EHS children. In addition, the adjusted mean number of dental care visits among EHS children was 1.3 times (95% CI = 1.17, 1.55) the mean number among non-EHS children. CONCLUSIONS: This study is the first, to our knowledge, to demonstrate that EHS participation increases dental care use among disadvantaged young children.

Training Requirements and Curriculum Content for Primary Care Providers Delivering Preventive Oral Health Services to Children Enrolled in Medicaid.

BACKGROUND AND OBJECTIVES: Despite the emphasis on delivery of preventive oral health services in non-dental settings, limited information exists about state Medicaid policies and strategies to educate practicing physicians in the delivery of these services. This study aims to determine: (1) training requirements and policies for reimbursement of oral health services, (2) teaching delivery methods used to train physicians, and (3) curricula content available to providers among states that reimburse non-dental providers for oral health services. METHODS: Using Web-based Internet searches as the primary data source, and a supplemental e-mail survey of all states offering in-person training, we assessed training requirements, methods of delivery for training, and curriculum content for states with Medicaid reimbursement to primary care providers delivering preventive oral health services. RESULTS of descriptive analyses are presented for information collected and updated in 2014. RESULTS: Forty-two states provide training sessions or resources to providers, 34 requiring provider training before reimbursement for oral health services. Web-based training is the most common CME delivery method. Only small differences in curricular content were reported by the 11 states that use in-person didactic sessions as the delivery method. CONCLUSIONS: Although we found that most states require training and curricular content is similar, training was most often delivered using Web-based courses without any additional delivery methods. Research is needed to evaluate the impact of a mixture of training methods and other quality improvement methods on increased adoption and implementation of preventive oral health services in medical practices.

Influences on preschool children's oral health-related quality of life as reported by English and Spanish-speaking parents and caregivers.

OBJECTIVE: This study examined young, preschool children's oral health-related quality of life (OHRQoL) among a community-based cohort of English and Spanish-speaking parent-child dyads in North Carolina, and sought to quantify the association of parent/caregiver characteristics, including spoken language, with OHRQoL impacts. METHODS: Data from structured interviews with 1,111 parents of children aged 6-23 months enrolled in the Zero-Out Early Childhood Caries study in 2010-2012 were used. OHRQoL was measured using the overall score (range: 0-52) of the Early Childhood Oral Health Impact Scale (ECOHIS). We examined associations with parents' sociodemographic characteristics, spoken language, self-reported oral and general health, oral health knowledge, children's dental attendance, and dental care needs. Analyses included descriptive, bivariate, and multivariate methods based upon zero-inflated negative binomial regression. To determine differences between English and Spanish speakers, language-stratified model estimates were contrasted using homogeneity χ2 tests. RESULTS: The mean overall ECOHIS score was 3.9 [95% confidence interval (CI) = 3.6-4.2]; 4.7 among English-speakers and 1.5 among Spanish speakers. In multivariate analyses, caregivers' education showed a positive association with OHRQoL impacts among Spanish speakers [prevalence ratio (PR) = 1.12 (95% CI = 1.03-1.22), for every added year of schooling], whereas caregivers' fair/poor oral health showed a positive association among English speakers (PR = 1.20; 95% CI = 1.02-1.41). CONCLUSIONS: The overall severity of ECOHIS impacts was low among this population-based sample of young, preschool children, and substantially lower among Spanish versus English speakers. Further studies are warranted to identify sources of these differences in - actual or reported - OHRQoL impacts.

Provision of Preventive Dental Services in Children Enrolled in Medicaid by Nondental Providers.

OBJECTIVES: Aims of this study are to determine (1) the association of oral health services (OHS) provided by nontraditional providers with the percentage of Medicaid children 0 to 5 years of age who receive ≥1 preventive services from all provider types in the United States; and (2) characteristics of state Medicaid policies associated with provision of OHS. METHODS: We conducted a time-series cross-sectional study of preventive services provided by nontraditional (OHS) and dental (PDS) providers for Medicaid-enrolled children from birth to 5 years of age in all states during 2010 to 2013 (204 observations). We applied panel data multiple regression analysis techniques to exploit year and state variation in aggregate data available in Centers for Medicare and Medicaid Services reports (form CMS-416). Total preventive dental services (TPDS =OHS + PDS) was predicted by months since state enactment of a policy to reimburse medical providers for OHS. RESULTS: The 44 states with a policy reported 4.3% of children per state per year with any OHS. For all states, an average of 30.1% received PDS and 34.5% TPDS. The delivery of OHS was associated with a small increase in percentage with TPDS. One year of Medicaid OHS availability was associated with an increase of 1.5% in the percentage of children with TPDS per state per year. CONCLUSIONS: Implementation of policies by Medicaid programs to support integration of OHS into primary care is associated with increases in overallTPDS use, but efforts are needed to improve implementation in practice to achieve national impact on access.

Propensity score weighting: an application to an Early Head Start dental study.

OBJECTIVES: Nonrandomized group assignment in intervention studies can lead to imbalances in preintervention covariates and biased effect estimates. We use propensity score estimation to account for such imbalances in an Early Head Start (EHS) dataset with rich pretreatment information. We compare propensity score results using standard logistic regression models (LRMs) versus generalized boosted models (GBMs). METHODS: We estimated propensity scores using 47 socio-demographic characteristics and EHS enrollment criteria obtained by parent interviews from a state-wide sample of 637 EHS and 930 Medicaid-matched control children. LRMs and GBMs were used to estimate propensity scores related to EHS enrollment. Performance of both approaches was evaluated via a) measures of balance of pretreatment covariate distributions between treated and control subjects, and b) stability of propensity score weights measured by the effective sample size. RESULTS: Distributions of all variables were balanced for EHS and non-EHS groups using propensity score weights calculated with LRM and GBM. Compared with LRM, GBM resulted in better balance between treated and propensity score-weighted control distributions. The effective sample size of the controls decreased from 930 subjects to 507 with GBM and to 335 with LRM. CONCLUSION: Although propensity scores derived from GBM and LRM both effectively balanced observed preintervention covariates, GBM resulted in better covariate balance compared with LRM. GBM also resulted in a larger effective sample size of the control group compared with LRM. Propensity score weighting using GBM is an effective statistical method to reduce confounding due to imbalanced distributions of measured preintervention covariates in this EHS intervention study.

Dental Caries: Racial and Ethnic Disparities Among North Carolina Kindergarten Students.

OBJECTIVES: We examined racial/ethnic disparities in dental caries among kindergarten students in North Carolina and the cross-level effects between students' race/ethnicity and school poverty status. METHODS: We adjusted the analysis of oral health surveillance information (2009-2010) for individual-, school-, and county-level variables. We included a cross-level interaction of student's race/ethnicity (White, Black, Hispanic) and school National School Lunch Program (NSLP) participation (< 75% vs ≥ 75% of students), which we used as a compositional school-level variable measuring poverty among families of enrolled students. RESULTS: Among 70,089 students in 1067 schools in 95 counties, the prevalence of dental caries was 30.4% for White, 39.0% for Black, and 51.7% for Hispanic students. The adjusted difference in caries experience between Black and White students was significantly greater in schools with NSLP participation of less than 75%. CONCLUSIONS: Racial/ethnic oral health disparities exist among kindergarten students in North Carolina as a whole and regardless of school's poverty status. Furthermore, disparities between White and Black students are larger in nonpoor schools than in poor schools. Further studies are needed to explore causal pathways that might lead to these disparities.

Effects of Physician-Based Preventive Oral Health Services on Dental Caries.

BACKGROUND: Most Medicaid programs reimburse nondental providers for preventive dental services. We estimate the impact of comprehensive preventive oral health services (POHS) on dental caries among kindergarten students, hypothesizing improved oral health among students with medical visits with POHS. METHODS: We conducted a retrospective study in 29,173 kindergarten students by linking Medicaid claims (1999-2006) with public health surveillance data (2005-2006). Zero-inflated regression models estimated the association between number of visits with POHS and (1) decayed, missing, and filled primary teeth (dmft) and (2) untreated decayed teeth while adjusting for confounding. RESULTS: Kindergarten students with ≥4 POHS visits averaged an adjusted 1.82 dmft (95% confidence interval: 1.55 to 2.09), which was significantly less than students with 0 visits (2.21 dmft; 95% confidence interval: 2.16 to 2.25). The mean number of untreated decayed teeth was not reduced for students with ≥4 POHS visits compared with those with 0 visits. CONCLUSIONS: POHS provided by nondental providers in medical settings were associated with a reduction in caries experience in young children but were not associated with improvement in subsequent use of treatment services in dental settings. Efforts to promote oral health in medical settings should continue. Strategies to promote physician-dentist collaborations are needed to improve continuity of care for children receiving dental services in medical settings.
