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.

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.

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.

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.

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.

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.

Examining continuity of care for Medicaid-enrolled children receiving oral health services in medical offices.

Children living in poverty encounter barriers to dentist visits and disproportionally experience dental caries. To improve access, most state Medicaid programs reimburse pediatric primary care providers for delivering preventive oral health services. To understand continuity of oral health services for children utilizing the North Carolina (NC) Into the Mouths of Babes (IMB) preventive oral health program, we examined the time to a dentist visit after a child's third birthday. This retrospective cohort study used NC Medicaid claims from 2000 to 2006 for 95,578 Medicaid-enrolled children who received oral health services before age 3. We compared children having only dentist visits before age 3 to those with: (1) only IMB visits and (2) both IMB and dentist visits. Cox proportional hazards regression was used to estimate the time to a dentist visit following a child's third birthday. Propensity scores with inverse-probability-of-treatment-weights were used to address confounding. Children with only IMB visits compared to only dentist visits before age 3 had lower rates of dentist visits after their third birthday [adjusted hazard ratio (AHR) = 0.41, 95 % confidence interval (CI) 0.39-0.43]. No difference was observed for children having both IMB and dentist visits and only dentist visits (AHR = 0.99, 95 % CI 0.96-1.03). Barriers to dental care remain as children age, hindering continuity of care for children receiving oral health services in medical offices.

Effects of early dental office visits on dental caries experience.

OBJECTIVES: We determined the association between timing of a first dentist office visit before age 5 years and dental disease in kindergarten. METHODS: We used North Carolina Medicaid claims (1999-2006) linked to state oral health surveillance data to compare caries experience for kindergarten students (2005-2006) who had a visit before age 60 months (n=11,394) to derive overall exposure effects from a zero-inflated negative binomial regression model. We repeated the analysis separately for children who had preventive and tertiary visits. RESULTS: Children who had a visit at age 37 to 48 and 49 to 60 months had significantly less disease than children with a visit by age 24 months (incidence rate ratio [IRR]=0.88; 95% confidence interval [CI]=0.81, 0.95; IRR=0.75; 95% CI=0.69, 0.82, respectively). Disease status did not differ between children who had a tertiary visit by age 24 months and other children. CONCLUSIONS: Medicaid-enrolled children in our study followed an urgent care type of utilization, and access to dental care was limited. Children at high risk for dental disease should be given priority for a preventive dental visit before age 3 years.

Comparing medical and dental providers of oral health services on early dental caries experience.

OBJECTIVES: Most state Medicaid programs reimburse nondental primary care providers (PCPs) for providing preventive oral health services to young children. We examined the association between who (PCP, dentist, or both) provides these services to Medicaid enrollees before age 3 years and oral health at age 5 years. METHODS: We linked North Carolina Medicaid claims (1999-2006) to oral health surveillance data (2005-2006). Regression models estimated oral health status (number of decayed, missing, and filled primary teeth) and untreated disease (proportion of untreated decayed teeth), with adjustment for relevant characteristics and by using inverse-probability-of-treatment weights to address confounding. RESULTS: We analyzed data for 5235 children with 2 or more oral health visits from a PCP, dentist, or both. Children with multiple PCP or dentist visits had a similar number of overall mean decayed, missing, and filled primary teeth in kindergarten, whereas children with only PCP visits had a higher proportion of untreated decayed teeth. CONCLUSIONS: The setting and provider type did not influence the effectiveness of preventive oral health services on children's overall oral health. However, children having only PCP visits may encounter barriers to obtaining dental treatment.

Care coordination among pediatricians and dentists: a cross-sectional study of opinions of North Carolina dentists.

BACKGROUND: Care coordination between physicians and dentists remains a challenge. This study of dentists providing pediatric dental care examined their opinions about physicians' role in oral health and identified factors associated with these opinions. METHODS: North Carolina general and pediatric dentists were surveyed on their opinions of how physicians should proceed after caries risk assessment and evaluation of an 18-month-old, low risk child. We estimated two multinomial logistic regression models to examine dentists' responses to the scenario under the circumstances of an adequate and a limited dental workforce. RESULTS: Among 376 dentists, 52% of dentists indicated physicians should immediately refer this child to a dental home with an adequate dental workforce. With a limited workforce, 34% recommended immediate referral. Regression analysis indicated that with an adequate workforce guideline awareness was associated with a significantly lower relative risk of dentists' recommending the child remain in the medical home than immediate referral. CONCLUSIONS: Dentists' opinions and professional guidelines on how physicians should promote early childhood oral health differ and warrant strategies to address such inconsistencies. Without consistent guidelines and their application, there is a missed opportunity to influence provider opinions to improve access to dental care.

Mother-perceived social capital and children's oral health and use of dental care in the United States.

OBJECTIVES: We examined the association between mother-perceived neighborhood social capital and oral health status and dental care use in US children. METHODS: We analyzed data for 67 388 children whose mothers participated in the 2007 National Survey of Children's Health. We measured mothers' perceived social capital with a 4-item social capital index (SCI) that captures reciprocal help, support, and trust in the neighborhood. Dependent variables were mother-perceived ratings of their child's oral health, unmet dental care needs, and lack of a previous-year preventive dental visit. We performed bivariate and multivariable logistic regression analyses for each outcome. RESULTS: After we controlled for potential confounders, children of mothers with high (SCI = 5-7) and lower levels (SCI ≥ 8) of social capital were 15% (P = .05) and about 40% (P ≤ .02), respectively, more likely to forgo preventive dental visits than were children of mothers with the highest social capital (SCI = 4). Mothers with the lowest SCI were 79% more likely to report unmet dental care needs for their children than were mothers with highest SCI (P = .01). CONCLUSIONS: A better understanding of social capital's effects on children's oral health risks may help address oral health disparities.

Adoption and implementation of policies to support preventive dentistry initiatives for physicians: a national survey of Medicaid programs.

OBJECTIVES: We determined the number of state Medicaid programs adopting initiatives to support preventive dental services provision by nondental health care professionals, their perceived attributes, and implementation barriers. METHODS: We used Qualtrics to conduct a cross-sectional survey in 2008 of Medicaid dental program managers to determine organizational stage of adoption classified according to the Transtheoretical Model of Behavior Change with 3-year follow-up. We assessed perceptions of the influence of 18 initiative attributes on the decision to adopt, drawn from Roger's diffusion of innovations theory. Stage and date of adoption are presented descriptively. Attributes and barriers were analyzed by stage of adoption by using analyses of variance or χ(2) statistics. RESULTS: By 2011, 42 states had adopted a policy. Only 9 states included a comprehensive set of preventive services, the most common being fluoride varnish. Adoption was affected by perceived initiative simplicity and its compatibility with other Medicaid programs. Administrative barriers were the most common among the 15 studied. CONCLUSIONS: State Medicaid policies to reimburse nondental providers for preventive dental services are becoming widespread. Interventions are needed to ensure oral health services delivery at the practice level.

The relationship of oral health literacy and self-efficacy with oral health status and dental neglect.

OBJECTIVES: We examined the associations of oral health literacy (OHL) with oral health status (OHS) and dental neglect (DN), and we explored whether self-efficacy mediated or modified these associations. METHODS: We used interview data collected from 1280 female clients of the Special Supplemental Nutrition Program for Women, Infants and Children from 2007 to 2009 as part of the Carolina Oral Health Literacy Project. We measured OHL with a validated word recognition test (REALD-30), and we measured OHS with the self-reported National Health and Nutrition Examination Survey item. Analyses used descriptive, bivariate, and multivariate methods. RESULTS: Less than one third of participants rated their OHS as very good or excellent. Higher OHL was associated with better OHS (for a 10-unit REALD increase: multivariate prevalence ratio = 1.29; 95% confidence interval = 1.08, 1.54). OHL was not correlated with DN, but self-efficacy showed a strong negative correlation with DN. Self-efficacy remained significantly associated with DN in a fully adjusted model that included OHL. CONCLUSIONS: Increased OHL was associated with better OHS but not with DN. Self-efficacy was a strong correlate of DN and may mediate the effects of literacy on OHS.

Pediatricians' assessments of caries risk and need for a dental evaluation in preschool aged children.

BACKGROUND: Risk-based prioritization of dental referrals during well-child visits might improve dental access for infants and toddlers. This study identifies pediatrician-assessed risk factors for early childhood caries (ECC) and their association with the need for a dentist's evaluation. METHODS: A priority oral health risk assessment and referral tool (PORRT) for children < 36 months was developed collaboratively by physicians and dentists and used by 10 pediatricians during well-child visits. PORRT documented behavioral, clinical, and child health risks for ECC. Pediatricians also assessed overall ECC risk on an 11-point scale and determined the need for a dental evaluation. Logistic regression models calculated the odds for evaluation need for each risk factor and according to a 3-level risk classification. RESULTS: In total 1,288 PORRT forms were completed; 6.8% of children were identified as needing a dentist evaluation. Behavioral risk factors were prevalent but not strong predictors of the need for an evaluation. The child's overall caries risk was the strongest predictor of the need for an evaluation. Cavitated (OR = 17.5; 95% CI = 8.08, 37.97) and non-cavitated (OR = 6.9; 95% CI = 4.47, 10.82) lesions were the strongest predictors when the caries risk scale was excluded from the analysis. Few patients (6.3%) were classified as high risk, but their probability of needing an evaluation was only 0.36. CONCLUSIONS: Low referral rates for children with disease and prior to disease onset but at elevated risk, indicate interventions are needed to help improve the dental referral rates of physicians.

Oral health in North Carolina: innovations, opportunities, and challenges.

Dental disease can have negative and lasting effects on overall health and quality of life. The Institute of Medicine of the National Academy of Sciences reported last year that close to 5 million children in the United States did not receive needed care in 2008 because of costs. Increasing use of dental care has been selected by the U.S. Department of Health and Human Services as one of a small number of national leading health indicators, designating it as a national priority. Innovative initiatives have been undertaken in North Carolina to promote oral health, and there have been improvements in the state. For example, both the use of dental services among children and their oral health status are improving. Yet persistent and difficult challenges remain, such as ensuring an adequate workforce for the future, improving oral health literacy, maintaining existing programs, and resolving disparities in oral health and lifetime access to preventive and treatment services for all North Carolinians. This issue brief reviews some oral health initiatives and their outcomes--with a focus on youth. Commentaries in the policy forum also focus on access to oral health care; assessing, educating, and building the dental workforce; new practice models and trends; insurance innovation; and patients with special needs.

Oral health content of early education and child care regulations and standards.

OBJECTIVE: Almost two out of every three US children younger than five receive child care from someone other than their parents. Health promotion in early education and child care (EECC) programs can improve the general health of children and families, but little is known about the role of these programs in oral health. We identified U.S. EECC program guidelines and assessed their oral health recommendations for infants and toddlers. METHODS: State licensing regulations were obtained from the National Resource Center for Health and Safety in Child Care's online database. Professional standards were identified through a search of PubMed, early childhood organizations' websites, and early childhood literature. All EECC guidelines were reviewed for key terms related to oral health promotion in children and summarized by domains. RESULTS: Thirty-six states include oral health in their licensing regulations, but recommendations are limited and most often address the storage of toothbrushes. Eleven sets of standards were identified, four of which make recommendations about oral health. Standards from the American Academy of Pediatrics/American Public Health Association (AAP/APHA) and the Office of Head Start (OHS) provide the most comprehensive oral health recommendations regarding screening and referral, classroom activities, and education. CONCLUSIONS: Detailed guidelines for oral health practices exist but they exhibit large variation in number and content. States can use the comprehensive standards from the AAP/APHA and OHS to inform and strengthen the oral health content of their licensing regulations. Research is needed to determine compliance with regulations and standards, and their effect on oral health.

Multiple imputation of dental caries data using a zero-inflated Poisson regression model.

UNLABELLED: Excess zeros exhibited by dental caries data require special attention when multiple imputation is applied to such data. OBJECTIVE: The objective of this study was to demonstrate a simple technique using a zero-inflated Poisson (ZIP) regression model, to perform multiple imputation for missing caries data. METHODS: The technique is demonstrated using data (n = 24,403) from a medical office-based preventive dental program in North Carolina, where 27.2 percent of children (n = 6,637) were missing information on physician-identified count of carious teeth. We first estimate a ZIP regression model using the nonmissing caries data (n = 17,766). The coefficients from the ZIP model are then used to predict the missing caries data. RESULTS: This technique results in imputed caries counts that are similar to the non-missing caries data in their distribution, especially with respect to the excess zeros in the nonmissing caries data. CONCLUSION: This technique can be easily applied to impute missing dental caries data.

Oral health activities of early head start teachers directed toward children and parents.

OBJECTIVES: This cross-sectional study examined Early Head Start (EHS) teachers' oral health program activities and their association with teacher and program characteristics. METHODS: Self-completed questionnaires were distributed to the staff in all EHS programs in North Carolina. Variables for dental health activities for parents (four items) and children (four items) were constructed as the sum of responses to a 0-4 Likert-type scale (never to very frequently). Ordinary least squares regression models examined the association between teachers' oral health program activities and modifiable teacher (oral health knowledge, values, self-efficacy, dental health training, perceived barriers to dental activities) and program (director and health coordinator knowledge and perceived barriers to dental activities) characteristics. RESULTS: Teachers in the parent (n=260) and child (n=231) analyses were a subset of the 485 staff respondents (98 percent response rate). Teachers engaged in child oral health activities (range = 0-16; mean = 9.0) more frequently than parent activities (range = 0-16; mean = 6.9). Teachers' oral health values, perceived oral health self-efficacy, dental training, and director and health coordinator knowledge were positively associated with oral health activities (P < 0.05). Perceived barriers were negatively associated with child activities (P < 0.05). CONCLUSION: The level of oral health activity in EHS programs is less than optimal. Several characteristics of EHS staff were identified that can be targeted with education interventions. Evidence for effectiveness of EHS interventions needs to be strengthened, but results of this survey provide encouraging findings about the potential effects of teacher training on their oral health practices.

Oral health literacy levels among a low-income WIC population.

OBJECTIVES: To determine oral health literacy (OHL) levels and explore potential racial differences in a low-income population. METHODS: This was a cross-sectional study of caregiver/child dyads that completed a structured 30-minute in-person interview conducted by two trained interviewers in seven counties in North Carolina. Sociodemographic, OHL, and dental health-related data were collected. OHL was measured with a dental word recognition test [Rapid Estimate of Adult Literacy in Dentistry (REALD-30)]. Descriptive, bivariate, and multivariate methods were used to examine the distribution of OHL and explore racial differences. RESULTS: Of 1658 eligible subjects, 1405 (85 percent) participated and completed the interviews. The analytic sample (N=1280) had mean age 26.5 (standard deviation = 6.9) years with 60 percent having a high school degree or less. OHL varied between racial groups as follows: Whites--mean score = 17.4 (SE = 0.2); African-American (AA)--mean score = 15.3 [standard error (SE) = 0.2]; American Indian (AI)--mean score = 13.7 (SE = 0.3). Multiple linear regression revealed that after controlling for education, county of residence, age, and Hispanic ethnicity, Whites had 2.0 points (95 percent CI = 1.4, 2.6) higher adjusted REALD-30 score versus AA and AI. CONCLUSIONS: Differences in OHL levels between racial groups persisted after adjusting for education and sociodemographic characteristics.

Holding up the oral health safety net: the role of National Health Service Corps alumni dentists in North Carolina.

BACKGROUND: Access to oral health care among low income populations is a growing problem. The National Health Service Corps (NHSC) might increase the supply of dentists motivated to provide services for this population. OBJECTIVE: To determine if North Carolina dentists who began a service obligation with the NHSC in 1990-1999 continued to provide care for underserved populations and if they differ from non-NHSC alumni primary care dentists who started practice in the state during that same period. METHODS: All 19 NHSC alumni and 50 comparison dentists were surveyed by mail. NHSC alumni also responded to selected items in a telephone follow-up interview. The two groups were compared using difference of means tests and multivariate contingency tables. RESULTS: National Health Service Corps alumni were more likely to be African-American (38%vs. 10%), work in safety net practices (84%vs. 23%), and see more publicly insured patients (60%vs. 19%) than comparison dentists. Yet their job satisfaction was comparable to non-NHSC alumni dentists. Analyses suggested that current practice in safety net settings is affected by dentists' race, altruistic motivations and previous NHSC participation. CONCLUSION AND POLICY IMPLICATION: Targeted recruitment of African-American dentists and others wanting to work in underserved communities could amplify the effectiveness of the financial incentive of NHSC loan repayment and induce dentists to remain in 'safety net' settings.
