Children's oral health-related behaviours and early childhood caries: A latent class analysis

OBJECTIVE

In this cross-sectional study in a large community-based sample of preschool-age children, we sought to identify distinct clusters of modifiable early childhood oral health-related behaviours (OHBs) and quantify their association with clinical and parent-reported measures of early childhood oral health.

METHODS

We relied upon a questionnaire (n = 8033; 11% in Spanish) and clinical oral health data (n = 6404; early childhood caries [ECC] prevalence = 54%] collected in the context of an epidemiologic study of early childhood oral health among 3- to 5-year-old children in North Carolina. Latent class analysis was used to identify clusters of modifiable OHBs based on parents' responses to 6 questionnaire items pertaining to their children's oral hygiene, diet and dental home. The optimal number of clusters was determined based on measures of model fit and interpretability. We examined associations of OHB clusters with clinical and parent-reported child oral health status (ie, ECC prevalence, severity and proportion with untreated disease) using bivariate association tests and multivariable regression modelling with marginal effects estimation accounting for clustered data. We used Mplus v.8.6 (Muthén & Muthén, Los Angeles, CA, USA) and Stata v.16.1 (StataCorp, College Station, TX, USA) for data analyses.

RESULTS

We identified 2 OHB clusters, a favourable (74%) and an unfavourable (26%) one. Children in the favourable OHB cluster had better oral hygiene practices (ie, tooth brushing frequency and fluoridated toothpaste use), lower consumption frequency of sugar-containing snacks and beverages, less frequent reports of night-time bottle-feeding history and a higher likelihood of a dental home. Children in the unfavourable cluster had significantly higher ECC prevalence (57% vs 53%), caries burden (mean dmfs = 9.3 vs 7.6), untreated disease (43% vs 33%) and worse parent-reported oral health status than the favourable cluster.

CONCLUSIONS

Our findings demonstrate the importance and utility of clustering common, modifiable ECC risk factors in population studies - health promotion efforts may centre on groups of people rather than individual behavioural risk factors.

A Cost Analysis of Three Pharmacologic Behavior Guidance Modalities in Pediatric Dentistry

Purpose: The aims of this study was to compare dental treatment costs for three pharmacologic behavior guidance modalities: (1) dental office-based moderate sedation (SED); (2) hospital-based general anesthesia (GA-H); and (3) dental office-based general anesthesia (GA-OFF). Methods: Data were collected for healthy two- to six-year-olds who had full-mouth rehabilitation using GA-H at the University of North Carolina Children's Hospital, Chapel Hill, N.C., USA. Patients served as their own controls to compare costs across the three modalities. Rendered treatments were quantified using relative value units (RVUs). Costs included opportunity costs and administrative data. We relied upon ordinary least squares analyses to examine the relationship between total costs and RVUs. Results: Of 200 consecutive hospital records, 65 met the inclusion criteria. The mean age was 4.4 years old (range equals two to six years old; 41 ASA I, 24 ASA II). Dental treatment using GA-H averaged 118 minutes (range equals 62 to 256 minutes), with a mean of 12 teeth (range equals six to 20) treated. GA-H costs were 4.1 times greater than GA-OFF costs (range equals 1.1 to 4.9), and 4.5 times greater than SED costs (range equals 0.9 to 7.1); GA-OFF costs were 1.1 times greater than SED costs (range equals 0.7 to 1.6). Conclusions: Treatment completed (measured in relative value units) was correlated highest with costs for dental office-based moderate sedation and least for hospital-based general anesthesia. If more than four SED appointments are needed, GA-OFF may provide cost-savings; however, at no point does GA-H offer cost-savings.

An Algorithm-Based Approach for Behavior and Disease Management in Children

Pharmacologic behavior management for dental treatment is an approach to provide invasive yet compassionate care for young children; it can facilitate the treatment of children who otherwise may not cooperate for traditional in-office care. Some recent highly publicized procedural sedation-related tragedies have drawn attention to risks associated with pharmacologic management. However, it remains widely accepted that, by adhering to proper guidelines, procedural sedation can assist in the provision of high-quality dental care while minimizing morbidity and mortality from the procedure. The purpose of this paper was to propose an algorithm for clinicians to consider when selecting a behavior and disease management strategy for early childhood caries. This algorithm will not ensure a positive outcome but can assist clinicians when counseling caregivers about risks, benefits, and alternatives. It also emphasizes and underscores best-safety practices.

A Contemporary Examination of First and Second Permanent Molar Emergence

The emergence of first permanent molars (FPMs) and second permanent molars (SPMs) is an important developmental milestone influencing caries risk and the timing of sealant placement. Emergence times have been shown to vary by sex and race/ethnicity, while recent reports suggest a positive association with adiposity. Amid the changing demographics of the US population and the rising rates of pediatric overweight/obesity, we sought to examine the association of body mass index (BMI) with FPM/SPM emergence in a representative sample of US children and adolescents. We used cross-sectional data from 3 consecutive cycles of the National Health and Nutrition Examination Survey (2009 to 2014). The FPM analysis included ages 4 to 8 y ( n = 3,102 representing ~20 million children), and the SPM analysis included ages 9 to 13 y ( n = 2,774 representing ~19 million children/adolescents). The Centers for Disease Control and Prevention's growth chart data were used to calculate age- and sex-specific BMI percentiles, as measures of adiposity. Initial data analyses relied on descriptive statistics and stratified analyses. We used multivariate methods, including survey linear and ordinal logistic regression and marginal effects estimation to quantify the association between pediatric overweight/obesity and FPM/SPM emergence, adjusting for age, sex, and race/ethnicity. Forty-eight percent of 6-y-olds and 98% of 8-y-olds had all FPMs emerged, whereas SPM emergence varied more. Blacks (vs. whites) and females (vs. males) experienced earlier emergence of FPMs and SPMs. Overweight/obesity was associated with earlier FPM emergence, particularly among black females. Obesity but not overweight was associated with earlier SPM emergence. Overall, overweight/obesity accounted for 6 to 12 mo of dental acceleration. This study's results emanate from the most recent US-representative data and affirm that FPM/SPM emergence varies by race/ethnicity and sex and is positively influenced by BMI. Future research should further elucidate these associations with detailed eruption data and examine the implications of this variation for clinical care.

The Impact of Non-nutritive Sucking on the Risk for Sleep-disordered Breathing in Children

PURPOSE

Sleep-disordered breathing (SDB) is not uncommon in children. The purposes of this study were to investigate the relationship between non-nutritive sucking (NNS) and the risk of SDB in children as well as assess the effect of infant feeding practices on SDB.

METHODS

Eighty-four healthy four- to 12-year-old children were categorized either as high or low risk for SDB based on the Pediatric Sleep Questionnaire (PSQ). NNS and feeding practices were determined using a customized caregiver questionnaire.

RESULTS

There was no statistically significant difference (P=0.21) between low- and high-risk children for a history of NNS. A statistically significant difference (P<0.001) was found for breastfed versus bottlefed children, with breastfeeding having a protective effect for SDB.

CONCLUSION

NNS had no effect on SDB, while breastfeeding reduced the risk substantially.

Addressing Selection Bias in Dental Health Services Research

When randomization is not possible, researchers must control for non-random assignment to experimental groups. One technique for statistical adjustment for non-random assignment is through the use of a two-stage analytical technique. The purpose of this study was to demonstrate the use of this technique to control for selection bias in examining the effects of the The Supplemental Program for Women, Infants, and Children’s (WIC) on dental visits. From 5 data sources, an analysis file was constructed for 49,512 children ages 1–5 years. The two-stage technique was used to control for selection bias in WIC participation, the potentially endogenous variable. Specification tests showed that WIC participation was not random and that selection bias was present. The effects of the WIC on dental use differed by 36% after adjustment for selection bias by means of the two-stage technique. This technique can be used to control for potential selection bias in dental research when randomization is not possible.

Is Dental Utilization Associated with Oral Health Literacy?

The objectives of this study were to examine the pattern of association between dental utilization and oral health literacy (OHL). As part of the Carolina Oral Health Literacy Project, clients in the Women, Infants, and Children's Special Supplemental Nutrition Program completed a structured 30-min in-person interview conducted by 2 trained interviewers at 9 sites in 7 counties in North Carolina. Data were collected on clients' OHL, sociodemographics, dental utilization, self-efficacy, and dental knowledge. The outcome, OHL, was measured with a dental word recognition test (30-item Rapid Estimate of Adult Literacy in Dentistry). Descriptive and multiple linear regression methods were used to examine the distribution of OHL and its association with covariates. After adjusting for age, education, race, marital status, self-efficacy, and dental knowledge, multiple linear regression showed that dental utilization was not a significant predictor of OHL (P > 0.05). Under the conditions of this study, dental utilization was not a significant predictor of OHL.

Caregivers' health literacy and gaps in children's Medicaid enrollment: findings from the Carolina Oral Health Literacy Study

Background and Objectives

Recent evidence supports a link between caregivers’ health literacy and their children’s health and use of health services. Disruptions in children’s health insurance coverage have been linked to poor health care and outcomes. We examined young children’s Medicaid enrollment patterns in a well-characterized cohort of child/caregivers dyads and investigated the association of caregivers’ low health literacy with the incidence of enrollment gaps.

Methods

We relied upon Medicaid enrollment data for 1208 children (mean age = 19 months) enrolled in the Carolina Oral Health Literacy project during 2008–09. The median follow-up was 25 months. Health literacy was measured using the Newest Vital Sign (NVS). Analyses relied on descriptive, bivariate, and multivariate methods based on Poisson modeling.

Findings

One-third of children experienced one or more enrollment gaps; most were short in duration (median = 5 months). The risk of gaps was inversely associated with caregivers’ age, with a 2% relative risk decrease for each added year. Low health literacy was associated with a modestly elevated risk increase [Incidence Rate Ratio (IRR) = 1.17 (95% confidence interval (CI) 0.88–1.57)] for enrollment disruptions; however, this estimate was substantially elevated among caregivers with less than a high school education [IRR = 1.52 (95% CI 0.99–2.35); homogeneity p<0.2].

Conclusions

Our findings provide initial support for a possible role of caregivers’ health literacy as a determinant of children’s Medicaid enrollment gaps. Although the association between health literacy and enrollment gaps was not confirmed statistically, we found that it was markedly stronger among caregivers with low educational attainment. This population, as well as young caregivers, may be the most vulnerable to the negative effects of low health literacy.

Dietary recommendations for infants and toddlers among pediatric dentists in North Carolina

PURPOSE

The purposes of this study were to: describe practice patterns, knowledge, and attitudes of pediatric dentists in North Carolina (N.C.) in delivering dietary recommendations to the parents/caregivers of infants and toddlers; and identify barriers that limit the implementation of related recommendations.

METHODS

Our survey instrument included 30 questions covering eight domains of barriers to guideline adherence. Surveys were mailed to 150 practicing pediatric dentists in N.C. Descriptive and bivariate analyses were performed. Exploratory factor analysis was used to identify subscales and inform the multivariable model.

RESULTS

The response rate was 57 percent (86/150), 80 percent of whom reported providing infant and toddler feeding recommendations routinely. Knowledge of and agreement with the recommendation regarding breast-feeding duration was lower than that for bottle-feeding recommendations. Stepwise logistic regression analysis indicated that survey respondents were less likely to provide dietary recommendations regularly to the parents/caregivers of infants and toddlers when they have practice constraints and the respondents disagree with American Academy of Pediatrics (AAP) and American Academy of Pediatric Dentistry (AAPD) recommendations on bottle and juice consumption.

CONCLUSIONS

Most respondents routinely provide dietary recommendations to the parents/caregivers of infants and toddlers. Disagreement with AAP and AAPD recommendations on bottle, and juice consumption as well as practice constraints impedes practitioners from providing dietary recommendations regularly to the parents/caregivers of infants and toddlers.

Influence of caregivers and children's entry into the dental care system

OBJECTIVES

Early preventive dental visits are essential in improving children's oral health, especially young children at high risk for dental caries. However, there is scant information on how these children enter the dental care system. Our objectives were as follows: (1) to describe how a population-based cohort of young Medicaid-enrolled children entered dental care; and (2) to investigate the influence of caregiver characteristics on their children's dental care-seeking patterns.

METHODS

We relied on Medicaid claims and interview data of caregiver-child dyads who were enrolled in the Carolina Oral Health Literacy study during 2007-2008. The analytical cohort comprised 1000 children who had no dental visits before enrollment. Additional information was collected on sociodemographic characteristics, oral health status, health literacy, dental neglect, and access to care barriers. Our analyses relied on descriptive, bivariate, and multivariate methods.

RESULTS

During the 25-month median follow-up period, 39% of the children (mean baseline age: 16 months) entered the dental care system, and 13% of their first encounters were for emergency care. Caregivers' dental neglect emerged as a significant predictor of nonentrance. Children with reported oral health problems at baseline were more likely to enter the dental care system compared with children with better oral health, but they were also more likely to require emergency care.

CONCLUSIONS

Caregivers have a pivotal role in children's oral health and care. Interventions aimed at improving children's oral health should involve community outreach to engage caregivers in a culturally appropriate manner when their children are infants or toddlers.

Caregivers' health literacy and their young children's oral-health-related expenditures

Caregivers' health literacy has emerged as an important determinant of young children's health care and outcomes. We examined the hypothesis that caregivers' health literacy influences children's oral-health-care-related expenditures. This was a prospective cohort study of 1,132 child/caregiver dyads (children's mean age = 19 months), participating in the Carolina Oral Health Literacy Project. Health literacy was measured by the REALD-30 (word recognition based) and NVS (comprehension based) instruments. Follow-up data included child Medicaid claims for CY2008-10. We quantified expenditures using annualized 2010 fee-adjusted Medicaid-paid dollars for oral-health-related visits involving preventive, restorative, and emergency care. We used descriptive, bivariate, and multivariate statistical methods based on generalized gamma models. Mean oral-health-related annual expenditures totaled $203: preventive--$81, restorative--$99, and emergency care--$22. Among children who received services, mean expenditures were: emergency hospital-based--$1282, preventive--$106, and restorative care--$343. Caregivers' low literacy in the oral health context was associated with a statistically non-significant increase in total expenditures (average annual difference = $40; 95% confidence interval, -32, 111). Nevertheless, with both instruments, emergency dental care expenditures were consistently elevated among children of low-literacy caregivers. These findings provide initial support for health literacy as an important determinant of the meaningful use and cost of oral health care.

A cross sectional study examining social desirability bias in caregiver reporting of children's oral health behaviors

Background

Our previous research (Pediatrics 2010:126) found a strong association between caregiver oral health literacy (OHL) and children’s oral health status; however, we found a weak association with oral health behaviors (OHBs). We hypothesize that this may be due to social desirability bias (SDB). Our objectives were to compare caregivers’ responses to traditional OHB items and newer SDB-modulating items, and to examine the association of caregiver literacy with OHBs.

Methods

We performed a cross-sectional study of 102 caregiver-child dyads, collecting data for OHBs using both traditional and new SDB-modulating items. We measured OHL using REALD-30, a validated word recognition test. We relied upon percent agreement and Cohen’s kappa (k) to quantify the concordance in caregivers’ responses and multivariate log-binomial regression to estimate the impact of OHL on OHBs.

Results

Caregivers’ mean REALD-30 score was 20.7 (SD = 6.0), range 1-30. We found an association between OHL and 4 of 8 OHBs examined. A subset of behavior questions compared traditional versus SDB-modulating items: history of bottle-feeding: agreement = 95%, k = 0.83 (95% CL:0.68,0.99); daily tooth brushing: agreement = 78%, k = 0.25 (95% CL:0.04,0.46); fluoridated toothpaste use: agreement = 88%, k = 0.67 (95% CL:0.49,0.85). After controlling for caregivers’ race, marital status and study site, higher literacy scores remained associated with a decreased prevalence of parental report of “decided not brush the child’s teeth because it would be frustrating”.

Conclusions

Agreement between responses was high for 2 of 3 behavior items. Item 3 (tooth brushing frequency) revealed discordance, likely due to SDB. Use of the SDB-modulating items appears to yield a better estimate of OHB.

The safety of sedation for overweight/obese children in the dental setting

PURPOSE

The goal of this study was to examine childhood overweight/obesity as a risk factor for adverse events during sedation for dental procedures.

METHODS

This was a cross-sectional, retrospective, IRB-approved study that included 17 years of data (1992-2009). The outcome variables were desaturation, nausea/vomiting, prolonged sedation, and true apnea. The major explanatory variables were weight percentiles and BMI percentiles.

RESULTS

A total of 510 patients met the inclusion criteria. Of these, 431 (86%) experienced no adverse events, 73 (14%) experienced one or more adverse events, and 6 had missing data. BMI data were available for a nested cohort of 103 children. Patients who experienced one or more adverse events had higher mean weights and BMI percentiles, though differences were not statistically significant. Another way to conceptualize the BMI data is to consider that 12% of the normal weight children experienced one or more adverse events versus 18% of the overweight/obese.

CONCLUSIONS

Overall, weight percentiles were higher in children who had one or more adverse events. Similarly, patients with higher BMI percentiles were more likely to experience adverse events. Although preliminary in nature, these findings suggest that childhood overweight/obesity may be associated with adverse events during sedation for dental procedures.

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.

Emerging therapies for the management of traumatized immature permanent incisors

Early loss of immature permanent teeth due to pulpal necrosis secondary to trauma can have dire consequences for a child's growth and development. The treatment alternatives include surgical endodontics, traditional calcium hydroxide apexification, and mineral trioxide aggregate (MTA) apexification. These options pose potential complications, including: arrest of root development; weakened dentinal walls; and increased potential for fracture. Revascularization of the dentin-pulp complex is a new approach that involves disinfecting the root canal system followed by tissue repair and regeneration while allowing for continued root development and thickening of the lateral dentinal walls through deposition of new hard tissue. The purpose of this report was to present the revascularization of an immature permanent maxillary central incisor that had evidence of external root resorption. Six months later, internal bleaching was performed to remove cervical discoloration from the triple antibiotic paste. At 18 months, the tooth remained vital and had evidence of continued root development.

The relationship of oral health literacy with oral health-related quality of life in a multi-racial sample of low-income female caregivers

Background

To investigate the association between oral health literacy (OHL) and oral health-related quality of life (OHRQoL) and explore the racial differences therein among a low-income community-based group of female WIC participants.

Methods

Participants (N = 1,405) enrolled in the Carolina Oral Health Literacy (COHL) study completed the short form of the Oral Health Impact Profile Index (OHIP-14, a measure of OHRQoL) and REALD-30 (a word recognition literacy test). Socio-demographic and self-reported dental attendance data were collected via structured interviews. Severity (cumulative OHIP-14 score) and extent of impact (number of items reported fairly/very often) scores were calculated as measures of OHRQoL. OHL was assessed by the cumulative REALD-30 score. The association of OHL with OHRQoL was examined using descriptive and visual methods, and was quantified using Spearman's rho and zero-inflated negative binomial modeling.

Results

The study group included a substantial number of African Americans (AA = 41%) and American Indians (AI = 20%). The sample majority had a high school education or less and a mean age of 26.6 years. One-third of the participants reported at least one oral health impact. The OHIP-14 mean severity and extent scores were 10.6 [95% confidence limits (CL) = 10.0, 11.2] and 1.35 (95% CL = 1.21, 1.50), respectively. OHL scores were distributed normally with mean (standard deviation, SD) REALD-30 of 15.8 (5.3). OHL was weakly associated with OHRQoL: prevalence rho = -0.14 (95% CL = -0.20, -0.08); extent rho = -0.14 (95% CL = -0.19, -0.09); severity rho = -0.10 (95% CL = -0.16, -0.05). "Low" OHL (defined as < 13 REALD-30 score) was associated with worse OHRQoL, with increases in the prevalence of OHIP-14 impacts ranging from 11% for severity to 34% for extent. The inverse association of OHL with OHIP-14 impacts persisted in multivariate analysis: Problem Rate Ratio (PRR) = 0.91 (95% CL = 0.86, 0.98) for one SD change in OHL. Stratification by race revealed effect-measure modification: Whites--PRR = 1.01 (95% CL = 0.91, 1.11); AA--PRR = 0.86 (95% CL = 0.77, 0.96).

Conclusions

Although the inverse association between OHL and OHRQoL across the entire sample was weak, subjects in the "low" OHL group reported significantly more OHRQoL impacts versus those with higher literacy. Our findings indicate that the association between OHL and OHRQoL may be modified by race.

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.

Impact of poor oral health on children's school attendance and performance

OBJECTIVES

We examined school days missed for routine dental care versus dental pain or infection to determine the relationship between children's oral health status and school attendance and performance.

METHODS

We used 2008 data from the North Carolina Child Health Assessment and Monitoring Program. The study sample, weighted to reflect the state's population, included 2183 schoolchildren. Variables assessed included school absences and performance, oral health status, parental education, health insurance coverage, race, and gender.

RESULTS

Children with poor oral health status were nearly 3 times more likely (odds ratio = 3.89; 95% confidence interval = 1.96, 7.75) than were their counterparts to miss school as a result of dental pain. Absences caused by pain were associated with poorer school performance (P < .05), but absences for routine care were not. Mediation analyses revealed that oral health status was associated with performance independent of absence for pain.

CONCLUSIONS

Children with poorer oral health status were more likely to experience dental pain, miss school, and perform poorly in school. These findings suggest that improving children's oral health status may be a vehicle to enhancing their educational experience.

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.

Oral health literacy among female caregivers: impact on oral health outcomes in early childhood

The aim of this study was to investigate the association of female caregivers' oral health literacy with their knowledge, behaviors, and the reported oral health status of their young children. Data on caregivers' literacy, knowledge, behaviors, and children's oral health status were used from structured interviews with 1158 caregiver/child dyads from a low-income population. Literacy was measured with REALD-30. Caregivers' and children's median ages were 25 yrs (range = 17-65) and 15 mos (range = 1-59), respectively. The mean literacy score was 15.8 (SD = 5.3; range = 1-30). Adjusted for age, education, and number of children, low literacy scores (< 13 REALD-30) were associated with decreased knowledge (OR = 1.86; 95% CI = 1.41, 2.45) and poorer reported oral health status (OR = 1.44; 95% CI = 1.02, 2.05). Lower caregiver literacy was associated with deleterious oral health behaviors, including nighttime bottle use and no daily brushing/cleaning. Caregiver oral health literacy has a multidimensional impact on reported oral health outcomes in infants and young children.

Addressing childhood overweight and obesity in the dental office: rationale and practical guidelines

The prevalence of childhood obesity has increased dramatically in the past 3 decades. The purposes of this paper were to: review health and dental implications; present guidelines for tracking body mass index (BMI) percentiles in children; and discuss reasonable "next steps" to take in communicating with parents and other health professionals. The health implications of childhood obesity warrant early monitoring, diagnosis, and treatment. Trends in visitation patterns of children offer dentists an unusual opportunity and an important role in addressing childhood obesity through regular monitoring of height, weight, and BMI percentiles. Dentists' collaborations with pediatricians, registered dietitians, and parents have the potential to address the detrimental physical and psychosocial effects of childhood obesity. We encourage dentists to determine height, weight, and BMI percentiles for their patients at least annually. They should refer patients with unhealthy weight trajectories to pediatricians or family physicians and consider ancillary referrals to registered dietitians.

Impact of caregiver literacy on children's oral health outcomes

OBJECTIVE

The objective of this study was to examine the relationship of primary caregivers' literacy with children's oral health outcomes.

METHODS

We performed a cross-sectional study of children who were aged < or =6 years and presented for an initial dental appointment in the teaching clinics at the University of North Carolina at Chapel Hill School of Dentistry. Caregiver literacy was measured using the Rapid Estimate of Adult Literacy in Dentistry (REALD-30). The outcome measures included oral health knowledge, oral health behaviors, primary caregiver's reports of their child's oral health status, and the clinical oral health status of the child as determined by a clinical examination completed by trained, calibrated examiners.

RESULTS

Among the 106 caregiver-child dyads enrolled, 59% of the children were male, 52% were white, and 86% of caregivers were the biological mothers. The bivariate results showed no significant relationships between literacy and oral health knowledge (P = .16) and behaviors (P = .24); however, there was an association between literacy and oral health status (P < .05). The multivariate analysis controlled for race and income; this analysis revealed a significant relationship between caregiver literacy scores and clinical oral health status as determined by using a standardized clinical examination. Caregivers of children with mild to moderate treatment needs were more likely to have higher REALD-30 scores than those with severe treatment needs (odds ratio: 1.14 [95% confidence interval: 1.05-1.25]; P = .003).

CONCLUSIONS

Caregiver literacy is significantly associated with children's dental disease status.

Correlation between laser fluorescence readings and volume of tooth preparation in incipient occlusal caries in vitro

OBJECTIVE

This study evaluated the correlation between laser fluorescence readings and the extent of incipient occlusal caries as measured by the volume of tooth preparation in vitro.

MATERIALS AND METHODS

One hundred and three permanent molars and premolars containing incipient occlusal pit-and-fissure caries and sound occlusal surfaces (1/4 of the sample, control) were selected. DIAGNOdent (KaVo Dental Corporation, Lake Zurich, IL, USA) readings were obtained according to manufacturer instructions. Caries was removed with 1/4 round burs in high speed. The volume of tooth preparation was measured using a surrogate measure based on the amount of composite needed to fill the preparations. Sensitivity and specificity using different cutoff values were calculated for lesions/preparations extending into dentin. The results were analyzed statistically.

RESULTS

The Pearson correlation for preparation volume and DIAGNOdent reading measurements was low (r = 0.285). Sensitivity and specificity of DIAGNOdent for detection of dentinal lesions were 0.83 and 0.60, and 0.66 and 0.73 for the cutoff values of 20 and 30, respectively.

CONCLUSIONS

Within the limitations of this study, laser fluorescence measured with DIAGNOdent does not correlate well with extent of carious tooth structure in incipient occlusal caries.

CLINICAL SIGNIFICANCE

Clinicians should not rely only on DIAGNOdent readings to determine the extension of incipient occlusal caries.

Factors affecting North Carolina dental hygienists' confidence in providing obesity education and counseling

PURPOSE

Obesity is a major public health issue in the United States. Dental hygienists influence their patients' oral health by providing dietary and behavioral recommendations that encourage good oral health practices. However, it is not known if they are ready to provide behavioral counseling strategies for weight loss. This study investigates whether dental hygienists in North Carolina are confident to counsel patients who are at-risk for obesity.

METHODS

A questionnaire was used to survey 246 dental hygienists attending a continuing education (CE) course. It investigated self-reported confidence in providing obesity counseling, educational preparation, outcome expectations and self-efficacy. The primary outcome was confidence in providing weight loss counseling. Mantel Haenszel statistics were used to compare group of interest.

RESULTS

Of the dental hygienists surveyed, 43% perceived an increase of overweight patients in their practices. Nearly all (95%) felt that dental hygienists have a role in helping patients improve nutrition. Over half (65%) expressed confidence in discussing obesity-related health risks. On average, the confidence in getting patients to follow weight loss advice was significantly different (p=0.02) for those with a 2 year degree and those with a 4 year degree.

CONCLUSIONS

The findings indicate that many North Carolina dental hygienists are willing to discuss obesity with patients.

Two case reports of complicated permanent crown fractures treated with partial pulpotomies

The partial pulpotomy can offer a superb outcome for the treatment of traumatic complicated crown fractures. The procedure is often used for dental trauma in children when the major aim of treatment is to preserve tooth vitality while providing a favorable environment for continued root development. The purpose of this paper was to review scientific evidence supporting partial pulpotomy and its high success rate and illustrate the clinical technique by presenting 2 challenging cases of complicated crown fractures with long-term follow-up.

Permanent tooth replantation following avulsion: using a decision tree to achieve the best outcome

An avulsion injury is a challenge to manage and there are many treatment options to consider to obtain the best prognosis depending on the avulsion scenario. In 2001, Lee et al published decision analysis paradigms for the management of avulsed permanent teeth to provide busy clinicians with user-friendly, referenced-based flowcharts to facilitate the best possible outcomes for managing these teeth in children and adolescents. The flowchart was updated in 2007 by McIntyre et al. The purpose of this paper is to update the 2001 and 2007 flowcharts and decision analyses with current concepts, recent literature-based findings, new treatment philosophies, and expert consensus from the 2008 AAPD Dental Trauma Symposium.

Nutritional counseling practices: how do North Carolina pediatric dentists weigh in?

It has been demonstrated that nutrition/healthy lifestyle counseling can help alleviate the childhood obesity crisis. Because pediatric dentists see children with regular frequency, they are uniquely positioned to help provide such counseling.

PURPOSE

To document current nutrition/healthy lifestyle counseling practices of pediatric dentists in NC and examine factors associated with those practices.

METHODS

A 65-item survey instrument was developed by an expert committee, pilot-tested and revised. The instrument contained questions in 6 domains: Academic Preparation, Knowledge, Confidence, Opinions, Practice Patterns and Barriers. It was sent to all clinically active pediatric dentists in NC.

RESULTS

The response rate was 69% (70/102). Less than 25% provided nutrition counseling services. Academic preparation in residency training was statistically significant (P<.05) in determining those who practiced nutritional counseling. Logistic regression revealed that respondents with higher overall knowledge (OR=18.2), those comfortable discussing weight-related issues (OR=47.7), those in practice >10 years (OR=20.6), and females (OR=173) were more likely to provide nutrition/healthy lifestyle counseling.

CONCLUSIONS

All respondents believed that childhood obesity is a major health concern and expressed a willingness to assist other health professionals in addressing this problem. These findings offer a rich source of data that can be used for educational initiatives and strategic planning.

Development and testing of the Test of Functional Health Literacy in Dentistry (TOFHLiD)

OBJECTIVE

This study aims to evaluate the reliability and validity of the Test of Functional Health Literacy in Dentistry (TOFHLiD), a new instrument to measure functional oral health literacy.

METHODS

TOFHLiD uses text passages and prompts related to fluoride use and access to care to assess reading comprehension and numerical ability. Parents of pediatric dental patients (n = 102) were administered TOFHLiD, a medical literacy comprehension test (TOFHLA), and two word recognition tests [Rapid Estimate of Adult Literacy in Dentistry (REALD), Rapid Estimate of Adult Literacy in Medicine (REALM)]. This design provided assessments of dental and medical health literacy by all subjects, both measured with two different methods (reading/numeracy ability and word recognition). Construct validity of TOFHLiD was assessed by entering the correlation coefficients for all pairwise comparisons of literacy instruments into a multitrait-multimethod matrix. Internal reliability of TOFHLiD was assessed with Cronbach's alpha. Criterion-related predictive validity was tested by associations between the TOFHLiD scores and the three measures of oral health in multivariate regression analyses.

RESULTS

The correlation coefficient for TOFHLiD and REALD-99 scores (monotrait-heteromethod) was high (r = 0.82, P < 0.05). Coefficients between TOFHLiD and TOFHLA (heterotrait-monomethod: r = 0.52) and REALM (heterotrait-heteromethod: r = 0.53) were smaller than coefficients for convergent validity Cronbach's alpha for TOFHLiD was 0.63. TOFHLiD was positively correlated with OHIP-14 (P < 0.05), but not with parent or child oral health. TOFHLA was not related to dental outcomes.

CONCLUSIONS

TOFHLiD demonstrates good convergent validity but only moderate ability to discriminate between dental and medical health literacy. Its predictive validity is only partially established, and internal consistency just meets the threshold for acceptability. Results provide solid support for more research, but not widespread use in clinical or public health practice.

Evaluation of a Word Recognition Instrument to Test Health Literacy in Dentistry: The REALD-99

OBJECTIVE

This study aims to evaluate a dental health literacy word recognition instrument.

METHODS

Based on a reading recognition test used in medicine, the Rapid Estimate of Adult Literacy in Medicine (REALM), we developed the Rapid Estimate of Adult Literacy in Dentistry (REALD-99). Parents of pediatric dental patients were recruited from local dental clinics and asked to read aloud words in both REALM and REALD-99. REALD-99 scores had a possible range of 0 (low literacy) to 99 (high literacy); REALM scores ranged from 0 to 66. Outcome measures included parents' perceived oral health for themselves and of their children, and oral health-related quality of life of the parent as measured by the short-form Oral Health Impact Profile (OHIP-14). To determine the validity, we tested bivariate correlations between REALM and REALD-99, REALM and perceived dental outcomes, and REALD-99 and perceived dental outcomes. We used ordinary least squares regression and logit models to further examine the relationship between REALD-99 and dental outcomes. We determined internal reliability using Cronbach's alpha.

RESULTS

One hundred two parents of children were interviewed. The average REALD-99 and REALM-66 scores were high (84 and 62, respectively). REALD-99 was positively correlated with REALM (PCC = 0.80). REALM was not related to dental outcomes. REALD-99 was associated with parents' OHIP-14 score in multivariate analysis. REALD-99 had good reliability (Cronbach's alpha = 0.86).

CONCLUSIONS

REALD-99 has promise for measuring dental health literacy because it demonstrated good reliability and is quick and easy to administer. Additional studies are needed to examine the validity of REALD-99 using objective clinical oral health measures and more proximal outcomes such as behavior and compliance to specific health instructions.

A prospective study of 2 sedation regimens in children: chloral hydrate, meperidine, and hydroxyzine versus midazolam, meperidine, and hydroxyzine

The aim of this study was to compare both the behavioral and physiological effects of 2 drug regimens in children: chloral hydrate (CH), meperidine (M), and hydroxyzine (H) (regimen A) versus midazolam (MZ), M, and H (regimen B). Patients between 24 and 54 months of age were examined by crossover study design. Behavior was analyzed objectively by the North Carolina Behavior Rating System and subjectively through an operator and monitor success scale. Physiological data were recorded every 5 minutes and at critical points throughout the appointment. Sixteen patients completed this study. No significant differences in behavior were noted by the North Carolina Behavior Rating System or the operator and monitor success scale. A quiet or annoyed behavior was observed 93% and 90% of the time for regimen A and regimen B, respectively. Using the operator and monitor success scale, 63% of regimen A and 56% of regimen B sedations were successful. No statistically significant differences were noted in any of the physiological parameters between the 2 regimens. Ten episodes of hemoglobin desaturation were detected with regimen A sedations. There were no differences between the sedative drug regimens CH/M/H and MZ/M/H for behavioral outcomes or physiological parameters.

Management of avulsed permanent incisors: a comprehensive update

An avulsion injury is a challenge to manage, and there are many factors to consider to obtain the best prognosis in each scenario. In 2001, Lee and colleagues published decision analysis paradigms for the management of avulsed permanent teeth for the purpose of providing busy clinicians with user-friendly, reference-based flow-charts to facilitate the best possible outcomes for managing these teeth in children and adolescents. The purpose of this article was to update the 2001 flow-charts and decision analyses with: (1) current concepts; (2) recent literature-based findings; and (3) new philosophies.

Effectiveness of an Educational Intervention in Oral Health for Pediatric Residents

OBJECTIVE

To evaluate the effectiveness of an oral health educational intervention designed to increase proficiency of pediatric residents in oral health.

METHODS

Pediatric residents at the University of North Carolina at Chapel Hill (UNC) participated in oral health education that included didactic sessions, hands-on instruction by pediatric dentists and residents, preventive dentistry prompts, and change strategies to introduce oral health into practice. Pediatric residents at East Carolina University (ECU), who had a short practicum in oral health, and Wake Forest University (WFU), who had no specific oral health instruction, served as comparison groups. All residents completed questionnaires before and 12 months after instruction began at UNC. Effects were tested for each school separately by repeated-measure analysis of variance.

RESULTS

The mean percentage of UNC residents who answered 18 knowledge questions correctly and reported frequently performing 10 preventive dental practices increased by 17.7% and 65.1%, respectively, from baseline levels. Residents' confidence in performing 10 counseling and oral health screening activities improved by 17.9%. Opinions about including oral health in their clinical care improved only slightly. Changes at ECU and WFU were small, but low response rates in those schools preclude substantive conclusions from between schools comparisons.

CONCLUSIONS

Multifaceted instruction in oral health was effective in improving pediatric residents' knowledge about oral health, their confidence in providing oral health services, and the delivery of these services in their ambulatory care practices. Residents also adopted the use of fluoride varnish, an innovation in pediatrics. More studies are needed to define the most efficient and effective residency-based instruction.

Examining the cost-effectiveness of early dental visits

The subject of early dental visits as an integral dimension of anticipatory guidance and the related supporting scientific evidence for this concept is a critical and timely issue for the dental profession. The purpose of this paper was to review the scientific evidence and rationale for early dental visits. In theory, early dental visits can prevent disease and reduce costs. During the age 1 dental visit, there is strong emphasis on prevention and parents are given: (1) counseling on infant oral hygiene; (2) home and office-based fluoride therapies; (3) dietary counseling; and (4) information relative to oral habits and dental injury prevention. There is evidence that the early preventive visits can reduce the need for restorative and emergency care, therefore reducing dentally related costs among high-risk children. Preschool Medicaid children who had an early preventive dental visit by age 1 were more likely to use subsequent preventive services and experienced less dentally related costs. These finding have significant policy implications, and more research is needed to examine this effect in a low-risk population.

Access to dental care for young children in North Carolina: history and current status of workforce issues

The 2000 North Carolina IOM report contained 23 recommendations. To date 16 have been fully or partially implemented. This represents progress, but accomplishing full compliance remains a goal. Absent new training programs in our state, as current federal training grants phase-out, identifying financial support to continue training an adequate number of pediatric dentists for North Carolina will be a challenge.

The childhood obesity epidemic: a role for pediatric dentists?

Since the 1970s, the incidence of obesity has more than doubled for children 2 to 5 years of age and adolescents 12 to 19 years of age, and has more than tripled for children 6 to 11 years of age. The increasing numbers of overweight and obese children and youth has led federal policymakers to rank it as a critical health threat. The purpose of this review article is to raise awareness within the pediatric dental community about the childhood obesity epidemic. This article reviews the underlying causes of childhood obesity and discusses the links between both nutrition and obesity to caries. Because pediatric health professionals have daily contact with children and their caregivers, the role of pediatric dentists in preventing and managing obesity is proposed and discussed. In addition, methods are presented that pediatric dentists can use to elevate awareness and address childhood overweight and obesity issues from practice-based, community-based, and advocacy/policy-based perspectives. The authors share an array of ideas that can be incorporated by the pediatric dental team in their practice and beyond.

Assessing cost-effectiveness of sealant placement in children

OBJECTIVE

The lack of cost-effectiveness information regarding sealant placement strategies is thought to have influenced reimbursement policies and subsequent sealant utilization in dental practice. This study compared three strategies for managing the occlusal surfaces of first permanent molars: seal all (SA), risk-based (RBS), and seal none (SN).

METHODS

A decision tree was developed for various possible outcomes following each of the above strategies. Due to the complexity of the decision tree, a Markov model was used to allow for the construction of a chain of events representing the natural history of sealant retention, caries formation, and their associated health states. The outcome measures were the incremental cost per month gained in a cavity-free state over a ten-year period.

RESULTS

Our theoretical model showed that RBS strategy improved clinical outcomes, in the form of cavity-free months, and saved money over SN. The strategy of sealing both high and low risk teeth (SA) further improved outcomes but at an additional cost compared to RBS. However, the cost was small, .08 dollars for each additional cavity-free month gained per tooth. Further, minor changes in the baseline assumptions resulted in the SA strategy being the dominant strategy.

CONCLUSION

This study provides evidence that sealing children's first permanent molars can improve outcomes and save money by delaying or avoiding invasive treatment and the destructive cycle of caries. In a time of limited funds for dental services, these results can assist payers in establishing more rational sealant reimbursement policies.

Early preventive dental visits: effects on subsequent utilization and costs

OBJECTIVE

To determine the effects of early preventive dental visits on subsequent utilization and costs of dental services among preschool-aged children.

DESIGN

This investigation studied North Carolina children who were enrolled continuously in Medicaid from birth for a 5-year period. Our research design was a longitudinal cohort study that relied on 4 large administrative datasets, including North Carolina composite birth records from 1992, Medicaid enrollment and claims files from 1992 to 1997, and the Area Resource File. Our outcome measures included type of use and dentally related costs.

RESULTS

Of the 53591 Medicaid-enrolled children born in 1992, 9204 were continuously enrolled for 5 years and met our inclusion criteria. Twenty-three children had their first preventive dental visit before 1 year of age, 249 between 1 and 2 years, 465 between 2 and 3 years, 915 between 3 and 4 years, and 823 between 4 and 5 years. Children who had their first preventive dental visit by age 1 were more likely to have subsequent preventive visits but were not more likely to have subsequent restorative or emergency visits. Those who had their first preventive visit at age 2 or 3 were more likely to have subsequent preventive, restorative, and emergency visits. The age at the first preventive dental visit had a significant positive effect on dentally related expenditures, with the average dentally related costs being less for children who received earlier preventive care. The average dentally related costs per child according to age at the first preventive visit were as follows: before age 1, 262 dollars; age 1 to 2, 339 dollars; age 2 to 3, 449 dollars; age 3 to 4, 492 dollars; age 4 to 5, 546 dollars.

CONCLUSIONS

Our results should be interpreted cautiously, because of the potential for selection bias; however, we concluded that preschool-aged, Medicaid-enrolled children who had an early preventive dental visit were more likely to use subsequent preventive services and experience lower dentally related costs. In addition, children from racial minority groups had significantly more difficulty in finding access to dental care, as did those in counties with fewer dentists per population.

The effects of the Women, Infants, and Children's Supplemental Food Program on dentally related Medicaid expenditures

OBJECTIVE

This study estimates the effects of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on dentally related Medicaid expenditures for young children.

METHODS

We used a five-year cohort study design to compare dentally related Medicaid expenditures for children enrolled in WIC versus those not enrolled for each year of life up to age 5 years. There were 49,795 children born in North Carolina in 1992 who met the inclusion criteria for the study. Their birth records were linked to Medicaid enrollment and claims files, WIC master files, and the Area Resource File. Our analysis strategy included a logit and OLS two-part model with CPI dollar adjustments.

RESULTS

Children who participated in WIC at ages 1 and 2 years had significantly less dentally related expenditures than those who did not participate. WIC participation at age 3 years did not have a significant effect. Fewer WIC children received dental care under general anesthesia than non-WIC children.

CONCLUSIONS

The WIC program has the potential for decreasing dentally related costs to the Medicaid program, while increasing use of dental services.

Effects of WIC participation on children's use of oral health services

OBJECTIVES

We estimated the effects of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on dental services use by Medicaid children in North Carolina.

METHODS

We used linked Medicaid claims and enrollment files, WIC files, and the area resource file to compare dental services use for children enrolled in WIC with those not enrolled. We used multivariate models that controlled for child clustering and employed 2-step methodology to control for selection bias.

RESULTS

Children who participated in WIC had an increased probability of having a dental visit, were more likely to use preventive and restorative services, and were less likely to use emergency services.

CONCLUSIONS

Children's WIC participation improved access to dental care services that should lead to improved oral health.

Parental evaluation of quality of life measures following pediatric dental treatment using general anesthesia

The purpose of this study was to examine (a) parental satisfaction with the dental care their child received under general anesthesia, and (b) perception of the impact of this care on physical and social quality of life. The sample included 45 children (median age 50 months, 26 boys and 19 girls). Data were collected using a 1-page survey instrument completed by the parent at the first follow-up appointment. Dichotomous dependent variables were developed to measure parental satisfaction, dental outcome, and social impact of treatment. There was an overwhelmingly positive impression with dental outcomes (pain relief and improved masticatory efficiency). Parental perceptions in the social dimension were also positive. Parents reported more smiling, improved school performance, and increased social interaction. Relative to overall health, the majority of parents reported an improvement. Logit regression analysis revealed that absence of pain (P < .05) and increased social interaction (P < .01) had a significant impact on parents' perception of overall health. Our findings indicate that dental care under general anesthesia for preschool children has a high degree of acceptance by parents and is perceived to have a positive social impact on their child.

Accuracy of pediatric primary care providers' screening and referral for early childhood caries

PURPOSE

Tooth decay is one of the more common diseases of childhood. Slightly >40% of US children are already affected by the time they reach kindergarten. Primary care physicians can play an important role in prevention and control of this disease because of their ready access to this population. Unlike dentists, they see a large percentage of children during their infant and toddler years. However, few studies have been conducted on oral screenings and referrals by primary care physicians or the effectiveness of their oral health preventive activities. The purpose of this study was to determine the accuracy of pediatric primary care providers' screening and referral for Early Childhood Caries.

METHODS

We sought to compare independent, blinded oral screening results and referral recommendations made by primary care providers with those of a pediatric dentist, considered for purposes of the study to be the reference gold standard. The study was conducted at a private pediatric group practice in North Carolina. The practice was selected because it serves a large volume of Medicaid patients and includes a large number of pediatric primary care providers (11 pediatricians and 1 nurse practitioner). Study participants included Medicaid-eligible children younger than 36 months of age with erupted teeth. The pediatric primary care providers in this practice received 2 hours of training in infant oral health. The training consisted of a review of the study methods and clinical slides illustrating dental caries in various stages of progression. Specific instructions were given to the providers on how to recognize a cavitated carious lesion and how to determine when a dental referral is needed. Providers were instructed to refer any child with 1 or more cavitated carious lesions, soft tissue pathology, or evidence of trauma to the teeth or mouth. Before commencing the study, calibration and a comparative analysis were performed to establish reliability and validity of the examinations performed by the pediatric dentist. Both a pediatric dentist and a pediatric primary care provider conducted a dental screening on each child and recorded carious teeth and whether a dental referral was needed. Sensitivity and specificity were calculated to compare the pediatric primary care providers' screenings to the gold standard (pediatric dentist) in 3 categories: caries at the tooth level, caries at the patient level (1 or more affected teeth), and need for referral.

RESULTS

The final study sample consisted of 258 preschool-aged children (122 males and 136 females) with a mean age of 21.2 months (standard deviation [SD]: 9.13). One hundred eighty-four (71.3%) of the participants were white, 58 (22.5%) were black, and 16 (6.2%) were Hispanic. Tooth-Level Analysis: The pediatric dentist reported an average of 0.30 (SD: 0.005) cavitated teeth per child, whereas the pediatric primary care providers reported a mean of 0.25 (SD: 0.004). This difference was not statistically significant (t test). The pediatric dentist identified 80 (2.4%) teeth with cavitated carious lesions, whereas the pediatric primary care providers identified 64 (1.9%), 25 of which were false-positives. Their screening results include 41 false-negative teeth. Thus, the primary care providers tended to under-count the number of teeth with carious lesions. They achieved a sensitivity of 0.49 (95% confidence interval [CI]: 0.47-0.51) and a specificity of 0.99 (95% CI: 0.99-1.0) when their screening results for individual teeth were compared with the gold standard. Patient-Level Analysis: At the patient level, the pediatric dentist identified 25 (9.7%) children with 1 or more teeth affected by cavitated lesions. The pediatric primary care providers collectively identified 30 (11.6%) children who had cavitated lesions. They achieved a sensitivity of 0.76 (95% CI: 0.71-0.81) and a specificity of 0.95 (95% CI: 0.93-0.98) in identifying those children with cavitated carious lesions. There were 6 false-negatives and 11 false-positives when the pediatric primary care providers' findings were compared with the gold standard. At the patient-level, the positive predictive value of the dental screening was 0.63 and the negative predictive value was 0.97. Dental Referral: The pediatric dentist referred a total of 27 (10.5%) children to a dentist. Two of these children were referred for trauma and the other 25 were referred for cavities. The pediatric primary care providers referred a total of 23 (8.9%) children to a dentist. Two referrals were made because the provider was concerned about stains on the teeth, whereas the remaining 21 were referred for cavities. The pediatric primary care providers achieved a sensitivity of 0.63 (95% CI: 0.57-0.69) and a specificity of 0.98 (95% CI: 0.96-0.99) when their recommendations for referral were compared with the gold standard. The number of children receiving a referral from a pediatric primary care provider for cavities (N = 21) was less than the number of children they identified as having cavities (N = 30). The providers as a whole tended to under-refer, and only 70% of children with evidence of dental disease received a referral.

CONCLUSIONS

After 2 hours of training in infant oral health, the pediatric primary care providers in this study achieved an adequate level of accuracy in identifying children with cavitated carious lesions. Additional training and research would be needed to optimize pediatric primary care providers' identification of carious teeth if that were the goal of screening. However, the purpose of screening by nondental personnel generally is to accurately identify those in need of referral, which does not require a tooth-by-tooth identification of cavities. Additional research is also needed to determine how to improve dental referrals by pediatric primary care providers. Results of our study suggest that dental screenings can easily be incorporated into a busy pediatrics practice and that pediatric primary care providers can significantly contribute to the overall oral health of young children by the identification of those children who need to be seen by a dentist.

Adverse events and outcomes of conscious sedation for pediatric patients: study of an oral sedation regimen

BACKGROUND

The authors report on adverse events and sedation outcomes for an oral sedation regimen of chloral hydrate, meperidine and hydroxyzine with 100 percent oxygen, or O2, supplementation.

METHODS

In a five-year retrospective study, the authors examined 195 records of conscious sedation performed in 111 healthy children aged 24 to 48 months (mean, 47 months). The authors analyzed age, sex, weight, methods of drug delivery, waiting time after drug administration, treatment rendered, treatment time, adverse events, sedation outcomes and the number of visits needed to complete treatment using descriptive statistics, chi 2 tests, t test and analysis of variance.

RESULTS

Adverse events--including vomiting, desaturation, prolonged sedation and an apneic event--occurred in 3 percent of all sedations and were minor. Seventy-two percent of sedations had satisfactory behavioral outcomes, 23 percent had unsatisfactory outcomes, and 5 percent of the cases were aborted because of disruptive behavior. Sex was not a significant factor for the success. Patient compliance with drinking medications (P = .013) and a longer waiting time after medication intake (P = .012) yielded better sedation outcomes.

CONCLUSIONS

Minimal minor adverse events occurred with this sedation regimen. The success rate was 72 percent. Compliance with taking oral medications and waiting time appeared to be important factors in predicting sedation success.

CLINICAL IMPLICATIONS

This oral sedation regimen offers reasonable outcomes with minimal adverse events under a strict protocol and use of O2 supplementation. The results also revealed associations that give guidance for case selection and outcome prediction.
