A survey of dental disease in children of Wuvulu Island, Papua New Guinea.

A convenience sample of 153 boys and girls, aged 3-16 years, inhabiting Wuvulu Island were examined for the prevalence of dental caries and periodontal disease and for oral hygiene status. Average df teeth and surface scores for the group were 2.08 and 3.35, respectively, while average DMF teeth and surface scores were 0.90 and 1.20, respectively. Of the sample, 30.7% were caries free. Oral hygiene was poor and males had significantly more periodontal disease than females. While primary teeth were about three times more susceptible to caries than permanent teeth, tooth loss due to caries was not a problem in primary teeth. The authors discuss findings of other researchers and reasons for the greater prevalence of caries in primary teeth.

Estimation of actual caries prevalence and treatment needs from field survey caries information on a child population in U.S.A.

Caries scores (DT + Dt) were recorded under simulated field survey conditions on 270 children ranging in age from 3 to 12 years. The children were subsequently diagnosed under optimum clinical conditions. The findings from the field and clinical examinations were statistically analyzed to determine the relationships between "survey" and "true" caries scores. It is proposed that the true mean caries score can be estimated from the survey mean score by adding 1.5 teeth in the primary dentition and 2 teeth in the mixed dentition. Tables were devised to estimate treatment needs for children at various survey caries scores in each dentition category.

Children's utilization of dental care in the NC Medicaid program.

PURPOSE: To characterize the patterns of dental care in the North Carolina (NC) Medicaid Program for three- and eight-year-old children who began dental treatment in the 1985-86 and 1990-91 groups. We also compared the children's patterns of care by provider (general dentists versus pediatric dentists). METHODS: Our extensive data set included claims, enrollment, and provider data. Children were assigned to one of five categories or patterns of care as follows: complete care, general anesthesia care, sporadic care, emergency only care, and no care. Statistical comparisons of the variables age, cohort year, and provider groups were made. RESULTS: The use of Medicaid dental services by both age groups was severely limited in both yearly cohorts. Pediatric dentists tended to provide more complete and less sporadic care for both age groups and both yearly cohorts. CONCLUSIONS: Financing dental care through Medicaid results in very low levels of complete care among enrollees, and any plan that limits referral to pediatric dentists might adversely affect the number of enrollees who receive complete care.

Dental fluorosis in children exposed to multiple sources of fluoride: implications for school fluoridation programs.

Naturally occurring fluorides of varying levels made possible a study do determine if continuous, lifetime use of home drinking water fluoridated to optimum levels combined with the use of school fluoridated water beginning at school age causes objectionable levels of dental fluorosis as defined by Dr. H. Trendley Dean in 1936. Examinations were performed on 120 children who had fluoride concentrations in home well water ranging from 0.1 to 6.5 ppm and attended a school with a private water source containing 4.5 ppm natural fluoride (5.6 times the optimum for community fluoridation in the area). Fluorosis scores were calculated for each of four groups formed according to fluoride concentrations in home water supplies. The group with an average concentration of 0.87 ppm was found to have a Community Index of Dental Fluorosis well within Dean's normal limits. The results suggest that children consuming water at home containing the optimal fluoride concentration and drinking water at school containing the recommended fluoride level (4.5 times the optimum) are not at risk to dental fluorosis that impairs appearance. If this finding is corroborated by future clinical studies, the target population for school fluoridation can be expanded and the administration of these programs facilitated.

The prevalence and risk factors of fluorosis among patients in a pediatric dental practice.

Seven hundred eight patients aged 5-19 years in a pediatric practice in North Carolina were selected using a random-start, systematic sampling procedure and enrolled in a case control study to determine risks for fluorosis. Subjects were examined by four trained examiners using the Tooth Surface Index of Fluorosis (TSIF). Information on fluoride exposures and other explanatory variables was obtained through parent interviews and mail questionnaires. Fluoride exposure was confirmed by fluoride assay of community drinking water samples. Bivariate associations for the entire sample were tested using MH chi2 statistic. A secondary analysis controlling for fluoride in drinking water was performed using logistic regression for 233 subjects (116 drinking fluoridated water; 117 drinking fluoride-deficient water) who were lifetime residents at the same address. Nearly 78% of subjects had a TSIF score of > 0; 36.3% > 1; and 18.9% > 2. Twenty-two variables found in bivariate analyses (P < 0.15) to be associated with fluorosis were included in multivariate analyses. For subjects drinking fluoride-deficient water, fluorosis (1 or more positive TSIF scores) was associated with dietary fluoride supplement frequency (OR = 6.5) and age of the child when brushing was initiated (OR = 3.0). For subjects drinking fluoridated water, fluorosis was associated with age of child when brushing was initiated (OR = 3.1).

Pediatric and general dentists' participation in the North Carolina Medicaid program: trends from 1986 to 1992.

The purpose of this study was to report trends in dentists' participation in the North Carolina Medicaid program. Medicaid claims files for dental users younger than age 21 were analyzed for seven fiscal years (FY) from 1986 to 1992. Over the study period, the number of pediatric dentists filing any Medicaid claims remained constant but the number of participating general dentists decreased slightly. Intensity of participation, as measured by mean annual reimbursement and mean number of children treated per dentist, increased from FY 89 to 92 for both provider groups. The mean value of services provided for each dental users also increased slightly during the same period. The data revealed over time pediatric dentists treated a larger proportion of the youngest Medicaid dental users.
