Prevalence of dental decay in Jewish and Arab schoolchildren in the Jerusalem area

The purpose of this survey was to gather up-to-date information on the prevalence of dental decay in schoolchildren in the Jerusalem area. Close to 650 Arab and Jewish schoolchildren aged 6-8 yr underwent oral examinations. The relationship between caries prevalence and treatment supplied with some secondary factors was studied. The results show that 92% of the children were affected by decay. Compared to former years there is an increase in the prevalence of dental caries throughout the population. No significant differences were found when sex, ethnic population or socioeconomic factors were related to caries prevalence. However, when DMF is broken down into its components, Arab children were seen to have a greater number of teeth affected by caries and in need of treatment (D). In contrast, treatment need has been met to a much greater degree among Jewish children than among Arab children. Data and explanations are offered.
