A study of the relationship between community characteristics and dental caries in deciduous teeth.

Abstract

Community differences in caries prevalence in deciduous teeth were investigated. The Community Organization Data Base System (CODB) includes the data of 3-year-old children's dental examinations from 112 communities (cities, towns and villages) in Niigata prefecture in 1983, 1984 and 1985.This CODB also includes the data of 141 items concerned with community characteristics.

Caries experience in nursery school children in Sendai, Japan: Time trends from 1972–2002

“…In the present study, the caries experience in the primary dentition remained stable from the 1980's to the early part of the 1990's, but all age groups showed decrease in 1997 and 2002. This result agreed with the above-mentioned studies 22,23,25,26) . In other words, the rate of decrease was the greatest for 5-year-old, followed by 4-year-old, but it became gradual for 2 and 3-year-old ( Figs.…”

“…Also, some recent studies 22,23,25,26) on caries experience in the primary dentition have suggested age-related differences. According to the study conducted from 1975 to 1995, there was a marked decrease in caries experience in children older than 4-year-old, which was not observed in 3-year-old.…”

“…Despite these two marked decreases, the caries experience among young children remains high in Japan and in the beginning of the 2000's, the average number of carious teeth in 3 to 5-year-old in Japan was 2.0 to 2.5 times higher when compared to developed Western countries 20,21) . According to the most of surveys on caries experience in the primary dentition conducted from the 1970's to early 2000's in Japan, the caries experience had markedly decreased by the end of the 1980's, remained stable thereafter, and then decreased again during the 1990's 23,26) .…”

“…A number of reports, however, have shown that caries experience in the primary dentition remained stable or even increased slightly in the 1980's and 1990's, following a decrease in several countries 7,8,[10][11][12][13][14][15][16][17][18][19][20][21] . In Japan, several studies performed from the 1970's to the early 2000's showed that the caries experience in the primary dentition decreased markedly up to the early 1980's, remained fairly stable thereafter, and then began to decrease again in the 1990's [22][23][24][25][26] .…”

Predictors of Dental Caries Development in 1.5‐Year‐Old High‐Risk Children in the Japanese Public Health Service

“…Takatoku and colleagues (1) reported in a prospective study of 1.5-year-olds that an intensified preventive program targeting high-prediction models for adults and children that clinical variables, especially past caries experience, are confirmed as the most significant predictors. In addition, it has been reported that caries prevalence in primary teeth was different among areas (7,8), and lower caries prevalence had a close relationship to the urbanization of the community. Information related to caries predictors of primary teeth from previous reports (9,10) was also available.…”
