Description:

Surveys of the dental health of Native children in British Columbia, Canada, were conducted in 1980, 1984 and 1988 by Medical Services Branch, Health and Welfare Canada. Data were gathered on children turning 5, 7, 9, 11, 13, and 15 yr of age in each survey year. This paper analyzes the findings related to dental caries and the treatment of caries. Comparisons were made between the 1980 and 1988 surveys using Student’s t-tests; data from the 1984 survey were included for comparison. Results of these surveys demonstrate a continuous improvement in the dental health of Native children between the years 1980 and 1988, but the improvement was limited to the permanent dentition. The deft for 5-yr-olds remained constant over the time interval. In contrast, the DMFT for each group significantly decreased from 1980 to 1988 (P < 0.05). The percentage of 5-yr-old children who were caries-free in the primary dentition remained constant, and primary tooth mortality (tooth abscessed or with crown destroyed) in 5-yr-olds did not change. However, the percentage of children surveyed with caries-free permanent teeth improved significantly at each survey year and permanent tooth mortality significantly declined (P < 0.05). The proportion of filled, compared with carious, primary and permanent teeth increased from 1980 to 1988. In contrast, the number of extracted primary teeth stayed relatively constant for 5-yr-olds, but the proportion of missing teeth declined significantly for all other age groups (P < 0.05).
