Abstract:

Objective To investigate the oral health status among 12-year-old children in Sichuan province and monitor the tendency of dental caries. Methods A stratified multistage random sampling design was applied and a total of 768 12-year-old children were selected from 3 urban sampling spots and 3 rural sampling spots. All
examinees answered an oral health knowledge questionnaire and were examined by experienced dentists. Results The prevalence rate of caries of this group of 12-year-old children in Sichuan Province was 42.18%, its mean DMFT was 0.94±1.44. Urban children showed higher prevalence rate and DMFT than the children in countryside did（P<0.05）. Percent of filled teeth was only 8.10%. Percnet of children having daily consumption of carbonated drinks, desserts and candy equal or more than once daily was separately 97.01%, 88.8%, 88.28%. Children taking sweets before sleep accounted for 75.52%; 40.0% of the children brush their teeth twice or more than twice daily, 21.6% of the children is using fluoride toothpaste; only 13.80% of the children agree that fluoride toothpaste is good for teeth. Conclusion This group of 12-year-old children in Sichuan Province has a high rate of caries teeth and the treatment rate is low. Due to high caries-risk factor including being lack of oral health knowledge and poor oral health habit, long-term monitoring and strengthened protection should be part of work in the future.
