高发龋和无龋儿童口腔健康行为及相关因素分析

目的探讨儿童乳牙龋高发的危险因素。方法检查广州从化市401名3～4岁儿童的口腔健康状况，对儿童父母进行问卷调查，选择120例高发龋（dmft≥5）患儿及118名无龋儿童进行对照分析。结果Logistic回归分析表明，刷牙频率、甜食频率、可视菌斑指数、釉质发育缺陷和家庭收入对儿童是否高发龋的影响最为显著。结论提倡儿童每天至少刷牙两次，控制甜食摄人次数，减少釉质发育缺陷，将低收入人群作为重点人群，对于预防乳牙龋的高发均具有重要意义。

A study on oral health behavior and other related factors between children with high dmft and no caries

OBJECTIVE: To explore the risk factors of children with high dmft. METHODS: In suburban of Guangzhou, oral health of 401 3 - 4-year-old children were examined and structured questionnaire were completed by their parents. 120 children with highest number of dmft (dmft > or = 5) and 118 caries-free children were chosen for case-control analysis. RESULTS: The results of logistic regression analysis showed that the factors associated with high dmft were developmental defect of enamel, visible plaque index, frequency of toothbrushing, frequency of sugar consumption, and income. CONCLUSIONS: Advocating brushing teeth at least twice daily, controlling the frequency of sugar consuming, reducing the developmental defect of enamel and paying more attention to the oral health of lower income population may effectively reduce dental caries of the children.
