本研究目的為探討6-12歲學生齲齒狀況與飲食習慣、口腔衛生習慣之相關性。共有384名6-12歲學童完成口腔檢查與問卷調查。研究方法採分層集束隨機抽樣調查法,抽樣機率乃依據等比隨機抽樣。結果顯示所有學童之deft+DMFT index為4.08顆,齲齒盛行率為51.92%。常喝含糖飲料、喜歡吃糖果類甜食,且飲食無定時定量之學童容易增加齲齒的風險,在刷牙次數方面,學童每天刷牙1次比每天刷牙3次及3次以上者的齲齒齒數及齲齒經驗指數高。而口腔清潔習慣、飲食(含甜食)習慣與齲齒有顯著性相關,顯示口腔清潔習慣及飲食(甜食)習慣較差者,其口腔健康狀況較差。
The purpose of this study was to investigate the association of dental caries with dietary and dental hygiene habits. There were 384 subjects who completed both the oral examination and questionnaire. They were sampled by a stratified cluster sampling design using probability proportional to size. The overall deft+DMFT index was 4.08, and the caries prevalence was 51.92%。The frequency of brushing the teeth affected the oral health, i.e., schoolchildren who brushed only a time per day comparison with 3 times or more than 3 times had statistically significantly high dt+DT and deft+DMFT index. In conclusion, the significantly related factors with caries include dental hygiene habits and daily dietary habits (include sweet food).
