目的了解学龄前儿童牙面色素沉着形成的原因及其形成与乳牙龋病的关系。方法于2012年5—6月随机选取青岛市市南区3所公立幼儿园的434名3~6岁乳牙列儿童,由2名医生按WHO推荐的龋齿检查方法,对其进行龋齿及牙面色素检查,并对儿童家长进行关于儿童饮食结构及习惯、口腔卫生、刷牙习惯、用药史等方面的调查,调查结果采用SPSS15.0统计软件进行分析。结果学龄前儿童牙面色素沉着发生率为14.75%,男、女性儿童差异无统计学意义(13.95%vs 15.53%,χ2=0.21,P>0.05);有色素儿童患龋率为43.75%,无色素儿童患龋率为62.7%,二者比较差异有统计学意义(χ2=8.16,P<0.05);色素的发生与进食含色素的食物或饮料的频率、进食海产品的频率以及使用抗生素的频率有关。结论学龄前儿童牙面色素沉着形成原因复杂,并且其形成与龋病发生呈负相关。
Objective To understand the causes and formation of dental hyperpigmentation in pre-school children and its relationship with deciduous dental caries. Methods From April to June 2012, 434 children aged 3 to 6 years old with pediatric dentition 3 to 6 years old from 3 public kindergartens in Shinan District of Qingdao were randomly selected. Two doctors examined caries according to the WHO recommendation and performed dental caries and facial pigment Check, and children’s parents on the diet and habits of children, oral hygiene, brushing habits, medication history and other aspects of the survey results using SPSS15.0 statistical software for analysis. Results The incidence of dental hyperpigmentation in preschool children was 14.75%. There was no significant difference between male and female children (13.95% vs 15.53%, χ2 = 0.21, P> 0.05). The prevalence of dental caries in pigmented children was 43.75% Pigment prevalence of caries in children was 62.7%, the difference was statistically significant (χ2 = 8.16, P <0.05); the occurrence of pigmentation and the frequency of eating foods or beverages, the frequency of eating seafood and the use of antibiotics Frequency related. Conclusion There are complex reasons for the formation of dental hyperpigmentation in preschool children, and their formation is negatively correlated with the occurrence of dental caries.
