乳牙列色素沉着相关因素及患龋情况探讨

目的: 探讨3~5岁儿童乳牙色素沉着形成的相关因素及有色素沉着儿童乳牙列的患龋情况。方法: 对2019年12月—2020年8月于南京医科大学附属儿童医院就诊的182名3~5岁乳牙有色素沉着的儿童及200名无色素沉着儿童进行口腔检查及对监护人问卷调查,分析口腔内有色素沉着儿童的乳牙列患龋情况,色素沉着的分布范围、严重程度及色素沉着形成的相关因素。采用SPSS 20.0软件包对数据进行统计学分析。结果: 3~5岁有色素沉着儿童的患龋率及龋均低于全国和江苏省相应年龄儿童的平均水平。下颌乳切牙舌侧面为色素沉着最好发区域。色素沉着发生与进食含酱油食物的频率及儿童刷牙的执行者有关。结论: 乳牙列色素沉着的发生与患龋情况呈负相关,色素沉着的形成与大部分环境因素无明显关联,未来可能需要更多基于个体基因层面的研究。

Research on the pathogeny of black tooth stain and association between black tooth stain and primary dentition caries in children

PURPOSE: To investigate the related factors of black tooth stain in primary teeth of 3~5 years old children and caries status of primary dentition in these children. METHODS: From December 2019 to August 2020, 182 3~5 years old children with black tooth stain and 200 children without pigmentation were investigated by oral examination and questionnaire survey to their guardians, while caries status , distribution range of the pigment, factors associated with black tooth stain were evaluated. SPSS 20.0 software package was used for data analysis. RESULTS: Children with black tooth stain had fewer dental caries. The lingual surfaces of the mandibular anterior teeth were the most affected sites. Factors associated with black tooth stain were foods with soy sauce and brushing teeth with parents' help. CONCLUSIONS: There is a negative correlation between the occurrence of primary dentition caries and blacktooth stain, but there is no significant correlation between formation of black tooth stain and most environmental factors.
