摘　　要：目的了解南京市乳牙列期儿童龋病的牙面分布规律。方法抽取南京市449位2~6岁儿童进行口腔检查并记录,分析不同牙面的患龋差异。结果龋齿牙面分布左右对称,龋面主要集中于上颌乳中切牙近中邻面,其次为乳磨牙邻面和上颌乳前牙唇面及邻面。乳前牙区牙面龋风险向中线递增,乳磨牙区下颌龋风险大于上颌,牙合面龋以第二乳磨牙为主,邻面龋风险在第一乳磨牙较第二乳磨牙大。结论乳牙龋有牙面特异性,外形相似、位置相邻的牙面其龋风险可能不同,应针对龋集中的牙面加大防治力度。Objective To investigate the regularities of caries distribution in the primary dentition of children in Nanjing,China.Methods 449 children of 2 to 6 years old in Nanjing were selected for oral examination.Regularities of caries distribution on different tooth surfaces were analyzed.Results The distribution of caries was bilateral symmetrical.The caries concentrated on the mesial surface of the maxillary primary central incisor,followed by the proximal and occlusal surface of the primary molar,and the labial and proximal surface of the maxillary primary anterior teeth.The risk of caries in primary anterior tooth surface increased towards midline;in primary molars,caries risk was higher in mandible than that in maxilla.There was higher risk of occlusal caries surface in second primary molars,and higher risk of proximal caries surface in first primary molars than that in second primary molars.Conclusion The primary tooth caries distribution has specificity in tooth surface.The caries risk of tooth surface with similar appearance and adjacent position may be different.Prevention and treatment should be strengthened on the tooth surface with high caries risks.
