摘要
目的：定量分析乳牙合面的龋病敏感点位，为指导临床预防和治疗龋病提供依据。方法：采用激光荧光检测仪（DIAGNOdent）检测156名5～6岁儿童共561颗患龋的乳磨牙合面，记录合面龋坏最严重的位点。结果：在上颌第2乳磨牙中，龋坏最严重的位点有60．1％发生在远中窝。在下颌第2乳磨牙中，龋坏最严重的位点有51．2％发生在舌沟；而在下颌第1乳磨牙中，龋坏最严重的位点则易发生在远中窝，占该牙记录位点的34．9％。结论：不同的牙合面患龋严重部位具有统计学规律，提示这些位点是龋坏容易发生和发展的地方，是临床上预防和治疗不可忽略的重要部位。
Objective： To evaluate the caries-susceptible sites in deciduous teeth. Methods： A total of 561 deciduous molar teeth in children aged 5-6 were examined using DIAGNOdent. The most severity site in every tooth was recorded for analyzing. Results： The distal pit was the most severe site in maxillary second primary molar, account for about 60.1% of the total recorded caries sites. The lingual groove was the most severe site in mandibular second primary molar, account for 51% of the total caries sites. The distal pit was the most severe site in mandibular first primary molar, account for 34.9%. Conclusion： There are regulations for the distribution of most severe site in different tooth, which indicate these sites are most susceptible sites for caries.
