本研究的目的是建立一个模型来描述在混合牙列中有五种龋齿经历之一的儿童的龋齿的位置和模式。使用317名儿童的牙科记录，在私立儿科牙科诊所平均随访7.8年，以评估儿童从早期初级牙到中晚期混合牙的具体蛀牙经历。在初级牙列中没有龋齿的儿童中，有84%在混合牙列中仍然没有龋齿。乳齿混合牙列中有牙坑和牙裂隙型龋齿的患儿发生乳齿光滑面龋齿的比例（32%）高于无龋齿患儿（14%,X2 = 5.6;P < 0.05）。在初生牙列有磨牙近端病变的儿童中，57%在混合牙列的初生牙的附加磨牙近端表面发生病变。患有双舌型（奶瓶型蛀牙）的儿童在任何一组中发生额外龋齿损害的风险最高。该模型可作为前瞻性研究的基础。
The purpose of this study was to develop a model describing the sites and patterns of dental caries in the mixed dentition for children with one of five caries experiences in the primary dentition. Dental records were used from 317 children followed an average of 7.8 years in private pediatric dental offices to assess specific caries experiences in children from early primary dentition to middle or late mixed dentition. Eighty-four per cent of the children who were caries-free in the primary dentition remained so in the mixed dentition. Children with the pit and fissure caries pattern in the primary dentition were more likely to develop smooth surface caries of primary teeth in the mixed dentition (32%) than caries-free children (14%, X2 = 5.6;P less than 0.05). For children with molar-approximal lesions in the primary dentition, 57% developed lesions on additional molar-approximal surfaces in the primary teeth in the mixed dentition. Children with the faciolingual pattern (baby bottle tooth decay) were at the highest risk of any group for developing additional carious lesions. The model could serve as a basis for a prospective study.
