摘要
目的 评价并发现产生乳牙继发龋的相关危险因素。方法 收集乳牙因龋充填在一年以上的临床病例 32 2名 ( 982颗乳牙 ) ,并进行Logistic回归分析。结果 乳牙继发龋的发生与充填时间、口腔内龋损牙数、菌斑指数呈正相关 ,银汞合金为最不易发生乳牙继发龋的充填材料 ,在本院儿童牙科充填的乳牙龋洞继发龋发生率较低 ,同时乳前牙较乳后牙因龋充填易发生继发龋。结论 充填时间、口腔内龋损牙数、菌斑指数、充填材料、治疗单位、充填牙位是乳牙继发龋可能的危险致病因素。
ObjectiveThe aim of this study was to assess and find the risk factors related to secondary caries of primary teeth.MethodsNine hundred eighty-two primary teeth which had been filled for more than one year were selected and analyzed with logistic regression analysis.ResultsOccurrence of secondary caries of primary teeth has positive relative to the filled time,the number of dental caries and plaque index.The lowest susceptible filling material was amalgam.The occurrence rate of secondary caries of primary teeth in stomatology hospital were lower than that in other hospital.Simultaneously,the risk of secondary caries of primary teeth is higher in front teeth than in back teeth.ConclusionIt was comsidered that filling time,the number of dental caries,plaque index,filling material,treating place and filling position may be the risk factors esultedin secondary caries of primary teeth.
