摘要
目的:探讨年轻第一恒磨牙着色窝沟的转归,尝试建立预测着色窝沟转变为龋的回归模型,筛查危险因素。方法:7～9岁儿童65名,应用DIAGNOdent激光荧光龋诊断仪对其87个第一恒磨牙的着色窝沟部位进行连续1年的监测,记录其转变为龋的时间以及dmft、患牙菌斑指数,进行口腔问卷调查,应用二值回归分析筛查危险因素,有序回归分析建立回归方程,并检验方程预测的有效性。结果:年轻恒磨牙的着色窝沟中1年内共48%转变为龋,有显著影响的危险性指标由强到弱分别是:dmft,患牙菌斑指数,甜食频率。结论:年轻恒牙的着色窝沟应结合龋易感性及时采取预防治疗措施。
Objective：To investigate the prognosis and progress of stained fissure or suspicious caries in young first permanent molars and screen the most significant risk factors which effect the progression or regression of caries.Methods：Stained fissure site of 87 young permanent molars in 65 of 79 year-old children were monitored by DIAGNOdent laser fluorescence caries diagnostic system for continuous one year until the suspiciou caries turned into caries and need to be treated,data of dmft,plaque index and oral questionnaire were recorded.Variables were tested by ordinal regression analysis to determine the most significant parameters related to prognosis of suspicious caries.Results：48% suspected caries in young permanent teeth turned into caries within one year.The most significant risk factors were（strong to weak）：Dmft,plaque index and frequency of sweet consumption.Conclusion：Preventive treatment measures should be applied to stained fissure in young permanent teeth according to individual caries susceptibility.
