年轻恒牙患龋预测的前瞻性研究——龋病预防对恒牙龋病预测效果的影响

Influence of caries prevention on the caries predictive power of permanent teeth

目的:研究龋病预防措施对恒牙龋病预测效果的影响。方法:通过测定73名5岁儿童的当前患龋情况(dm fs)、唾液变形链球菌计数、唾液缓冲能力,根据已制定的标准检测出龋高/低危儿童,再分组分别采取或不采取龋病预防措施进行观察。结果:3年、5年后2组儿童龋病预测可信度有显著性差异(P<0.05),预防组比非预防组明显降低,3年后2组分别为56%、74%,5年后分别为53%、69%。结论:有效的口腔预防措施可降低未来龋病的发生,也可影响对未来龋病的预测。

AIM：To find out if effective caries prevention could influence the caries predictive power. METHODS： Seventy three children aged 5 were divided into 2 groups randomly; their dmfs index, salivary S. mutans counts and salivary buffering capability were estimated while in group 1 oral prevention was adopted and in group 2 was not. RESULTS ：The results revealed that the value of group 1 was significantly lower than that of group 2. CONCLUSION： Effective caries prevention of deciduous dentition can obviously decrease caries of permanent teeth, and influence the predictive value.
