摘要
为研究第一恒磨牙的建及建(期延长与龋病发生发展的关系,及了解各年龄组龋均等情况,共调查2984人,其中6—8岁358人,9—12岁277人。结果:龋牙总数4663牙例,6—12岁组龋均最高(2.66),36—45岁组最低(0.87),年龄与龋均呈反关系;6—8岁组(牙合)接触率31.84％、龋发率61.93％,9—12岁组接触率62.20％、龋发率82.88％,表明建期的延长与龋病的发生、发展有直接关系。结果提示,(牙合)的正常建立与适宜的食物结构成份对发育的生理刺激十分重要;建(牙合)后,牙体通过食物磨擦的自洁功能对龋病的预防起着关键作用。
We have studied the relationships among the reocclusion and the delaying time as well as the development of the caries of the first molars. We have examined 2684 cases, and 4663 caries teeth had been found.In many cases,the time of the first molar from its reocclusion is obviously delayed, and the caries incidence is greatly increased because of no occlusal maturity in this duration. Our study showed that normal reocclusion and proper food contents are important for the physiologicalirritation of the ocelusal development. The irritation and the grind of food, the function of teeth selfcleaning can be brought into full play after reocclusionoIn this way, the caries can be well prevented.
