一、斑釉、龋齿与年龄的关系龋齿与年龄有一定关系:乳牙萌出后不久就可患龋,至6～8岁时达到最高峰。在混合牙列期,由于乳牙逐渐脱落,代以新生恒牙,龋患率逐渐下降。12岁以后乳牙已脱落完毕,龋患率又逐渐升高,约在25岁左右渐趋平稳,中年以后又随年龄而增加。斑釉发生于釉质发育时期,而被发现于牙齿萌出之后,牙齿萌出后就不再改变了。具体说来,除第三磨牙外,从初生到8岁是产生斑釉的时期,(第三磨牙及乳牙的斑釉较少见而且实际意义不大),最敏感的年龄是2～3岁,3岁以后影响较小。有碍美观的斑釉牙主要是在前牙,一
First, the spot glaze, dental caries and the relationship between age Dental caries and age have a certain relationship: soon after the eruption of deciduous teeth can suffer from caries, to 6 to 8 years to reach the peak. In the mixed dentition period, deciduous teeth gradually shedding, replaced by newborn permanent teeth, caries prevalence decreased. Deciduous teeth have been off after 12 years, caries rates and gradually increased, about 25 years of age has become more stable after middle age and with age. Spot glaze occurs during the period of enamel development and is found to not change after the teeth have erupted. Specifically, in addition to the third molars, from the first to the age of 8 is the period of spot glaze, (the third molars and deciduous teeth spot glaze is rare and practical significance), the most sensitive age is 2 to 3 years old , After 3 years of age less affected. Prevented beauty of the glazed teeth is mainly in the anterior teeth, one
