六龄齿是恒牙列中的第一磨牙,儿童六岁左右开始萌出,它是终生咀嚼工具之一,是龋齿发病率最高的牙齿,据我们对2065名学生的龋齿调查,共查出804颗龋齿,其中六龄齿就有653颗,占病牙数的81.2%,下颌牙列发病比上颌牙列发病高几倍,下颌牙列发病占病牙数的87%,这说明龋齿发疾率较高,而主要在六龄齿上,而下颌牙列的六岁龄齿发病比较突出,故应抓好六龄齿龋齿的予防,首先要抓好下颌六龄齿龋齿的预防,经常观察六龄齿荫出后的发育情况,并指导口腔卫生保健,这是降低龋齿发病率的关键。
Six-year-old tooth is the first molar in the permanent dentition. Children begin to erect when they are about six years old. It is one of the lifelong chewing tools and is the tooth with the highest incidence of dental caries. According to our dental caries survey to 2065 students, 804 There were 653 dental caries, accounting for 81.2% of the total teeth. The incidence of mandibular dentition is several times higher than that of maxillary dentition, and the incidence of mandibular dentition is 87% of the number of dental diseases. This shows that dental caries Rate, but mainly in the six-year-old teeth, and the incidence of mandibular dentition six-year-old teeth more prominent, it should do a good job of six-year-old dental caries prevention, we must first grasp the prevention of mandibular sixth-degree dental caries, often observed Six-year-old shade after the development of the shade, and to guide oral health care, which is to reduce the incidence of dental caries key.
