我科借助电子计算机对1985年6—12月就诊的3663例恒牙拔除患者的原因进行了统计和分析,结果表明:恒牙拔除的主要原因为牙周病,有1386例,占拔牙例数的37.84％.其次为龋病,有1177例,占33.89％。与北医统计的龋病占第一位、牙周病占第二位不同。阻生牙的拔除也较其它文献报导的资料为高,有486例,占13.27％。尖牙、埋伏牙和正畸牙拔除最少。第三磨牙是恒牙拔除最多的牙位,有1025颗,占拔牙数的23.02％,其次是第二磨牙,有732颗,占16.44％,第一磨牙占第三位,有678颗,占15.23％.47.51％的第三磨牙拔除是因阻生所致。由于阻生常常引起一系列并发症,而且在功能上又无多大作用,所以,是招致拔除的主要原因。第一磨牙的拔除低于第二、三磨牙的原因是医务工作者对第一磨牙的保留治疗极其重视,以致拔除减
Our department used computer to analyze the reason of 3663 permanent teeth removal patients who visited from June to December in 1985. The results showed that the main reason of permanent tooth extraction was periodontal disease, there were 1386 cases, accounting for the number of tooth extraction Of the 37.84%, followed by dental caries, there are 1177 cases, accounting for 33.89%. Caries statistics with the North occupy the first place, periodontal disease accounted for the second place. Impacted teeth were also removed more than the data reported in other literature, 486 cases, accounting for 13.27%. Fangs, impacted teeth and orthodontic teeth removed the least. The third molars were the most removed teeth in permanent teeth, with 1025, accounting for 23.02% of the number of tooth extraction, followed by the second molars, with 732, accounting for 16.44%, the first molars accounted for the third, with 678, accounting for 15.23% .47.51% of the third molar removal is caused by the impaction. Because obstruction often causes a series of complications, but also functionally little effect, so is the main reason leading to removal. The reason why the removal of the first molars is lower than that of the second and third molars is that the medical workers attach great importance to the retention treatment of the first molars,
