一、绪言拔牙术在口腔外科临床工作中比例极大,而创面愈合过程也不是完全顺利的。至今,对愈合过程仍有很多问题在探讨。以往的研究多以动物(或人)的拔牙创做组织学研究,但在临床上仅借助X线学,对骨性修复作临床统计或简单的临床观察。因此,作者采用对一次拔一个牙的症例,从临床角度观察,并对术前后正常或异常等因素之间的关系行严密定时复查,现陈述于下。 I. INTRODUCTION Tooth extraction has great clinical practice in oral surgery, and wound healing process is not completely smooth. So far, there are still many questions about the healing process. In the past, many researches on animal (or human) tooth extraction were used for histological study. However, in clinic, X-ray alone was used to make clinical statistics or simple clinical observation of bone repair. Therefore, the author adopts a case of pulling one tooth at a time and observes from a clinical point of view, and conducts a close examination on the relationship between normal and abnormal factors before and after the operation.
