The chronology of the wound healing process following tooth extraction was studied by means of two kinds of histological cuts. Two groups of 42 albino rats were employed. In the first one, the sockets were cut in a transversal way. In the second one the cuts were performed in a longitudinal way. The rats were sacrificed after 3, 6, 9, 15, 21, 24, and 28 days following the surgeries. After laboratorial outline the obtained pieces were stained by hematoxylin and eosin for histological purposes. It way be concluded that: 1. The results got from longitudinal cuts were in agreement to those described by other authors; 2. The transversal cuts allow us to detect intensive resorption of the lateral alveolar wall at the cervical thirs; 3. On the 21st day following dental extraction the incisor socket of the rat shows a great deal of areas not ossified; 4. The healing process of dental extraction wounds of the upper incisor of the rat is completed between 24 and 28 post operative days.
通过两种组织学切片方法研究了拔牙后伤口愈合过程的时间顺序。使用了两组各42只白化大鼠。第一组，牙槽窝以横向方式切开。第二组，切口以纵向方式进行。在手术后3、6、9、15、21、24和28天处死大鼠。经过实验室处理后，所获得的组织块用苏木精和伊红染色用于组织学观察。可以得出以下结论：1. 纵向切片得到的结果与其他作者描述的结果一致；2. 横向切片使我们能够检测到颈部三分之一处牙槽侧壁的强烈吸收；3. 在拔牙后第21天，大鼠的切牙牙槽窝显示出大量未骨化的区域；4. 大鼠上切牙拔牙伤口的愈合过程在术后24至28天之间完成。
