抜歯後感染に関する臨床的検討

抄録

Cases with postoperative infections following teeth extraction are experienced occasionally, however, there have been few reports about the problems following teeth extraction. The purpose of this study was to investigate the influence of general and local background of cases with infections following teeth extraction. The results were as follows:
1) The infections following teeth extraction occurred in 11 (2.1%) out of 517 cases.
2) There was no relationship between age or underlying disease and the postoperative infection rate.
3) The incidence of the infection was the highest after mandibular third molar surgery, however, the relationship between the surgical procedure such as incision or removal of the bone and the infection rate was not found.
4) The infection rate of cases with acute inflammation before surgery was higher than that of the cases without any inflammatory signs.
5) Prophylactic antibiotic administration was performed on 282 (54.5%) out of 517 cases. The incidence of the infections of the cases with prophylaxis was almost the same as the cases without prophylaxis.
6) The postoperative pain in infection cases tends to last longer than the normal course. Therefore, it is important to observe carefully the course of pain to make a diagnosis of postoperative infection.
