Removal of the mandibular third molar is one of the most common operations performed by oral surgeons. Many studies have been performed on postoperative complications of the operation, such as dry socket, hypoesthesia of the lower lip and tongue, and primary infection, but not on secondary infection. In this study, we examined possible factors involved in the incidence of secondary infection.<BR>A total of 1, 281 mandibular third molars were extracted at our clinic from 2002 to 2003. There were 16 cases (1.2%) of secondary infection among them. Through a logistic regression analysis, it was found that there was no relation in the incidence of secondary infection to gender of the patients in the cases and years of surgical experience in performing such operations by the doctorsinvolved. In contrast, the incidence of secondary infection was closely associated with the age of the patient, preoperative symptoms, difficulty of extraction, extraction of the contralateral mandibular third molar, and types of methods used to close the surgical wound.<BR>Twelve (75.0%) of the 16 cases of secondary infection healed within 1 month, and 15 (93.7%) healed within 3 months. There was no correlation between time to the incidence from the operation and time to heal after the incidence.<BR>These results might be useful to inform patients about potential complications of mandibular third molar extraction and to prevent the secondary infection.
