Extraction healing complications have been attributed to several factors. The influence of trans-operative complications on an extraction site wound healing was the focus of this investigation.This prospective study was conducted at the Oral Surgery Clinic of the Department of Oral and Maxillofacial Surgery of the Lagos University Teaching Hospital (LUTH) in Nigeria . Subjects selected were those referred for one or two adjacent extractions and who satisfied the inclusion criteria for the study. The relevant pre-operative information recorded for each patient were age and sex of patient, indications for extraction, time taken to extract the tooth, tooth/teeth removed, and any trans-operative complications. Extractions were performed with dental forceps, elevators, or both under local anaesthesia. Patients were blindly evaluated on the third and seventh post-operative day for socket healing assessment without reference to pre-operative information on the patients.Seventy-three (24.25%) of 301 teeth considered for socket healing assessment had various trans-operative complications due to accidental crown, root, or alveolar bone fractures. Of the 73 extractions with trans-operative complications during extraction, 18 developed a socket healing complication, while 17 of the 228 extractions without trans-operative complications developed socket healing complications (p = .000). The mean (SD) time taken to extract teeth developing healing complications was also found to be significantly longer than those without healing complications (p.01).The study demonstrated the combination of tooth/bone fragments in the socket and increased time of extraction due to trans-operative complications and accidents predispose to the development of extraction site wound healing disturbance.

The aim of this prospective study was to evaluate the clinical pattern of post-extraction wound healing with a view to identify the types, incidence, and pattern of healing complications following non-surgical tooth extraction.A total of 311 patients, who were referred for non-surgical (intra-alveolar) extractions, were included in the study. The relevant pre-operative information recorded for each patient included age and gender of the patient, indications for extraction, and tooth/teeth removed. Extractions were performed under local anesthesia with dental forceps, elevators, or both. Patients were evaluated on the third and seventh postoperative days for alveolus healing assessment. Data recorded were: biodata, day of presentation for alveolus healing assessment, day of onset of any symptoms, body temperature (degrees C) in cases of alveolus infection, and presence or absence of pain.Two hundred eighty-two patients (282) with 318 extraction sites were evaluated for alveolus healing. Healing was uneventful in 283 alveoli (89%), while 35 alveoli (11%) developed healing complications. These complications were: localized osteitis 26 (8.2%); acutely infected alveolus 5 (1.6%); and an acutely inflamed alveolus 4 (1.2%). Females developed more complications than males (p=0.003). Most complications were found in molars (60%) and premolars (37.1%). Localized osteitis caused severe pain in all cases, while infected and inflamed alveolus caused mild or no pain. Thirty patients (12%) among those without healing complications experienced mild pain.Most of the post-extraction alveoli healed uneventfully. Apart from alveolar osteitis (AO), post-extraction alveolus healing was also complicated by acutely infected alveoli and acutely inflamed alveoli. This study also demonstrated a painful alveolus is not necessarily a disturbance of post-extraction site wound healing; a thorough clinical examination must, therefore, be made to exclude any of the complications.

The aim of the study was to review all the cases of ameloblastoma seen at the Oral and Maxillofacial Surgery Clinic of the Lagos University Teaching Hospital, Nigeria, between 1980 and 2003.In this retrospective study, case files and biopsy reports of new cases of ameloblastoma covering a 24-year period were retrieved and analyzed for sex, age on presentation, histologic type, and site distribution.A total of 207 cases of ameloblastoma were seen in the given period. One hundred and ninety-eight (95.7%) were benign, and 9 (4.3%) were malignant. A male-to-female ratio of 1.1:1 was found. The average ages on presentation for ameloblastoma and ameloblastic carcinoma were 31.67 and 46.44 years, respectively. The lesion was found to be more common in the premolar-molar region of the mandible. The most common histologic type was follicular ameloblastoma (25.1%). Nine (4.3%) cases of ameloblastic carcinoma were also reported.Ameloblastoma with a predilection for the posterior mandibular region is relatively common in our environment. Sex and site distributions are similar to previous reports in the literature.
