PURPOSE: To evaluate the influence of 2 different flap designs on periodontal healing and postoperative complications, after inferior third molar removal in young patients. PATIENTS AND METHODS: Twenty-four mandibular third molars were extracted from 12 patients with an average age of 16 years. Patients were included in the study when radiographs at the time of surgery showed that only the crown of the germ was formed. Each patient underwent 2 extractions, using a triangular flap on one side and an envelope flap on the other. Periodontal probing was recorded at the preoperative visit, and 7 days, 3 months, and 6 months after extraction. Postoperative complications were recorded using a questionnaire completed by the patient for the week after the extraction. RESULTS: The examination performed 7 days after the extraction demonstrated a deeper probing depth in all teeth examined. This increase was statistically greater (P < .05) for the first and second molars when an envelope flap was used. After 3 months, the probing depths returned to preoperative values. No significant differences were seen between the 2 flap designs when postoperative complications were considered. The average operating time was 30.66 minutes with the triangular flap, versus 35.66 minutes with the envelope flap. This difference was not significant. After 6 months, the 2 flap designs resulted in no difference in periodontal healing or complications, but 30% of the surgical extractions resulted in a debilitating postoperative period for the patients treated. CONCLUSIONS: Although we observed statistically significant differences in probing depth between triangular and envelope flaps 7 days after the extraction of third molars with no root development, this was not important from a clinical perspective, because periodontal healing at 3 and 6 months was comparable. We believe that this is also the case with the extraction of third molars with fully formed roots. Another important finding was the presence of a debilitating postoperative period in most of the patients who underwent extraction, contrary to the beliefs of many surgeons.
