RESUMO
BACKGROUND: Root coverage procedures are very technique sensitive and require patients' compliance for successful treatment outcomes. Post operative complications can influence patients' acceptance of treatment and compromise further periodontal maintenance. AIM: The aim of this study was to evaluate the frequency and severity of complications after a modified coronally advanced flap procedure. METHODS AND MATERIALS: A total of 78 modified coronally advanced flap procedures were performed in 42 patients for root coverage. Duration of surgical procedure, history of smoking, gender, and age were recorded for each patient. A questionnaire was given to every patient to fill in at first post operative week regarding their experience of postoperative pain, swelling, and bleeding. RESULTS: Pain and duration of surgery had a correlation (OR: 1.05, P < 0.05). Post operative bleeding was significantly correlated with duration of surgery (OR: 1.03, P < 0.05). Current smokers experienced post operative swelling (P < 0.05). However, post operative pain in current smokers was not significantly different (P > 0.05) as compared to nonsmokers. Descriptive statistics were expressed as mean and standard deviations. Odd's ratio was obtained to evaluate risk indicators for moderate to severe types of complications. P < 0.05 was considered as significant. CONCLUSIONS: The duration of the surgery, long duration, and the presence of smoking can increase the frequency and severity of post operative complications.
