Abstract

Aim: To investigate the indications for disimpaction of mandibular third molars and to determine the frequency and types of complications following third mandibular molar surgery.
Patients and Methods: Prospective study over a five year period (2007-2011, inclusive). Data was collected with questionnaire, by interview and following clinical examination. Data obtained was subjected to descriptive statistics and test of associations with obtained results presented as mean ± standard deviation (SD), frequency (percentages) tables and charts. P-values less than 0.05 were considered significant.
Results: Three hundred and eighty-four patients met the inclusion criteria, were fully compliant during the study period and were used for the study giving a compliance rate of 86.3%. Age range is 18-53 years, mean ± SD is 30.5 ± 4.2 years. More females representing 53.1% of the study population was recorded. Most (55.7%) of the impacted molars were removed due to recurrent pericoronitis, while orthodontic reasons contributed the least to the indications for extraction (4.7%). The incidence of complication was 11.7%. The most common complication was persistent swelling, accounting for 58.9% of the total complications. A significant association was noted between complications and socials habits, such as drinking and smoking.
Conclusion: Recurrent pericoronitis is the most common indication for disimpaction. The frequency of complication is 11.7% of total teeth removed and the incidence of complications has a significant association with the use of alcohol and tobacco
