RESUMO
Objectives: The purpose of this study is to estimate the overall frequency of complications associated with thirdmolars (M3) removal and to identify the risk factors associated with these complications. Study design: To thetransversal analysis, a researcher confidentially reviewed the records of all M3 surgery patients. The predictorvariables were demographic (i.e. age and gender), localization and position of third molar, bone removal and toothsectioning. Results: 210 patients had one or more third molars teeth removed, a total of 605 teeth. The samplesmean age was 21,6 ±9,2 years, with 1,4 woman to 1 man. Postoperative complications were recorded in 54 extractionsof third molars. The most common complications were infection (42,6%), followed by radicular fractures(11,1%) and gingival alterations (11,1%). Complications were significantly affected by 3 factors: age over 25 yearsold (p=0,002 OR 2,21), location (p=0,006 OR 2,36), bone removal (p=0,002 - OR 3,03) and tooth sectioning(p=0,00002 OR 3,59). Conclusions: The results of these analyses suggest that age, location of the tooth, boneremoval and tooth sectioning appear to be associated with a higher complication rate for M3 extractions (AU)
