Efficiency of risk factors causing complication during tooth extraction: A crosssectional study [Diş çekimi sirasinda komplikasyona neden olan risk faktörlerinin etkinligi: Kesitsel bir çalişma]

Objective:The aim of this cross-sectional study is to make a contribution to the practical dental education by emphasizing and grading the efficiency of risk factors causing complication during tooth extraction. Materials and Methods:The study consisted of 186 tooth extraction in 108 patients done by intern dental students between 2008 and 2009. The clinical and radiographic data of the patients and complications during extractions were recorded. Chi-square test and Odds Ratio were used in order to analyze the data statistically. Results:The complication rate of intern dental students was 20.43%. The complications were divided into 3 subgroups; crown fracture (%42.1), apical 1/3 root fracture (31.58%), and 2/3 root fracture (%26.32). Root-tip curve, root separation, alveolar bone resorption, crown destruction, restorations, number of roots, and age of the patients increased the complication rate significantly. Gender of the patients and anatomic localization of the teeth did not affect the complication rate significantly. Conclusions:The most potent risk factors were root-tip curve and root separation. The minimum effective risk factors were the number of roots and the age of the patients. In order to prevent complications, pre-operative radiological monitoring of the tooth is mandatory
