Text: Root number (P ((1)) < 0. 004 *) and morphology (P ((1)) < 0. 031 *), tooth position (P ((1)) = 0. 001 *), periodontal space (P ((2)) < 0. 004 *) and second molar relation (P ((1)) = 0. 001 *) were significant predictors of surgical difficulty, whereas patient age (P ((1)) = 0. 097), gender (P ((1)) = 0. 470), body mass index (P ((1)) = 0. 719), associated pathologies (P ((1)) = 0. 237), relation with mandibular canal (P ((1)) = 0. 384) and width of 3rd molar crown (P ((1)) = 0. 154) were not significant predictors.
