SALMEN, Fued Samir et al. Third molar extractions: a retrospective study of 1178 cases. RGO, Rev. gaúch. odontol. (Online) [online]. 2016, vol.64, n.3, pp. 250-255. ISSN 1981-8637.

This study aims to investigate the demographics, patient health status, position of the teeth, pericoronitis incidence, surgical complications, use of antibiotics to third molar removal and correlate those findings. Methods Based on panoramic radiographs, the teeth were classified as proposed by Pell and Gregory and Winter. The binomial test for proportions with a significance level of 5% was applied. Results Records of 337 patients submitted 1178 third molar extractions in the period from 1993 to 2011 were reviewed. Most upper teeth were vertically positioned, (84.2%) (p<0.0001), class I (49.55%) (p<0.0001), position C (58.88%) (p<0.0001) and most inferiors were mesioangulated (42.03%) (p<0.0122), class II (60.22%) (p<0.0001), position A (48.15%) (p<0.0001). Complications occurred in 2.88% of the procedures (p<0.0006), mainly in women (69.7%) (p<0.0014) and more frequently in patients who did not receive antibiotics (71.43%) (p<0.0027). Complications were more frequent after extraction of inferior third molars (75.75%) (p<0.0001). The most common complication was alveolitis (52.51%) (p<0.0006). Conclusion In this study, the complication rates were low. They were more frequent in women who did not receive antibiotics. The most common complication was alveolitis.
