AbstractAim: The aim of this retrospective study was to identify the fate of the third molar along the line of fracture in mandibular angle fracture.
Materials and Methods: A Retrospective study was conducted in the Department of Dentistry, Narayan Medical College and Hospital, Sasaram, Bihar, India,for 1 year. Total 120 cases were enrolled for the study, divided into two groups-group 1 in which third molar was retained and group 2 in which third molar was extracted. The cause for removal included development of pain, redness, discharge indicating periodontal problems including mobility and periapical lesions. Keeping the progress of healing of the bone in mind these teeth were extracted.
Result: The mean age group of the population of the study was 32.95 (20 to 60 years), out of which majority of the cases 83.33%(100) were male patients and 16.67%(20) were female patients. There were a total of 120 patients with mandibular angle fracture who underwent open reduction and internal fixation. 33.33% (n=40) the third molar was removed, while in 66.67% (n=80) retained. The etiology of the cases were attributed to RTA and assault, the former being in majority of cases, i.e. 79.17% and 21.83% respectively. The side of the angle fracture in this study were almost similar, incidence of left side fracture being 54.17% and the right side fracture being 45.83%. In 45.83% (55) cases the third molar was completely erupted and 54.17% (65) were impacted third molars. In the impacted molars 49.23% were mesioangular, 35.46% were vertical and 12.31% were distoangular. At 4 months follow up, based on the signs of infection it was decided to extract the third molars. The signs and symptoms considered were –pain, redness or discharge at the third molar site. At the end of the 4 month, 12 cases showed signs of infection in the retained group due to which extraction of the third molar was carried out under local anesthesia following aseptic precautions. There were no re fractures during extraction. Out of the 120 cases included in this study 16 cases underwent implant removal. 10 case in retained group and 6 in the removal group. In the retained group, extraction of the third molar was carried out along with removal of the implant.
Conclusion: We conclude that the partially impacted tooths are best to be removed during the procedure for better outcomes provided the fractured segments stability is maintained.
