1. Abstract

1.1 Objectives

The main objective of this retrospective study is to find out the complications of surgical extraction of third molars under local Anesthesia performed at dental department.

1.2 Methods

Patients who went surgical extraction of one or more third molars under local anesthesia between 2017 to 2019 were included. Age, gender, indication for extraction, teeth removed, procedure and complications were recorded.

1.3 Results

A total of 4,220 third molars (91.94% mandibular and 8.85% maxillary) were extracted and the majorities (54.68.7%) were from male patients. The mean age at extraction was 29 ± 5 years and most patients (58.07%) were 25–34years old. The intraoperative and postoperative complication rates were 2.08% and 32.23%, respectively. The intraoperative complications included tuberosity fracture (0.78%), root fracture (0.41%), bleeding (0.26%), soft tissue injury (0.1%) and adjacent tooth damage (0.15%). Postoperative complications swelling/pain/trismus (31.77%) and dry socket (0.36%). A statistically significant relationship was observed between those aged 35–44 years and dry socket (P = 0.010) as well as bone removal and all postoperative complications (P = 0.001).

1.4 Conclusion

Most complications resulting from third molar extractions were minor and within the reported ranges in the scientific literature. However, increased age and bone removal were associated with a higher risk of complications. These findings may help to guide treatment planning, informed consent and patient education.
