Summary
Sharp mandibular bone irregularities (SMBI) are a rare complication after lower third molar extraction. Older patients undergoing left-sided procedures face a higher risk, with symptomatic irregularities requiring surgical removal.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Complications
- Surgical Outcomes
Background:
- Lower third molar extraction is a common dental procedure.
- Postoperative complications can impact patient recovery and well-being.
- Sharp mandibular bone irregularities (SMBI) are a potential, though infrequent, sequela.
Purpose of the Study:
- To determine the incidence of sharp mandibular bone irregularities (SMBI) following lower third molar extraction.
- To identify clinical symptoms associated with SMBI.
- To ascertain potential risk factors contributing to SMBI development.
Main Methods:
- A mixed-methods approach combining retrospective cohort and case-control studies.
- Analysis of 1432 lower third molar extractions to establish SMBI incidence.
- Comparison of patients with and without SMBI to identify demographic and etiological factors.
Main Results:
- The incidence of SMBI was found to be 0.84% (12 cases).
- Advanced age was identified as the primary risk factor.
- Other significant factors included the operated side (left), presence of radiolucent images, and tooth impaction depth (erupted teeth more frequent in SMBI group).
Conclusions:
- Sharp mandibular bone irregularities are a rare postoperative complication of lower third molar removal.
- Older patients undergoing left-sided lower third molar extraction are at increased risk.
- Symptomatic SMBI should be treated by surgical removal of the irregularity.
