Summary
Partial removal of the third mandibular molar, especially with complex root anatomy, showed a high healing rate one year post-surgery. This technique may be a viable alternative for specific dental cases.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Periodontology
Background:
- Partial removal of the third mandibular molar is often considered when apices are near the mandibular canal or root anatomy is complex.
- Assessing long-term outcomes of this surgical approach is crucial for patient management.
Purpose of the Study:
- To evaluate the postoperative status one year after partial removal of the third mandibular molar.
- To establish criteria for defining healing and unsatisfactory healing based on clinical and radiological findings.
Main Methods:
- Thirty-three third molars with proximity to the mandibular canal or complicated root anatomy were selected.
- Clinical and radiological examinations were performed one year postoperatively.
- Root fragment migration and patient symptoms were recorded.
Main Results:
- Twenty-seven root fragments showed coronal migration (1-7 mm).
- Nine patients (27%) experienced subjective symptoms or objective findings, including three with dysesthesia.
- Healing was observed around 24 root fragments (73%), with unsatisfactory healing around 9 (27%).
Conclusions:
- Partial removal of the third mandibular molar demonstrates a high rate of healing one year postoperatively.
- The findings suggest that partial removal can be a safe and effective alternative in cases with complicated root anatomy.
- Further research with defined criteria for healing is warranted.
