Summary
The Er: YAG laser shows potential for impacted lower third molar removal, with lower pain and bleeding compared to surgical burs. However, it requires more time and may increase trismus, though outcomes are comparable.
Area of Science:
- Oral and Maxillofacial Surgery
- Laser Dentistry
- Minimally Invasive Procedures
Background:
- Impacted lower third molar removal is a common surgical procedure.
- Surgical burs are traditionally used for bone cutting during extraction.
- Er: YAG laser presents a potential alternative for bone cutting in dental surgery.
Purpose of the Study:
- To evaluate the feasibility of Er: YAG laser for bone cutting in impacted lower third molar extraction.
- To compare the clinical outcomes of Er: YAG laser versus surgical bur in this procedure.
Main Methods:
- A comparative study involving 40 patients with impacted mandibular third molars.
- Patients were randomly assigned to either Er: YAG laser or surgical bur group for extraction.
- Clinical parameters including pain, bleeding, operative time, swelling, trismus, wound healing, and complications were assessed.
Main Results:
- The Er: YAG laser group exhibited lower pain, bleeding, and postoperative swelling, with the swelling difference being statistically significant.
- Bone cutting with the Er: YAG laser took approximately double the time compared to the surgical bur.
- Trismus was more prolonged in the laser group, while wound healing and complication rates were similar between groups.
Conclusions:
- Er: YAG laser is a feasible option for bone cutting in impacted third molar surgery, suitable for minimally invasive approaches.
- It can be considered an alternative to surgical burs, particularly for anxious patients.
- Further research may explore optimizing laser parameters to reduce operative time and trismus.
