Summary
Lingual concavity in the mandible, a potential cause of surgical bleeding, is common. Cone-beam computed tomography (CBCT) can identify this anatomical variation, preventing complications.
Area of Science:
- Dental anatomy
- Oral surgery
- Radiology
Background:
- Lingual concavity in the mandible can lead to cortical perforation and severe intraoral hemorrhage during surgery.
- This anatomical variation poses a risk to the upper respiratory tract.
Purpose of the Study:
- To determine the prevalence of lingual concavity in the interforaminal region.
- To investigate the relationship between lingual concavity, gender, and dentate status.
Main Methods:
- Retrospective analysis of 106 cone-beam computed tomography (CBCT) scans.
- Examination of bone morphology in the interforaminal region using Galileos device.
- Analysis of lingual concavity frequency, angle, and depth.
Main Results:
- Type III lingual concavity (enlarging towards labiolingual) was the most frequent type (77.9%).
- The average lingual concavity angle was 76.5 degrees, and the average depth was 2.09 mm.
- Prevalence varied between genders and dentate statuses (data not detailed in abstract).
Conclusions:
- Cross-sectional CBCT imaging is effective for detecting lingual concavity.
- Early detection of lingual concavity can prevent surgical complications like lingual cortical perforation.
