Bifid mandibular canals in panoramic radiographs
Journal of the American Dental Association (1939)
|June 1, 1985
Summary
Bifid mandibular canals, anatomic variations in the jaw, are not rare, found in 0.95% of 6,000 panoramic radiographs. Understanding these variations is crucial for dental procedures.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Radiology
Background:
- Anatomic variations of the mandibular canal can complicate dental procedures.
- The prevalence and classification of specific variations like bifid mandibular canals require further investigation.
Purpose of the Study:
- To identify and classify specific anatomic variations termed "bifid mandibular canals."
- To present potential solutions for clinical challenges posed by these variations.
Main Methods:
- Analysis of 6,000 panoramic radiographs.
- Identification and classification of bifid mandibular canals.
- Development of a classification system for these variations.
Main Results:
- Identified 57 instances of bifid mandibular canals.
- Reported an incidence of 0.95% for bifid mandibular canals.
- Established a classification system for bifid mandibular canals.
Conclusions:
- Bifid mandibular canals are a relatively common finding.
- Awareness of these variations is important for anesthetic, surgical, and prosthetic procedures.
- Alternative radiographic views like the lateral jaw view can be used when panoramic equipment is unavailable.
