Bilateral bifid mandibular canal: a case report using cone beam computed tomography.

Area of Science:

• Dentistry
• Radiology
• Anatomy

Background:

• The mandibular canal (MC) is a crucial anatomical structure in the mandible, housing the inferior alveolar nerve and vessels.
• Anatomical variations, such as a bifid mandibular canal (bifid MC), are increasingly recognized and can impact dental procedures.
• Prevalence rates for bifid MC vary significantly based on imaging modalities like panoramic radiography and cone-beam computed tomography (CBCT).

Observation:

• This case report details the identification of a bilateral type 1 bifid MC via CBCT examination.
• Type 1 bifid MC is characterized by an accessory canal originating from the main mandibular foramen and extending towards the third molar region.
• The specific location and morphological characteristics of this bilateral variation were meticulously documented.

Findings:

• CBCT imaging revealed a type 1 bilateral bifid mandibular canal, an uncommon anatomical variation.
• The accessory canals originated from a single mandibular foramen and extended bilaterally towards the third molar areas.
• This finding underscores the variability in mandibular canal anatomy.

Implications:

• Accurate detection of bifid MC variations is critical for safe and effective endodontic treatments, implantology, and orthognathic surgery.
• Understanding these anatomical variations can help prevent surgical complications and improve treatment outcomes in dentistry.
• Routine CBCT assessment is recommended for identifying such anomalies, ensuring patient safety during invasive procedures.
