Area of Science:

Dentistry
Endodontics
Dental Anatomy

Background:

Mandibular first molars typically exhibit specific root and canal configurations.
Variations in root canal anatomy can complicate endodontic procedures.

Observation:

A right mandibular first molar presented with an unusual anatomy requiring root canal treatment.
The molar had one mesial root and two distal roots.

Findings:

A total of five root canals were identified in the molar.
The mesial and distobuccal roots each contained two separate canals.
The distolingual root had a single canal.

Implications:

This case highlights the importance of thorough radiographic and clinical examination in endodontics.
