# Solving the Mystery: A Case Study on Treating a Mandibular First Premolar With Multiple Canals

## TL;DR

This case study describes the successful endodontic treatment of a mandibular first premolar with two canals in a 42-year-old male patient.

## Contribution

The novelty lies in highlighting the importance of monitoring anatomical variations in premolars to improve endodontic outcomes.

## Key findings

- Endodontic treatment of a mandibular first premolar with two canals was successfully performed.
- No signs of periapical disease were observed a year after treatment.
- Anatomical variations in canal structures should be closely monitored for better treatment outcomes.

## Abstract

The mandibular first premolar, which is the anteriormost tooth in the mandibular arch, differs from other teeth in that it typically has two roots and two to four canals. The current case involves treating a mandibular first premolar with two canals through endodontic therapy. The 42-year-old male patient's left mandibular first premolar was diagnosed with irreversible pulpitis. The lateral view X-ray depicted two canals. In the dental procedure, endodontic treatment involves working under an operating microscope and using magnification to treat the affected tooth. After canal shaping the tooth was treated with the crown after it had been cleaned and then adjusted for the bite. As aforementioned, no signs of periapical disease were observed when the tooth was rediscovered a year later. However, this case study indicates that any shift in the anatomy of the canal in premolars should be well monitored and controlled to improve endodontic treatment outcomes of such teeth as the mandibular first premolars.
