# Endodontic Treatment of Maxillary Premolar With Three Roots: A Case Report

## TL;DR

This case report describes a successful endodontic treatment of a maxillary premolar with three root canals using advanced techniques and imaging.

## Contribution

The report highlights the effective use of microscopes, CBCT scans, and specific surgical methods in treating a rare three-root canal premolar.

## Key findings

- The use of a dental operating microscope improved accuracy in treating complex root canals.
- CBCT scans and X-rays were crucial for assessing and guiding the treatment process.
- Warm vertical compression and root canal microsurgery were successfully applied in this case.

## Abstract

Background: The aim of this case was to understand and treat the intricate root canal anatomy observed in complex maxillary first premolars, particularly those exhibiting three root canals, emphasizing the significance of understanding root canal morphological variations in their treatment.

Conclusions: This case reported the methods of treating three-root canal maxillary first premolars, including warm vertical compression technique, root canal microsurgery, and the application of rubber dam. The utilization of dental operating microscopes, various surgical strategies, and key assessments of X-rays and cone beam computed tomography (CBCT) scans were all essential steps for achieving accurate and safe root canal therapy.
