# Navigating the Endodontic Challenge of a 40 mm Canine and Its Technical Adaptations

## TL;DR

This paper describes a successful dental treatment of an unusually long tooth using special tools and techniques.

## Contribution

The novelty lies in the technical adaptations used to treat an abnormally long canine, including a modified hand file and a side-vented microcannula.

## Key findings

- A working length of 40.7 mm was achieved in a maxillary canine with symptomatic irreversible pulpitis.
- The patient remained asymptomatic for six months after treatment, indicating successful endodontic management.
- The use of a modified hand file and side-vented microcannula enabled effective irrigation and instrumentation.

## Abstract

Aim. The aim of this case report is to present the successful endodontic management of an abnormally long right maxillary canine diagnosed with symptomatic irreversible pulpitis, highlighting the technical adaptations employed during treatment. Summary. Technical adaptations included modifying the handle of the endodontic hand file and utilizing a side-vented microcannula for irrigation using positive and negative pressure technique. Despite the challenges posed by the abnormal tooth length, the procedure achieved a working length of 40.7 mm, and periapical radiography confirmed the master gutta-percha reaching full working length. Notably, the patient remained asymptomatic during the six-month follow-up, highlighting the efficacy of the treatment. This article also reviews the current literature, examining comparable cases and techniques documented in scholarly sources.
