# Management of Immature Permanent Mandibular First Molar Using NeoPutty: A Case Report

## TL;DR

A child with a dental infection was successfully treated using NeoPutty, a new dental material that promotes healing and fights bacteria.

## Contribution

This case report demonstrates the successful use of NeoPutty for apexification in an immature permanent molar with an open apex and sinus tract.

## Key findings

- NeoPutty was used to place an apical plug in an immature molar with a draining sinus tract.
- The periapical lesion and sinus tract healed completely within 6 months.
- NeoPutty's biocompatibility and antibacterial properties likely contributed to successful healing.

## Abstract

Facial cutaneous sinus tracts of odontogenic origin are often misdiagnosed and improperly managed. An 8‐year‐old girl presented with a draining submental sinus tract caused by a periapical infection of her immature permanent mandibular first molar. Given the open apices and prolonged infection, apexification was planned. NeoPutty, a recently introduced premixed bioactive bioceramic cement composed primarily of tricalcium and dicalcium silicate, was selected for apical plug placement. NeoPutty has demonstrated favorable biocompatibility and antibacterial properties and has been successfully applied in primary molar pulpotomies and indirect pulp therapy. In this case, both the periapical lesion and the extraoral sinus tract healed successfully within 6 months, outcomes attributable to the material's biological and antibacterial characteristics.
