# Effectiveness of using a single-shade universal resin composite before internal bleaching: a 15-month follow-up case report

## TL;DR

A single-shade resin composite used before tooth bleaching maintains color harmony and offers a time-efficient dental treatment.

## Contribution

Demonstrates the effectiveness of single-shade resin composites in achieving aesthetic results before internal bleaching.

## Key findings

- The resin composite color matched the tooth structure 15 months post-bleaching.
- The treatment reduced chair time and preserved tooth structure.
- The method is minimally invasive and easy to handle clinically.

## Abstract

Single-shade universal resin composites allows light transmission from the surrounding tooth structure and light emission at a specific frequency, and it can reduce skill complexity, chair time, and inventory requirements. The present article aimed to demonstrate the aesthetic outcomes of restoring a tooth with a single-shade universal resin composite before internal bleaching.

A 55-year-old female patient presented with an internally discoloured maxillary left lateral incisor and underwent treatment involving the application of a single-shade resin composite before internal bleaching. Fifteen months after bleaching, the colour of the direct restoration remained in harmony with the surrounding tooth structure, achieving clinically acceptable aesthetics. Direct restoration using a single-shade resin composite before internal bleaching reduced chairside time, preserved tooth structure, and eliminated the need for interim restoration.

The combination of single-shade resin composite restoration and internal bleaching offers a minimally invasive, time-saving, and easy-to-handle treatment option with acceptable aesthetic outcomes.
