Evaluation of tooth color, whiteness changes and sensitivity following laser-assisted in-office tooth bleaching using Er,Cr:YSGG laser: A prospective clinical study

Purpose of the Study

This study aimed to evaluate how tooth color, whiteness, and tooth sensitivity change after teeth whitening treatments. We wanted to see if using a special laser during the whitening process made a difference.

Methodology

We enrolled 20 participants for the study. Each participant underwent two 20-minute whitening sessions using a 40% hydrogen peroxide bleaching gel. One side of the mouth received laser treatment, while the other side did not. We measured tooth color and whiteness immediately after treatment, and again after 7 and 30 days. Tooth sensitivity was assessed during the treatment using a simple scale.

Key Results

Both whitening methods showed significant improvements in tooth color and whiteness right after the treatment. However, these improvements gradually faded over 7 and 30 days. Notably, the laser treatment showed better results in canines and lower central incisors. About 85% of patients experienced mild tooth sensitivity, but there was no notable difference in sensitivity between the two methods.

Clinical Significance

The study suggests that using the Er,Cr:YSGG laser for tooth whitening can enhance color and whiteness changes, particularly in certain teeth, without causing more sensitivity than traditional methods.

Opportunities for Clinics and Patients

Based on the study results, clinics can set measurable goals for improving patient satisfaction with tooth whitening. They can implement this laser-assisted approach to achieve better outcomes for specific tooth types.

AI Tools for Clinical Needs

Selecting AI tools tailored for specific tasks related to tooth whitening can help clinics optimize their treatment processes and improve patient care.
