Comparison of Surface Roughness of Nanohybrid Composite Before and After Brushing with Tooth Whitening Dentifrice
Main Article Content
Abstract
Aim: This study compared the surface roughness of nanohybrid composite before and after brushing with a tooth whitening toothpaste.
Background: A person's smile is a very important part of their face. It greatly affects how they feel about themselves and how they interact with others. Nowadays, people care a lot about how things look. This makes patients want more dental treatments. Composite resin restorations are a big part of daily dental work. Their use has grown because more patients want better-looking teeth. A rough surface on these direct composite resins can cause problems. It makes plaque stick more, leading to gum swelling (gingival inflammation), slight color changes on the surface, and new tooth decay (secondary caries). This study aims to compare surface roughness of nanohybrid composite before and after brushing with tooth whitening dentifrice.
Materials and Methods: Eight disc-shaped samples were made from each nanohybrid composite. The surface roughness of these discs was measured before brushing. A Stylus profilometer (Mitutoyo SJ 310) was used for this. It had a 2μm tip at a 60° angle. The device moved on the surface of the nanohybrid composite disc material to get the values. After brushing simulation, the samples were checked again for surface roughness using the Stylus profilometer.
Results: It was found that brushing did change the surface roughness. Te econom plus was less effective. This was because it had high surface roughness after the brushing test.
Conclusion: Brushing with a teeth whitening toothpaste increased the surface roughness of Nanohybrid Composite. Nanohybrid Composite samples had more surface roughness after the brushing test. So, it should not be used with tooth whitening toothpaste.
