# Effect of mouth rinses on roughness and optical properties of restorative materials for oral rehabilitation

## TL;DR

This study examines how different mouth rinses affect the surface roughness and optical properties of dental restorative materials.

## Contribution

The study provides new insights into how various mouth rinses impact the performance of specific dental restorative materials.

## Key findings

- Roughness increased for Ivotion Dent and Ivotion Base after all mouth rinses.
- Soft-Tissue and Cosmetic rinses increased roughness in Empress Direct.
- Optical properties like translucency and contrast ratio changed differently depending on the material and rinse used.

## Abstract

The objective of this study was to evaluate the influence of mouth rinses on the roughness and optical properties of three polymeric restorative materials. Cylinders were obtained from Ivotion Dent, Ivotion Base, and Empress Direct. Nano-hybrid composite teeth were also investigated (SR Phonares II). Specimens were divided into four subgroups for mouth rinsing simulation according to the mouth rinse: (1) Distilled water; (2) Soft-Tissue; (3) Implants/Cosmetic; and (4) PerioGard. Roughness (Ra) and optical properties were evaluated before and at timepoints during mouth rinsing simulation. Roughness increased after rinsing simulation for Ivotion Dent and Ivotion Base after all mouth rinses. Soft-Tissue and Cosmetic increased the Ra of Empress Direct. Translucency parameter (TP) of Ivotion Dent and Empress Direct increased, while Contrast ratio (CR) values decreased after rinsing simulation, regardless of the solution used. Ivotion Base demonstrated higher TP after rinsing with Soft-Tissue and Implants mouth rinses compared to the control group, while no difference among them was observed for CR. The mouth rinses affected the roughness and optical properties of materials differently after the rinsing simulation.
