Wettability, UV Absorption, and SEM Investigation of PMMA after Immersion in Ozone Water

Abstract

Purpose: Denture stomatitis, poor oral health, and angular cheilitis can all result from bacterial and fungal colonization. As a result, denture cleaners have been suggested to preserve the longevity of partially removable dentures and the health of the oral mucosa. The purpose of the present study was to investigate the impact of ozone water on Polymethyl Methacrylate (PMMA) by studying wettability, Ultraviolet (UV) absorption, and surface topography following soaking for 10 and 20 minutes at a 2 mg/l concentration.

Materials and Methods: A sixty-disc-shaped sample of polymethacrylate material (Ivoclar Vivadent) was fabricated for the wettability and UV absorption tests, and three bar-shaped samples of polymethacrylate material (Ivoclar Vivadent) were fabricated for the surface topography. Three groups were created: the first was the control group (immersion of samples in distal water). Second group (immersion of samples in 2 mg/l of ozone water solution for 10 min), and third group (immersion of samples in 2 mg/l of ozone water solution for 20 min). The contact angle (a wettability parameter) on the surfaces of the samples was measured after each storage period. The UV absorption test was assessed using a spectrophotometer; ANOVA was used to perform statistical analysis on the data at level 0.0.5; and surface topography was evaluated using Scanning Electron Microscopy (SEM).

Results: Based on the findings of this research, there was no statistically significant difference between the experimental and control groups when testing wettability and UV absorption. There is no change in surface topography when assessed by SEM.

Conclusion: This research concluded that the samples prepared from PMMA material can be safely soaked in an ozone water solution without compromising their properties.
