Abstract

This research examines the resilience of polymerized compomer dental restorative to the oxidation effects of ozone (O3), with exposure times of 60, 180, 1320, and 2880 minutes. Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES) is used to observe the release of elemental strontium from the polymer into the aqueous medium, Scanning Electron Microscope (SEM) is used to record the deterioration of the polymer surface and underlying areas of the compomer material, and a microbalance is used to track the mass loss. Ozone can impact a dental polymer in three scenario’s: first is a single disinfections treatment in situ (mouth), second is a multiple treatments in situ, and the third is the immersion of a dental implant that contain the compomer in a disinfecting chamber for cleansing purposes.
