Abstract

This work aims to investigate the structural stability of a photopolymerizable composite resin when subjected to the aggressive action of some substances, possible occurring in the oral cavity when drinking, regurgitating, or in gastroesophageal reflux disease. The material stability was assessed by XRD and Raman spectroscopy in two situations (in the warranty period specified by the manufacturer, and after this period) by immersing for different time intervals in some acidic media. A modification of the structural composition was observed after hydrochloric acid treatment..
