The effects of gastric acid on pediatric restorative materials: SEM analysis

In this study, we aimed to demonstrate changes in the surface roughness and microhardness of three different restorative materials routinely used pediatric dentistry (composite, compomer resin-modified glass ionomer cement (RMCIS)) response continuous daily exposure gastric acid. Twelve samples each type material were prepared. Eleven specimens included acid cycle. The ten measured before after Another sample cycle was compared with not by scanning electron microscopy (SEM). There a significant difference between groups terms scores following (p = 0.039). RMCIS possessed highest value. A identified levels 0.001). most change observed material. SEM analysis, performed cycle, revealed that cracks material; followed composite materials, respectively. Our analysis indicates frequently dental procedures, show increased reduced when exposed
