Effect of different pediatric medications on various tooth colored restorative materials used in pediatric dentistry

Abstract

Aim: To study and compare the effect of different pediatric medication on tooth-colored restorative materials. Method: One fifty specimens, 50 of each restorative material RMGIC, Compomer and Composite were obtained using circular acrylic mold with a diameter of 5mm and thickness of 2mm and A2 shade for standardization. They were further divided into five subgroups of multivitamin, antiepileptic, anxiolytic, bronchodilator and distilled water as control group. The specimens were immersed in syrup for 2 minutes twice a day for 40 days. The effect of medications on tooth colored restorative material was analysed by evaluation of colour stability using spectrophotometer and surface microhardness using Vikers hardness tester. Two-way analysis of variance (ANOVA) was used for multiple subgroup comparison. Result: All the materials showed statistically significant change in microhardness and color values after immersion in different syrups from baseline to 40th day period (p<0.05). The maximum and minimum change in surface hardness was observed with RMGIC in antiepileptic (14.58) and multivitamin group (8.05) (p=0.000). Also, significant color change was noticed most with RMGIC in anxiolytic group (15.73) and least with composite (7.06) in antiepileptic group (p=0.000).
