Abstract

Abstract
Aim: This work seeks to determine how certain pediatric drugs affect the microhardness of two types of resin composite materials.
Methods: Specimens made of Filtek Z350 XT and Omnichroma dental composites were prepared. The specimens from both groups of the two composite resin materials were then randomly divided into four subgroups based on the liquid drug medium they were immersed in.The used drugs were ( Antibiotic: Augmentin, Analgesic: Brufen, Antitussive and Expectorant: Oplex-N, Multivitamin: Sansovit plus). Through the use of a Vickers hardness scale, the impact of drugs on restorative materials was assessed.
Results: Filtek Z350 XT showed higher micro-hardness values. When comparing the changes (before vs. after) between the two materials for any medicine, no statistically significant differences were discovered. In Omnichroma, there were significant differences observed between drugs, Oplex-N caused the largest decrease while Sansovit plus had the least impact on micro-hardness. In Filtek Z350 XT there were no significant differences observed between drugs.
Conclusion: Filtek Z350 XT had better microhardness values compared to Omnichroma composite resin. The microhardness values of the composite resin are dependent on the patient's medication regimen and the composition of the material.
