Pulp Capping Materials Alter the Toxicity and Oxidative Stress Induced by Composite Resins in Dental Pulp Culture

摘要

Direct pulp capping involves covering exposed pulp to preserve its viability. Calcium hydroxide materials have traditionally been the most commonly used pulp capping compounds; however, they can be toxic, and their success rate in pulp capping is variable. Recently, the compound mineral trioxide aggregate (MTA) has gained wide use for pulp capping. One advantage of MTA is its low toxicity. However, the effects of MTA and calcium hydroxide compounds on the toxicities of other dental materials have not been tested. The aim of this study is to determine whether different pulp capping materials can alter the toxicity of composite restoration materials.
