Abstract
A new visible-light-curing calcium hydroxide product named “Prisma VLC Dycal” (VLC Dycal) was subjected to study. VLC Dycal is the improved type of “Dycal” which is used generally as the pulp capping agent.
The purpose of this study was to examine the physico-chemical quality as well as the dental pulp reaction towards this agent when it was used as the indirect pulp-capping agent. The acid resistance of VLC Dycal was evaluated by applying 60% phosphoric acid to the agent. The physical property of VLC Dycal was also evaluated by measuring the compressive strength of the agent.
The results obtained were as follows:
1) The compressive strength of VLC Dycal was about ten times greater than that of Dycal.
2) The acid resistance of VLC Dycal was remarkably greater than that of Dycal.
3) The pulp response of VLC Dycal was not inferior to that of Dycal.
