About

clinical evaluation of the effect of preheating BIS-GMA free resin composite at different temperatures on temperature change of the pulpal floor and restorations and compare it with BIS-GMA containing resin composite.

Hypothesis: Could the preheated composite affect the temperature of the pulpal floor
