Temperature Change of the Pulpal Floor and Restoration With Preheated Resin Composite (A Randomized Clinical Trial)
Study Details
Study Description
Brief Summary
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

Outcome Measures
Primary Outcome Measures
- pulpal floor temperature and restoration temperature [one year]
evaluation the effect of preheating BIS GMA free resin composite at different temperature on temperature change of pulpal floor and restoration and compare it with BIS GMA containing resin composite All readings were taken with the presence of a rubber dam and recorded in Celsius (°C). Five temperature readings were measured for each tooth; (C0): pulpal floor temperature before beginning the restorative procedure. (C1): pulpal floor temperature during placement of preheated composite. (C2): top composite surface after packing and before curing. (C3): pulpal floor temperature after curing of the preheated composite. (C4): top composite surface after curing. The pulpal floor and the restoration temperature of each tooth was measured by a K-type temperature Probe attached to portable mini type thermometer device
Secondary Outcome Measures
- The effect of different preheating temperatures on restoration temperature and pulpal floor temperature [one year]
Five temperature readings were measured for each tooth; (C0): pulpal floor temperature before beginning the restorative procedure. (C1): pulpal floor temperature during placement of preheated composite. (C2): top composite surface after packing and before curing. (C3): pulpal floor temperature after curing of the preheated composite. (C4): top composite surface after curing. The pulpal floor and the restoration temperature of each tooth was measured by a K-type temperature Probe attached to portable mini type thermometer device
Other Outcome Measures
- The difference in restoration and pulpal floor temperatures before and after curing of preheated resin composite [one year]
Five temperature readings were measured for each tooth; (C0): pulpal floor temperature before beginning the restorative procedure. (C1): pulpal floor temperature during placement of preheated composite. (C2): top composite surface after packing and before curing. (C3): pulpal floor temperature after curing of the preheated composite. (C4): top composite surface after curing. The pulpal floor and the restoration temperature of each tooth was measured by a K-type temperature Probe attached to portable mini type thermometer device
