The effect of preheating of the silorane-based resin composite on intrapulpal temperature (IPT) and dentin microtensile bond strength (lTBS) was evaluated. For the IPT, teeth (n = 15) were sectioned to obtain discs of mm thickness (2 discs/tooth). The discs were divided into three groups (n = 10/group) according to the temperature of the Filtek LS silorane-based resin composite during its placement, either at room temperature (23 ± 1 C) or preheated to 54 C or 68 C using a commercial Calset device. Discs were subjected to a simulated intrapulpal pressure (IPP) and placed inside a specially constructed incubator adjusted at 37 C. | Effect of preheating of low shrinking resin composite on intrapulpal temperature and microtensile bond strength to dentin
