Abstract

Adhesive cementation of ceramic veneers may increase pulpal temperature (PT) due to the combined efect of heat generated by the curing unit and the exothermic reaction of the luting agent (LA). PT increase may induce pulpal damage. The aim was to determine the PT rise during the luting of ceramic veneers (CV) of diferent thicknesses with light- or dual-curing (LC, DC) adhesive cements as well as pre-heated restorative resin-based composites (PH-RBC). For this a thermocouple sensor was positioned in the pulp chamber of a prepared maxillary central incisor. LC, DC adhesive cements and PH-RBCs heated to 55 °C were used for the luting of CVs of 0.3, 0.5, 0.7, and 1.0 mm thicknesses. The exothermic reaction of LAs added signifcantly to the thermal efect of the curing unit. PT change ranged between 8.12 and 14.4 °C with the investigated combinations of LAs and ceramic thicknesses (p≤ 0.01). The increase was inversely proportional to the increasing CV thicknesses. The highest rise (p≤ 0.01) was seen with the polymerization of PH-RBCs. Temperature changes were predominantly infuenced by the composition of the LA, which was followed by CV thickness.
