“…The higher temperature increase observed in the SDR group seems to be related to its low filler content. Previous studies have reported that the exothermic reaction of the resinbased materials during polymerization is proportional to the amount of filler present in the resins 24,36,40) . Consistent with the reports, the temperature changes in SDR and Filtek Bulk Fill Posterior were higher than Z250 (control group) which was placed incrementally.…”

“…Briefly, all of these also indicate that the differences of setting reaction and material compositions are important factors inducing the intrapulpal temperature rise 15,24,33) . In previous studies, the temperature increase during the curing of different restorative materials has been measured with a calorimeter 41) , differential thermal analysis 42) , infrared cameras 40) , and thermocouples. In the current study, the thermocouple device, described as a confidential method in previous studies [28][29][30] , was selected to determine the temperature changes.…”

The aim of this study was to evaluate the intrapulpal temperature changes during the curing of different bulk-fill restorative materials. Ten mandibular molar teeth were selected and occlusal surfaces were removed to obtain a standard 0.5 mm occlusal dentin thickness. Five bulk-fill restorative materials and a conventional resin composite (control) were applied. The intrapulpal temperature changes during the curing of these materials were determined by a device simulating pulpal blood microcirculation. The difference between the initial and maximum temperature values (Δt), was recorded. The data were statistically analyzed with one-way ANOVA and Tukey's HSD test (p<0.05). There were statistically significant differences between materials (p<0.001). The light-curing bulkfill restoratives exhibited the highest Δt values. Equia Forte showed the lowest Δt values among all the groups (p<0.05). Bulk-fill restorative materials causes significantly different temperature changes in the pulp chamber according to curing type. Therefore, clinicians should be considered when using these materials.

“…A number of additional factors, such as light intensity of the LCU, thickness of the remaining dentin, composition of the restorative materials, distance between the LCU and the material surface, position of LCU, and exposure time, 13,14,15 can also affect the temperature of the pulp cavity during polymerization. This study aimed to determine the effects that the processes associated with the application of a new filling product, GCP, had on the intrapulpal temperature, and to assess whether different dentin thicknesses affected this in any way.…”

Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study Abstract: This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm dentin thickness was prepared in the extracted human molar teeth. RGI and GCP fills were placed in the cavities and cured with two different light-curing units. This study included a total of 120 samples, with 20 samples in each group. The pulp microcirculation method was used for measuring the intrapulpal temperature changes. Statistical analysis was performed using the two-way ANOVA and Tukey HSD multiple comparison tests. Statistically significant differences were observed between 1 mm and 2 mm dentin thicknesses (p < 0.001). The GCP groups (both 1 mm and 2 mm dentin thicknesses) exhibited higher temperatures than the other groups (p < 0.001), and Fuji II LC and Photac Fil Quick Aplicap showed similar values (p > 0.05). The highest temperature changes were observed with 1 mm dentin thickness. While RGI materials in both dentin thicknesses did not cause temperature changes that were harmful to the pulp, GCP CarboLED LCU caused the highest intrapulpal temperature rise, and these values were borderline harmful to the dental pulp.

“…The increase in pulpal temperature has been attributed to two main sources: radiation energy emittedbytheLCUandthepolymerizationexotherm of resin composites 2,4,16,17,20,22,23) . It has been reported that photopolymerization with high energy output curing units caused significantly higher pulp chamber temperaturechangesascomparedtotheconventional curingunits 16,19,[24][25][26] .…”
