“…This result was in agreement with the findings of Fanibunda and De Sa 18) who reported significantly higher temperature rise with abnormal dentin specimen. To date, temperature rise when using compomers was measured only in one study 5) in published literature. Al-Qudah et al 5) suggested that the resin content of dental materials was one important factor that affected temperature rise.…”

“…To date, temperature rise when using compomers was measured only in one study 5) in published literature. Al-Qudah et al 5) suggested that the resin content of dental materials was one important factor that affected temperature rise. The higher the resin filler content of a dental material, the lower was the temperature rise, and therefore a lower proportion of resin available for polymerization.…”

“…Therefore, a considerable fraction of the energy which might otherwise raise the matrix temperature is absorbed by the filler. In this thermal context, the filler is an active phase playing a moderate role 3,5) . In the present study, both the restorative materials used had a high filler content (77％ by weight for Compoglass and 84％ by weight for Aelite LS) and they induced a similar temperature rise (p>0.005).…”

“…The classic animal study by Zach and Cohen set forth a threshold temperature for irreversible pulpal damage when external heat was applied to a sound tooth: a 5.5℃ intrapulpal temperature increase induced necrosis in 15％ of the tested pulps 4) . Many laboratory studies have been conducted on ground or non-carious dentin substrates to measure temperature rise during photopolymerization of resin-containing dental materials [5][6][7][8] .

Temperature Rise under Normal and Caries-Affected Primary Tooth Dentin Disks during Polymerization of Adhesives and Resin-containing Dental Materials

et al. 2008

The purpose of this study was to compare the temperature rise under normal and caries-affected primary tooth dentin during photopolymerization of two adhesives and resin-containing restorative materials. Caries-affected and normal dentin disks were prepared from extracted primary molars with only mesial or distal approximal caries (4 mm in diameter, 1 mm in height). Temperature rise during photopolymerization of adhesive materials was measured with a J-type thermocouple wire that was connected to a data logger. Data were analyzed with two-way ANOVA and independent samples t-test. Temperature rise under caries-affected primary tooth dentin disks was higher than that of normal primary tooth dentin disks during polymerization of both adhesive systems and resin-containing dental materials (p<0.05). It was found that adhesive systems induced a higher temperature rise during polymerization as compared to the resin-containing restorative materials (p<0.05). In particular, temperature rise during polymerization of adhesive materials exceeded 5.5℃ under caries-affected primary tooth dentin.
