TI  - Temperature increases in primary teeth pulp chamber during polymerization of glass ionomer-based restorative materials
AB  - PurposeTo evaluate the temperature changes in primary teeth pulp chambers of differentdentin thicknesses during polymerization of four glass ionomer-based restorativematerials.Materials and MethodsEighty extracted, caries‑free, primary molars were prepared as standardized ClassI occlusal cavities with dentin thicknesses of 1 mm and 2 mm. Four glass ionomerbasedrestorative materials, Dyract XP, Photac Fil Quick Aplicap, Fuji II LC, andGCP Glass Fill, were placed in the cavities and cured with two light-curing units.Temperature increases (initial temperature, 37°C) in the pulp chamber duringpolymerization were recorded by a J-type thermocouple in a pulpal microcirculationset-up. The data were analyzed with Variance analyses and Tukey tests.ResultsThe temperatures recorded in samples with dentin thicknesses of 1 mm and 2mm exhibited statistically significant differences (p<0.05). The GCP Glass Fill groupexhibited the highest temperature increases for both dentin thicknesses (p<0.05).The other groups were not statistically different but the Dyract XP group exhibitedthe least temperature change.ConclusionThe highest temperature changes were observed for 1 mm dentin thickness. Alltemperature increases during polymerizations and setting reactions were lowerthan the corresponding critical values 5.5°C.
