To investigate the temperature changes in the primary teeth pulp chambers during the curing of different colored compomers Materials and Methods: Class II cavities were prepared in primary mandibular second molars (n=5). Gold, blue, green, berry, and tooth (control group) colored compomers were tested in two steps (aproximal and occlusal). Measurement of pulp chamber temperature changes during curing was performed with a J type thermocouple. The data including differences between the highest and initial temperature values were recorded and analyzed by two-way ANOVA and Mann-Whitney U tests Results: There were statistically significant differences temperature changes in groups (p<0.05). Cümle yeniden kurulabilir. Gold colored compomer Demonstrate the highest temperature increase in both proximal and occlusal surfaces. Tooth colored compomer (A2) Demonstrate the lower temperature increase. The temperature increase in aproximal cavities was found higher than the temperature increase in occlusal cavities. Conclusions: Colored compomer can be an alternative restorative materials in superficial class I and II cavities in primary teeth. Dark coloured compomers should be used in deep cavities.

In recent years, observing the advances in nano-technology, many attempts have been made in using nano-particles in nanoclay resin to improve thermal conductivity, and some success has already been achieved. In this study, the thermal properties and experimental results of a composite wall made of Glass / Carbon / Glass layers with nanoclay epoxy resin in between thereof in different ratios (0.5%, 0.75% and 1.25% by volume) were obtained and with plain sample compared. For this purpose, TG, DSC analyzes and heat conduction tests of prepared samples were performed. Experimental results show that its thermal conductivity is increased by about 7.88 % with the 0.75% wt addition of nanoclay. In addition, TG analysis results showed that the lowest mass loss was observed in the samples with 0.75% nanoclay with a value of approximately 18.32%. In the DSC results, the highest glass transition temperature of 433 °C and the highest crystallization temperature of 553 °C were observed in the 1.25% nanoclay added samples.

Objective:The current study investigated the thermal conductivity of dimethacrylate-and silorane-based composite resins at different polymerization times and modes. Materials and Method:Forty dentin discs (8 mm diameter, 1.5 mm thick) were obtained from caries-free human molar teeth. Filtek Silorane (3M ESPE, Minnesota, USA) and Filtek Z550 (3M ESPE, Minnesota, USA) composite were polymerized with a LED (Light-Emitting-Diode) curing device (Valo, Ultradent Products Inc., Utah, USA), in two modes in different times (xtra power mode, 3200 mW/cm 2 ; 3-, 6-, 9-, 12-, +2 s / standard mode 1000 mW/cm 2 , 10-, 20-, 30-, 40-, +2 s)(n=10). Temperature changes in the dentin discs were measured with a K-type thermocouple (E-680, Elimko Co., Ankara, Turkey) and recorded.Data were statistically analyzed using Analysis of variance and independent sample t test (α=0.05) Results: Mean temperature changes were significantly different among polymerization times and modes (p<0.05). Temperature change of Filtek Silorane were significantly higher thanFiltek Z550 for each time interval and curing mode (p<0.05). Conclusion:As the polymerization time increases, the temperature increase in the dentin may adversely affect to the pulp health.
