Abstract
[Objective] The objective of this study was to monitor and compare heat generation in 3 different restorative materials using infrared thermography (IRT). [Methodology] Three restorative materials were prepared (n=6); Fuji I (GI; GC), Unifast III (AR; GC) and Protemp 4 (AC; 3M ESPE), in clear crown former. The 3 groups were real-time imaged under thermal imaging camera (FLIR) from the beginning of the application and up to 4 min. [Results] One-Way ANOVA with least significant difference (LSD) showed a statistically significant difference between the tested groups (p < 0.05). The highest temperature was detected as follows: AR > AC > GI. [Conclusion] It is recommended to limit the fabrication of acrylic based provisional restorations to indirect technique.
