Aim: Aim of this study was to assess the thermal changes within the pulp at the time of polymerization of three different adhesive resin materials.
Materials and methods: Sixty human premolar teeth that had been recently extracted for orthodontic reasons and were devoid of dental caries/flaws were included in this research. Following preparation of the cavities, all 60 samples consisting of 20 premolars in every group, depending on the adhesive resins that were positioned as were assigned at random to one of the following three groups: Group I: RelyX self-adhesive resin cement; Group II: Breeze self-adhesive resin cement; Group III: Pan F self-etch adhesive resin cement. The temperature changes were calculated using a thermocouple wire attached to a digital thermometer. The dissimilarities amid the baseline temperature as well as the temperatures at different time intervals (1, 5, 10, and 15 minutes) were established.
Results: The thermal value was higher at first minute (1.84 ± 0.34) and gradually reduced at 5 minutes (1.36 ± 0.29), 10 minutes (0.62 ± 0.11), and 15 minutes (0.06 ± 0.03) in RelyX self-adhesive resin cement. The maximum thermal value was found at the first minute (2.66 ± 0.21) and gradually reduced at 5 minutes (1.42 ± 0.13), 10 minutes (0.86 ± 0.09), and 15 minutes (0.28 ± 0.01) in Breeze self-adhesive resin cement. The higher thermal value was found at the first minute (1.98 ± 0.19) and gradually reduced at 5 minutes (1.49 ± 0.14), 10 minutes (0.76 ± 0.10), and 15 minutes (0.16 ± 0.09) in Pan F self-etch adhesive resin cement and there was a statistically significant difference found between various time points and with all three adhesive resin material groups (p <0.001).
Conclusion: This current research arrived at a conclusion that each of the three adhesive resin substances showed a safe temperature change within the pulp. However, the lowest heat scores within the pulp were depicted by RelyX self-adhesive resin in pursuit by Pan F self-etch adhesive resin cement as well as the Breeze self-adhesive resin cement in that order.
Clinical significance: The clinical triumph of a restoration is dependent partially on the method of cementation, which is utilized to establish a connection amid the restoration and the tooth. Temporary and permanent pulp inflammation can be avoided by the decreased temperature changes in the adhesive resin cement at the time of polymerization.
