Background: Resin‑ based materials generally require light activation for the polymerization. The present study was conducted to compare the temperature changes of self‑etch and self‑adhesive resin cement during the polymerization process. Materials & Methods: The present study was conducted in the department of Prosthodontics. It comprised of thirty recently extracted non carious human mandibular third molars. Dentin surface was prepared with extracted human mandibular third molars. Adhesive resin cements (Panavia F and Rely X) were applied to the dentin surface and polymerized under IPS e.max Press restoration. Differences between the baseline temperature and temperatures of various time points at 2 minutes, 6 minutes, 10 minutes, and 14 minutes were calculated. Results: Panavia F showed temperature change of 2.16° at 2 minutes, 2.03° at 6 minutes, 1.42° at 10 minutes and 0.86° at 14 minutes. Rely X showed temperature change of 1.72° at 2 minutes, 1.10° at 6 minutes, 0.58° at 10 minute and 0.24° at 14 minutes. The difference was significant (P< 0.05). Conclusion: Authors found that Panavia F showed maximum temperature change than Rely X recorded at 2 minutes, 6 minutes, 10 minutes and 14 minutes. There was significant difference between two adhesive resins.
Key words: Adhesive resin cements, Polymerization, Temperature.
