Abstract : Context: Eugenol-based cements are used for temporization; however, they affect the physical properties of resin cements. Aim: To evaluate effect of eugenol and non-eugenol-containing temporary cements on the tensile bond strength of self-adhesive dual-cure resin cement (SARC) at intervals of 24 hours, 7 days, and 14 days. Settings and design: Preclinical in vitro material study. Materials and methods: A total of 105 freshly extracted, intact, maxillary premolars were divided into seven groups consisting of 15 teeth each followed by preparation to receive cast metal crowns. They were temporized using eugenol cement in groups II, III, and IV, non-eugenol cement in groups V, VI, and VII, and stored in distilled water for specific periods. Provisional cement was removed using ultrasonic scaler and cleaned with pumice-water slurry. Thereafter, the cast crowns were cemented using SARC.46 The tensile bond strength of SARC in the respective groups were tested on the universal testing machine using “Crown pull test” at a cross-head speed of 0.5 mm/min until failure. Results: Results were analyzed using analysis of variance (ANOVA) and Tukey’s post hoc test. After 24 hours, significant reduction in the bond strength was observed in both eugenol and non-eugenol groups. After 7 and 14 days, the reduction in the bond strength was insignificant. No significant differences were found in the bond strengths of SARC among eugenol and non-eugenol groups. Conclusion: The study showed that waiting for a week before performing cementation with SARC when using eugenol or non-eugenol provisional cements displayed favorable results.
