| الوصف: | Aim: The aim of the present study is to assess the microhardness of resin-based composites (RBCs) cured with ultrafast curing mode at two different exposure durations. Study Design: This is an experimental in-vitro study. Forty-five cylindrical composite specimens were prepared to a dimension of 5 mm height and 4 mm diameter. Curing was done using three different exposure modes and duration with dual mode LED curing light as follows: Group I: Ultrafast curing mode for 1 second at 2300 mW/cm2 (n = 15); Group II: Ultrafast curing mode for 3 second at 2300 mW/cm2 (n = 15) and Group III: Standard exposure mode for 20 second at 1000 mW/cm2 (n = 15). Vicker’s microhardness measurement was done on both the curing and non-curing sides of the specimen using a motorised diamond-faced micro-indenter (Wilson Wolpwert, Germany) using a load of 50 gram and a dwell time of 30 second. Statistical Analysis: Kruskal Wallis ANOVA was used to test for difference between the three groups followed by Mann–Whitney U test for post-hoc analysis. Results: The microhardness values of the composite cured with a conventional curing unit were significantly higher than the ultrafast cured specimens. Conclusion: Low-intensity conventional curing lights were found to perform better than the high-intensity ultrafast curing units. |
