Popis: | Aims: The current in vitro analysis evaluated the depth of cure in newer bulk fill composite resin which compared the traditionally used hybrid and microfill composite resin which used two different light sources quartz-tungsten-halogen (QTH) and light emitting diode (LED) unit with three varying intensities in conventional standard curing mode for 20 s. Materials and Methods: Three composite resins were selected for this study, namely, bulk fill (Smart Dentin Replacement, Dentsply), hybrid (Tetric N – Ceram, Ivoclar), and microfill (Te-Econom Plus, Ivoclar) with four different thickness 2, 4, 6, and 10 cured with varying intensities (625, 850, and 1025 mW/cm2) using two different light sources QTH (QHL 75, Dentsply) and LED (Ledition, Ivoclar and Valo, Ultradent). The depth of cure was determined using a scraping method based on ISO 4049:2000. Statistical Analysis Used: Data were analyzed using Kolmogorov–Smirnov test, Kruskal–Wallis test is applied followed by Bonferroni-corrected Mann–Whitney test. Results: Best depth of cure results were obtained with a bulk fill composite resin cured under 1025 mW/cm2 intensity using LED. Bulk fill showed the highest curing depth results in all varied intensities. Conclusions: Bulk fill composite resin was found to be more successful than hybrid and microfill composite resin with respect to the depth of cure. |
