Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Lecture / Presentation Description
Objectives: Compare heat-generation of various multi-peak-LCUs with single-peak-LCU at the pulpal-wall(PW) of deep cavities when curing bulk-fill-resin-composites(BFRC) containing Ivocerin photoinitiator. Background: Multi-peak light-curing-units(LCU) are gaining popularity due to potential depth-of-cure concerns with single-peak LCUs, especially with photoinitiator alternatives used in (BFRC). However, there is limited data on their heat-generation.Methods: Single extracted/sound human-molar was used for standardized set-up. Box cavity(3.5x2.5x3mm,0.5mm remaining-dentin-thickness) was prepared on buccal-surface for BFRC placement, access window was opened from the opposite lingual-surface to expose PW of the pulp-chamber. PW was reflected to an infrared thermal-camera(Thermovision-A320,FLIR) via minimal-energy-loss-mirror(NT99-456,Edmund) to measure transferred-heat from LCUs through dentin. Three multi-peak LCUs(Bluephase-PowerCure/IvoclarVivadent, Valo/Ultradent, D-Light-Pro/GC) were compared to one single-peak LCU(Demi Ultra/Kerr) when curing BFRC(Tetric-EvoCeram Bulk-Fill/IvoclarVivadent,IVA-shade,3mm). Restorations were placed with no bonding agent for easy BFRC removal after each curing. PW temperatures during full-curing-cycle(10sec.) were recorded in four LCU groups(n=10). Baseline-to-maximum temperatures(ΔT) were measured (Thermavision ExaminIR) and statistically analyzed using One-way ANOVA and Tukey’s post-hoc tests.Results: There were statistically significant differences among LCU groups in ΔT(F(9,90)=154.9, ppConclusions: Data showed no significant difference in multi-peak versus single-peak LCUs to claim that heat generation of one is superior than other. Single-peak LCU came in second lowest and was between various multi-peak LCUs. Further studies are necessary using body-temperature as baseline.
