The aim of this study was to develop and to characterize a methacrylate-based root canal sealer containing chlorhexidine (CHX) and α-tricalcium phosphate (α-TCP). Experimental dual cure methacrylate-based sealer was produced containing 0, 2.5, or 5 wt% of CHX and 0, 25, or 50 wt% of α-TCP.

An experimental cement was developed containing 60% glycerol salicylate resin, 10% methyl salicylate, 25% calcium hydroxide and 5% Portland cement. Water sorption and solubility were determined based on mass changes in the samples before and after the immersion in distilled water for 7 days.

- The study aimed to investigate how different amounts of radiopaque fillers, like calcium tungstate, ytterbium trifluoride, and barium sulfate, impact the properties of an epoxy resin sealant used in dentistry.
- Researchers created sealers with varying filler percentages and measured aspects like setting time, flow, and bond strength among other properties.
- Results showed that the type and amount of filler influenced factors such as setting time and radiopacity, but overall bond strength remained consistent across different fillers at the highest concentration.
