Antifungal Denture Base Resin

The denture base resin is prone to candidal infection and leads to denture stomatitis. Recently it was found that phosphated methyl methacrylate dramatically reduces the colonization of candida on the denture. This will prove to be a great relief for denture wearers.

Which endodontic sealer shows highest bacterial leakage ?

A study tested six different endodontic sealers. AH Plus, Sealer 26, Epiphany SE, Sealapex, Active GP, Endofill, and two MTA-based sealers - Endo CPM Sealer and MTA Sealer.
Among all of them, MTA based sealers show the highest bacterial leakage as compared to other non MTA based sealers.
