Type 1 diabetes mellitus (T1DM) is the result of the autoimmune response against pancreatic insulin producing cells. This autoimmune response begins months or even years before the first presentation of signs and symptoms ...

Purpose: To evaluate the cytotoxic effects of different concentrations of Chlorhexidine (Chx) to the odontoblast cell line MDPC-23. Methods: The odontoblast-like cells were seeded (30,000 cells/cm 2) in 60 wells of 24-well ...
