OBJECTIVE The aim of this in vitro study was to evaluate the degradation of type I collagen fibers after treatment with a papain-based gel associated with a blue dye (PapaMBlue™) for use in antimicrobial photodynamic therapy. MATERIALS AND METHODS For such, 60 bioabsorbable membrane sponge discs were used. Group 1 was the negative control group. In groups(More)
BACKGROUND The elimination of pathogenic microorganisms from the root canal system is one of the major steps required for successful endodontic treatment. The aim of the proposed study is to conduct a randomized, controlled, clinical trial for the clinical and radiographic evaluation of the effectiveness of photodynamic therapy during the endodontic(More)

My purpose was to find out whether changes in serum protein content (albumin and gamma globulin) influenced erythrocyte uptake of glycosides and the capacity of erythrocytes to equilibrate glycoside levels when there are changes in protein binding. Heparinized human blood was incubated with 3H-digoxin, 6 ng/ml, and 3H-digitoxin, 44 ng/ml for 15 min. After(More)
