The in vitro antibacterial activity of K-20 prepared by addition of chlorhexidine dihydrochloride to a base sealer was compared with that of a manufactured product. The acute toxicity of K-20 was also investigated in the animals. The results demonstrated that K-20 prevents bacterial propagation without an unfavorable influence on the living tissue. K-20 was also evaluated clinically in cases of...

Pulpal and periradicular pathosis are the result of microbial, mechanical, or chemical invasion. Microorganisms are the main irritants of pulpal and periapical tissues. The goal of the obturation is to obtain a fluid-tight seal of the root canal system from its coronal aspect through its apical extent to preserve from the irritants.. Root apices have morphological irregularities in teeth with p...

A mandibular fi rst molar with two distal roots is an interesting example of anatomic variation. This paper describes case reports of mandibular fi rst molar with three roots (one mesial and two distal) and four canals (two in mesial and one in each distobuccal and distolingual root). The canals were shaped with protaper rotary fi les and irrigated with 5.25% sodium hyochlorite, 0.2 %w/v of chl...

The aim of the present study was to compare sealing abilities of Resilon/Epiphany (R/E) with those of guttapercha and Kerr Pulp Canal Sealer EWT (GP/PCS). 50 single rooted teeth were randomly divided into 2 groups (n = 22) (R/E; GP/PCS), and 2 control groups (n = 3) (Positive, Negative). Fluid flow rate through the filled roots was measured using a fluid filtration device. The same specimens we...
