Influence of the use of endo PTC on the periapical seal of root canals / Influência do uso do Endo PTC no selamento marginal apical de canais radiculares

ABSTRACT

Twenty extracted human single-rooted teeth were instrumented with the aid of Endo PTC varying the final flush with either a detergent/antiseptic solution or 1 per cent sodium hypochlorite. The root canals were filled and leakage was evaluated using blue-methylene dye and a stereomicroscope. A final flush with detergent/antiseptic solution resulted in significantly less leakage
