| Research Abstract |
Root canal enlargement and preparation makes the smear layer on the root canal wall. The aim of this study was to evaluate the influence of endodontic irrigation associated with removal of the smear layer. EDTA with ultra sonic or combination of EDTA and NaOCl with ultra sonic was effective in removing the smear layer on permanent teeth. NaOCl with ultra sonic was effective in removing the smear layer on primary teeth. It was suggested that root canal irrigation with ultra sonic was valid for the alkaline diffusion from calcium hydroxide.
