Influence of calcium hydroxide dressing and two irrigants on the filling of artificial lateral canals.

Context: This study was carried out on the assumption that calcium hydroxide [Ca(OH) 2 ] dressing and irrigants may influence the obturation of lateral canals.

Aims: To evaluate the influence of 2.5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) gel and Ca(OH) 2 on the filling of artificial lateral canals.
