Abstract

Aim The aims of this study were to: (i) investigate the effects of Ledermix paste as an intracanal medicament on discolouration of mature teeth, (ii)examine whether the discolouring effects were related to the method of application, and (iii) examine the effects of sunlight upon discolouration of mature teeth. Methodology The root canals of 45 mature extracted human teeth were prepared and filled with either Ledermix paste, calcium hydroxide [Ca(OH)(2)], orsaline. In group i, Ledermix paste was placed apical to the cemento-enameljunction (CEJ), whilst in groups 2 and 3 the paste filled the entire pulp chamber and root canals. In group 4, a Ca(OH)(2) and methyl cellulose pasteand, in group 5, saline (control) were allowed to fill the pulp chamber and the root canals. Group 3 teeth were kept in the dark and the other groupswere exposed to indirect sunlight for 12 weeks. Results After 12 weeks, sunlight exposure had caused dark grey-brown staining of the teeth in the Ledermix groups, but this did not occur when the teeth were kept in the dark. More severe staining was noted when Ledermix paste filled the pulp chamber than when the paste was restricted to below the CEI. Conclusions It was concluded that Ledermix paste may cause discolouration of teeth. Such effects can be minimized if placement of the paste is restricted to below the gingival margin. Clinicians should ensure that Ledermix paste is not left on the walls of access cavities.
