The most widely used intracanal medicament is calcium hydroxide (Ca(OH2). However, the residue ofCa(OH)2 in the root canal must be removed prior to obturation. The residue of Ca(OH)2 in the root canalwalls would result in apical leakage. This is due to the unstable dimension of Ca(OH)2, reduced flowand working time of the sealers, and decreased adhesion of sealers and gutta percha to root canal walls.This study aimed to determine the effect of Ca(OH)2 vehicles and agitation irrigation techniques on theresidue of Ca(OH)2 in the apical third of the root canal walls.Twelve extracted mandibular first premolars were used in this study. The crowns of the teethwere removed at the apical part of cemento enamel junction with a length of 14 mm from the apical.The canals were prepared with a Step Back technique to obtain Master Apical File ( MAF ) # 40. Thespecimens were randomly devided into groups I, the pastes of Ca(OH)2+chlorhexidine digluconate 2%.In groups II, the pastes of Ca (OH)2+ glycerin were applied. Each specimen of the study was sectionedin the sagittal direction, then was photographed under a stereo microscope at 120x magnification. Thepercentages of Ca(OH)2 residue were calculated using UTHSCSA image tool 3 software. Data wereanalyzed using T-test at 95% level of significance.The results revealed that the group of Ca(OH)2+ chlorhexidine digluconate 2% paste showed thelowest number of residual Ca(OH)2.The conclusion of this study was that the vehicles affected the totalresidue of Ca(OH)2.

The purpose of this study was to evaluate the surface tension of calcium hydroxide (CH) associated with different substances (deionized distilled water, camphorated paramonochlorophenol, 2% chlorhexidine digluconate, Otosporin, 3% sodium lauryl ether sulphate; Furacin, PMC Furacin) using tensiometer. The action of the substances studied on the dentinal structure enhances the property of surface tension. This method consists in the application of force to separate a platinum ring immersed in the substances. Thus, torsion was applied to the screw until the platinum ring separated during substances testing. Considering the methodology applied, the following can be concluded: distilled water alone or associated with CH presented a high surface tension (70.00 and 68.40 dynes/cm); calcium hydroxide in association with anionic detergent showed low surface tension (31.60 dynes/cm); camphorated paramonochlorophenol plus CH presented low surface tension (37.50 dynes/cm); 2% chlorhexidine associated with calcium hydroxide showed high surface tension values (58.00 dynes/cm); Otosporin plus calcium hydroxide showed low surface tension (35.40 dynes/cm); paramonochlorophenol Furacin mixed with calcium hydroxide presented surface tension equal to 45.50 dynes/cm; sodium hypochlorite presented high surface tension (75.00 dynes/cm). Antimicrobial agents more indicated in endodontics, i.e. CH, chlorhexidine and hypochlorite, presented the highest surface tension.
