Abstract


The most widely used intracanal medicament is calcium hydroxide (Ca(OH2). However, the residue of
Ca(OH)2 in the root canal must be removed prior to obturation. The residue of Ca(OH)2 in the root canal
walls would result in apical leakage. This is due to the unstable dimension of Ca(OH)2, reduced flow
and 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 the
residue 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 teeth
were 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. The
specimens 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 sectioned
in the sagittal direction, then was photographed under a stereo microscope at 120x magnification. The
percentages of Ca(OH)2 residue were calculated using UTHSCSA image tool 3 software. Data were
analyzed using T-test at 95% level of significance.
The results revealed that the group of Ca(OH)2+ chlorhexidine digluconate 2% paste showed the
lowest number of residual Ca(OH)2.The conclusion of this study was that the vehicles affected the total
residue of Ca(OH)2.
