Effect of Intraorifice Depth on the Sealing Ability of Inraorifice Sealing Agent – An in Vitro Study.

Abstract

Aim:The present study was conducted to evaluate the effect of intraorifice depth on the sealing ability of intraorifice sealing agent using methylene blue as a dye tracer. Material And Method: Twenty extracted premolars were decoronated , cleaned and shaped and obturated with guttapercha points and following which guttapercha was removed from each group at varying depths of 1mm, 2mm and 3mm respectively and these empty canal space were then filled with light cure glass ionomer cement as intraorifice sealing agent and then the microleakage was measured in each group by assessing the amount of dye penetration using a stereomicroscope by using methylene blue as the dye tracer after the specimens were sectioned longitudinally.
