An In Vitro Study Of Ph Changes With Endosequence Bc Root Repair Material Fast Set Putty In Simulated Resorptive Defects

Abstract

One of the challenges to endodontic treatment is external inflammatory root resorption, a destructive process which destroys the radicular portion of the tooth when under pathologic states. Treatment has traditionally been via long-term placement of an intracanal medicament of calcium hydroxide. Calcium hydroxide is antimicrobial, able to dissolve tissue, inhibit resorption and induce hard tissue formation. It has an alkaline pH, which disrupts bacterial cell wall metabolism. Cons to its use include potential for tooth fracture and multiple appointments needed for effect on the resorption process. The purpose of this study was to compare in vitro the effects of intracanal placement of Endosequence BC RRM Fast Set Putty and calcium hydroxide on hydroxol ion diffusion through dentin of teeth with simulated root surface cavities, mimicking external resorptive lesions. The goal was to determine if Endosequence BC RRM Fast Set Putty is a conceivable alternative to calcium hydroxide in cases of external inflammatory resorptive lesions.
