ABSTRACT

The prime purpose of the cleaning shaping procedures is to manage intracanal infection by achieving a significant reduction in the intracanal bacterial load and infected dentin. Disinfection of the root canal is tedious goal therefore association of the mechanical preparation with irrigation solutions and intracanal medicaments was proposed to reduce the infection of root canal. Aim and objective: To investigate the influence of the remaining volume of different intracanal medicaments on the bond strength of bioactive glass sealer. Materials and Methods: 45 single rooted premolars were standardized and prepared using rotary files. The specimens were then randomly divided into three groups (n = 15) based on the intracanal medicaments used as follows: Group 1 -Bio c temp ;Group 2 -Metapex ;Group 3 - Calcium hydroxide After 1 week, rinsing of the medicaments was done and the samples were obturated with gutta percha/bioactive glass sealer. Each roots were sectioned and 3 slices of dentin 1 mm thick were obtained from each root third. And the push-out bond strength were evaluated using universal testing machine. Results: Bioactive glass sealer showed higher bond strength with the prior placement of bio-c temp medicament when compared to the other groups. Disscussion: some medicaments may alter dentin surface properties, thereby enhancing or reducing bond strength, which directly affect the long term sealing ability and success of endodontic treatment. Conclusion: Bio-c temp proved to be better intracanal medicament than other tested groups in terms of the push out bond strength of the sealer.
