OBJECTIVE This study evaluated the response of periapical tissues to the endodontic sealer Endométhasone in root canal fillings short of or beyond the apical foramen. MATERIAL AND METHODS Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file and the apical cemental barrier was pe...

BACKGROUND Regardless of the technique and the material used, the goal of obturation remained the same that is to seal every portal of exit in the root canal system. It's not only the apical openings that need to be sealed but also lateral openings, coronal access opening and perforations if they exist failure of the adhesive root canal sealer has led to the idea of usage of dentin bonding agen...

The aim of this study was to asses the calcium release and pH of three root canal sealers. pH and calcium release of three root canal sealers Apexit, Sealapex and Vitapex, were assessed at 30 and 60 min, and 7 days after spatulation. After manipulation, the sealers were placed in tubes and immersed in sealed glass flasks containing 10ml of deionized water and stored at 37°C. Tubes were removed ...

INTRODUCTION An ideal endodontic sealer should adhere firmly both to dentin and to gutta-percha. OBJECTIVE The aim of this study was to evaluate the adhesion of the root canal filling to dentin and gutta-percha using scanning electronic microscopy (SEM). METHODS The sealing ability of endodontic sealers to dentinal walls of the root canal was assessed in recently extracted human single cana...

AIM The aim of this study was to evaluate the inflammatory response to MTA Fillapex, AH Plus, and Pulp Canal Sealer Extensive Work Time (EWT), in a murine bone defect grafting model. MATERIALS AND METHODS Bilateral mandibular critical defects were produced in 45 Wistar rats with a trephine bur#2 and filled with the endodontic sealers. After 7, 14, and 28 days, the rats were euthanized and the...

OBJECTIVES To investigate the bond strength and seal ability produced by AH Plus/gutta-percha, EndoREZ and RealSeal systems to root canal dentin. MATERIAL AND METHODS Sixty extracted single-root human teeth, instrumented manually to size 40, were divided into three groups (n=20) according to the sealer used; G1: AH Plus, G2: EndoREZ, and G3: RealSeal sealers. After filling using the lateral c...

The purpose of this study was to compare the sealing ability of gutta-percha and AH Plus sealer versus Resilon and Epiphany Resin Root Canal sealer using three different final irrigants with the fluid filtration model. There were 140 teeth prepared using a crown-down method to a size 50 file. The teeth were randomly divided into two groups: (A) GP and AH Plus and (B) Resilon and Epiphany. After...

To examine the appearance of root canal walls after retreatment, 80 extracted teeth were chemomechanically prepared using a stepback flare technique and obturated with gutta-percha and either Roth's 801 or AH26 sealers. Four techniques were used to remove gutta-percha and sealer: method 1--heat and files; method 2--heat, files, and CaviEndo; method 3--chloroform and files; and method 4--chlorof...
