statement of problem: nowadays mineral trioxide aggregate (mta) is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments. investigations have shown similar physical and chemical properties for portland cement and root mta with those described for mta. purpose: the aim of this in vitro study was to evaluate the tissue reaction to implanted mta, portl...

OBJECTIVE There is some concern that root resection may alter the seal of the previously set orthograde material. The aim of this study was to evaluate the apical sealing ability of orthograde mineral trioxide aggregate (MTA) and calcium enriched mixture (CEM) plugs after resection of the roots. MATERIALS AND METHODS The fluid filtration method was carried out on a total of 51 roots in three ...

Perforations might occur due to carious lesions, tooth resorption or they might be iatrogenic during endodontic treatment or in most cases they might occur during post space preparation. CASE REPORT: A 31-year-old female patient presented with a complaint of chronic pain on tooth #30 during last 6 months and sensitive to bite since a few days ago. There was a mild swelling on the gingival tissu...

Inadequate apical seal is the major cause of surgical endodontic failure. The root-end filling material used should prevent egress of potential contaminants into periapical tissue. The purpose of this study was to compare the sealing ability of four root-end filling materials: white mineral trioxide aggregate (MTA), gray MTA, white Portland cement (PC) and gray PC by dye leakage test. Ninety-si...

Mineral trioxide aggregate (MTA) has shown potential as a repair material for perforations. This clinical case demonstrates that when MTA was used as a repair material for root perforation due to invasive cervical resorption, the tooth was well in function for 27 months. Both clinical and radiographic follow-up showed a stable condition without any probing defect, ongoing root resorption, or ap...

INTRODUCTION This study aimed to compare the cytotoxicity of MTA Fillapex, AH-26 and Apatite root canal sealers at different times after mixing. METHODS AND MATERIALS In this in vitro study, MTA Fillapex, AH-26 and Apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. Then, human fetal foreskin fibroblast cell line (HFFF2) were added to each sealer cell culture me...

Aim: The purpose of this study is compare sealing ability of mineral trioxide aggregate (MTA) and Biodentine as root end filling material, and also to compare the effect of different retro preparation techniques i.e. conventional bur v/s ultrasonic tips on sealing ability of both the root end filling materials. Materials and Methods: Totally, 40 extracted human single rooted teeth were decorona...

We described a combined periodontal-endodontic lesion, which was caused by a palatogingival groove and an additional root. An interdisciplinary approach involving endodontic therapy, mineral trioxide aggregate (MTA) filling, root resection, guided tissue regeneration, and papillary reconstruction was used for the case. The tooth presents morphologically and functionally normal except tooth disc...

OBJECTIVE Mineral trioxide aggregate (MTA) has been accepted as an appropriate root-end filling material in endodontic microsurgery because of setting ability in the wet environment. The aim of this study was to assess the bond strength of root-end placed MTA and Biodentine (Septodont, Saint Maur des Fossés, France) in the absence/presence of blood contamination. MATERIALS AND METHODS Forty-e...
