The sealing ability of orthograde mineral trioxide aggregate (MTA) root canal filling against human saliva was assessed in vitro. Leakage of gray-colored MTA, white-colored MTA and vertically condensed gutta-percha and sealer were compared. Forty-three extracted single-rooted human teeth were serially instrumented to a file size 40/0.06 at the apex and obturated with either gray-colored MTA (gr...

Mineral trioxide aggregate (MTA) has shown potential as a root-end filling material. This clinical case describes the successful treatment of a premolar with an open apex using MTA and the warm gutta-percha technique. The results suggested that MTA may be used as an apical filling material in permanent teeth with multiple canals.

Apical sealing is essential for the success of paraendodontic surgery, so any procedure that may favor an adequate sealing of the apical remainder should be performed. The purpose of this study was to evaluate the influence of diode laser irradiation on the apical sealing of root-end cavities with MTA retrofillings. Root canals in twenty extracted human teeth were shaped with K-files and filled...

GIC, microleakage, Miracle Mix, MTA, root-end filling. Abstract The main objective of a root end filling material is to provide an apical seal that prevents the movement of bacteria and the diffusion of bacterial products from the root canal system into periapical tissues. The aim of this study was to compare the microleakage of three root end filling materials Mineral trioxide aggregate (MTA),...

statement of problem: adhesion to root canal dentin is one of the necessary characteristics of endodontic sealers. mta fillapex (angelus, londria, pr, brazil) is one of the recently introduced mta-based sealer. only a limited number of studies have evaluated the bonding of this sealer to the dentin, with conflicting results. objectives: the purpose of this study was to evaluate the bond strengt...

OBJECTIVE The purpose of this study was to evaluate the sealing ability of castor oil polymer (COP), mineral trioxide aggregate (MTA) and glass ionomer cement (GIC) as root-end filling materials. Forty-five single-rooted human teeth were cleaned and prepared using a step-back technique. The apical third of each root was resected perpendicularly to the long axis direction. All teeth were obturat...

Incisors are the most frequently involved teeth to suffer dental trauma, with root fractures occurring in 3% of injuries due to dental trauma. Horizontal root fractures mostly affect upper central incisors, mainly in the middle third of the root. Nevertheless, apical and coronal third fractures are also sometimes reported. This case report presents the five-year follow-up of a 16-year-old male ...

This in vitro study aims to evaluate the sealing ability of gutta percha root filling used with mineral trioxide aggregate [MTA], and zinc-oxide eugenol as sealer. Thirty freshly extracted single-roote teeth were selected, decoronated and then instrumented. Samples were randomly divided into five experimental groups. In group 1, root canals were filled using single cone gutta percha technique, ...

INTRODUCTION Furcal perforations are one of the most challenging causes of endodontic failures. Several materials including MTA have been used for non surgical repair of these perforations. The aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using Root MTA and ProRoot MTA. MATERIALS AND METHODS This in vitro study was conducted on 54 primar...

MTA is used widely in endodontic treatment as a pulp capping material, root-end filling material, and perforation repair. Although MTA has many favorable properties, long setting time is a clinical disadvantage. To overcome this problem many studies were performed. Hydration accelerators, such as citric acid, lactic acid, calcium chloride, and calcium lactate gluconate, were added during the mi...
