introduction: this study aimed to compare the marginal adaptation of new bioceramic materials, endosequence root repair material (errm putty and errm paste), to that of mineral trioxide aggregate (mta) as root-end filling materials. materials and methods: thirty-six extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah-26 sealer. the roots were resected 3 mm f...

Background. Maximum sealing ability or adhesion of endodontic sealers can be achieved after effective removal of the smear layer. Endodontic irrigants assist in adequate removal of the smear layer, improving the retention mechanism. The aim of this study was to evaluate the effect of two different root canal irrigation solutions (5.25% NaOCl followed by 17% EDTA and QMix) on the apical sealing ...

Capík I., S. Štvrtina: Comparison of Gutta-Percha Obturation Techniques in the Treatment of Wide Root Canals in Dogs. Acta Vet. Brno 2008, 77: 291-296. An in vitro study was conducted to compare gutta-percha obturation techniques of the developing incisors in dogs. Two perpendicular radiographic views were used for evaluation of apical and overall appearance of root canal obturation. Apical lea...

This case report describes intratubular biomineralization in root canal, filled with calcium-enriched material after 8 years of clinical maintenance. The schematic findings of dentinal tubules were investigated with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The root canal obturation material was closely adapted to root dentin surface, suggesting the possibilit...

invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. this report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper rig...

The aim of this paper is to show and asses the clinical applications of the Mineral Trioxide Aggregate (MTA) in pediatric dentistry, either on primary teeth or on immature apex permanent teeth. We have described the primary tooth pulpotomy technique using MTA, that is characterized by a superior biocompatibility and a sealing ability that make it a more suitable compound compared to other mater...

OBJECTIVES A variety of root canal sealers were recently launched to the market. This study evaluated physicochemical properties, biocompatibility, and sealing ability of a newly launched resin-based sealer (Dia-Proseal, Diadent) compared to the existing root canal sealers (AHplus, Dentsply DeTrey and ADseal, Metabiomed). MATERIALS AND METHODS The physicochemical properties of the tested seal...

Apicoectomy failure is generally related to inappropriate marginal sealing of the retrocavity, which allows percolation of microorganisms and their products from root canal system to periapex. This study evaluated tubular penetration of canal sealers and marginal permeability after retrocavity irradiation with Er;Cr:YSGG laser and retrofilling with MTA or cyanoacrylate. Twenty-two single-rooted...

There were several materials used to seal different types of perforation defects. MTA is one of these restorative materials that is considered the most effective, biocompatible, non-toxic, and non-irritant; promote bone healing and cementum regeneration. The objective of this article was to review and summarize the sealing ability of MTA compared with the other materials used for sealing differ...
