Effect of photodynamic therapy and non-thermal plasma on root canal filling: analysis of adhesion and sealer penetration

J. appl. oral sci; 25 (4), 2017
Abstract Objective The aim of this study was to evaluate the effect of photodynamic therapy (PDT) and non-thermal plasma (NTP) on adhesion and sealer penetration in root canals. Material and Methods Sixty single-rooted premolars were used. The teeth were prepared using a crown-down technique. NaOCl a...

Repair of Bone Defects with Chitosan-Collagen Biomembrane and Scaffold Containing Calcium Aluminate Cement

Braz. dent. j; 28 (3), 2017
Abstract Innovative biomaterials can provide a promising new direction for the treatment of bone defects, stimulating a proper repair process, with no damage to adjacent tissues. The purpose of this in vivo study was to evaluate the biocompatibility and the osteoinductive capacity of chitosan-collagen bi...

Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis

J. appl. oral sci; 25 (2), 2017
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatmen...

Cytotoxicity of New Calcium Aluminate Cement (EndoBinder) Containing Different Radiopacifiers

Braz. dent. j; 28 (1), 2017
Abstract This study aimed to evaluate the cytotoxicity of a calcium aluminate cement (EndoBinder) containing different radiopacifiers, Bi2O3, ZnO or ZrO2, compared with Mineral Trioxide Aggregate (MTA). According to ISO 10993-12:2012 (E) recommendations, 0.2 g of each cement were applied in transwell ins...

Evaluation of sealing ability, color alteration and surface morphology of MTA and Portland cement associated with different radiopacifiers and liquids

This study aimed to analyze the influence of two different vehicles for MTA manipulation on color alteration, chemical characteristics, and radiopacity after immersion in blood or distilled water (DW). In addition, some physical-chemical properties, volumetric solubility and bioactivity of new brands of ...

Physical-chemical properties and cytotoxicity analysis of 5 different endodontic sealers

The aim of this study was to analyze the radiopacity, setting time, flowability, pH, calcium ion release, solubility and cytotoxicity of bioceramic cements Totalfill BC Sealer and Totalfill BC RRM, and compare them with AH Plus, MTA Fillapex and MTA Angelus. The groups were divided and compared among the...

Análise comparativa da adaptação marginal, infiltração microbiana e da citotoxicidade em ápices retrobturados com os cimentos Palacos-R e MTA

O sucesso do tratamento endodôntico está relacionado com uma adequada limpeza, modelagem e um bom selamento do sistema de canais radiculares. A cirurgia parendodôntica é um procedimento que tem como finalidade resolver problemas que não puderam ser solucionados pelo tratamento endodôntico convencio...

BiodentineTM is cytocompatible with human primary osteoblasts

Abstract Calcium silicate-based materials have been widely studied due to their resemblance to, and similar applicability of, mineral trioxide aggregate (MTA). Among these, Biodentine™ (BD) was specifically designed as a "dentin replacement" material for applications such as root perforations, apex...

Interaction of dental pulp stem cells with Biodentine and MTA after exposure to different environments

J. appl. oral sci; 24 (5), 2016
ABSTRACT Objective: The aim of the present study was to evaluate and compare the cytotoxic effects of Biodentine and MTA on dental pulp stem cells (DPSCs) and to assess cell viability and adherence after material exposure to an acidic environment. Material and Methods: DPSCs were cultured either alone ...

Effect of addition of nano-hydroxyapatite on physico-chemical and antibiofilm properties of calcium silicate cements

J. appl. oral sci; 24 (3), 2016
ABSTRACT Objective Mineral Trioxide Aggregate (MTA) is a calcium silicate cement composed of Portland cement (PC) and bismuth oxide. Hydroxyapatite has been incorporated to enhance mechanical and biological properties of dental materials. This study evaluated physicochemical and mechanical properties a...
