Surface and vertical dimensional changes of mineral trioxide aggregate and biodentine in different environmental conditions

J. appl. oral sci; 27 (), 2019
Abstract Surface changes in biological environments are critical for the evaluation of physical and biological activity of biomaterials. Objective: This study investigated surface alterations of calcium silicate-based cements after exposure to different environments. Material and Methods: Forty-eight cyl...

A randomized clinical trial of cavity liners after selective caries removal: one-year follow-up

J. appl. oral sci; 27 (), 2019
Abstract Alternatives for the treatment of caries disease, such as minimally invasive approaches, have been developed in recent years. Objective: To carry out clinical and radiographic evaluations of three cavity liners after selective caries removal. Methodology: Thirty-six primary molars with deep oc...

Initial inflammatory response after the pulpotomy of rat molars with MTA or ferric sulfate

J. appl. oral sci; 27 (), 2019
Abstract Purpose To compare, both qualitatively and quantitatively, the inflammatory cells, vascular density and IL-6 immunolabeled cells present in the pulp after pulpotomy with white MTA versus 15.5% ferric sulfate (FS). Methodology Forty-eight mandibular first molars from 24 Wistar rats were divid...

Alternative to avoid tooth discoloration after regenerative endodontic procedure: a systematic review

Braz. dent. j; 29 (5), 2018
Abstract This systematic review aimed to evaluate whether alternative materials to conventional triple antibiotic paste (TAP - metronidazole, ciprofloxacin, and minocycline) and grey mineral trioxide aggregate (GMTA) could avoid tooth discoloration in teeth submitted to Regenerative Endodontic Procedure ...

Ytterbium oxide as radiopacifier of calcium silicate-based cements. physicochemical and biological properties

Braz. dent. j; 29 (5), 2018
Abstract This study evaluated physicochemical properties, cytotoxicity and bioactivity of MTA Angelus (MTA), calcium silicate-based cement (CSC) and CSC with 30% Ytterbium oxide (CSC/Yb2O3). Setting time was evaluated using Gilmore needles. Compressive strength was evaluated in a mechanical machine. Radi...

Clinical, radiographic and histological evaluation of primary teeth pulpotomy using mta and ferric sulfate

Braz. dent. j; 29 (2), 2018
Abstract The aim of this study was to evaluate the clinical, radiographic and histological outcomes of the dentin-pulp complex from primary molars after pulpotomy with mineral trioxide aggregate (MTA) and 15.5% ferric sulfate (FS). Thirty-one primary molars were randomly allocated into MTA or FS groups. ...

Bond strength of experimental root canal sealers based on mta and butyl ethylene glycol disalicylate

Braz. dent. j; 29 (2), 2018
Abstract This study investigated the bond strength of two experimental root canal sealers based on MTA and butyl ethylene glycol disalicylate: MTAe and MTAe-HA. The reference materials used for comparison were AH Plus and MTA Fillapex. Twenty human upper incisors were selected and one 1 mm slice was obta...

Effect of blood contamination on the push-out bond strength of calcium silicate cements

Braz. dent. j; 29 (2), 2018
Abstract This study investigated the effect of blood-contamination on the push-out bond strength of BiodentineTM (BD) and MTA Angelus® (MTA-A) to root dentin over time. Twenty-five teeth were sectioned horizontally to obtain 120 root slices. The lumens were filled with MTA-A or BD: 60 for each cement (3...

Reação tecidual em subcutâneo de ratos frente a um cimento reparador à base de MTA com alta plasticidade

Este estudo teve como objetivo avaliar a biocompatibilidade, através de análise histopatológica e de imuno-histoquímica, de um novo cimento reparador à base de MTA com alta plasticidade: MTA HP (Angelus Londrina, PR). O MTA branco (Angelus Londrina, PR), e um material a base de óxido de zinco e eug...

Root perforations: a review of diagnosis, prognosis and materials

Braz. oral res. (Online); 32 (supl.1), 2018
Abstract: Root perforation results in the communication between root canal walls and periodontal space (external tooth surface). It is commonly caused by an operative procedural accident or pathological alteration (such as extensive dental caries, and external or internal inflammatory root resorption). D...
