Modified Goldner Trichrome for Non-decalcified Mineralized Tissue Plastinated and Embedded in Resin

Int. j. morphol; 42 (2), 2024
SUMMARY: Over time, Goldner's trichrome staining has been essential in paraffin soft tissue research. However, its classic application involves prior decalcification, generating disadvantages in the integrity of the samples and the interpretation of results. This study seeks to overcome the limitations a...

Root filling quality and bond strength of endodontic sealers to human and bovine dentin

RFO UPF; 28 (1), 2023
Objetivo: Este estudo teve como objetivo comparar a qualidade da obturação e a resistência de união de dois cimentos endodônticos, AH Plus e Bio-C Sealer, em dentes humanos e bovinos. Métodos: Os canais radiculares de 60 dentes unirradiculares [30 humanos (H) e 30 bovinos (B)] foram preparados e ob...

Mechanical behavior of different machinable ceramic crowns using vertical and horizontal preparations: an in-vitro study

Braz. dent. sci; 26 (1), 2023
Objective: the aim of this study was to compare the mechanical behavior of different ceramics when used in thin vertical preparations versus traditional horizontal preparation. Material and Methods: two stainless-steel dies were milled to simulate a minimally invasive vertical preparation (VP) and a t...

Influência dos cimentos obturadores biocerâmicos versus o AH Plus® na dor pós-operatória, penetração em túbulos dentinários e atividade antimicrobiana: revisões sistemáticas e meta-análises

O objetivo desse estudo de revisões sistemáticas e meta-análises foi responder se os cimentos biocerâmicos resultam melhores efeitos para a dor pós operatória, capacidade em penetração em túbulos dentinários e atividade antimicrobiana em comparação ao cimento AH Plus®. Foram conduzidas duas ...

Molhabilidade de um cimento endodôntico à base de resina epóxi na dentina tratada com diferentes protocolos de quelação

Dent. press endod; 11 (3), 2021
Objetivo: Avaliar a molhabilidade do cimento AH Plus em contato com a dentina radicular após diferentes protocolos quelantes envolvendo ácido etidrônico (HEBP) e o EDTA. Métodos: Cinquenta e seis fatias de dentina radicular foram utilizadas e irrigadas com 5.25% de hipoclorito de sódio (NaOCl) ou co...

A comparative evaluation of the sealing ability of two calcium silicate based sealers and a resin epoxy-based sealer through scanning electron microscopy and bond strength: an in vitro study

Braz. j. oral sci; 20 (), 2021
Aim: this study aimed to compare the sealing ability of two types of commercially available calcium silicate bioceramic based root canal sealers and a resin based root canal sealer. Methods: Twenty one single-rooted teeth were used, samples (n= 21) were randomly divided into three groups according to the...

Physicochemical properties, cytocompatibility and antibiofilm activity of a new calcium silicate sealer

Braz. dent. j; 32 (4), 2021
Abstract The aim of this study was to evaluate the physicochemical properties, cytocompatibility and antibiofilm activity of a new calcium silicate-based endodontic sealer, Sealer Plus BC (MK Life, Brazil), in comparison with TotalFill BC Sealer (FKG Dentaire SA, Switzerland) and AH Plus (Dentsply, Germa...

M1 and M2 macrophages phenotypes modulation after stimuli with materials used in endodontic treatment

Braz. dent. j; 32 (3), 2021
Abstract The aim of this study was to evaluate the M1 and M2 macrophage modulation after stimuli with different materials used during endodontic treatment. In bone marrow-derived macrophage cell culture, from males C57BL/6 wild-type (WT) mice, gene expression analysis of markers to M1 and M2 macrophages ...

Antimicrobial Activity of Bioceramic Root Canal Sealers: A Systematic Review

Actually, bioceramic endodontic sealers represent an advantageous option for root canals sealing due to their multiple properties. There are several in vitro studies about their antimicrobial properties, however, their comparative antimicrobial potential, compared with other types of endodontic sealers i...
