Clinical implementation of comprehending dentin on a microscopic level

Int. j. morphol; 41 (1), 2023
SUMMARY: The aim of the present in vitro study is to visualize dentin to get an in-depth knowledge of the nature of dentin that could provide useful information regarding conditioning dentinal substrate when treating dentinal lesions. Forty-nine extracted human third molars were obtained and prepared to ...

Adhesión a dentina parte I: características del sustrato y sistemas adhesivos
Dentin bonding part I: substrate characteristics and bonding systems

La Odontología Restauradora contemporánea no puede concebirse sin la adhesión de los materiales restauradores a las estructuras dentarias. En mu-chos procedimientos restauradores, no sólo el esmal-te sino también la dentina se encuentra involucrada, por lo tanto, la adhesión a esta última juega un...

Caracterización microscópica de la dentina de dientes temporales
Microscopic characterization of the dentin of temporary teeth

Rev. ADM; 78 (6), 2021
La dentina se compone de un mineral de fosfato de calcio identificado como dahllita, que se dispone en pequeños cristales de hidroxiapatita carbonatada con dimensiones de 36 × 25 × 4 nm, y por una fase orgánica cuyo principal componente es el colágeno tipo 1 en 90%, que se orienta en forma de malla....

Evaluation of the sealing ability of different root canal sealers: a combined SEM and micro-CT study

J. appl. oral sci; 26 (), 2018
Abstract Objective: The purpose of this study was to analyze the ability of multiple compounds to seal the dental tubules using scanning electron microscopy (SEM) and micro-computed tomogra-phy (micro-CT). Material and Methods: Twenty-four single-root human mandibular premolars were selected and instru...

Effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin

Abstract This study aimed to evaluate the effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin. Sixty root canals from mandibular incisors were instrumented and randomly divided into six groups (n = 10) according to the irrigant used: QMiX, 17% EDTA, 10% citric...

Effectiveness of different final irrigation techniques and placement of endodontic sealer into dentinal tubules

Abstract: The aim of this study was to compare two irrigation techniques and four devices for endodontic sealer placement into the dentinal tubules. Ninety-nine single-rooted human teeth were instrumented and allocated to either the control (CO) (n=11) or experimental groups according to the irrigation m...

Effect of EDTA on TGF-β1 released from the dentin matrix and its influence on dental pulp stem cell migration

Braz. oral res. (Online); 30 (1), 2016
Abstract: Bioactive molecules stored in dentin, such as transforming growth factor beta1 (TGF-b1), may be involved in the signaling events related to dental tissue repair. The authors conducted an in vitro evaluation of the amount of TGF-b1 released from dentin slices after treatment with 10% ethylenedia...

Effect of endodontic sealer and resin luting strategies on pull-out bond strength of glass fiber posts to dentin

Acta odontol. latinoam; 23 (3), 2010
The aim of this study was to evaluate the influence of eugenolcontaining endodontic sealers and luting strategy on the pull-out bond strength of glass fiber posts to dentin. Sixty-four bovine incisors were randomly assigned into two groups of 32 specimens each for obturation procedure with gutta-percha o...

Resistência ao cisalhamento da união de sistemas adesivos sobre dentina
Shear bond strength evaluation of the adhesive bond systems on dentin: an in vitro study

Avaliou-se a resistência de união ao cisalhamento de 11 sistemas adesivos sobre dentina e a união na interface compósito-dente. Condicionou-se a superfície da dentina de 88 dentes e aplicou-se o sistema adesivo selecionado. Depois, foi aplicado e polimerizado o comósito restaurador, submetendo-se o...

Comportamento biológico da dentina cariada humana após o capeamento pulpar indireto: estudo morfológico pela microscopia de luz e eletrônica

No presente trabalho, foram utilizados molares permanentes de humanos com cáries profundas, tratados pelo método do capeamento pulpar indireto. Os pacientes relacionados eram de ambos os sexos, com faixa etária entre 6 a 10 anos. A técnica foi realizada em duas sessöes, com intervalo aproximado de 4...
