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 ...

Efficacy evaluation of pepsin enzyme-based gel in chemo-mechanical caries removal on primary anterior teeth: a randomized controlled clinical study

Braz. dent. sci; 25 (4), 2022
Objective: To evaluate the efficacy of a new pepsin enzyme-based gel compared with Carisolv as a CMCR agent. Clinical and radiographical evaluations of recurrent caries were made 3 and 6 months after treatment. Material and Methods: A split-mouth designed randomized controlled clinical study was carrie...

Comparison of in vitro erosion protocols in bovine teeth to simulate natural erosion lesion: analysis of mechanical properties and surface gloss

J. appl. oral sci; 27 (), 2019
Abstract Objective The aim of this study was to compare two in vitro erosion protocols, in which one simulates in vivo conditions experienced by patients with gastroesophageal disorders or bulimia (HCl-pepsin protocol), and the other simulates the diet of an individual who consumes a high volume of eros...

Imobilização de pepsina em membranas liofilizadas de quitosana e O-carboximetilquitosana

Enzimas são proteínas utilizadas em processos tecnológicos diversos. Estas enzimas dependendo do tipo e grau de pureza são geralmente caras. Comumente as enzimas exigem controle contínuo do processo no que se refere à temperatura, pH, agitação, entre outros, e após o uso são descartadas, o que ...

Laboratory diagnosis of rabies by the fluorescent antibody test applied to brain tissues of experimentally inoculated mice and either preserved in formalin or under refrigeration

Avaliou-se a adequaçäo do emprego de cérebros preservados em formol para o estabelecimento rápido do diagnóstico da raiva pela reaçäo de imunofluorescência direta, utilizando a técnica de digestäo enzimática de pepsina e tripsina e método de impressäo para o preparo de lâminas. O delineamen...

Extracción de la pepsina aviar (EC 3.423.1) y su utilización como substituto de la quimosina en la elaboración de queso blanco pasteurizado

Se extrajo pepsina aviar a partir de estómagos glandulares de aves, para ser utilizada como substituto de la quimosina en a elaboración de queso blanco pasteurizado. La enzima extraida demostró poseer un rendimiento de 4,3 g de pepsina aviar liofilizada por cada kilogramo de estómagos glandulares, y ...
