Comparison between static and semi-dynamic models for microcosm biofilm formation on dentin

J. appl. oral sci; 27 (), 2019
Abstract Microcosm biofilm has been applied to induce carious lesions in dentin. However, no study has been done to compare the impact of the type of model for providing nutrients to microcosm biofilm formation on dentin. Objective This study compared the performance of two kinds of models (static and s...

Resin-modified glass ionomer containing calcium glycerophosphate: physico-mechanical properties and enamel demineralization

J. appl. oral sci; 27 (), 2019
Abstract Sources of calcium and phosphate have been added to dental restorative materials to improve their anticaries effect. Objective This study evaluated the effect of adding calcium glycerophosphate (CaGP) to resin-modified glass ionomer cement (RMGIC) on the physico-mechanical properties, ion rele...

Effect of hydroalcoholic extract of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves on the viability and activity of microcosm biofilm and on enamel demineralization

J. appl. oral sci; 27 (), 2019
Abstract Objectives: The aim of this study was to assess the effect of Myracrodruon urundeuva All. and Qualea grandiflora Mart. leaves hydroalcoholic extracts on viability and metabolism of a microcosm biofilm and on enamel demineralization prevention. Methodology: Microcosm biofilm was produced on bov...

Effect of fluoride application during radiotherapy on enamel demineralization

J. appl. oral sci; 27 (), 2019
Abstract Radiation-related caries are one the most undesired reactions manifested during or after head and neck radiotherapy. Fluoride application is an important strategy to reduce demineralization and enhance remineralizaton. Objective: To evaluate the effect of the topical application of fluoride dur...

Os medicamentos infantis podem causar erosão na superfície de dentes decíduos? Revisão sistemática da literatura

HU Rev. (Online); 45 (1), 2019
Introdução: A erosão dentária é caracterizada por uma perda progressiva e irreversível dos tecidos dentários mineralizados que ocorre sem envolvimento bacteriano. Acredita-se que o uso frequente de medicamentos líquidos orais, em crianças, possa desenvolver erosão dentária visto que esses medi...

Erosive potential of sports beverages on human enamel "in vitro"

Rev. bras. med. esporte; 24 (5), 2018
INTRODUCTION: The low pH of sports drinks may cause tooth enamel demineralization. Objective: To measure Vickers hardness of human enamel exposed to sports drinks. METHODS: Human molars were used to collect the enamel samples. Each sample had a test surface (exposed to the drinks) and a control surface (...

Desenvolvimento de lesões de cárie em dentina em um modelo de biofilme simplificado in vitro: um estudo piloto

Introdução: Modelos laboratoriais de biofilmes vêm sendo desenvolvidos com a finalidade de simular o ambiente bucal e o processo de formação da cárie dental. Objetivo: Estabelecer e padronizar um modelo de biofilme in vitro para o desenvolvimento de lesões de cárie em dentina. Material e métod...

In vitro effect of energy drinks on human enamel surface

Introduction: Energy drinks (ED) possess low pH and citric acid in their composition, making them potentially erosive beverages that can contribute to the high dental erosion rates found currently in the general population and also in young people. Objective: To evaluate the mean pH and titratable acidi...

Effect of Myracrodruon urundeuva and Qualea grandiflora extracts on viability and activity of microcosm biofilm and prevention of enamel demineralization in vitro

The objective of this study was to evaluate the antimicrobial and anti-caries effects of two plant extracts. The first chapter dealt with a review of the literature whose objective was to discuss the antimicrobial potential of Brazilian natural agents on the biofilm related to dental caries and gingiviti...
