Clinical wear of approximal glass ionomer restorations protected with a nanofilled self-adhesive light-cured protective coating

J. appl. oral sci; 26 (), 2018
Abstract High viscous glass ionomer cement (GIC) has gained popularity as a restorative material; however, high wear is pointed as one of the major drawbacks of this material. Protective surface coatings were developed to protect GIC from water contamination with the additional advantage of occluding any...

Introdução: Diversos materiais restauradores são indicados para a restauração de dentes decíduos posteriores, como amálgama, resina composta, cimento de ionômero de vidro convencional, cimento de ionômero de vidro modificado por resina e resinas compostas modificadas com poliácidos (compômeros...

Avaliação de rugosidade, dureza e superfície dos cimentos de ionômero de vidro após diferentes sistemas de acabamento e polimento

Introdução: A rugosidade de superfície é uma limitação que interfere nos desempenhos mecânico e estético do cimento de ionômero de vidro (CIV), sendo necessária a utilização de procedimentos para acabamento e polimento adequados às propriedades desse material. Objetivo: Avaliar o efeito d...

In vitro and in vivo evaluations of glass-ionomer cement containing chlorhexidine for Atraumatic Restorative Treatment

J. appl. oral sci; 25 (5), 2017
Abstract Objectives: Addition of chlorhexidine has enhanced the antimicrobial effect of glass ionomer cement (GIC) indicated to Atraumatic Restorative Treatment (ART); however, the impact of this mixture on the properties of these materials and on the longevity of restorations must be investigated. The ...

Bond strength of a composite resin to glass ionomer cements using different adhesive systems

Introduction: Glass ionomer cements are often used as a base or cavity lining prior to restorative material. Objective: To evaluate the bond strength of a composite resin to different glass ionomer cements, when using a two-step conventional and self-etching adhesive systems. Material and method: Three...

Influence of caries risk on the retention of a resin-modified glass ionomer used as occlusal sealant: a clinical trial

Introduction: Little is known whether caries risk influence occlusal sealants retention. Objective: To determine the retention rates (RR) of the resin-modified glass ionomer cement used as occlusal sealant in permanent first molars of 6-8-year old schoolchildren and to analyze the influence of caries ri...

Avaliação da rugosidade superficial e análise morfológica de cimentos de ionômero de vidro: influência do armazenamento em saliva artificial

Introdução: O desenvolvimento dos cimentos de ionômero de vidro (CIVs) proporcionou vantagens aos procedimentos restauradores diretos devido a suas propriedades, como adesão química à estrutura dentária e liberação de flúor. No entanto, o ambiente bucal pode promover condições capazes de alte...

Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis

J. appl. oral sci; 25 (2), 2017
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatmen...

Influence of resin-modified glass ionomer and topical fluoride on levels of Streptococcus mutans in saliva and biofilm adjacent to metallic brackets

J. appl. oral sci; 25 (2), 2017
Abstract Decalcification of enamel during fixed orthodontic appliance treatment remains a problem. White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. The use of fluoride-containing orthodontic materials has shown inconclusive results on their ability to reduce dec...

Enhanced bioactive properties of BiodentineTM modified with bioactive glass nanoparticles

J. appl. oral sci; 25 (2), 2017
Abstract Objective To prepare nanocomposite cements based on the incorporation of bioactive glass nanoparticles (nBGs) into BiodentineTM (BD, Septodent, Saint-Maur-des-Fosses Cedex, France) and to assess their bioactive properties. Material and Methods nBGs were synthesised by the sol-gel method. BD ...
