Non-contact profilometry of eroded and abraded enamel irradiated with an Er: YAG laser

J. appl. oral sci; 26 (), 2018
Abstract Literature has reported positive results regarding the use of lasers in the control of erosive lesions; however, evaluating whether they are effective in the control of the progression of erosive/abrasive lesions is important. Objectives This study aimed to evaluate the effect of the Er:YAG las...

Porosity, water sorption and solubility of denture base acrylic resins polymerized conventionally or in microwave

J. appl. oral sci; 26 (), 2018
Abstract The proper selection of polymerization cycle is important to prevent overheating of the monomer that could cause degradation, porosity and, consequently, deleterious effects on the denture base properties. Objective This study evaluated the porosity, water sorption and solubility of acrylic res...

Model resin composites incorporating ZnO-NP: activity against S. mutans and physicochemical properties characterization

J. appl. oral sci; 26 (), 2018
Abstract Although resin composites are widely used in the clinical practice, the development of recurrent caries at composite-tooth interface still remains as one of the principal shortcomings to be overcome in this field. Objectives To evaluate the activity against S. mutans biofilm of model resin comp...

Doxycycline-containing glass ionomer cement for arresting residual caries: an in vitro study and a pilot trial

J. appl. oral sci; 26 (), 2018
Abstract In a previous study, we demonstrated that the incorporation of doxycycline hyclate (DOX) into resin-modified glass ionomer cement (RMGIC) inhibited important cariogenic microorganisms, without modifying its biological and mechanical characteristics. In this study, we keep focused on the effect o...

Solubility, porosity and fluid uptake of calcium silicate-based cements

J. appl. oral sci; 26 (), 2018
Abstract Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated after immersion in distilled water for 7 and 30 days. Porosity was evalu...

Can whitening toothpastes maintain the optical stability of enamel over time?

J. appl. oral sci; 26 (), 2018
Abstract Besides the effects on the health of individuals, cigarette smoking can also interfere with the appearance of their teeth. Objective: To evaluate the effect of cigarette smoking-toothbrushing-cycling (CSTC) with whitening toothpastes on the roughness and optical behavior of bovine enamel for ei...

Determination of the effective anticandidal concentration of denture cleanser tablets on some denture base resins

J. appl. oral sci; 26 (), 2018
Abstract Objective Although the effectiveness of chemical cleansing against Candida albicans biofilm has been shown, the effective concentration of denture cleanser tablets has not been studied. The aim of this study was to assess the effect of three denture materials against Candida albicans biofilm an...

Effect of filler size and filler loading on wear of experimental flowable resin composites

J. appl. oral sci; 26 (), 2018
Abstract The relationship between wear resistance and filler size or filler loading was clarified for the universal resin composite; however, their relationship in flowable resin composites has not been clarified. Objectives: The purpose of this study was to investigate the effect of filler size and fil...

Comparison of deflection forces of esthetic archwires combined with ceramic brackets

J. appl. oral sci; 26 (), 2018
Abstract Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coa...

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...
