Debris extrusion and foraminal deformation produced by reciprocating instruments made of thermally treated NiTi wires

J. appl. oral sci; 26 (), 2018
Abstract Objective To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at t...

TiF4 varnish protects the retention of brackets to enamel after in vitro mild erosive challenge

J. appl. oral sci; 26 (), 2018
Abstract The effect of fluoride agents on the retention of orthodontic brackets to enamel under erosive challenge is little investigated. Objective: The aim of this study was to evaluate the effect of titanium tetrafluoride (TiF4) and sodium fluoride (NaF) agents on the shear bond strength of brackets t...

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...

Evaluation of the effect of dose-dependent platelet-rich fibrin membrane on treatment of gingival recession: a randomized, controlled clinical trial

J. appl. oral sci; 26 (), 2018
Abstract Miller's class I gingival recessions (GR) have been treated using coronally advanced flap (CAF) with platelet-rich fibrin membrane (PRF membrane) or connective tissue graft (CTG). Objective: The aim of this study was to evaluate the effect of different multiple layers of PRF membranes for the t...

To what extent does hyaluronic acid affect healing of xenografts? A histomorphometric study in a rabbit model

J. appl. oral sci; 26 (), 2018
ABSTRACT Among the many graft materials that have been used for the treatment of bone defects in oral and maxillofacial regions is xenograft. To improve osteoconductive effects of xenografts, they have been combined with various biocompatible materials, such as hyaluronic acid and bone morphogenetic prot...

The effects of IL-10 gene polymorphism on serum, and gingival crevicular fluid levels of IL-6 and IL-10 in chronic periodontitis

J. appl. oral sci; 26 (), 2018
Abstract Objective Anti-inflammatory cytokines play a crucial role in periodontitis by inhibiting synthesis of pro-inflammatory cytokines. The purpose of this study was to evaluate the effect of interleukin-10 (-597) gene polymorphism and genotype distributions on chronic periodontitis (CP) development ...

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...

Alveolar bone repair with strontium- containing nanostructured carbonated hydroxyapatite

J. appl. oral sci; 26 (), 2018
ABSTRACT Objective: This study aimed to evaluate bone repair in rat dental sockets after implanting nanostructured carbonated hydroxyapatite/sodium alginate (CHA) and nanostructured carbonated hydroxyapatite/sodium alginate containing 5% strontium microspheres (SrCHA) as bone substitute materials. Meth...
