The aim of this study was to compare the effect of different mechanical surface treatments and chemical bonding protocols on the tensile bond strength (TBS) of aged composite. Bar specimens were produced using a nanohybrid resin composite and aged in distilled water for 30 days. Different surface treatments (diamond bur, phosphoric acid, silane, and sandblasting with Al₂O₃ or CoJet Sand), as we...

IntroductionThe aim of this study is to report the management of large periapical lesion using triple antibiotic paste as an alternative intra-canal medicament in nonsurgical endodontic treatment. Case reportan 11 year old male patient with large periapical lesion in mandibular anterior region, treated using conservative non-surgical endodontic treatment. Calcium hydroxide-iodoform paste (Vitap...

Introduction : Nanohybrid composite resin is a restorative material that often used because of its aesthetics and adequate mechanical properties. One the properties nanohybrid resins diametral tensile strength, which affects strength when receiving chewing loads in oral cavity. The value can be influenced by several factors, namely food, drink, saliva. Human saliva has different pH levels alway...

Introduction: Composite materials may be exposed to chemicals in food and beverages the oral cavity, which can lead changes surface roughness. The aim of this vitro study was evaluate roughness two restorative after exposure coffee green tea followed by a dental bleaching procedure. Methods: For nanofilled composite microhybrid composite, 15 samples each were fabricated. Five specimens from sto...

This study tested two hypotheses. The first null hypothesis affirms that there is no statistical difference when composite resin is submitted to knoop or vickers microhardness using different testing protocols. The second hypothesis tested the possible influence of elastic modulus of composite resin in microhardness tests. Two nanohybrid composites were used with different viscosity behavior (G...

Here we fabricate a new type of flexible and versatile nanohybrid paper electrode by ultrasonic-electrodeposition of PtPd alloy nanoparticles on freestanding ionic liquid (IL)-functionalized graphene paper, and explore its multifunctional applications in electrochemical catalysis and sensing systems. The graphene-based paper materials demonstrate intrinsic flexibility, exceptional mechanical st...

Methotrexate (MTX), an anticancer agent, was successfully intercalated into the anionic clay, layered double hydroxides to form a new nanohybrid drug. The coprecipitation and subsequent hydrothermal method were used to prepare chemically, structurally, and morphologically well-defined two-dimensional drug-clay nanohybrid. The resulting two-dimensional drug-clay nanohybrid showed excellent collo...
