AIMS AND OBJECTIVES To measure and compare the shear bond strength and adhesive remnant index of light-cure composite. (Enlight, Ormco.) and dual-cure composite (Phase II dual cure, Reliance Ortho). MATERIALS AND METHODS Sixty extracted human premolar teeth were divided into two groups: group I (blue): conventional light cure composite resin. (Enlight, Ormco.) and group II (green): dual cure ...

The samples were prepared according to the routine work for sample preparation in dental laboratories. After reaching dough stage, the mixture packed into dumbbell shaped of stainless steel mould and pressed in a hydraulic bench press for 25 min at room temperature. For heat-cure, the polymerization cycle was carried out using water bath, while self-cure done at room temperature. The residual m...

Background and aims: New dentin bonding agents and techniques have been developed to reduce microleakage and create higher bond strength. This in-vitro study compared the microleakage of three resin-based adhesives versus a GIC-based adhesive on class V composite restorations.  Materials and Methods: Class V cavities were prepared on the buccal surfaces of 72 sound premolars, randomly assigned ...

the method has been developed and validated for the determination of hydroquinone in liposomal formulation. the samples were dissolved in methanol and evaluated in 293 nm. the validation parameters such as linearity, accuracy, precision, specificity, limit of detection (lod) and limit of quantitation (loq) were determined. the calibration curve was linear in 1-50 µg /ml range of hydroquinone an...

in this paper the photocatalytic degradation of the anionic surfactant, linear alkylbenzene sulfonicacid (labsa) was investigated using uv radiation in the presence of tio2. our findingsdemonstrate that various parameters exert their individual influence on the photocatalytic degradationof surfactant in wastewaters. the mentioned parameters have been categorized as follow: the initialph of the ...

Malignant tumor which that arises from uncontrolled proliferation of melanocytes is melanoma. Its rare in India, compared to other tropical countries. Fair skin populations have higher incidences The relative mortality reduced nearly half with scrupulous use sunscreens - SPF 50 blocks 98% UVB rays. Melanomas are observed more countries like Australia and New Zealand (due actinic rays (UV B rays...

In recent years, the use of biomass for cost-effective synthesis nanoparticles has emerged as a promising green technology. Because their remarkable properties, such tunable surface plasmon resonance characteristics and high areas, bio-synthesised nanomaterials are receiving more scientific academic attention in various application sectors, especially catalysts environmental remediation. Green ...

In this paper, we present the development of a family novel, UV-curable, highly flexible, 3D printable silicone-based materials, mechanical properties which can be tuned simply by varying ratio polymerisable reagents within formulation. This tuneability is achieved exploiting balance between in-cure phase separation and differential reactivity formulation to successfully produce composite struc...
