Background: Previous studies have shown that exposure to electromagnetic fields produced by magnetic resonance imaging or mobile phones can lead to increased microleakage of dental amalgam.Objective: The aim of the present study was to investigate the effect of electromagnetic field of a commercial dental light cure device and a common GSM mobile phone on microleakage of amalgam restorations.Ma...

aim: the purpose of this study was to compare the difference in the output intensity of light emitting diode (led) light cure (lc) devices with and without a protective sleeve and its clinical significance.  materials and methods: the output intensity of 152 lc units in dental offices across the state of odisha were examined. the collection of related information included an average number of e...

OBJECTIVE To identify the main types of HIV cure-related strategies and examine possible risks (and benefits) associated with participating in HIV cure-related research studies. METHODS We undertook a scoping review to first map out the landscape of HIV cure-related research and then examined the risks and potential benefits associated with participating in HIV cure research. Given the early ...

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 ...

Tuberculosis remains a public health problem in Brazil. In 2003, controlling tuberculosis was highlighted as a priority among health public policies. The article reports the Brazilian response to this challenge, describing the main strategies of the National Control Plan for 2003 to 2006. Among its main results are: expansion of strategic coverage of the supervised treatment, increase in the pe...
