BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

PURPOSE The aim of this study was to compare the performance of direct digital radiography and traditional dental radiography for the detection of proximal surface dental caries in the mixed dentition. METHODS 15 quadrants of extracted teeth, arranged from the primary canine to permanent first molar, were imaged using direct digital (Schick Technologies, Long Island City, NY, USA) and convent...

background and aims. the aim of the present study was to compare the effect of application of an image processing mode of a colorizer on the efficacy of the detection of interproximal carious lesions viewed in direct digital radiography. materials and methods. a total of 102 proximal surfaces of extracted human premolars on direct digital images were evaluated by three observers with and withou...

abstract background and aim: cone beam computed tomography (cbct) produces high-quality data in periodontal diagnosis and treatment planning. the aim of this study was to compare the accuracy of cbct with intraoral digital and conventional radiography in the measurement of periodontal bone defects.  methods and materials: in this diagnostic research, two hundred and eighteen artificial osseous ...

abstract background and aim: considering the importance of detection of secondary caries, the adverse consequences of false positive and false negative diagnoses and the gap of information in the diagnostic efficacy of digital sensors in detection of secondary caries, this in vitro study sought to compare the diagnostic efficacy of two different resolutions of radiographs obtained by photostimu...

Nanoparticles containing mixed lipid monolayer shell, biodegradable polymer core and rabies virus glycoprotein (RVG) peptide as brain targeting ligand, were developed for brain targeted delivery of paclitaxel (PTX) to treat malignant glioma. RVG conjugated PTX loaded NPs (RVG-PTX-NPs) had the desirable size (~140 nm), narrow size distribution and spherical shape. RVG-PTX-NPs showed poor uptake ...

AIM Compare the measurement of working length with three different methods manual tactile sensation, digital radiography and Mutidetector computed tomography(MDCT). MATERIALS AND METHOD 40 human premolar extracted for orthodontic purpose were selected. Teeth were store in sodium chloride (0.9%) during the study. Access cavity was prepared and canal patency was seen with no 10 file in each too...
