The coronavirus-19 (COVID-19) pandemic caused by Coronavirus is causing severe acute respiratory infections. profession of dental health service workers must know the proper infection prevention and control. care in low-middle-income countries at odds with developed facing challenges a lack personal protective equipment (PPE) infrastructure constraints. This study aims to determine control stra...
A method of acquiring clear three-dimensional image of human tooth in vitro, which is based on optical coherence tomography, is described. The background noise of the cross-section image is eliminated by image preprocessing algorithms, then the threedimensional image is reconstructed by ray-casting algorithm and gives the whole view of dental crown which contains dentin and enamel. A plane can ...
A broad range of image processing applications require image databases during development and testing. Whilst some image databases have been assembled with specific applications in mind, others are intended for more general use, with image content that is purposefully not application-specific. General-purpose image databases are in frequent use in the development of new compression algorithms, ...
background: a comprehensive database, comprising geometry and properties of human teeth, is needed for dentistry education and dental research. the aim of this study was to create a three-dimensional model of human teeth to improve the dental e-learning and dental research. methods: in this study, a cross-section picture of the three-dimensional model of the teeth was used. ct-scan images wer...
Proteins are sources of many peptides with diverse biological activity. Some of them are considered as valuable components of foods and drug targets with desired and designed biological activity. We are now entering an era rich in biological data in which the field of bioinformatics is poised to exploit this information in increasingly powerful ways. There are currently many databases all over ...
dental status may influence food intake. the aim of this review was to summarize the earlier investigations on the association between food intake and dental status. we searched the electronic databases of pubmed and the cochrane library for articles published until 30 february, 2012. to reach the related published articles, medical subject heading (mesh) terms of ‘oral health,’ ‘masticatory pe...
OBJECTIVES The accuracy of two commercially available systems for image-guided dental implant insertion based on infrared tracking cameras was compared with manual implantation. MATERIAL AND METHODS Phantoms of partially edentulous mandibles were used. In a master phantom, pilot boreholes for dental implants were placed. These boreholes were reproduced in slave phantoms using either of the tw...
