one of the challenging issues in managing the existing large digital image libraries and databases is content based image retrieval (cbir). the accuracy of image retrieval methods in cbir is subject to effective extraction of image features such as color, texture, and shape. in this paper, we propose a new image retrieval method using contourlet transform coefficients to index texture of the im...

context this study aimed to provide an overview of the literature on the radiopacity of dental materials in order to emphasize its importance. evidence acquisition english-language literature was investigated using manual and electronic searches for the terms “radiopacity,” “dental material,” “cement,” “composite,” “ceramic,” “endodontic root canal sealer,” “bone graft,” and “acrylic resin” in ...

Introduction: Dental fear and anxiety (DFA) are still prevalent in adults should be considered a dental public health problem. Objective: To analyze the literature on anxiety, focusing cause, diagnosis, treatment, prevalence. Methodology: PubMed, SCOPUS Google Scholar databases were reviewed to find recent articles published management provisionalization of implants with following keywords

As digital dental images become widely available, a new Electronic MR system (EMR) will be critical for the success of applying new technology to dental care. This project is designed an image-based and spatially-oriented EMR for dental surgery. A new panoramic image-based annotation model will be developed, which will complement dental charting precisely locating specific spatial findings for ...

background: dental traumas are common among children and adolescents in many societies posing health and social problems. the aim of this study was to conduct a systematic review and meta-analysis on prevalence, etiology, types, and other epidemiologic aspects of dental trauma in children and adolescents (0-18 years old). methods: in this systematic meta-analytical review, data were collected s...

A hand-held, battery-powered dental intraoral x-ray system (60 kV, constant potential output) was compared to a conventional, wall-mounted intraoral x-ray system (70 kVp, self-rectified output) in terms of image quality, and patient and staff radiation doses. The image quality comparison included quantitative measurements of image sharpness (resolution) and contrast. Patient doses were compared...

Dental Xray image segmentation (DXIS) is an vitally necessary process in Practical dentistry for diagnosis of periodontitis diseases from an Xray image. DXIS have been investigated to get high accuracy of segmentation. In this paper, we propose a new cooperative scheme that applies semisupervised Fuzzy clustering algorithm to DXIS. Specifically, the Otsu method is used to remove the Background ...
