Context Root canal anatomy is evaluated using different methodologies. Aims The aim of this study is to evaluate and classify root canal morphology and dentin thicknesses (DT), comparing radiographic and micro-computed tomography (CT) analysis. Materials and Methods Canal diameter and DT of mandibular incisors (n = 520) were evaluated using digital radiographs in buccolingual (BL) and mesio...

PURPOSE This article is to describe a modified device for intraoral radiography which was developed to obtain reproducible radiographic images for assessment of distal osseous defects of the mandibular second molar (2 Mm) after impacted third molar (3 Mm) surgery. MATERIALS AND METHODS A commercial available alignment system for posterior region was modified by adding a reference gauge pin (m...

objective: after introduction of digital radiography into dentistry several methods of image acquisition were accessible in the field of dentistry. in many instances it is necessary to digitize analog images. there is no overall acceptable method for image digitization so all different types of images can be comparable. the objective of this study was to compare the diagnostic accuracy of diffe...

Six test dental radiographic films with varying resolutions and exposure times were evaluated diagnostically by 334 dentists. Each dentist completed a questionnaire relative to observations, dental education, practice profile, film utilization, and opinions on how electronic enhancement of the film affected his diagnostic ability. More than 60% identified 12-20 paired lines per mm of resolution...

The Tonnis radiographic classification of developmental dysplasia of the hip (DDH) has been widely used. The International Hip Dysplasia Institute (IHDI) classification, a new classification system recently developed by the IHDI, is beginning to be applied to evaluate DDH with the absence of an ossification center. This study aimed to validate its reliability in evaluating DDH with an ossificat...

OBJECTIVES Optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients' costs and radiation dose. This study sought to evaluate the effects of different viewing conditions on radiographic interpretation. MATERIALS AND METHODS This diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hole...

In this paper, we investigate the problem of classifying a subset of environmental sounds in movie audio tracks that indicate specific indexical semiotic use. These environmental sounds are used to signify and enhance events occurring in film scenes. We propose a classification system for detecting the presence of violence and car chase scenes in film by classifying ten various environmental so...

Computed Radiography (CR) can be a viable alternative for conventional film-based industrial radiography. This new technology uses flexible and re-usable storage phosphor plates that can be used in a fashion similar to film. To ensure that CR provides Probability of Detection (POD) performance for flaw indications that is equivalent to that of film radiography, international standards have been...
