Caries may be halted or reversed in their progression by early detection, better hygiene habits, and coadministered drugs. The major clinical procedures for identifying dental caries are visual-tactile examination radiography. However, due to location, approximate exceedingly difficult detect affect the assessment. Incorrect interpretations also hinder diagnostic procedure. Computational approa...
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 ...
Dental caries is the leading cause of tooth loss, which can promptly be prevented if detected in early stages of progression. Unfortunately, conventional diagnostic modalities currently used in dentistry lack the sensitivity to detect early caries. The authors' intention is to compare the ability of polarized Raman spectroscopy and thermophotonic imaging to make early caries diagnosis. Extracte...
Background and Aim: In recent decades many guidelines has been conducted by radiation protection organizations about radiation protection in dentistry. This study was designed to evaluate the observance of these guidelines in educational clinics of all dental schools in Iran.Materials and Methods: In this cross-sectional study a questionnaire based on National Radiation Protection guidelines wa...
PURPOSE This study aimed to investigate the effect of changing the kilovoltage peak (kVp) on the radiographic assessment of dental caries. MATERIALS AND METHODS Seventy-five extracted posterior teeth with proximal caries or apparently sound proximal surfaces were radiographed with conventional E-speed films and a photostimulable phosphor system using 60 kVp and 70 kVp for the caries assessmen...
statement of the problem: dental caries in infants and young children is prevalent worldwide; its magnitude and associated factors vary between communities because of cultural and social economic differences. no such information was available for pre-school children in mbeya city. purpose: to determine dental caries status and associated factors in 2 to 4-year-old children in mbeya city. materi...
Digital dental radiographic imaging is considered to be as diagnostically accurate as conventional film-based radiography. In addition, many digital radiographic systems offer various image enhancements that may aid in image interpretation. However, neither type of radiographic imaging technique perfectly correlates radiographic diagnoses with clinical findings. Moreover, visual digital enhance...
UNLABELLED Idiopathic cervical resorption is a rare form of external resorption, usually with no external signs, and can be misdiagnosed as dental caries or other types of tooth resorption. Here we report a case in which, during routine radiography, an asymptomatic lower right molar presented with a radiolucency at the cervical region, with no obvious aetiologic factor identified. CLINICAL RE...
Resumo: Este estudo utiliza um modelo de inteligência artificial, uma rede neural com base radial (RBF), para dar suporte a diagnósticos radiográficos de cáries dentárias. Cento e sessenta imagens radiografias de faces proximais de dentes humanos extraídos foram avaliadas no que se refere à presença ou ausência de cárie por vinte e cinco examinadores. As condições reais de cada dente, denominad...
Wilhelm Roentgen first discovered X-rays in 1895. Since its introduction the mid-1980s, digital radiography has surpassed traditional screen-film radiography. 2000, more than 75 percent of medical clinics United States have migrated to (DR). In fact, US government ordered that all records be converted digital. Indirect, direct, or semi-direct pictures are types currently available. Forensic rad...
