We develop a Computer Aided Diagnosis (CAD) system, which enhances the performance of dentists in detecting wide range of dental caries. The CAD System achieves this by acting as a second opinion for the dentists with way higher sensitivity on the task of detecting cavities than the dentists themselves. We develop annotated dataset of more than 3000 bitewing radiographs and utilize it for devel...

PURPOSE The purpose of this study was to evaluate a modified bitewing film holder based on preschoolers' acceptance and the diagnostic quality of radiographic images. METHODS Sixty-six 3- to 5-year-old children were radiographed with the modified device. Acceptance was assessed according to their behavior during the radiographic examination and to their perception of the procedure. In only th...

Clinicians strive to reduce the exposure of patients to X-ray radiation in an effort to decrease its harmful effects on the body. A potential strategy for achieving this goal is the use of high-speed films that require less exposure to radiation to generate a diagnostic image. There are two film types commonly used in intraoral radiography: high speed or "Ekta-speed" film (Type E) and normal sp...

BACKGROUND In order to determine the presence or absence of a certain disease, multiple diagnostic tests may be necessary. Performance of these tests can be sequentially evaluated. AIMS The aim of the study is to determine the contribution of the test in each step, in reducing diagnostic uncertainty when multiple tests are sequentially used for the diagnosis. STUDY DESIGN Diagnostic accurac...

PURPOSE This prospective, cross-sectional study examined the sensitivity and specificity of clinical assessment compared to bitewing radiographs in the detection of occlusal dentin caries in permanent molars. METHODS Subjects were 481 children aged 5-12 years from a school-based dental clinic. Occlusal surfaces of 1929, sealed and unsealed first and second permanent molars were examined clini...

In digital radiography the image can be enhanced and thereby an incorrect exposed radiograph can appear to have optimal brightness but with limited information and possibility to diagnose e.g. caries. The primary aim of this study was to determine if different exposure times have an impact on the accuracy in diagnosis of approximal caries lesions in bitewing radiographs using a CMOS system. If ...

This randomized clinical trial aimed to assess the efficacy of sealing occlusal carious lesions in permanent teeth. The sample consisted of 54 occlusal carious lesions in permanent molars and premolars of 49 patients aged 8-43 years (median: 19 years). The inclusion criteria comprised the presence of a cavity with no access allowing biofilm control. The maximum depth of the lesion was the middl...

Introduction: Hidden caries is a term used to describe occlusal dentine caries that is missed on a visual examination, but is large and demineralised enough to be detected by another exam for example, radiographs. Case report: This article reports a case of large dentine caries, which presented as to be a small pit-and-fissure carious lesion on the occlusal surface of the right mandibular perma...

Introduction: Bite wing radiographs are indicated in children with closed posterior contacts. Given the fact that nowadays bitewing radiographs are taken using both paper loop and film holder, the aim of this study is the evaluation of acceptance and diagnostic quality of two methods. Materials and Methods: This study is a sort of diagnostic accuracy test that was performed on 20 6-8 year old ...
