Objective. The purpose of this study was to evaluate the efficiency of operating microscope compared with unaided visual examination, conventional and digital intraoral radiography for proximal caries detection. Materialsand Methods. The study was based on 48 extracted human posterior permanent teeth. The teeth were examined with unaided visual examination, operating microscope, conventional bi...

The aim of this study was to evaluate the ability of undergraduate dental students to match simulated ante- and post-mortem radiographs in human skulls with experts as controls for the 1)number of post-mortem images needed for a match, 2)accuracy of the matches, and 3)time spent for a match. A film bitewing was recorded in each side of 51 dentate dry human skulls (a.m.-images) and digital image...

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 ...

OBJECTIVE The aim of this study was to determine the prevalence of pulp stones (PS) in a Turkish dental patient population with respect to sexes and dental localization in relation between sex and this anomaly. MATERIALS METHODS A retrospective study was performed using bitewing radiographs of 814 patients ranging in age from 15 to 65. All data (age, sex, and location) was obtained from the f...

The aim of this research was to study the evolution of dental health of dental students during their academic training and to assess the extent to which the knowledge acquired was reflected in their own dental care. A sample of 107 students at the schools of dentistry and medicine (the latter as a comparison group) of the University of Barcelona, Spain, underwent an oral examination and complet...

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...

Conventional methods of caries detection, including the gold standard of histological examination, have certain disadvantages that must be addressed prior to validating any other diagnostic technique-current or new. Here we evaluated the validity of micro-computed tomography (micro-CT) as an alternative gold-standard technique for caries detection. Sixty teeth with suspected occlusal caries wer...

INTRODUCTION Knowledge of the anatomic location and dimension of the molar pulp chamber may preserve healthy pulp during operative procedure and reduce risk of perforation of chamber during access preparation. A review of literatures regarding the morphology of pulp chamber however revealed very little information; so the aim of this in vivo study was to measure the dimensions of first molar pu...

OBJECTIVE Direct in vivo MRI of dental hard tissues by applying ultrashort echo time (UTE) MRI techniques has recently been reported. The objective of the presented study is to clinically evaluate the applicability of UTE MRI for the identification of caries lesions. METHODS 40 randomly selected patients (mean age 41 ± 15 years) were enrolled in this study. 39 patients underwent a conventiona...
