BACKGROUND To investigate differences in the estimated minimum remaining dentin thickness (RDT) between periapical radiographs using the paralleling and parallax technique, after simulated removal of broken instrument from the mesiobuccal (MB) canal of maxillary first molar in virtual simulation model. The 3D measurement was taken as the standard for comparison. METHODS Thirty-six maxillary f...

introduction: bacterial infection of tooth pulp can progress into periapical diseases. root canal treatment has been established as the best treatment. in cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. materials & methods: in this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. all teeth showed...

background : retakes of intra oral radiographs happen frequently in dental practice although radiographic courses train dental students in consecutive semesters. to reduce the patient exposure as much as possible it is mandatory to reduce the number of retakes both in radiology clinics and educational centers. materials and methods : 3188 periapical radiographs taken by bisect-angle technique w...

a case of a compound odontoma which caused delayed eruption of right maxillary central incisor in a ten year old girl is presented with clinical and radiographic findings. the patient presented with complaint of a hard painless swelling in the right anterior region of the maxilla and absence of right maxillary central incisor. after clinical examination, periapical and occlusal radiographs of t...

abstract: apexification with calcium hydroxide is associated with certain difficulties, such as longer treatment time, risk of tooth fracture and incomplete calcification of apical bridge. mineral trioxide aggregate (mta) is an alternative material that can be used for apexification of open apices due to its biocompatibility, non-mutagenicity, non-neurotoxicity, regenerative abilities, and good...

AIMS To evaluate the impact of the quality of coronal restorations scored on a clinical and radiographic basis and the quality of root fillings on periapical health. METHODOLOGY Periapical radiographs were taken of 745 root-filled teeth, randomly selected from patients attending the Ghent University Dental School. The teeth had not received restorative treatment in the previous year. The coro...

BACKGROUND Cone beam computed tomography (CBCT) has been largely used in dentistry. Nevertheless, there is lack of evidence regarding CBCT accuracy in the diagnosis of early periodontal lesions as well as the correlation between accuracy and lesion size. The aim of this study was to evaluate accuracy of CBCT and conventional intraoral radiographs in detecting different-sized interproximal bone ...

option in clinical dentistry, requiring proper diagnosis and case selection. Patients present with variable osseous anatomy at the proposed implant location, often making it difficult for the dentist to determine if sufficient bone is present in which to place an implant. Using 2-dimensional radiography (including panoramic, periapical, and bitewing radiographs), which may not allow the dentist...

The purpose of this study was to evaluate clinical outcomes with the use of Resilon root filling in private endodontic practice. This study compared immediate post-operative (IPO) radiographs with at least one year posttreatment, follow up (F) radiographs from 70 randomly selected private practice primary endodontic cases, treated according to a non-standardized protocol but root-filled with Re...

Florid osseous dysplasia (FOD) is an uncommon, benign, cemento-osseous lesion of the jaws. The etiology of FOD is still unknown. It is often asymptomatic and may be identified on routine dental radiographs. The classic radiographic appearance of FOD is amorphous, lobulated, mixed radiolucent/radiopaque masses of cotton-wool appearance with a sclerotic border in the jaws. In our case the lesion ...
