The only sign of chronic apical periodontitis is periapical lesions that are seen in radiographs. Lesions are visible when the inflammation reaches cortical plates. Lesions located in cancellous bone, cannot be easily seen in radiography. Developing computerized technology in radiography, which has numerous advantages and its show up devices in the market, encourage the clinicians to take advan...

introduction: external root resorption (err) is associated with physiological and pathological dissolution of mineralized tissues by clastic cells and radiography is one of the most important methods in its diagnosis. the aim of this experimental study was to evaluate the accuracy of conventional intraoral radiography (cr) in comparison with digital radiographic techniques, i.e. charge-coupled ...

background radiographs play an integral role in the assessment of periodontal disease. in recent years, advent of digital imaging has revolutionized radiology in dentistry. patients and methods in this diagnostic accuracy study, 48 inter proximal surfaces were evaluated in eight patients. these patients had alveolar bone loss in anterior regions because of periodontitis. intraoral (parallel per...

Abstract Background The aims of this study were (1) to determine the accuracy, sensitivity, and specificity panoramic peri-apical radiographs in diagnosing furcation involvement, as well (2) evaluate possible impact clinical experience on these diagnostic parameters. Methods An existing radiographic dataset periodontitis patients requiring implant surgery was retrospectively examined for involv...

Aim: To evaluate the diagnostic accuracy of panoramic radiography (PAN) for identification infectious foci tooth and periradicular bone before definitive chemo-radiotherapy treatment oropharyngeal cancer, using multislice spiral computed tomography (MSCT) imaging as reference standard. Materials methods: 50 patients with cancer who had performed both pre-treatment MSCT PAN were retrospectively ...

BACKGROUND This study aimed to compare glide path preparation of different pathfinding systems and their effects on the apical transportation of ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland) in mesial root canals of extracted human mandibular molars, using digital subtraction radiography. MATERIAL AND METHODS The mesial canals of 40 mandibular first molars (with curvature angles...

INTRODUCTION The aim of this in vitro study was to evaluate the correlation between accuracy of Root ZX electronic foramen locator and root canal curvature. METHODS AND MATERIALS One hundred and ten extracted mandibular molars were selected. Access cavity was prepared and coronal enlargement of mesiobuccal canal was performed. A #10 Flexofile was inserted into the mesiobuccal canal, and a rad...

Calcium deposited within a root canal due to exogenous stimuli may hamper root canal treatment. In endodontic treatment, an operating microscope allows the conditions within the root canal to be directly viewed and evaluated. This report describes a case in which an operating microscope was used to facilitate the excision of a calcified structure from within a root canal at an early stage in th...

The purpose of the current study was to evaluate noise reduction effect on apical root resorption evaluation in digital radiography. In the present experimental study, 60 extracted lower premolars with sound roots were used. The teeth were fixed in a dry human mandible for radiographic evaluation. Digital radiographs were taken before and after artificial external root resorption on the mesial ...
