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...

The aim of this study was to evaluate the accuracy of imaging methods for detection of apical periodontitis (AP). Imaging records from a consecutive sample of 888 imaging exams of patients with endodontic infection (1508 teeth), including cone beam computed tomography (CBCT) and panoramic and periapical radiographs, were selected. Sensitivity, specificity, predictive values, and accuracy of per...

This study investigated the accuracy of diagnosing periapical lesions through conventional radiography (CR) and direct digital radiography (DDR) technique. A total of 170 patients with clinically suspected periapical pathosis and 30 normal subjects were included in the study. Both the conventional and digital images were taken with same exposure parameters keeping the film without lead foil and...

PURPOSE The purpose of this review is to evaluate the possibility of panoramic radiography as a national oral examination tool. MATERIALS AND METHODS This report was carried out by review of the literatures. RESULTS Panoramic radiography has sufficient diagnostic accuracy in dental caries, periodontal diseases, and other lesions. Also, the effective dose of panoramic radiography is lower th...

Traumatic injuries commonly affect the anterior teeth leading to slow death of the pulp. This may give rise to a periapical or radicular cyst which results from the proliferation of cell rests of Malassez following pulpal necrosis of a nonvital tooth. This condition is usually asymptomatic but can result in a slow-growth tumefaction in the affected region. On radiography the lesion can be seen ...

OBJECTIVE To evaluate the periapical repair after root canal treatment in the teeth of dogs using CT and conventional radiography and to compare these findings with the gold standard microscopic evaluation. STUDY DESIGN The animals were divided into three groups according to endodontic treatment performed: Group 1, single-visit endodontic treatment in teeth without apical periodontitis; Group...

Indications for the most frequently used imaging modalities in implant dentistry are proposed based on clinical need and biologic risk for the patient. To calculate the biologic risk, the authors carried out dose measurements. They demonstrated that the risk from a periapical radiograph is 20% of that from a panoramic radiograph. A panoramic radiograph and a series of 4 conventional tomographs ...

OBJECTIVE To compare intraoral periapical radiography with 3D images for the diagnosis of periapical pathology. STUDY DESIGN Maxillary molars and premolars and mandibular molars with endodontic problems and examined with periapical radiographs and a 3D technique (3D Accuitomo) were retrospectively selected and evaluated by 3 oral radiologists. Numbers of roots and root canals, presence and lo...
