INTRODUCTION The aim of this study was to determine in anterior teeth, bicuspids, and molars (1) the accuracy of 3 different electronic apex locators (EALs) in detecting the apical foramen and (2) the accuracy of digital radiography in determining the working length (WL), compared with visible control under a microscope. METHODS By using radiovideography (RVG), we measured the lengths of 120 ...

The determination of the success of endodontic treatment has been often discussed based on outcome obtained by periapical radiography. The aim of this study was to verify the influence of intracanal post on apical periodontitis detected by cone-beam computed tomography (CBCT). A consecutive sample of 1020 images (periapical radiographs and CBCT scans) taken from 619 patients (245 men; mean age,...

OBJECTIVE The aim of the present study was to investigate the correlation between initial alveolar bone density of upper central incisors (ABD-UI) and external apical root resorption (EARR) after 12 months of orthodontic movement in cases without extraction. METHODS A total of 47 orthodontic patients 11 years old or older were submitted to periapical radiography of upper incisors prior to tre...

Integrated positron emission tomography combined with plain computed tomography is commonly employed as the diagnostic tool for patients presenting with lung opacities. This technology is non-invasive and does not put the patient at risk of contrast reaction. We report a case of a man who presented with fever, septicaemia, and a left apical lung opacity on chest radiography. His positron emissi...

The purpose of this study was to investigate digital subtraction technique in digital dental imaging for implant performance, used to quantitatively evaluate bone change around dental implants. For longitudinal assessment of peri-implant bone change, we applied subtraction technique to digital peri-apical radiographs using a digital dental imaging system in two cases at the upper canine and pre...

Neurofibromatosis or von Recklinghausen's disease is the most common inherited syndrome predisposing to neoplasia. Carcinosarcoma is a rare malignant mixed tumor of the lung. Association of carcinosarcoma of lung with Neurofibromatosis-1 is not common. A 57-year-old man presented with history of fever, cough, hemoptysis, breathlessness, weight loss, chest pain. Multiple cutaneous neurofibromas ...

Root fractures can involve the dentin, cementum, and pulp commonly occur as oblique with varying orientations. The aim of this study was to demonstrate maintenance health in a tooth fractured root without any endodontic treatment discuss advantage cone-bean computed tomography (CBCT) compared traditional radiographs diagnosis fractures. Intra-oral radiography 11 revealed horizontal fracture at ...

Objectives: This study aimed to compare the efficacy of panoramic radiography and the buccal object rule in intraoral periapical radiography for localization of impacted maxillary canine teeth. Methods: A total of 20 panoramic radiographs depicting 28 displaced maxillary canines were evaluated. The ratio of the mesiodistal width of the impacted canine to the mesiodistal width of the...
