OBJECTIVES To systematize the clinico-radiological symptoms and course of bisphosphonate-related osteonecrosis of jaw bone and toevaluate the diagnostic potential of various radiological techniques to detect mild osteonecrosis in each stage of the disease. MATERIAL AND METHODS The sample consisted of 22 patients previously diagnosed with extraoral malignant disease. Diagnosis was based on a c...
BACKGROUND Current technological advances have allowed application of different study designs and techniques for investigation of dental anatomy. Some clinical studies have provided evidence that Cone Beam computed tomography (CBCT) scanning is an important resource in assessment of root canal systems notably to identify MB2 canals in maxillary molars as CBCT scans allow in vivo dental investig...
مقدمه و هدف: بررسی کیفیت استخوان قبل از درمان کاری است حیاتی لذا هدف از این مطالعه ارزیابی کیفیت استخوان با میزان دانسیته حاصل از توموگرافی کامپیوتری با اشعه مخروطی (cone-beam computed tomography cbct) و تعیین رابطه بین دانسیته استخوان و ثبات اولیه ایمپلنت های دندانی می باشد. روش کار: در این مطالعه تجربی آزمایشگاهی 32 ایمپلنت در استخوان تازه گوسفند قرار داده شد. دانسیته استخوانی محل های دریافت ...
Cone beam computed tomography (CBCT) is the modern third dimension applied in the field of oral maxillofacial region. With lower radiation dose compared to conventional CT, its applications in dentistry has increased tremendously. Artefacts can seriously degrade the quality of computed tomographic (CBCT) images, sometimes to the point of making them diagnostically unusable. To optimize image qu...
Introduction: Cone-beam CT (CBCT) is an imaging system which offers three-dimensional (3D), multiplanar images and has many advantages over computed tomography (CT) including shorter acquisition times for the resolution desired in dentistry, lower radiation dose to the patient, reasonable price and higher spatial resolution but CBCT scanners are unable to display actual Hounsf...
Accurate and early diagnosis of vertical root fractures (VRFs) is imperative to prevent extensive bone loss and unnecessary endodontic and prosthodontic treatments. The aim of this study was to assess the effect of time lapse on the diagnostic accuracy of cone beam computed tomography (CBCT) for VRFs in endodontically treated dog's teeth. Forty-eight incisors and premolars of three adult male d...
This study aimed to describe the imaging aspects of a concha bullosa discovered incidentally by means cone-beam computed tomography (CBCT) imaging. A female patient underwent CBCT exam, and bilateral extensive pneumatization middle was verified, presenting larger dimension right side deviated septum. The reported nasal obstruction loss smell. for covering maxillofacial region allowed discovery ...
Introducción: Una de las dificultades los tratamientos endodónticos son variaciones anatómicas raÃces y sistema canales radiculares. Existe poca información sobre prevalencia distribución espacial estas en casos reportados con CBCT (del inglés Cone-Beam Computed Tomography). El propósito la presente revisión fue analizar primer segundo molar permanente mandibular tratamiento endodónti...
The objective of this study was to assess and compare the organ and effective doses in the knee area resulting from different commercially available multislice computed tomography devices (MSCT), one cone beam computed tomography device (CBCT) and one conventional X-ray radiography device using MOSFET dosemeters and an anthropomorphic RANDO knee phantom. Measurements of the MSCT devices resulte...
UNLABELLED Cone-beam CT is an exciting development in dental and maxillofacial imaging. This article gives an overview of the subject and discusses some of the implications for dental practitioners. CLINICAL RELEVANCE Dentists should be aware of technological advances that potentially are going to have major implications on their practice. They should have knowledge of the indications, limita...
