Cemento-ossifying fibroma (COF) is a rare benign fibro-osseous tumor. The radiographic and clini‌cal features of this lesion are unpredictable and variable. In this report, the patient was a 12-year old girl with a painless swelling which demon‌strated an opaque lesion with radiolucent zone to involve left posterior portion of the mandible on panoramic radiography. The radiographic manife‌stati...

Introduction: The use of panoramic radiography has shown a remarkable expansion over the past 20 years. Accurate positioning and preparation of patients is needed to avoid image distortion. The aim of this study was to evaluate the common errors on panoramic radiographs taken in the radiology department of Rasht dental school. Materials and Methods: The study sample included 390 digital panoram...

Nowadays, radiography is a necessary procedure in diagnosis and treatment of patients with dental problems. According to the ALARA (as low as reasonably achievable) principle, dentists must take radiographs of sufficient quality at the lowest possible radiation dose to the patients. The assessment of patient dose on panoramic radiography is difficult because of dynamic nature of the imaging pro...

Growth rate is dependent on genetic and environmental factors and varies between the sexes, between individuals of the same population and between populations themselves. There is strong concern over the dental and bone testing procedures conducted to determine the age of young individuals for legal reasons. Inaccurate results would lead authorities to imprison some children in adult prisons, w...

abstract background and aim: considering the widespread development of implants in dental treatment plans, linear measurements on panoramic radiography are of especial importance. in the present study we investigated the effect of head misalignment up to 15° around vertical and horizontal axes on the magnification rate of digital panoramic radiography in each part of upper and lower jaws. mater...
