چکیده

introdouction: the aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. materials and methods: in this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. implant diameter and length were measured on panoramic radiographs and the horizontal and vertical magnification rates of each placed area were calculated based on the length and width of the placed implant. a twoway anova test was used to evaluate the magnification rate in regard to implant location and gender. results: the range of the magnification factor of the width was 111.09–126.02, which was lowest in the maxillary molar region and greatest in the mandibular anterior region. while the lowest magnification value of the length (111.58) was observed in the mandibular molar region, the highest value (116.09) appeared in the maxillary premolar area. hence, there were no significant differences in image magnification with regard to anatomical site and gender. conclusion: digital panoramic radiography can be reliably used for pre-implant evaluation in various anatomical sites of the jaws in both genders.

Image quality enhancement in digital panoramic radiograph

One of the most common positioning errors in panoramic radiography is palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to the pati...

Quality comparison of direct digital panoramic radiography and computed radiography panoramic

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

Effect of Head Misalignment in Horizontal & Vertical Dimensions on the Magnification Rate of Digital Panoramic Radiography in Different Parts of the Jaws

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. Materia...
