Introduction & Objective: Diagnosis of periodontal osseous lesions is very important in deter-mining prognosis, treatment plan and maintenance in the long term. This diagnosis can be achieved by using radiography. The aim of this study is to compare accuracy of E speed films, bitewing PSP, panoramic PSP and CCD for identifying the extent of destruction of alveolar bone in chronic periodontiti...
The bifid mandibular condyle is a rare anomaly. A variety of causes are implicated with its development such as developmental origin and trauma. Because of the lack of epidemiological data, there is little information about the real incidence of this malformation. The purpose of this paper is to report a case of bifid mandibular condyle in a 20-year-old woman who referred to a private radiologi...
Background: Pneumatized air cells present in the zygomatic process of the temporal bone are termed Zygomatic Air Cell Defects (ZACDs). They are merely the extensions of the mastoid air cells anteriorly into the zygomatic process of the temporal bone which are important for surgical perspective. Panoramic radiography is useful to display these zygomatic air cell defects. Aim: This study was unde...
One of the most common positioning errors in panoramic radiography is the 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 to be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to t...
The purpose of this study was to compare the physical imaging properties of three kinds of imaging plates (IPs) used with two photostimulable phosphor systems for dental radiography: HR-V, used with the Digora, BAS-SR, and ST-V, used with the DenOptix for intraoral radiography and panoramic radiography, respectively. Sensitivity to X-ray, gradient, modulation transfer function (MTF), noise powe...
Received: 19 Mar 2014 Accepted: 9 Oct 2014 Abstract Background and Aim: To estimate the age in forensic identification, when none of the other identification methods are feasible, the teeth are used. The aim of the present study was to estimate the age from pulp/tooth area ratio (AR) by digital panoramic radiography in patients referred to a radiology clinic. Materials and Methods: In this diag...
