Accuracy of Assessment of Gonial Angle by Both Hemispheres of Panoramic Images and Its Comparison with Lateral Cephalometric Radiographic Measurements
Professor Yrjo Paatero, in 1961, first introduced the Orthopantomography (OPG) [1]. It has been extensively used in dentistry for analysing the number and type of teeth present, caries, impacted teeth, root resorption, ankylosis, shape of the condyles [2], temporomandibular joints, sinuses, fractures, cysts, tumours and alveolar bone level [3,4]. Panoramic radiography is advised to all patients...
متن کاملComparative analysis of the gonial angle on lateral cephalometric radiographs and panoramic radiographs.
We measured the gonial angle (GA) on panoramic radiography (PR) and analyzed the correlation between the GA on PR and lateral cephalometric radiography (LCR). In total, 49 PR films and LCR films from dentate young adults were evaluated. Orthodontists plotted four points (articulare, menton, posterior gonion, and lower gonion) on the PR and carefully traced them. Using a protractor, two radiolog...
متن کاملAgreement Between Panoramic and Lateral Cephalometric Radiographs for Measuring the Gonial Angle
BACKGROUND The gonial angle is one of the most important measurements required for orthodontic treatment and orthognathic surgery. It is difficult to determine the accurate measurement of each gonial angle on cephalometric radiographs because of superimposition of the left and right angles. OBJECTIVES The aim of the present study was to determine the right and left gonial angles on panoramic ...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
Dilemma of gonial angle measurement: Panoramic radiograph or lateral cephalogram
PURPOSE The purpose of this study was to evaluate the accuracy of panoramic imaging in measuring the right and left gonial angles by comparing the measured angles with the angles determined using a lateral cephalogram of adult patients with class I malocclusion. MATERIALS AND METHODS The gonial angles of 50 class I malocclusion patients (25 males and 25 females; mean age: 23 years) were measu...
