Effect of using different strips on reducing the most common error in panoramic imaging: A randomised controlled trial on palatoglossal air space shadow

Autor: Andisheh Mokhtari, Sedigheh Razi, Kasra Rahimipour, Tahmineh Razi

Publikováno v: Journal of Medical Radiation Sciences, Vol 71, Iss 2, Pp 194-202 (2024)

Abstract Introduction Panoramic radiography quality can be impaired by some errors such as positioning errors. Palatoglossal air space shadow error is one of the most common positioning errors and it is due to the tongue not sticking to the roof of t

Relationship between Hounsfield Unit in CT Scan and Gray Scale in CBCT

Autor: Tahmineh Razi, Mahdi Niknami, Fakhri Alavi Ghazani

Publikováno v: Journal of Dental Research, Dental Clinics, Dental Prospects, Vol 8, Iss 2, Pp 107-110 (2014)

Background and aims. Cone-beam computed tomography (CBCT) is an imaging system which has many advantages over computed tomography (CT). In CT scan, Hounsfield Unit (HU) is proportional to the degree of x-ray attenuation by the tissue. In CBCT, the

Comparison of Accuracy of Conventional Periapical Radiography and Direct Digital Subtractions Radiography with or without Image Enhancement in the Diagnosis of Density Changes

Autor: Tahmineh Razi, Arezu Mohammadi, Morteza Ghojazadeh

Publikováno v: Journal of Dental Research, Dental Clinics, Dental Prospects, Vol 6, Iss 2, Pp 54-58 (2012)

Background and aims. In periapical radiographic technique, the changes will be visible only after considerable deposition or resorption while digital subtraction technique visualizes slight density changes. This study was aimed to compare visualiza

Comparison of linear dimensions and angular measurements on panoramic images taken with two machines

Autor: Tahmineh Razi, Seyed Hosein Moslemzade, Sedighe Razi

Publikováno v: Journal of Dental Research, Dental Clinics, Dental Prospects, Vol 3, Iss 1, Pp 7-10 (2009)

Background and aims. Panoramic radiography is a method widely used because of low absorbed dose in patients (approximately 10 times less than that in the full mouth survey), reasonable cost and time. Disadvantages of this radiography technique are ma

Comparison of Dimensions of the Palate Between Individuals With and Without Nasal Septum Deviation on Cone-Beam Computed Tomography Images in an Iranian Population

Autor: Fatemeh Nasereslami, Tahmineh Razi, Elham Banakar, Parya Emamverdizadeh, Sedigheh Razi

Publikováno v: Avicenna Journal of Dental Research. 14:160-164

Background: Nasal septum deviation might disrupt the integrity of nasal septum components, resulting in deformity. Such changes might affect the morphology of adjacent structures. The aim of the present study was to evaluate the dimensions of the pal
