Background: Gonad shielding has been recommended during pelvic x-rays since the 1950s. The popular method of gonad is placement a lead shield in midline pelvis. aim this study was to evaluate prevalence and utility pediatrics undergoing x-rays.Materials MethodsFollowing approval, we retrospectively retrieved data from digital image library ten radiology depertments Khuzestan provience-Iran identify pediatric patients who underwent x-ray (anteriorposterior [AP] view). All images were reviewed...
Nasal septum deviation (NSD) can cause serious anatomical and clinical complications. It change the breathing pattern thus alter anatomy of airway structures. Despite its importance, association between NSD with nasopharynx volume (NPV) has not been assessed before. Therefore, we aimed to investigate it for first time.Archival CBCTs 202 patients older than 17 years without any history trauma or pathology orthodontic/orthognathic treatments were evaluated (129 women, 73 men, mean age: 36.24 ±...
Background Increasing the x-ray film to focus distance (FFD), has been recommended as a practical dose optimization tool for patients undergoing conventional radiological procedures. In previous study, we demonstrated 32% reduction in absorbed is achievable due increasing FFD from 100 130 cm during pediatric chest radiography. The aim of this study was examine whether equally effective other common procedures and performing literature review published studies address feasibility probable...
Background: The use and effectiveness of traditional lead gonad shields in pediatric pelvic radiography has been challenged by several literatures over the past two decades. aim this study was to develop a new radioprotective be radiography. Materials Methods: commercially available 0.06 mm equivalent bismuth garment cropped squarely used as ovarian shield cover entire region pelvis. In order prevent deterioration image quality due beam hardening artifacts, 1-cm foam spacer located between...
Background: Increasing the x-ray focus to film distance (FFD) has been advocated as an effective method reduce patients’ radiation dose. The aim of this study was investigate efficacy technique in patients' dose and image quality pediatric chest x-ray.Material methods: Sixty patients were imaged at FFDs 100 130 cm. Dose measurements performed using thermo-luminescent dosimeters (GR200). images independently assessed anatomical criteria recommended by European guidelines.Results: FFD from cm...
Primary oral melanoma is an uncommon malignant tumor that originates from the proliferation of melanocytes.A 78-year-old man presented with a pigmented lesion around maxillary anterior implant prosthesis. The was excised and diagnosed as melanoma. Biopsy showed neoplasm included dysplastic melanocytes into superficial layers submucosa. Initial testing, including positron emission tomography scan, no metastasis; however, after 7 months, patient developed cervical lymphadenopathy. A neck...
Purpose: The presence of a dental implant across the irradiation beam has potential to perturb dose distribution. In this study, effect different commercial implants on distribution was investigated in electron therapy. Materials and Methods: Varian 2100 C/D linear accelerator (Linac) head modeled precisely with proper components for mode (6 9 MeV) by MCNPX 2.6.1 benchmarked according International Atomic Energy Agency (IAEA) protocol, TRS -398. Dose calculated Six materials, including...
Introduction: this study aimed at determining gender and age by mandibular anatomy landmarks in computed tomography with Cone-Beam (CBCT).
 
 Methodology: cross sectional was performed on 147 CBCT images available archive of radiology the dentistry department Ahvaz Jondi Shapoor medical science university. In research, we assessed parameters including SMEF: Distance from mental foramen to highest point alveolar crest ridge, BIAC: distance lowest IAC most anterior tangent buccal...
Introduction: Paranasal sinuses are four air-filled spaces in face. The maxillary important for dentist because of their location. volume them can be affected by various factors and make prone to sinusitis. Objectives: This retrospective study examined sinus relationship with nasal septum deviation (NSD) using cone-beam computed tomography (CBCT). Materials Methods: From our CBCT archives, we retrospectively selected 210 images 420 healthy sinuses. were calculated the NNT Viewer software...
New cone-beam computed tomography (CBCT) devices are capable of imaging with different resolutions and field views (FOVs), in which higher FOVs impose a dose to the patient. This study was an attempt investigate detection accuracy from horizontal root fractures.Through this experimental study, five (FOV) (voxel size) Tom VGi CBCT (Italy) system used scan fifty teeth fractures half them. The images were evaluated by four observers (two maxillofacial radiologists two general dentists) who...
Background: The ostiomeatal complex (OMC) is not a separate anatomical structure although it functional unit of structures, including the middle meatus, uncinate process, infundibulum, maxillary sinus ostium, ethmoidal bulla, anterior ethmoid and frontal recess. Concha bullosa pneumatization concha, which one most common variations in turbinate. Methods: This study was conducted using cone-beam computed tomography (CBCT) images 172 patients archives Department Oral Maxillofacial Radiology,...
