The aim of this study was to identify the potential projection errors of lateral, postero-anterior (PA) and submentovertex (SMV) cephalometric radiographs due to head rotation in the vertical z-axis. For this investigation, a complete human dry skull of an adult was used. The skull was rotated from 0 to +/-14 degrees at 2 degree intervals. A vertical axis, the z-axis, was used as the rotational...

OBJECTIVES Contemporary dental radiology offers a wide spectrum of imaging methods but it also contributes to an increase in the participation of dental radiological diagnosis in the patient's exposure to ionizing radiation. The aim of this study is to determine the absorbed doses of the brain, spinal column, thyroid and eye lens for patients during panoramic radiography, cephalometric radiogra...

OBJECTIVES The aim of this study is to investigate the correlation between 2-dimensional (2D) cephalometric measurement and 3-dimensional (3D) cone beam computed tomography (CBCT) measurement, and to evaluate the availability of 3D analysis for asymmetry patients. MATERIALS AND METHODS A total of Twenty-seven patients were evaluated for facial asymmetry by photograph and cephalometric radiogr...

Lateral cephalograms in orthodontic practice display an area cranial of the base of the skull that is not required for diagnostic evaluation. Attempts have been made to reduce the radiation dose to the patient using collimators combining the shielding of the areas above the base of the skull and below the mandible. These so-called "wedge-shaped" collimators have not become standard equipment in...

Objective: The present study is an attempt to develop a method to determine sex from the skull with lateral cephalometric radiograph using discriminant function analysis. Study design: The superciliary ridges, frontal sinuses, sella, cranial base and mastoid process were adopted as objects of lateral radiographic cephalometric measurements. The present study included cephalometric radiographs o...

Cephalometric radiography is the most significant tool for improving taxonomy, communication and analysis of dentofacial variation, as in orthodontic evaluation and treatment, analysis of craniofacial morphology is essential. Steiner's analysis was used in this study; because its methods of assessing skeletal and dental morphology are very useful and valid providing maximal clinical information...
