background and purpose: digital radiography has led to many improvements in radiology. despite many advantages there are different ideas in determining anatomical landmarks which results in some errors in cephalometric analyses. the aim of this study was to determine the degree of identification differences of anatomical landmarks by conventional and digital lateral cephalometric techniques usi...
OBJECTIVES The aim of this study was to verify the concordance of the measurement values when the same cephalometric analysis method was used for two-dimensional (2D) cephalometric radiography and three-dimensional computed tomography (3D CT), and to identify which 3D Frankfort horizontal (FH) plane was the most concordant with FH plane used for cephalometric radiography. MATERIALS AND METHOD...
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 ra...
Background. Rocabado’s hyoid triangle is the only cephalometric parameter that can assess the effects of orthodontic treatment on tongue posture. Aim. To evaluate the restoration of tongue posture and function by conducting a cephalometric assessment of the hyoid triangle before and after rapid maxillary expansion. Methods. Sixtyfour healthy patients aged 6-11 years with skeletal class II maloc...

Two auxiliary methods of diagnosing nasopharyngeal airway obstruction were compared. Cephalometric radiography and nasopharyngeal videoendoscopy were evaluated for efficacy in terms of reproducibility and validity. Thirty orthodontic patients (7 to 12 years of age) seeking otorhinolaryngologic treatment for mouth breathing, or mouth and nose breathing, had nasopharyngeal endoscopy and radiograp...
The purpose of this study was to verify the angular measurement values conventional Lateral Cephalometric Radiographs (LCRs) and Cone-Beam Computed Tomography (CBCT) Mid- Sagittal Plane (MSP) projections when using same cephalometric analysis method.
