OBJECTIVES The aim of this prospective study was to compare the impact of using two-dimensional (2D) panoramic radiographs and three-dimensional (3D) cone beam CT for the surgical treatment planning of impacted maxillary canines. METHODS This study consisted of 32 subjects (19 females, 13 males) with a mean age of 25 years, referred for surgical(More)
BACKGROUND AND PURPOSE The mastoid portion of the temporal bone has multiple functional roles in the organism, including regulation of pressure in the middle ear and protection of the inner ear. We investigated whether mastoid pneumatization plays a role in the protection of vital structures in the temporal bone during direct lateral trauma. MATERIAL AND(More)
OBJECTIVE We aimed to assess the diagnostic accuracy of different cone beam CTs (CBCTs) and the influence of field of view (FOV) in diagnosing simulated periapical lesions. METHODS 6 formalin-fixed lateral mandibular specimens from pigs were used for creating 20 standardized periapical bone defects. 18 roots were selected for the control group. Three CBCT(More)
This study aims to assess the disk morphology and the condyle position in subjects with temporomandibular (TMJ) disk displacements on sagittal and coronal magnetic resonance imaging (MRI). Seventy-four TMJs (from 37 patients) with positive clinical TMD symptoms according to the RDC/TMD axis I protocol were evaluated by 1.5 T MRI. Disk position, disk(More)
AIMS The main objective of the study was the realisation of an experimental model and evaluation to establish whether the high frequency ultrasound method can supply credible information concerning the structure of the periodontal tissues. MATERIALS AND METHODS We used a 20 MHz, 2D transducer of Dermascan C (CORTEX TECHNOLOGY l) device for examining 20(More)
AIM To identify by ultrasonography (DermaScan C, Cortex Technology1) the reference points necessary to monitor the horizontal bone resorbtion and to assess the accuracy of the measurements by comparing with Cone Beam Computed Tomography images, having direct microscopic section measurements as a gold standard. MATERIAL AND METHODS We performed the(More)
OBJECTIVES The present study evaluated the clinical validity of cone-beam computed tomography (CBCT) scans in comparison to panoramic radiographs regarding preoperative implant planning in combination with sinus grafting procedures. MATERIALS AND METHODS Preoperative assessment of the maxillary sinuses and implant planning using panoramic radiographs and(More)
OBJECTIVES The aim of the study was to establish the changes in posteroanterior cephalometric variables in subjects with temporomandibular joint disorders (TMDs). METHODS Posteroanterior cephalograms of 61 subjects (age range 16-36.6 years, standard deviation 4.88 years) were used to determine cephalometric differences. Subjects were classified according(More)
OBJECTIVES The aim of this study was to evaluate the accuracy of radiological examination methods in quantitative preimplantar bone assessment. MATERIAL AND METHOD The study was carried out on a dry cranium, totally edentate. There have been radiological appreciated the height of the alveolar process and its width, both to the maxilla and the mandible.(More)
