BACKGROUND/OBJECTIVE Panoramic radiography has a great place among imaging techniques because of its enormous advantages. One of the characteristics of an ideal imaging technique is to supply precise measurement. The purpose of the current study was to evaluate the accuracy of linear measurements of the jaws on panoramic radiographs. PATIENTS AND METHODS In this study, the vertical distances ...
AIM To report a small intaalveolar ameloblastoma which resembled cystic lesion, and to emphasize the value of Computed tomography (CT) in radiographic examination. BACKGROUND Ameloblastoma is a slow-growing, locally invasive odontogenic neoplasm that accounts for approximately 10% of all tumors detected in the jaws. Radiographically, those tumors are usually well-defined. Computerized tomogra...
Endoscopic-endonasal extraction of an ectopic tooth located in the left nasal cavity – a case report
We report the case of a sixteen-year-old female patient with an ectopic intranasal tooth located in inferior nasal meatus left side. The was incidental finding on dental panoramic x-ray, made at orthodontist to plan fixed retainer. didn’t have any symptoms like obstruction, discharge or epistaxis. After discussing our collegues from maxillofacial surgery-department, removed endoscopic-endonasal...
background and aims: tooth displacement changes the periodontium. the aim of orthodontic treatment was desired tooth movement with minimum side effects on the alveolar bone quality. the aim of the present study was to assess changes of alveolar trabeculation among children, youth and adults and the two genders. materials and methods: in this cross-sectional study, 63 patients who had been treat...
BACKGROUND Recent studies suggest that tonsilloliths are clinically related to halitosis and tonsillar abscess. Based on our empirical knowledge, tonsilloliths are relatively commonly encountered in daily clinical practice. It has been reported that the detection rate of tonsilloliths was under 24% in previous reports, although experience suggests otherwise. The purpose of the study was to eval...
PURPOSE The purpose of this study was to investigate the level of clinical image quality of panoramic radiographs and to analyze the parameters that influence the overall image quality. MATERIALS AND METHODS Korean dental clinics were asked to provide three randomly selected panoramic radiographs. An oral and maxillofacial radiology specialist evaluated those images using our self-developed C...
We aimed to establish a reliable method of localizing an impacted maxillary canine on the sole basis of assessment of a single panoramic radiograph, and to determine the validity and reproducibility of the method. Panoramic radiographs of 50 subjects with a total of 68 impacted canines were analysed. The Canine Incisor Index (CII), Canine Canine Index (CCI), control Canine Incisor Index (c-CII)...
A 45-year-old female was referred to the Department of Oral and Maxillofacial Surgery with the complaint of pain in the right submandibular region and a dry mouth, which had started one week previously. A clinical examination revealed a swelling and tenderness in the right submandibular region. Panoramic radiography and computed tomography identified a sialolith in the submandibular gland. Surg...
Methods: Twenty dry human hemimandibles were examed by using periapical and panoramic radiography, and computed tomography. An electronic digital caliper was used to measure the tracings obtained from the radiographies in three different times (groups A1, A2 and A3) and in the cross-sectioned hemimandibles (group B). Measurements consisted of: Measure 1 – from the upper limit of the alveolar ri...
PURPOSE Zygomatic air cells (ZAC) are a variant of temporal bone pneumatization that needs no treatment. However, ZAC can have an impact on surgical procedures in the temporo-mandibular joint region. Recent reports suggest that computed tomography will disclose more ZAC than can be diagnosed on panoramic radiography. The aim of this study was to analyze ZAC prevalence on CT in a population that...
