Fibrous dysplasia is a benign fibroosseous bone dysplasia that can involve single (monostotic) or multiple (polyostotic) bones. Monostotic form is more frequent in the jaws. It is termed as craniofacial fibrous dysplasia, when it involves, though rarely, adjacent craniofacial bones. A 16-year-old girl consulted for a painless swelling in the right posterior mandible for two years. Panoramic radiography revealed ground-glass ill-defined lesions in the three different regions of the maxilla and mandible. Axial CT scan (bone window) showed multiple lesions involving skull base and facial bones. Despite lesions in the skull base, the patient had no abnormal neurological findings. The lesion was diagnosed as fibrous dysplasia based on radiological and histopathological examination. In this paper, CT findings and differential diagnosis of CFD are discussed. CT is a useful imaging technique for CFD cases.

An arteriovenous malformation (AVM) is composed of abnormal communications between arteries and veins without the normal intervening capillary bed. AVM of the head and neck is a rare vascular anomaly. We present here an unusual case of AVM with the size of 4x3 cm at the left posterior palatal area. Incisionel biopsy revealed AVM. Resection of the lesion following angiography was suggested to the patient however, he refused the treatment. The patient was considered to be under control. AVM should always be kept in mind in the differential diagnosis of palatal swellings.

Background/purpose: Shovel-shaped incisors are teeth with thick marginal ridges surrounding a deep lingual fossa. They have a higher prevalance in Asian racial groups. In this study, we aimed to find the incidence of shovel shaped incisors in Turkish population, distribution of them according to teeth and sex, and to show the relationship between SSI and the other morphological changes. Materials and methods: The study was carried out on 3960 women and men. Shovel-shaped incisors were detected on 437 individuals. Photographic images of the palatinal surfaces were obtained and after the examiantion of high resolution digitalized images by two observers, teeth of 400 individuals were diagnosed as shovel-shaped. Teeth were classified as “Trace shovel” (type I), “semi shovel” (type II), and “shovel-shaped” (type III) according to the Hrdlicka's scale. the results were analyzed with Chi-square (χ2) test. Results: Prevalence was 10.1%. Shovel-shaped incisors were found in both central incisors and lateral incisors of 273 individuals (68.5%), solely in lateral incisors of 119 individuals (29.5%), and in both maxillary central and lateral incisors and canines of 8 individuals (2%). Shovel-shaped incisors were present in the teeth of 228 women and in the teeth of 172 men (P = 0.015). The majority of the inisors were showing Type II severity (in the central-lateral incisor group 127 individuals, in the lateral group 71 individuals (P= 0.013). Thirty-four accompanied dental anomalies were dens in dente, Talon cusp, peg-shaped laterals, microdonty, and cingulum hypertrophy. was 34. Dens in dente constituted the majority (n = 23, ratio = 67.6%). Conclusion: The incidence of shovel-shaped incisors was 10.1% in our study group; SSI affected lateral incisors more than central incisors; the number of women reflecting SSI was higher than men; and the majority of individuals had Type II (semi-shovel) severity.

Reflections of the invention of W.C. Roentgen reached Turkey in a very short period of time. In the field of medicine, Captain Dr. Esat Feyzi and Captain Dr. Rifat Osman were the first who utilized X-rays in Turkey. Just after the invention of X-rays, the first intraoral radiograms were obtained by Otto Walkhoff and Wilhelm Koenig in Germany and by Frank Harrison in England. The first dental radiology department in Turkey was founded in the Istanbul Darülfünunu Dişçi Mektebi (Istanbul University Faculty of Dentistry) in 1927. Also, dental radiology education started at that time. The first book about radiology was written in 1928, which also was contained information about dental radiology. The first dentist whose profession was radiology was Galip Abdi Rona in Turkey. Rona also presented a paper and made radiology presentations in the first Turkish dental congress between 1 and 5 November 1932. In the beginning of the 1980s, radiology became an independent dental department. Today, in Turkey, there are about 45 dentistry faculties who have radiology departments. A lot of state-of-the-art devices are used not only in faculties but also in private clinics.
