Öğe Anatomic variations of nasal cavity and osteomeatal complex(2013) Sümbüllü M.A.; Altun O.; Durna D.; Çakur B.Objectives: The maxillary sinuses are important anatomical structures for dental procedures in dentistry. The normal function of the sinuses is effective in the success of these dental procedures. The continuation of the normal functions of the paranasal sinuses, the maxillary and osteomeatal complex (OMC) has an important role. In this study, we aimed to investigate the frequency of osteomeatal complex anatomic variations with cone-beam computed tomography. Material and Methods: In this retrospective study, in cone-beam computed topographies of 280 patients (154 men, 126 women), anatomic variations of paranasal sinuses (deviated septum, inferior turbinate hypertrophy, concha bullosa, paradoxical middle turbinate, Agger nasi, Haller's cell, Onodi cell, pneumatized uncinate process (uncinate bulla), pneumatized crista galli, pneumatized septum) were analyzed. Results: In our study, septal deviation 85%; inferior turbinate hypertrophy 48.6%; middle concha bullosa 40%; Agger nasi cells 28.6%; Haller's cells 9.6%; pneumatized septum 4.6%; paradoxical middle turbinate 2.5%; pneumatized uncinate process 2.5%; pneumatized crista galli 1.4%; Onodi %1.1 were found. Conclusion: Variations of the osteomeatal complex due to the effect of the paranasal sinuses should be considered in maxillary dental implant planning.Öğe Assessment with radiography of tooth loss and alveolar bone resorption in elderly(2012) Eltas A.; Altun O.; Yavuzer D.; Dedeo?lu N.Objectives: The aim of this study was to determine the oral and periodontal health of elderly people in Turkish population. Materials and Methods: This study include 479 patients that 330 of them were 50-65 (Group A), 149 of them were 65 and over (Group B) years old. Systemic diseases, total number of teeth, number of teeth which has to extract, number of teeth which has to extract with periodontal reasons and frequency of alveolar bone resorption with periodontal reasons was evaluated with clinical examination records and OPT radiographs. Results: Frequency of tooth loss and alveolar bone resorption in group B were higher than group A (p<0.05). Systemic diseases and gender have no significant relation with number of lost tooth and frequency of alveolar bone resorption. Conclusions: It is clear that the data about oral health condition in elderly people is inadequate. Therefore, comprehensive clinical examinations are needed on this issue.Öğe The Comparison of Styloid Processes in the Edentulous and the Posterior Dentate Patients Using Panoramic Radiography(Mashhad University of Medical Sciences, 2021) Dedeoğlu N.; Eşer G.; Altun O.Introduction: The aim of this study was to evaluate the length of styloid processes of edentulous and posterior dentate patients retrospectively using digital panoramic radiography. Methods: This study was carried out in southwestern of eastern Anatolia region Turkish population. In this study, 100 styloid processes of each of edentulous and posterior dentate patients were measured on digital panoramic radiographs. Styloid process longer than 30 mm was evaluated as an elongated styloid process. Recording of data was performed based on gender, side and groups, Chi-square and Mann Whitney U test were conducted for statistical analysis. Results: Styloid process length was not found to be statistically significant between edentulous (24.9±6.66) and posterior dentate (25.75±5.64) groups (p?0.05). The frequencies of Elongated styloid processes were not statistically different between genders, side or groups (p?0.05). Conclusion: Being edentulous was not an important factor for the length of the styloid process and the likelihood of symptoms that might develop. © 2021, Mashhad University of Medical Sciences.

Many methods of age estimation have been suggested. Demirjian method is the most frequently used one of these. In the literature, there is a little known about applicability of this method in Turkish children. The aim of the present study was to evaluate the reliability of Demirjian method of dental age estimaiton and for description of mandibular permanent tooth formation in Turkish children from the southwest Eastern Anatolia region. Materials and Methods: A retrospective study was performed on 1015 panoramic radiographs and 5-15 years of age South western of Eastern Anatolia Regionof Turkish children. The stages of dental maturity of the mandibular left seven permanent teeth for each subject using the eight radiographic dental maturity stages demonstrated by Demirjian's method were evaluated. A pired t-test was used for statistical analysis. Results: The mean difference between the chronological and dental ages ranged 0,28 to 1,10 years in boys and from 0,18 to 0,68 years in girls. South western of Eastern Anatolia Region of/Turkish children were generally delayed in dental maturity compared with children in Demirjian sample. The differences between the chronological and dental ages were statistically significant in 6-6.9, 8-8.9, 9-9.9, 10-10.9, 11-11.9 years in boys and in 8-8.9, 9-9.9,11-11.9 years in girls. Conclusions: Turkish children from the southwest Eastern Anatolia region are significantly more delayed in dental maturity compared to Demirjian's French-Canadian sample. The applicability of Demirjian data is not suitable for Southwestern of Eastern Anatolia Region of Turkish children.Öğe Evaluating root and canal configuration of mandibular molars with cone-beam computed tomography in an eastern region of Turkish population(Cumhuriyet University Faculty of Dentistry, 2014) Ahmeto?lu F.; Altun O.; Şimşek N.; Sinan Ocak M.; Dedeo?lu N.Objectives: The aim of this study was to examine the root canal morphology of mandibular molars using cone beam computed tomography images of individuals living in the East of Turkey. Materials and Methods: The tomographic images of a total 183 patients attending the Oral and Maxillofacial Radiology Department and clinical records were taken between 2011-2013 years were evaluated and clinical records. Root and canal diversities were classified according to the methods created by Vertucci and Gulabivala et al. Results: 173 first molar and 235 second molar teeth were examined among evaluated 155 patients. While the majority of the molar teeth had two separate roots (94.2% of the first molars, second molars 81.7%), three separate roots in first molars and second molars were found respectively 4.6% and 2.1%. Mesial roots of first molars with two separate roots showed type 4 canal configuration rate of 72.4%, whereas distal roots showed type 1 canal configuration rate of 69.3%. The Mesial root of the first molar teeth with three canals showed type 2 canal configuration (62.5%), the distal roots showed completely type 1 canal configuration (100%). The rate of 36% for type 4 canal configuration was detected in mesial roots and the rate of 95.8% for type 1 canal configuration was detected in distal roots of second molars with two canals. Type 1 canal configuration was most prevalent in the three rooted molars. Conclusions: While, two separate roots were most prevalent in each of two teeth groups, three separate roots were seen less frequent. Type 1 canal configuration was most prevalent in the distal roots, whereas the mesial roots had more complex root canal morphology and showed mostly type 4 canal configuration.Öğe Evaluation of anatomical variations of nasal cavity and paranasal sinuses with cone beam computed tomography(Nobelmedicus, 2017) Dedeoğlu N.; Altun O.; Bilge O.M.; Sümbüllü M.A.Objective: The aim of this study is to evaluate anatomical variations of nasal cavity and paranasal sinuses using cone beam computed tomography (CBCT), which is currently used in dentistry radiology. Material and Method: In this study, 251 patients’ nasal cavities and paranasal sinuses were evaluated using CBCT (Newtom 5G, Verona Italy) images in terms of anatomical variations. The high-resolution (voxel and slice thickness: 0.2 mm) multiplanar reformatting images (MPR) were used for the evaluation of the variations. Results: The most common anatomical variation of nasal cavity and paranasal sinuses found in this study was agger nasi cell (95.6%). The most rarely observed variation was sphenoid sinus aplasia (0.8%). There was no statistically significant relationship between concha bullosa and nasal septum deviation. Conclusion: CBCT is a preferred alternative and reliable method for evaluation of anatomical variations of the nasal cavity and paranasal sinuses. © 2017, Nobelmedicus.

Materials and Methods: This retpospective study was carried out using panoramic radiographs of the patients who came to İnönü Univercity Faculty of Dentistry, Departman of Dentomaksillofacial Radiology for dental problems. Results: Among the evaluated of 981 patients, 64 taurodont teeth were found in 31 patients, 8 of them were male (%25.8) and 23 of them were female (74.2%). Ten of cases were hypotaurodont (%15.63), 13 were mesotaurodont (%20.31), 26 were hypertaurodont (%40.62) and 15 cases were pyramidal (%23.44). The maxilla was affected more frequently than the mandible, the most common taurodont tooth was the mandibular 2nd molar. Conclusions: As a result, the prevalence of taurodontism was found to be %3.2.Öğe Rhabdomyosarcoma of the oral cavity: A case report(Dental Investigations Society, 2011) Miloglu O.; Altas S.S.; Buyukkurt M.C.; Erdemci B.; Altun O.Rhabdomyosarcoma (RMS), a tumor of skeletal muscle origin, is the most common soft tissue sarcoma encountered in childhood and adolescence. The common sites of occurrence are the head and neck region, genitourinary tract, retroperitonium, and, to a lesser extent, the extremities. In the head and neck region, the most commonly affected sites are the orbit, paranasal sinuses, soft tissues of the cheek, and the neck. RMS is relatively uncommon in the oral cavity, and the involvement of the jaws is extremely rare. Here, we report a case of oral RMS in a 13-year-old child and describe the clinical, radiological, histopathological, and immunohistochemical findings.
