Incidence of mandibular fractures in black sea region of Turkey

Background: The aim of this study is to review the incidence of mandibular fractures in the Black Sea Region of Turkey and to present our treatment protocol. Material and Methods: Data were collected regarding age, sex, etiology, time distribution, site of the fracture and the associated injuries and evaluated. These patients were treated at Ondokuz Mayıs University Department of Oral and Maxillofacial Surgery between 2003 and 2010. Data were collected from patient files in the archive and were analyzed using SPSS version 20.0 software. Results: A total of 82 patients with 133 mandibular fractures were included in this study. After the follow up period of the patients, the results were achieved from 58 (70.7%) males and 24 (29.3%) females, whose ages ranged from 5 to 72 years and the mean age was 29. Fractures were most seen in 2008 and the busiest month was August. Falls (40.2%) were the major causes of mandibular fractures followed by traffic accidents and violence. The mandibular anatomical sites of higher fracture incidence were: condyle (34.6%), body and symphysis. The number of the fractures and injuries which were seen in other places such as zygomatic arch, alveolar process, tongue, upper and lower lips, orbita, arms was 14. 53 (64.6%) patients were treated by closed reduction, whereas 13 (15.8%) patients were treated by open reduction. Conclusions: We concluded that our results were widely similar with the studies in developing countries. Socio- economic factors, cultures, geographic conditions and education could affect the etiology of the mandibular fractures and cause different results between the studies conducted in different countries

Yağ dokusu İçeren Nadir Bir Stafne Kemik Kavitesi Olgusu

<p>Stafne bone cavities are firstly reported by Stafne in the angle of mandibles in1942. These cavities are usually located at the lingual side in the area between the mandibular first molar and the mandibular angle, and are not considered rare. They are usually unilateral and casually diagnosed during routine radiographic examination. One of their primary radiological diagnostic features is the characteristic location below the mandibular canal. Because of the diagnostic mixtures between the Stafne bone cavities and other radiolucent lesions, detailed visualization procedures are essential. The Dental Computerized Tomography (DCT) scan is suggested as the most suitable noninvasive diagnostic and follow-up modality for this bony configuration in the posterior mandible. Magnetic Resonans Imagenes (MRI) findings give detailed information to the surgeons about the content of the these cavities.  In this paper, we present a rare case of Stafne Bone Cavity which has fatty content. Its differential diagnosis was carried out with DCT and MRI.</p><p><strong>Keywords:</strong> Stafne bone cavity, adipose tissue, dental computerized tomography, MRI.</p><p> </p><p><strong>ÖZET</strong></p> <p>Stafne kemik kavitesi, 1942 yılında ilk defa Stafne tarafından mandibula angulusunda rapor edilmiştir. Bu kaviteler genellikle mandibula angulusu ve mandibuler birinci molar arasında lingualde lokalizedirler ve nadir oldukları düşünülmez. Genelikle tek taraflı ve rutin radyografik muayene sırasında tesadüfen teşhis edilirler. Radyolojik teşhiste primer özelliklerinden biri de mandibuler kanalın altında karakteristik lokasyonlarıdır.

The assessment of new bone formation induced by unfocused extracorporeal shock wave therapy applied on pre-surgical phase of distraction osteogenesis.

PURPOSE: This study aims to evaluate the effects of extracorporeal shock wave therapy applied before and/or immediately after the osteotomy on the maturation during the consolidation phase. MATERIALS AND METHODS: 21 female New Zealand rabbits were used in the study. Subjects were divided randomly into three groups: Control (Distraction without ESWT), A (Distraction +ESWT After Osteotomy), AB (Distraction+ESWT After and Before Osteotomy). ESWT (500 pulses, 5 Hz, 0.19 mJ/mm2 energy flux density) was applied to group A and group AB after 5, 12 and 19 days after osteotomy and group AB only on days 7,14 and 21 before osteotomy. On the 28th day of the consolidation period, all subjects were sacrificed. Dual-energy x-ray absorptiometry (DEXA) was used to determine bone mineral density (BMD) and bone mineral content (BMC), and stereological methods were used to determine the new bone, connective tissue and neovascularization volumes. RESULTS: As a result of DEXA examinations made on the 1st and 4th week of consolidation, there was no significant difference between groups regarding BMD and BMC values. According to the results of stereological examination, when the connective tissue and new bone tissue were evaluated, higher values were observed in AB when compared to A, and in AB and A compared to the control group, but the differences are not statistically significant. There was no difference between the groups in terms of neovascularization. CONCLUSION: ESWT in these parameters was not positively effective in bone maturation during consolidation when applied before osteotomy or both before and after osteotomy

Akut ve kronik oroantral açıklıkların cerrahi tedavisi: 33 vakalık klinik çalışma

<p>Oroantral comunications are known as pathological connections occuring between the oral cavity and maxillary sinus. Early treatment of this condition prevents the development of sinusitis and fistula, as well as the need for more complex methods of treating patients and the possibility of recurrence. In this study; age, sex, etiologic factors, location of the opening, methods of treatment and early complications of 33 patients that surgically treated in Ondokuz Mayıs University, Faculty of Dentistry, Oral and Maxillofacial Surgery Clinic between 2005-2011 were examined. 18 (54.54%) of oroantral openings were treated with buccal advancement flap, 4 (12.12%) of them were treated with palatal rotational flap, 8 (24.24%) of them were treated with iodoform gauze pack strip and the remaining 3 (9.09%) cases were treated with buccal fat pad, double-tunnel method and primary closure. In all cases, tooth extraction was the only etiologic factor. 100% (20/20) success was achieved in all patients with acute openings, while the rate was 77% (13/10) in patients with oroantral fistula.<strong> </strong></p><p> </p><p><strong>ÖZET</strong></p> <p>Oroantral açıklıklar, ağız kavitesi ve maksiller sinüs arasında meydana gelen patolojik bağlantı olarak bilinmektedir.

Therapeutic effects of caffeic acid phenethyl ester on alveolar bone loss in rats with endotoxin-induced periodontitis.

BACKGROUND/PURPOSE: Caffeic acid phenethyl ester (CAPE) is an antioxidant which is decreases the bone resorption and enhances the bone healing. The aim of this study was to investigate the effects of administering systemic CAPE on alveolar bone loss in rats with experimental periodontitis. MATERIALS AND METHODS: Thirty male Sprague Dawley rats were divided into three groups: control, endotoxin-induced periodontitis (EP), and EP treated with CAPE (EP-CAPE). Endotoxin was injected into the gingiva of test rats on days 1, 3, and 5, whereas saline was injected into the control rats. The EP-CAPE group received 10 mmol/kg/day CAPE intraperitoneally for 28 consecutive days. Saline was given in the control and EP groups in the same manner. At the end of the study, intracardiac blood samples were obtained, and the rats were sacrificed. Alveolar bone loss was analyzed with histometric measurements. The oxidative stress index (OSI) was used to evaluate the oxidative stress. The receptor activator of the nuclear factor kappa B ligand (RANKL) level was analyzed stereologically. RESULTS: CAPE administration significantly decreased the serum OSI and interleukin-1β levels. Alveolar bone loss was statistically higher in the EP group compared with the EP-CAPE group (P < 0.05). Immunohistochemical analyses of the RANKL were significantly lower in the EP-CAPE group than in the EP group (P < 0.05). CONCLUSION: This experimental study revealed that CAPE administration significantly prevented alveolar bone loss and stimulated periodontal tissue healing

Relative Tectonic Activity Assessment of the Cameli Basin, Western Anatolia, Using Geomorphic Indices

Western Anatolia is one of the world's most seismically active regions. A nearly N-S-oriented extension caused the formation of E-W- and NE-SW-trending major grabens, creating the potential for earthquakes with magnitudes5. The fault segments of the NE-trending Cameli Basin were evaluated using geomorphic indices, common tools for assessment of relative tectonic activity in such areas. Quantitative measurement of geomorphic indices including mountain-front sinuosity (Smf; 1.35-2.39), valley floor width-to-height ratios (Vf; 0.080.37), and hypsometric integral (HI; 0.31-1.05) suggest relatively higher tectonic activity along western and southern part of the basin. Hypsometric curves for all segments of the faults mostly exhibit concave or straight profiles, signifying existence of young mountain fronts in the Cameli Basin. These calculations indicate that the Cameli Basin is tectonically active and, southern/south-western areas of this depression have earthquake potential, consistent with epicentres of recent earthquakes, occurred along some fault segments. Possible reason of this activity seems to be related to the E-W-trending corridor lying between the Gulf of Gokova and south-eastern part of the Cameli Basin, represented by active normal faults. These findings should be valid beyond the Cameli Basin for similar situations along the Isparta Angle's western margin.WoSScopu
