    Central giant cell lessions (CGCL) of the jaws in children - The review of 34 cases
    (Taylor & Francis Ltd, 2007) Tamrikulu, R.; Erol, B.; Yilmaz, U.; Yaman, F.; Atilgan, S.
    The aim of this study was to evaluate CGCL in children in regard with age and gender of patients, and location and site of lessions. The study was conducted on 29 cases of CGCG, 4 cases of CGT and one cherubism, which were recovered from the archives of our department by searching the files from 1988 to 2005 for the age group ranging from 4 to 15 years of age. The ratios of the variables under question (occurence, gender location and site) to total cases (percentages), mathematical averages and the statistical comparison of age distribution were used for estimations as the methods of the study. The percentage of CGCL in male 68% is significantly higher than that of female 38%, whereas the occurence of the lessions in mandibula 68% is greater than that of maxilla 29%. Also, the occurence of the tumors in anterior position 57% is higher than that in all the other positions 43%. No significant difference was found among groups for the age distribution. The present data indicates a male predilection and a preponderance of anterior position of mandibula for the studied age group.

    Radiological assessment of elongated styloid process and ossified stylohyoid ligament
    (1996) Erol, B.
    Çalışmamızda, 900 hastadan alınan panoramik grafide uzamış stiloid prosesler ve ossifiye stilohyoid ligamentler radyolojik olarak değerlendirildi. 12 panoramik grafide 30mm.'den daha uzun 16(%80) stiloid proses çift taraflı olarak saptandı ve geri kalan 4'ü(%20) tek taraflıydı. Uzamış stiloid proses sıklığı %1.1 ve ortalama uzunluk 48.15 mm. olarak bulundu. Uzamış bilateral stiloid prosesli bir olgumuz ise semptomatikti.

    A THREE DIMENSIONAL ANALYSIS OF RECONSTRUCTION PLATES USED IN DIFFERENT MANDIBULAR DEFECTS
    (Taylor & Francis Ltd, 2010) Atilgan, S.; Erol, B.; Yardimeden, A.; Yaman, F.; Ucan, M. C.; Gunes, N.; Atalay, Y.
    In this study, the reasons of breaking of the reconstruction plates used in mandibular continuity or mandibular defects were investigated. The study was conducted on 3 cases in which reconstruction plates were used for tumor resection or invasive wound. The objective was to evaluate the mechanical stress in reconstruction plates by means of the finite element method. Three dimensional model of reconstruction plate was exposed to chewing force. A commercial finite element solver (ANSYS) was then applied to this plate to compute the stresses generated in chewing situation. Stress analyses have been carried out by applying Von Mises Yielding Criteria. In the standard reconstruction plate, the results of the finite element analysis revealed that stress resulting from the simulated functional loadings which far exceeded the strengths of the components. The main application of this study was the prediction of fractures as a consequence of known forces. If it was assumed that the patient executes several thousand masticatory movements within a week, a dynamic strain would be present due to the large number of changes in loading, so that there was a danger of a fatigue fracture at the point of the stress concentration (as seen in the analysis), as is also confirmed by clinical practice.
