Aim: This study compared the stress distributions of endodontically treated tooth restored with carbon and titanium post under thermal and mechanical loading conditions. Methodology: A 3-dimensional finite element model was created to represent in a labiolingual cross-sectional view of an endodontically treated maxillary central incisor tooth with its supporting structures. It was modified according to two post systems with different physical properties consisting titanium, and carbon fiber. Stress distribution and stress values were then calculated by considering the three dimensional von Mises stress criteria. Results: A 100-N static vertical occlusal load was applied on the node at the center of occlusal surface of the tooth. The von Mises stress values for carbon post model was on the coronal third and the cervical area of the root in the range of 436,16 and 3,59 MPa,  for titanium post model was 590,55 and 3,05 MPa. Thermal stress values for carbon post model showed that maximum stress concentrations were noted on the coronal third and the top of the post area of the root in the range of 509,94 and 6,38 MPa. Titanium post model showed that maximum stress concentrations were noted on the coronal third and top of the post area of the root in the range of 1165,06 and 3,06 MPa. Conclusion: This study shows that the titanium post yields larger stresses than the carbon post under thermal conditions.  How to cite this article:  Adıgüzel Ö, Yiğit Özer S, Bahşi E, Yavuz İ.

Body dysmorphic disorder (BDD) is an obsessive preoccupation with a perceived defect in one’s physical appearance for which the individual persistently seeks medical attention and surgical correction. This preoccupation can be persistent and pervasive, leading to social withdrawal.  A dentist may be the first health care worker who has an opportunity to intervene and assist these people in getting treatment. Patients may have unrealistic expectations for certain procedures, so assessing their psychological status is an important part of treatment planning and diagnosis. Patient expectations should be determined, and the ability to provide care that meets those expectations should be discussed. In the case reports, aesthetic treatments with composite resin restorations of three patients with BDD are reported. The cases highlight the need for dentists to be educated on this disorder so that they can recognize and refer accordingly. There is also a need for interdisciplinary interactions between the dentist and the psychologist. How to cite this article:  Sezgin Bolgül B, Ağaçkıran E, Tümen EC, Ayna Y, Çelenk S, Ayna B.

method for treating mandibular prognathism, distraction osteogenesis (DO) of the maxillary complex is an alternative approach. Methodology: The clinical and radiological examinations of a 29-year-old male revealed maxillary retrognathism and mandibular prognathism without a vertical abnormality. The patient was treated with maxillary advancement by DO and mandibular setback surgery. Results: Long-term functional muscle exercises were scheduled. No relapse has occurred. Conclusions: We believe that the patient’s cooperation and commitment to the functional exercise program played the most important role in the long-term success.  How to cite this article:  Apaydın A, Yenigün S, Can T.

Periodontitis and gingivitis, a prevalent oral diseases, have been connected to several systemic health changes. The aim of this investigation was to review the effects of menopause on periodontal tissue. Epidemiologic studies have identified a number of risk factors and risk indicators for periodontal attachment loss, including demographic, socioeconomic, behavioral, genetic, and systemic factors. Menopause has also been associated with destructive periodontal disease in older women. The homeostasis of the periodontium involves complex multifactorial relationships. Oestrogen and progesterone are responsible for physiological changes in women at specific phases of their life. Menopause is associated with significant adverse changes in the orofacial complex.  How to cite this article:  Talo Yıldırım T, Acun Kaya F. The Effects of Menopause on Periodontal Tissue.
