Sarcoma is a malignant tumor originated from bone, cartilage, fat tissue, nerve, blood vessel, bone marrow, endothelium, etc. and for this reason it exhibits considerable variation not only clinical but histologic appearance. Osteosarcoma occurs chiefly in young persons and in patients older than 40 years it is usually associated with Paget's disease, irradiated bone, multiple hereditary exostosis or polyostotoc fibrous dysplasia and sometimes with preceding trauma. Radiographically it is divided into three forms: an osteoblastic or sclerosing type, an osteolytic type, and mixed type. Histologically it is divided into osteoblastic type, chondroblastic type, fibroblastic type. The treatment of osteosarcoma is radical excision, combined chemotherapy but the prognosis is poor and overall 5-year survival rate is 20-40%. We present two different type sarcomas of 22-year-old male and 56-year-old male patients which we performed surgical excision, combined chemotherapy and radiation therapy.

This study was undertaken to investigate the changes of tooth contacts following orthodontic treatment, using T-Scan system. Occlusal contacts in maximum intercuspation were examined in 26 patients at the end of the active phase of orthodontic treatment and again 3 months into the retention phase to assess the initial posttreatment occlusal changes. The obtained results of this study were as follows: 1. The mean total number of contacts increased from 11.27 at the end of orthodontic treatment to 13.15 at the follow up visit, which was found to be statistically significant (P0.05). 6. The number of post. teeth in contact significantly increased, which was statistically significant (P<0.05). 7. A statistically significant relationship was found between the total number of contacts at the end of treatment and the change in the contacts over time. The fewer the number of tooth contact was at the end of orthodontic treatment, the greater number of tooth contact increased over time(r=-0.38, P<0.05).
