Kübra ÖZTÜRK

Odontomas are the most common benign tumors of odontogenic origin. Due to the absence of symptoms, they are usually diagnosed on routine radiographs. Odontomas are divided based on their radiographic, clinical and histological features; compound odontoma and complex odontoma. The region can be reconstructed according to the destruction area of these lesions. Large bone defect in the jaw bone is usually reconstructed with autogenous bone graft from extraoral donor sites. In such cases, anterior iliac grafts are preferred most frequently. We reported 32-yearold man was referred to the Department ...Daha fazlası

The evaluation of the mandibular bone structure changes related to lactation with fractal analysis

Hatice Cansu KIŞ

Objectives Lactation-induced bone loss of lumbar spine, hip, femur and distal radius are well documented in the literature. The aim of this article is to investigate whether lactation afects the trabecular and cortical bone structure of human mandible. Methods 120 dental panoramic radiographs (DPR) of the lactating women who were breastfeeding for 3–6 months (study group) and 120 DPRs of the nulliparous women (control group) were evaluated. Regions of interest (ROI) were chosen from the geometric center of ramus, the geometric center of angulus and the cortical bone. ROIs were examined with fr ...Daha fazlası

Monomer release from nanohybrid composite after bleaching

Özcan KARATAŞ

The evaluation of the effect of bleaching on monomer release from two composite resins was performed by bleaching two nanohybrid composite resins Filtek Z550 and Tetric N-Ceram using two bleaching products Whiteness HP Maxx and Vivastyle. In total, 20 samples were made from each composite resin from which four groups were fabricated (two for each bleaching product). The samples were stored in a 75% ethanol solution, and the solutions were renewed after 1, 7, and 28 days. The monomer release was analyzed using high performance liquid chromatography. The data were analyzed using repeated measure ...Daha fazlası
