    Autogenous abdominal fat transplantation into temporomandibular joint following removal of osteochondroma
    (Elsevier Inc, 2018) Tekin U.; Onder M.E.; Bolat I.E.; Atil F.; Kocyigit I.D.; Baris E.
    Background: An osteochondroma (OC) of the condylar process is a rare condition which primarily affects the mandibular condyle. There are several surgical treatment protocols of OC. As effective hemostatic agents and space fillers, autogenous free-fat grafts prevent scar formation and helps to hinder the accumulation of blood and serum, which otherwise, may be replaced by a dense collagen (scar), osteoid or bone. We report the autogenous abdominal fat transplantation, following the removal of a condylar OC. Methods: A 42-year-old man presented with the one-year history of progressive facial asymmetry and deviation of the chin, cross-bite to the contralateral side, and difficulty in mastication. Radiographic and clinical findings confirmed the diagnosis of an OC. Computed tomography (CT) showed lateral and inferior displacement of the right mandibular condyle due to the presence of a bone lesion from the medial aspect of the condylar head. Results: The OC was removed; the remaining portion of the condyle was re-shaped and smoothened. Abdominal fat harvesting was done 2–3 cm below the umbilicus and 3–5 cm length on the transverse midline. The defective area was filled with a harvested autogenous abdominal fat. Conclusion: Our results suggest that autogenous abdominal fat graft placement after the removal of OC with condyloplasty is yielded satisfactory treatment outcomes. © 2018 The Authors

    Malondialdehyde levels and total antioxidant capacity in the dental follicles of the asymptomatic impacted third molars
    (Cumhuriyet University Faculty of Dentistry, 2015) Tekin U.; Kisa U.; Atil F.; Hendek M.K.; Dogan O.; Gurcan S.
    Objectives: Malondialdehyde (MDA), is one of many low molecular weight end products of lipid peroxidation (LPO), increases in oxidative stress. Antioxidants such as total antioxidant capacity (TAC) have a protective effect against reactive oxygen species. The aim of this study is to examine the development of the antioxidant defense mechanism in dental follicles (DFs) of radiologically asymptomatic impacted third molars (ITMs) by using MDA and TAC. Materials and Methods: This study involved 40 DFs of 40 patients referred for clinically and radiographically asymptomatic ITMs. 40 healthy gingival tissues in the same patients obtained during surgical removal of teeth as a control group. This study involved DFs widths on periapical radiographs narrower than 2.5 mm were included in the study. All of tissues samples were analyzed for MDA and TAC. Results: Levels of the MDA and TAC in DFs were significantly higher than the levels of MDA and TAC provided from healthy gingival tissues of the same patients (p<0.05). Conclusions: The results of our study showed that an important antioxidant defense mechanism may also occur in DFs of asymptomatic ITMs. In the light of these preliminary findings of the presented study, supplementary studies should be undertaken to establish the differences between inflammation affecting the DFs and clinical outcomes.
