    Evaluation of filling methods applied to some marbles from Diyarbakir region of Turkey
    (Chemical Publishing Co., 2008) Dag A.; Cevheroglu S.; Ayhan M.
    In this study, performance of the filling methods polyester, epoxy and ultraviolet resins applied to two different types of limestone were analyzed. The limestone (sedimentary) used originates from two different types of marble that are widely produced and processed in the Diyarbakir region. The effects of the filling methods on loss of material that occurred during the processing stage and the total process costs were also determined.

    Histological changes in the gingrval tissues of rats subjected to surgical extraction of the adrenal glands
    (2009) Dag A.; Ketani M.A.; Zengingul A.I.; Uysal E.; Baskan Z.
    Hormones are specific regulatory molecules that have potent effects on the major determinants of the development and the integrity of the skeleton and oral cavity also including periodontal tissues. The aim of this study, is to investigate the effect of adrenalectomy on rat gingival tissue. Twenty-eight mature Wistar albino female and male rats divided randomly into 2 groups and in one group adrenalectomy was performed. After 21 days recovery period, Control and Experimental groups were sacrificed under Ketamin HCi anesthesia and clinical and histological observations were made. Microscopic findings, revealed significant changes in adrenalectomized rats. Hypertrophy and thickness of gingival epitelium was apparent in the gingival epithelium of ADX group. Increase in mitotic activity in stratum basale layer of gingival epitelium and increase in keratinisaton layer were observed in adrenalectomized rats. A decrease in collagen fibrils and irregularity of papilla was seen in adrenalectomized rats. Our findings demonstrate the importance of adrenal glands in the development of gingival tissue and suggest that adrenal glands deficiency is one mechanism, by which gingival disorder susceptibility may be increased. © Medwell Journals, 2009.

    The oral findings of the gigantic patient with gingival enlargement-(A case)
    (2009) Kaya F.A.; Saribas E.; Dogru A.G.; Dag A.; Gunay A.
    This syndrome results from a chronic exposure to GH (Growth Hormone) leading to the classic clinical features that the diagnosis seems to be easy. The early diagnosis and intervention may prevent irreversible changes associated with chronic overproduction of GH (as well IGF-1) and may also normalise life expectancy. These patients have an increased mortality rate from systemic sequela of hypersomatotrophism in 2-4 times that of the healthy population. The facial scene changes are generally coarsening of features prognathism and diastema (widely spaced teeth). In this case report it is aimed to represent the periodontal surgery findings of a 24 years old male gigantism patient suffering from gingival enlargement in the site of 11 and 12 teeth who applied to Dicle University Faculty of Dentistry Department of Periodontology. After oral hygiene instruction, initial periodontal treatment was performed and after these the patient was operated. The patients periodic follow ups are still lasting by three months intervals.
