    Clinical and radiographic comparison by analyzed cone beam CT between one stage and two stage dental implants
    (University of Dicle, 2017) Yildirm T.T.; Kaya F.A.; Yokus B.; Colak M.; Ozdemir E.; Tekin G.G.; Saribas E.
    The aim of this study is to evaluate the relationship between the periodontal clinical parameters and alveolar bone loss rate (ABLR) values in one and two stage dental implants using dental tomography A total of 40 dental implant was applied to patients, 20 a one-stage surgical procedure (group I) other 20 two-stage surgical procedure (group II), who had a single missing tooth in the lower jawbone. All clinical measurements were recorded at before loading (T0), after loading at the 3 rd month (T1) and after loading at the 6 th month (T2). Alveolar bone loss rate (ABLR) values were evaluated at T0 and T3 using dental tomography because of minimal artifacts and distortions. In our study, PPD was found to be significantly high in group I than group II at T1 and T2. There was a significant relation between the mPI and ABLR at T2 in Group I, also KSTI and ABLR at T0 in Group II. The data of this study confirms that; one stage surgery procedure PPD is high than two stage surgery procedure. Larger scale studies, particularly in peri-implantitis cases, may shed more light on this subject.

    Investigation of fracture resistance of different core materials
    (2012) Bahşi E.; Colak M.; Atakul F.; Celik M.Y.
    The aim of this study was comparatively investigation of in vitro fracture resistance of four different restorative core materials in endodontically-treated mandibulary premolar teeth. Eighty caries-free human permanent mandibular premolar teeth, freshly extracted because of periodontal or orthodontic reasons were randomly divided into four groups of 20 teeth each. Core restorations were prepared using these core materials: Group 1: Filtek P60 (3M ESPE, USA), Group 2: Clearfil Photo Core (Kuraray Medical Inc., Japan), Group 3: Miracle Mix (GC Corporation, Japan) and Group 4: Vitremer (3M ESPE, USA). Then were subjected to thermocycling 1.000 times with a dwell time of 30 second at 5 ± 2 °C and 55 ± 2 °C. The teeth were loaded in a Universal Testing Machine (TSTM 02500; Elista Ltd. Şti., Türkiye). All the teeth were loaded until fracture was occured. The fracture force (Newton) was recorded for each specimen. The results obtained were statistically evaluated with ANOVA and Bonferroni corrected Mann Whitney U-tests. Statistically, the mean fracture resistance scores among groups (p<0.001) and values of fracture code between Group 1 and Group 4, were significant. The group of Filtek P60 was found succesfull when the values of fracture resistance were examined.
