U.; Kurt, M.; Duran, I.; Uludamar, A.; İnan, O.Objective: To investigate the effects of different acids and etching times on the bond strength of glass fiber-reinforced composite (FRC) posts to composite core material. Method and Materials: Twenty-six FRC posts (FRC Postec Plus) were randomly divided into 13 groups (each n = 2). One group received no surface treatment (control). The posts In the other groups were acid etched with 35% phosphoric acid and 5% and 9.6% hydro- fluoric acid gel for four different etching times (30. 60. 120. and 180 seconds). A cylindric polytetrafluoroethylene mold was placed around the treated posts and filled with dual-cure composite core material (MultiCore Flow). All samples were light cured for 60 seconds. After 24 hours of water storage, the specimens were sectioned perpendicularly to the bonded interface under water cooling to obtain 2-mm post-and-core specimens. Eight specimens were made from each group. Push-out tests were performed at a crosshead speed of 0.5 mm/min using a universal testing machine. Data were analyzed by one-way ANOVA followed by the Tukey honestly significant difference test (ot = .05). Results: The lowest bond strength was observed in the control group (12.51 megapascal [MPa]). No statistical significant difference was observed among group H5-120 (20.31 MPa). group H9-120 (20.55 MPa). or group P-180 (20.57 MPa) (P > .05). These groups demonstrated the highest bond strength values (P < .05). Conclusion: For the FRC posts, all acid-etch- ing procedures tested showed significantly increased bond strength when compared with the control group. Acid-etching with 5% hydrofluoric acid and 9.6% hydrofluoric acid for 2 minutes and with 35% phosphoric acid for 3 minutes (groups H5-120. H9-120. and P-180. respectively) demonstrated the highest bond strength values between the FRC post and composite core material. Although the bond strength was increased by prolonged acid etching, the micro structure of the FRC posts might have been damaged. © 2012 by Quintessence Publishing Co Inc.Öğe Effects on the Clinical Indices and Gingival Crevicular Fluid Enzyme Activities of the Cyclical Regimen of Low-Dose Doxycycline Therapy for Adult Periodontitis.(2000) Alptekin, Nilgün Özlem; Kurtoğlu, Firuze; Serpek, Behiç; Duran, I.; Gözlü, M.The purpose of this study was to determine the effect of cyclic regimen of low dose doxycycline (20 mg) or placebo therapy following scaling and root planing on clinical parameters and crevicular fluid alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and elastase activities. Fifteen adults (13 males, 2 females) with moderate to advanced adult periodontitis were recruited for the study. The LDD-treated group (n = 8 subjects) self administered low dose doxycycline b.i.d. (20 mg, p.o.) from time (treatment) to 2 months and then no drug from 2 to 4 months and finally low-dose doxycycline b.i.d. from 4 to 6 months (i.e. "cyclical" regimen). The placebo-treated group (n = 7 subjects) was asked to take placebo capsules (containing inactive filler; i.e. starchflour) b.i.d. according to the same "cyclical" regimen. No differences were found between LDD- and placebo-treated groups regarding any of the clinical parameters and gingival crevicular fluid enzyme activities. The relative attachment gain was significantly improved in both groups. The "cyclical" regimen of low-dose doxycycline was not found to reduce alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase and elastase activities in gingival crevicular fluid of the adult periodontitis patients over a 6-month time period.Öğe Evaluation of Antibacterial Effectiveness of Desensitizers Against Oral Bacteria(Int Amer Assoc Dental Researchi a D R/a a D R, 2003) Duran, I.; Şengün, A.; Hadimli, Hasan Hüseyin; Ülker, M.; Özer, F.[Abstract not Available]Öğe Relationship between estrogen receptor gene polymorphism and periodontal diseases.(INT AMER ASSOC DENTAL RESEARCHI A D R/A A D R, 2003) Duran, I.; Erdal, M.
