    Adhesion of Two New Glass Fiber Post Systems Cemented With Self-Adhesive Resin Cements
    (MDPI Multidisciplinary Digital Publishing Institute, 2019) Özlek, E.; Neelakantan, P.; Matinlinna, J.P.; Belli, S.; Ugur, M.; Kavut, I.
    The aim of this in vitro study was to evaluate the adhesion strength of two new fiber post systems (FiberSite™ Post and Cytec™ Blanco Post) cemented with two different adhesive resin cements (Panavia™ SA and Maxcem™ Elite). Root canals of sixty extracted human mandibular premolars were prepared using ProTaper Universal™ rotary files (Dentsply Sirona Endodontics, York, PA, USA). The root canals were irrigated with 5.25% sodium hypochlorite (NaOCl) during instrumentation. After root canal preparation, the canals were irrigated with 2 mL of 17% EDTA (1 min), followed by 2 mL of 5.25% (5 min) NaOCI, and 2 mL saline. The root canals were dried with paper points and divided randomly into two study groups (n = 30) according to the type of post system: Group 1, FiberSite™ Post (MegaDental, Partanna, Italy); and group 2, Cytec™ Blanco Post (Hahnenkratt, Königsbach-Stein, Germany), with one of the two adhesive resin cements: Subgroup A, Panavia™ SA Cement Plus Automix (Kuraray, Osaka, Japan); subgroup B, Maxcem™ Elite (Kerr, Orange, CA, USA). Following thermocycling, the adhesion strength was evaluated using the push-out adhesion (bond) strength test. Fractographic analysis was performed using stereomicroscope. The data were analyzed using two-way analysis of variance (p = 0.05). The adhesion strength values of both the posts were significantly higher when cemented with subgroup B (Maxcem™ Elite). The highest adhesion strength value was demonstrated by group 1B (FiberSite™ post cemented with Maxcem™ Elite cement). The type of post did not have a significant impact on the bond strength values for either cement material. © 2019 by the authors.

    Assessment of Buccal Bone Thickness in the Anterior Maxilla: a Cone Beam Computed Tomography Study
    (Cumhuriyet University Faculty of Dentistry, 2019) Koç, A.; Kavut, I.; Uğur, M.
    Objectives: The aim of this study was to evaluate buccal bone thickness by cone beam computed tomography (CBCT) in patients in both genders and in different age groups. Materials and Methods: Our study included 186 anterior teeth and 62 patients with CBCT images. Buccal bone thickness was measured at the crest level, and at a distance 1 and 2 mm apical to the crest level. The t-test and ANOVA test were used in analyzing data. Results: It was found out that age and gender were not significantly associated with the buccal bone thickness of anterior teeth (p > 0.05). The mean buccal bone thickness was the highest as 1.91 mm around the right canines and it was the lowest as 0.35 mm surrounding the right lateral incisor. Conclusions: Our study demonstrated that the mean buccal bone thickness increased towards the apical region for all three teeth types. CBCT precisely measures the maxillary bone thickness and may facilitate the planning process for placing implants and scheduling other types of surgeries correctly. © 2019 Cumhuriyet University Faculty of Dentistry.; Amaçlar: Farkli yaş gruplarindaki ve cinsiyetteki hastalarin bukkal kemik kalinliklarinin konik işinli bilgisayarli tomografi (KIBT) kullanilarak değerlendirilmesi amaçlanmiştir. Gereç ve Yöntemler: çalişmamiza anterior 186 diş ve 62 hastanin KIBT görüntüleri dahil edilmiştir. Kret seviyesindeki, kret seviyesinden 1 ve 2 mm apikaldeki bukkal kemik kalinliklari ölçülmüştür. Elde edilen veriler T testi ve One-way ANOVA testi kullanilarak analiz edilmiştir. Bulgular: Anterior dişlerdeki bukkal kemik kalinliğina yaş gruplari ve cinsiyetin anlamli bir etkisinin olmadiği anlaşilmiştir (p > 0,05). En yüksek ortalama bukkal kemik kalinliği sağ kanin bölgesinde 1,91 mm, en düşük ortalama bukkal kemik kalinliği ise 0,35 mm değerinde sağ lateral kesici bölgesinde ölçülmüştür. Sonuçlar: Sonuçlara göre; her üç diş tipinde de ortalama bukkal kemik kalinliği apikal bölgeye doğru artiş göstermiştir. Maksiller bukkal kemik kalinliğini KIBT ile ölçerek dental implant planlamasinda ve diğer cerrahi operasyonlar hakkinda öngörü sahibi olmak daha kolay olacaktir ve ayni zamanda kesin ölçüm değerleri sağlanabilecektir. © 2019 Cumhuriyet University Faculty of Dentistry.
