Ortodontik braketlerin bağlanmasında kendinden pürüzlendirmeli adeziv sistemlerin bağlanma dayanımlarının karşılaştırılması

Bu in vitro çalışmanın amacı kendinden pürüzlendirmeli (self-etch) adeziv sistemlerin bağlanma dayanımlarının karşılaştırılmasıdır. Gereç ve Yöntemler: Bu araştırmada, çekilmiş 100 tane insan üçüncü mandibular molar dişi rastgele 5 gruba ayrıldı (n=20). Her dişe, mezio-bukkal ve disto-bukkal yüzeylerinde olacak şekilde üst birinci premolar braketleri yapıştırıldı (kontrol ve deney grubu). Tüm gruplarda, rastgele seçilen kontrol yüzeyleri total etch sistem ile bondlandı. Deney grubunda, bonding ajanı olarak Grup I'de Transbond Plus SEP (3M Unitek, Monrovia, California, USA); Grup II'de Clearfil S3 Bond Plus (Kuraray Medical, Tokyo, Japan); Grup III'de Clearfil S3 Bond (Kuraray Medical, Tokyo, Japan); Grup IV'de Ortho Solo (Ormco Glendora, California, USA); Grup V'de AdheSE (Ivoclar Vivadent AG, Liechtenstein) kullanıldı. Braketleme sonrası dişler 24 saat 37° C distile suda bekletilip, termal siklus cihazında yapılan 5000 tur sonrasında, hızı 1 mm/dk olan universal test cihazında shear testi yapıldı. İstatistiksel değerlendirme tek yönlü varyans analizi ve Tukey testleri ile yapıldı. Bulgular: İstatistiksel analizler self etch sistemlerin total etch sisteme göre azalan bağlanma dayanımları arasında anlamlı bir fark olduğunu gösterdi (P

Comparison of bond strengths of self etch adhesive systems in orthodontic bracket bonding procedures

The aim of this in-vitro study was to compare shear bond strength (SBS) of the self etch adhesive systems. Methods: 100 extracted human mandibular third molar teeth randomly divided into five groups in this study (n=20). Maxillary first premolar brackets were bonded onto mesiobuccal and disto-buccal surfaces of every molar tooth (control and experimental side). For all groups randomly selected control sides were bonded with total etch system. In experimental side Group I bonded with Transbond Plus SEP (3M Unitek, Monrovia, California, USA); Group II, Clearfil S3 Bond Plus (Kuraray Medical, Tokyo, Japan); Group III, Clearfil S3 Bond (Kuraray Medical, Tokyo, Japan); Group IV, Ortho Solo (Ormco Glendora, California, USA); Group V, AdheSE (Ivoclar, Vivadent AG, Liechtenstein). The teeth were stored in distilled water at 37 °C for 24 hours. After 5000 rounds of thermocycling, SBS test was performed using a universal testing machine at 1 mm/min crosshead speed. Data were analyzed with one way analyses of variance and post-hoc Tukey test. Results: Statistically analysis showed a significantly difference between decreased strength value of self etch adhesive systems according to the total etch (P
