Dental nikel krom alaşımına uygulanan altın kaplamanın yüzey pürüzlülüğü ve bakteri adezyonuna etkilerinin incelenmesi

Bu in vitro çalışmada, dental Nikel-krom (Ni- Cr) alaşımından hazırlanan örnekler elektrolitik yolla altın kaplanarak yüzey pürüzlülüğü ve bakteri adezyonu üzerindeki etkileri incelendi. Toplamda 30 adet disk şeklinde Ni-Cr alaşımı örnek hazırlandı ve polisajlandı. Polisajlı örnekler rastgele iki gruba ayrıldı (n=15) ve kaplama işlemi öncesi örneklerin yüzey pürüzlülüğü ölçüldü. Sonrasında gruplardan birine dental uygulamalar için üretilmiş altın kaplama cihazı yardımıyla kaplama işlemi uygulandı ve sonrasında tekrar yüzey pürüzlülüğü ölçümleri gerçekleştirildi. Bakteri adezyon testi için Streptococcus mutans (S.mutans) bakterisi (NCTC 10449) ve koloni sayım yöntemi kullanıldı. Veriler istatistiksel olarak değerlendirildi ve çalışmanın sonucunda, altın kaplama uygulanan grupta hem yüzey pürüzlülüğü hem de bakteriyel adezyon miktarının belirgin bir şekilde azaldığı tespit edildi (p

The investigation of the effects of gold plating applied onto dental nickel- chromium alloy on surface roughness and bacteria adhesion

In this in vitro study, the effect of surface roughness and bacteria adhesion of dental Nickelchromium (Ni-Cr) alloy specimens plated with gold via electroplating were investigated. A total of 30 disc shaped Ni-Cr alloy specimens were prepared and polished. Polished specimens were randomly divided into two groups (n=15) and surface roughness measurement were performed, before plating process. Streptococcus mutans (S.mutans) bacteria (NCTC 10449) and colony counting method was used for bacteria adhesion test. Data were evaluated statistically, and the study suggested that both surface roughness and amount of bacterial adhesion of gold plated group were decreased significantly (p
