Asidik maddelerin farklı dental porselenlerin yüzey özellikleri ve iyon çözünürlüğü üzerindeki etkinliğinin değerlendirilmesi

Gı̇rı̇ş ve Amaç: Bu çalışmanın amacı; asidik ajanların dental porselenlerin iyon salınımı ve yüzey özellikleri üzerine etkinliğini araştırmaktır. Yöntem ve Gereçler: 3 porselen tipinin her birinden 50 adet olacak şekilde diskler oluşturulmuştur. Porselen diskler 5 farklı saklama ajanında bekletilmiştir. Batırma işlemi sona erdikten sonra tüm sıvı kompozisyonlar, ICP-MS (İndüktif Eşlemeli Plazma - Kütle Spektrometresi) cihazında iyon çözünürlüğü açısından değerlendirilmiştir. İşleme alınmış olan diskler ESEM (Çevresel Tarama Elektron Mikroskobu) altında yüzey özellikleri açısından değerlendirilmiştir. Bulgular: Vita VM 13, IPS Empress ve e.max Ceram porselenlerinin Al iyonu salınım değerleri; vişne suyu ve limon suyu gruplarında istatistiksel olarak anlamlı derecede farklı bulunmuştur (p=0,012; p

Evaluation of the effect of acidic agents on ion leaching and surface characteristics of different dental porcelains

Introduction: The purpose of this study is to evaluate the effect of acidic agents on ion leaching of dental porcelain. Methods: Fifty discs were fabricated from 3 different types of porcelain. All porcelains were immersed in 5 liquid agents. Ion leaching was measured with an inductively coupled plasma – mass spectrometer. Surface characteristics of specimens were examined using environmental scanning electron microscopy. Results: Al ion leaching values of Vita VM 13, IPS Empress and e.max Ceram porcelain were significantly different in cherry juice and lemon juice groups (p = 0,012; p
