Abstract

Aim: The aim of this study was to investigate the effect of three chemical denture cleansers on the Knoop hardness of the acrylic denture teeth. Material and Method: Premolar and molar acrylic denture teeth from two manufacturers were embedded in cold cured acrylic resin. The occlusal surfaces of teeth were flat grounded and polished. The specimens were randomly divided into 4 groups and immersed in three different chemical disinfection (Protefix, Corega Tabs and %1 NaOCl) and distilled water (Control group) for 8 hours/day during 7 days. The specimens were submitted to Knoop hardness measurements procedures. Data were analyzed with one way ANOVA and Tukey’s statistical test. Result: All Vitapan group exhibited higher Knoop hardness values than Major Dent groups both in control and experimental groups. The tested chemical denture cleaning methods did not show any significant effect on Knoop hardness of the artificial teeth. Conclusion: Within the limitations of this study it can be concluded that exposure of artificial teeth to chemical disinfectants did not affect the hardness of the acrylic teeth

KİMYASAL TEMİZLEYİCİLERİN AKRİLİK DİŞLERİN YÜZEY SERTLİKLERİNE ETKİSİ

Abstract

Amaç: Bu çalışmanın amacı 3 farklı kimyasal protez temizleyicisinin akrilik dişlerin yüzey sertliğine etkisini araştırmaktır.

Materyal ve Metod: İki farklı markaya ait akrilik takım dişlerin premolar ve molar dişleri soğuk akrile oküzal yüzeyleri üstte kalacak şekilde gömüldü. Dişlerin oklüzal yüzeyleri zımpara ile düzleştirildi ve polisajlandı. Hazırlanan örnekler üç farklı kimyasal temizleyici (Protefix, Corega Tabs ve %1 NaOCl) ve kontrol grubu olarak distile su içerisine tesadüfi olarak yerleştirildi. Test örnekleri kimyasal temizleyicilere günde 8 saat olmak üzere bir hafta boyunca maruz bırakıldı. Bu sürenin sonunda örnekler Knoop sertlik testine tabi tutuldu. Verilerin istatiksel analizleri tek yönlü ANOVA ve Tukey testleri kullanılarak gerçekleştirildi.

Bulgular: Vitapan dişlerin Knoop sertlik değerleri tüm gruplarda Major Dent gruplarına göre yüksek bulundu. Çalışmada test edilen kimyasal temizleyicilerin protez dişlerinin Knoop sertlik değerlerinde istatistiksel olarak anlamlı değişikliklere neden olmadığı görülmüştür.

Sonuç: Çalışmanın sınırları içerisinde test edilen kimyasal temizleyicilerin test edilen akril dişlerin yüzey sertliklerine negatif etkisinin olmadığı gösterilmiştir.
