Abstract

Objective: This study aimed to investigate the effect of hydrothermal aging and various plaque removal methods, which are a part of professional dental cleaning, on zirconia’s structural properties. Materials and Methods: Seventy-two disk-shaped monolithic zirconia specimens (diameter 12 mm and thickness 1 mm) divided into six groups were subjected to no surface treatment, instrumentation with steel curette and ultrasonic steel scaler, and air abrasion with sodium bicarbonate, erythritol, and glycine before being aged in an autoclave at 0.2 MPa and 134 °C for 2 h. Specimens were analyzed using X-ray diffraction, scanning electron microscopy with energy dispersive X-ray spectrometry, and atomic force microscopy to evaluate crystal structure, microstructure, and surface roughness. Further, the contact angle and Vickers hardness measurements were performed for wettability and hardness evaluations. A biaxial bending test was applied to measure the durability of the material. Results: According to the results, no significant change was found in the crystal structure, surface roughness, and bending strength of zirconia (p>0.05). In contrast, a substantial decrease in surface hardness values and a significant increase in wettability values were observed in the steel curette and ultrasonic steel scaler groups compared with other groups (p

Özet

Amaç: Bu çalışma, profesyonel diş temizliğinin bir parçası olan plak uzaklaştırma yöntemleri ile hidrotermal yaşlanmanın zirkonyanın yapısal özelliklerine etkisini araştırmayı amaçlamıştır. Gereç ve Yöntemler: Altı gruba bölünmüş 72 adet disk şeklinde monolitik zirkonya örnek (çap 12 mm ve kalınlık 1 mm) otoklavda 0,2 MPa ve 134 °C’de 2 saat hidrotermal yaşlandırma öncesi çelik küret, ultrasonik çelik kazıyıcı, sodyum bikarbonat, eritritol ve glisin abraziv toz ile yüzey işlemine tabi tutuldu. Örnekler, kristal yapıyı değerlendirmek için X-ışını kırınımı yöntemi, mikro yapı için taramalı elektron mikroskobu ve yüzey pürüzlülüğü için atomik kuvvet mikroskobu kullanılarak analiz edildi. Ayrıca ıslanabilirlik ve sertlik değerlendirmeleri için temas açısı ve Vickers sertlik ölçümleri yapıldı. Malzemenin dayanıklılığını ölçmek için ise çift eksenli bükme testi uygulandı. Bulgular: Sonuçlara göre zirkonyumun kristal yapısında, yüzey pürüzlülüğünde ve eğilme dayanımında önemli bir değişiklik olmadığı görüldü (p>0,05). Çelik küret ve ultrasonik çelik kazıyıcı gruplarında diğer gruplara göre yüzey sertlik değerlerinde önemli düşüş ve ıslanabilirlik değerlerinde anlamlı artış gözlendi (p
