Abstract

The purpose of this study was to assess whether three commercial denture cleaners affected the auto-polymerized polymethyl methacrylate (PMMA) resins' flexural strength and elastic modulus during different immersion times. Bar-shaped specimens (2x2x25 mm) were fabricated from auto-polymerized PMMA and subjected to three-point bending tests to assess their flexural properties. The specimens were immersed in three denture cleansers (Aktident, Corega, and Protefiks) for durations of 3 minutes, 15 minutes, and 8 hours, following the manufacturers' guidelines. Flexural strength and elastic modulus were measured using a universal testing machine per ISO 20795-1:2013 standards. Statistical analysis was performed using SPSS software, with significance set at α = 0.05. Immersion significantly impacted the flexural properties of PMMA. Short-term immersion (3 to 15 minutes) in Corega resulted in minimal changes, maintaining flexural strength and modulus of elasticity above ISO standards. On the other hand, all groups experienced a considerable decrease in mechanical characteristics after an 8-hour soak, especially when using Protefiks and Aktident cleansers. Commercial denture cleansers affect the mechanical properties of resins, with the extent of impact influenced by cleanser composition and immersion duration. Corega demonstrated superior performance in preserving material properties, emphasizing the importance of selecting appropriate cleaning agents for dental prosthetics.

Özet

Bu çalışmanın amacı, üç ticari diş protezi temizleyicisinin farklı daldırma süreleri boyunca oto-polimerize polimetil metakrilat (PMMA) reçinelerinin eğilme mukavemetini ve elastik modülünü etkileyip etkilemediğini değerlendirmekti. Çubuk şeklindeki numuneler (2x2x25 mm) oto-polimerize PMMA'dan üretildi ve eğilme özelliklerini değerlendirmek için üç noktalı eğme testlerine tabi tutuldu. Numuneler, üreticilerin yönergelerine uygun olarak 3 dakika, 15 dakika ve 8 saat süreyle üç diş protezi temizleyicisine (Aktident, Corega ve Protefiks) daldırıldı. Eğilme mukavemeti ve elastik modül, ISO 20795-1:2013 standartlarına göre evrensel bir test makinesi kullanılarak ölçüldü. İstatistiksel analiz, SPSS yazılımı kullanılarak gerçekleştirildi ve önem α = 0,05 olarak ayarlandI. Daldırma, PMMA'nın eğilme özelliklerini önemli ölçüde etkiledi. Corega'da kısa süreli daldırma (3 ila 15 dakika) minimum değişikliklere yol açtı, eğilme mukavemetini ve elastikiyet modülünü ISO standartlarının üzerinde tuttu. Öte yandan, tüm gruplar 8 saatlik bir daldırmadan sonra, özellikle Protefiks ve Aktident temizleyicileri kullanıldığında, mekanik özelliklerde önemli bir azalma yaşadı. Ticari diş protezi temizleyicileri, reçinelerin mekanik özelliklerini etkiler ve etki derecesi temizleyici bileşiminden ve daldırma süresinden etkilenir. Corega, malzeme özelliklerini korumada üstün performans göstererek, diş protezleri için uygun temizlik maddelerinin seçilmesinin önemini vurguladı.
