Amaç: Bu çalışmanın amacı, beyazlatma tedavi protokolünden sonra beş farklı tek-renk rezin kompozitinin yüzey pürüzlülüğünü ve mikro sertliğini in-vitro olarak değerlendirmekti.
Gereç ve Yöntem: Her tek-renk rezin kompozit materyalden, yüzey pürüzlülüğü ve mikro sertlik testi için onar örnek olmak üzere (Filtek Universal [FU], Vittra Unique [VU], Omnichroma [O], Essentia Universal [EU], Charisma Diamond One [CDO]) toplam elli rezin kompozit örneği hazırlandı (n=10). Başlangıç ölçümlerinden sonra, örnek yüzeylerine üç kez ofis-tipi ağartma jeli uygulandı ve her uygulama süresi 15 dakikaydı. Ağartma protokolünden sonra, ölçümler tekrarlandı ve değerler ANOVA ve post hoc Bonferroni testleri kullanılarak istatistiksel olarak analiz edildi (p<0.05).
Bulgular: EU grubunda (0.012±0.022 Ra) pürüzlülükteki artış miktarı diğer gruplardan anlamlı derecede daha yüksekti (p<0.05). VU grubunda (-15.84±9.53 MPa) mikro sertlikteki azalma miktarı diğer gruplardan anlamlı derecede daha yüksekti (p<0.05). Diğer gruplar arasında istatistiksel olarak anlamlı bir fark yoktu (p>0.05).
Sonuç: Ağartma sonrası pürüzlülükte en fazla artış gösteren materyal EU oldu. Ofis-tipi ağartma ajanının tüm materyallerde mikro sertlikte azalmaya neden olduğu gözlendi. Klinik uygulamalarda ofis-tipi ağartma ajanı kullanılması düşünülüyorsa, hastanın mevcut restorasyonlarında meydana gelebilecek olumsuz etkiler göz önünde bulundurularak planlama yapılması faydalı olabilir.

Evaluation of The Effect of In-Office Bleaching Agent on Mechanical Properties of Different Single-Shade Resin Composites: An In-Vitro Study

Öz

Aim: This study aimed to evaluate the surface roughness and micro-hardness of five different single-shade resin composites in vitro after a bleaching treatment protocol.
Material and methods: A total of fifty resin composite specimens were prepared from each single-shade resin composite (Filtek Universal [FU], Vittra Unique [VU], Omnichroma [O], Essentia Universal [EU], Charisma Diamond One [CDO]). Ten specimens were prepared from each material, for surface roughness and micro-hardness testing (n=10). After the first measurements, in-office bleaching gel was applied to the specimen surfaces three times, and each application took 15 minutes. After the bleaching protocol, the measurements were repeated, and the values were statistically analyzed using ANOVA and post hoc Bonferroni tests. Significance was evaluated at a p<0.05 level.
Results: After bleaching, the increase in roughness in the EU group (0.012±0.022 Ra) was significantly higher than in the other groups (p<0.05). The decrease in micro-hardness in the VU group (-15.84±9.53 MPa) was significantly higher than in the other groups (p<0.05). There was no statistically significant difference between the other groups (p>0.05).
Conclusion: The material that showed the highest increase in roughness after bleaching was EU. It was observed that the office-type bleaching agent caused a decrease in micro-hardness in all materials. If the use of office-type bleaching agents is considered in clinical practice, it may be useful to plan by taking into account the possible negative effects on the patient's existing restorations.
