Color Stability of NeoMTA Plus and MTA Plus when Mixed with Anti-washout Gel or Distilled Water

Objective: This study aims to evaluate the effect of the special anti-washout gel mixing agent on the color stability of mineral trioxide aggregate (MTA) Plus and NeoMTA Plus in contact with distilled water, ethylenediaminetetraacetic acid (EDTA) and sodium hypochlorite (NaOCl). Materials and Methods: One set of three specimens was mixed using the antiwashout gel and the other set of three specimens was mixed using distilled water. Then, one specimen from each group was immersed in distilled water, 5% NaOCl or EDTA solutions for 24 hours. The color change of each specimen was assessed using spectrophotometer. The data were evaluated statistically with two-way ANOVA and post-hoc Tukey tests. Results: It was found that there was no statistically significant differences among the color changes of the MTA Plus and NeoMTA Plus mixed with either distilled water or gel when immersed in distilled water and EDTA (p>0.05). Immersion to NaOCl resulted in the highest discoloration in all materials compared to their immersion to distilled water and EDTA. MTA Plus mixed with distilled water showed significantly greatest discoloration after contact with NaOCl (p

Çözünmeye Dirençli Jel veya Distile Suyla Hazırlanan NeoMTA Plus ve MTA Plus Materyallerinin Renk Stabilitelerinin Değerlendirilmesi

Amaç: Bu çalışma, özel çözünme direnci sağlayan jel karıştırma ajanlarının mineral trioksit agregat (MTA) Plus ve NeoMTA Plusın renk stabilitelerine etkisini materyallerin distile su, etilendiamintetraasetik asit (EDTA) ve sodium hipoklorit (NaOCl) temasları sonrası değerlendirmeyi amaçlamaktadır. Gereç ve Yöntemler: Her iki materyalden üç numune içeren bir set çözünmeye dirençli jel kullanılarak, diğer set ise distile su kullanılarak hazırlandı. Daha sonra, her setten birer numune 24 saat boyunca distile su, %5’lik NaOCl veya EDTA solüsyonları içerisinde tutuldu. Her materyalde meydana gelen renk değişikliği pektrofotometre kullanılarak değerlendirildi. Veriler iki-yönlü ANOVA ve post-hoc Tukey testleri kullanılarak istatistiksel olarak değerlendirildi. Bulgular: MTA Plus ve NeoMTA Plus materyalleri jelle veya distile suyla karıştırılıp hazırlandıklarında distile su ve EDTA ile temasları sonucu meydana gelen renk değişiklikleri arasında istatistiksel olarak anlamlı fark olmadığı bulundu (p>0,05). NaOCl da bekletilen örneklerin tamamında distile su ve EDTA içinde bekletilen örneklere kıyasla yüksek renklenme görüldü. Distile su ile hazırlanan MTA Plus, NaOCl ile temas sonrası en yüksek renk değişimini gösterdi (p
