Farklı adeziv sistemlerin kalsiyum silikat esaslı pulpa kaplama materyallerine makaslama bağlanma dayanımının değerlendirilmesi

Amaç: Bu çalışma, kalsiyum silikat ve kalsiyum hidroksit esaslı pulpa kaplama materyallerine farklı adeziv sistemlerin makaslama bağlanma dayanımı (SBS) değerlerini incelemeyi amaçlamıştır. Yöntemler: 120 adet akrilik bloğun ortasına silindir şeklinde kaviteler (2x5 mm) hazırlanmıştır. Kavitelere üç adet pulpa kaplama materyali (Biodentine, TheraCal LC, Kerr Life) yerleştirildi. Her bir pulpa kaplama materyali (n=10) için Single Bond 2 (SB2), Clearfil SE Bond (CSB), Clearfil Universal Bond (CUB), Tokuyama Self-cured Universal Bond (TUB) uygulandı. Kompozit rezin silindirler hazırlandıktan sonra makaslama testleri yapılmıştır. Veriler ve kırılma başarısızlıkları sırasıyla iki yönlü ANOVA, Tamhane’s T2 (p≤0.05) ve stereomikroskop kullanılarak analiz edildi. Bulgular: TheraCal LC’de, en yüksek bağlanma değerleri görülmüş olup, tüm adezivler için pulpa kaplama materyalleri arasında istatistiksel olarak anlamlı bir fark bulunmuştur (p≤0.05). En düşük sonuçlar Life+TUB (0,79±0,14), en yüksek sonuçlar ise TheraCal LC+CSB (8,55±1.73) grubuna aittir. Tüm adeziv sistemler için Biodentine grubu TheraCal LC gruplarına göre daha düşük sonuçlar gösterirken, Life ile karşılaştırıldığında SB2 ve TUB arasında istatistiksel olarak anlamlı bir fark izlenmiştir. Sonuç: Farklı jenerasyon adeziv sistemlerde yüksek bağlanma dayanımı değerine sahip olan TheraCal LC, kompozit restorasyonlarda pulpa kapaklama ajanı olarak tercih edilebilir.

Evaluation of the shear bond strength of various adhesive systems to calcium silicate based pulp capping materials

Aim: This study aimed to evaluate the shear bond strength (SBS) values of different adhesive systems to calcium silicate and calcium hydroxide-based pulp capping materials. Methods: Cylinder-shaped cavities (2x5 mm) were prepared in the middle of 120 acrylic blocks. Three pulp capping materials (Biodentine, TheraCal LC, Kerr Life) were placed into the cavities. Single Bond 2 (SB2), Clearfil SE Bond (CSB), Clearfil Universal Bond (CUB), Tokuyama Self-cured Universal Bond (TUB) were applied for each pulp capping material (n=10). After composite resin cylinders were prepared, SBS tests were carried out. Data and failure modes were analyzed using two-way ANOVA, Tamhane’s T2 (p≤0.05), and stereomicroscope, respectively. Results: TheraCal LC showed the highest SBS values, and there was a statistically significant difference amongst pulp capping materials for all adhesives (p≤0.05). The lowest results were found in the Life+TUB (0.79±0.14), and the highest was TheraCal LC+CSB (8.55±1.73). In Biodentine, all adhesive systems showed lower results than TheraCal LC groups, whereas there was a statistically significant difference between SB2 and TUB compared to the Life. Conclusion: TheraCal LC, which has the highest bond strength value in different generation adhesive systems, can be preferred as a pulp capping agent for composite restorations.
