Abstract

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.

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

Abstract

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.
