Abstract

Aim: The aim of this study was to evaluate the effect of various pulpotomy materials on the fracture resistance of pulpotomized primary second molars.
Materials and Methods: Hundred extracted primary second molars were randomly divided into five groups as follows: Control group (had no treatment), Zinc oxide-eugenol group (pulpotomized with zinc oxide eugenol), ProRoot MTA group (pulpotomized with ProRoot MTA), RetroMTA group (pulpotomized with RetroMTA), and Biodentine group (pulpotomized with Biodentine). The pulpotomized teeth were restored with compomer resin. All samples were then subjected to fracture resistance test using a universal testing machine. Data were analyzed using one-way ANOVA followed by post hoc Tukey’s test. The level of significance was accepted at p<0.05.
Results: Control group had the highest fracture resistance value (1191.57 ± 121.09 N) and Zinc oxide-eugenol group had the lowest fracture resistance value (510.87±135.00). There was statistically significant difference between fracture resistances of the groups (p<0.001). The difference between Zinc oxide-eugenol group and RetroMTA group; Zinc oxide-eugenol group and ProRoot MTA group; ProRoot MTA group and Biodentine group was not statistically significant (p>0.05). However, Biodentine group showed significantly higher fracture resistance as compared to Zinc oxide-eugenol group and RetroMTA group (p<0.05).
Conclusions: The fracture resistance of primary second molars pulpotomized with ProRoot MTA and Biodentine was higher compared to the teeth pulpotomized with zinc oxide eugenol and RetroMTA.
Key words: pulpotomy, tooth deciduous, fracture resistance, compomers
ÇEŞİTLİ MATERYALLERLE PULPOTOMİ YAPILMIŞ İKİNCİ SÜT AZI DİŞLERİNİN KIRILMA DAYANIMLARI: İN-VİTRO BİR ÇALIŞMA
Amaç: Bu çalışmanın amacı, farklı tipteki pulpotomi materyallerinin pulpotomi yapılmış süt azı dişlerinin kırılma dayanımları üzerindeki etkisini araştırmaktır.
Gereç ve Yöntem: Yüz adet çekilmiş süt ikinci azı dişi rastgele beş gruba ayrılmıştır: Kontrol grubu (herhangi bir tedavi yapılmamıştır), Çinko oksit öjenol grubu (çinko oksit ojenol ile pulpotomi yapılan), ProRoot MTA grubu (ProRoot MTA ile pulpotomi yapılan), RetroMTA grubu (RetroMTA ile pulpotomi yapılan), Biodentin grubu (Biodentin ile pulpotomi yapılan). Pulpotomi yapılan dişler, kompomer ile restore edilmiştir. Tüm örnekler universal test cihazı kullanılarak kırılma dayanımı testine tabi tutulmuştur. Veriler tek yönlü ANOVA ve post hoc Tukey testi kullanılarak analiz edilmiştir. Anlamlılık düzeyi p <0,05 olarak kabul edilmiştir.
Bulgular: Grupların kırılma dayanımları arasında istatistiksel olarak anlamlı fark bulunmuştur (p<0,001). Kırılma dayanımı kontrol grubunda, en yüksek bulunurken (1191,57±121,09 N), Çinko oksit öjenol grubunda en düşük bulunmuştur (510,87±135.00). Çinko oksit öjenol grubu ve RetroMTA grubu; Çinko oksit öjenol grubu ve ProRoot MTA grubu ; ProRoot MTA grubu ve Biodentin grubu arasındaki fark istatistiksel olarak anlamlı bulunmamıştır (p> 0,05). Bununla birlikte, Biodentine grubu, Çinko oksit öjenol grubu ve RetroMTA grubu ile karşılaştırıldığında kırılmaya karşı daha yüksek dayanım göstermiştir (p <0,05)
Sonuç: ProRoot MTA ve Biodentin ile pulpotomi tedavisi uygulanmış ikinci süt azı dişlerinin kırılma dayanımları, çinko oksit öjenol ve RetroMTA ile pulpotomize edilmiş dişlerden daha yüksektir.
