Abstract
Amac: Bu calismanın amaci, farklı sodyum perborat (SP) tipleri ile intrakoronal agartma tedavisinden sonra siman bariyerin baglanma dayaniminın belirlenmesidir. Gerec ve Yontem: Seksen adet gekilmiş alt santral kesici dis kullanildi. Kok kanallannin dolgu pati ve guta perka ile doldurulmalası takiben Cizerlerine labial mine sement birlesiminin 2 mm apikalinde 2 mm kalinlıginda cinkofosfat siman bariyeri yerlestirildi. Dişler rasgele on disten olusan sekiz gruba bölündu. Agartma ajanları dişlerin pulpa odalanna asagidaki gibi 3-7 gun icin yerleştirildi ve Cavit ile kapatildi. Grup 1: SP monohidrat (MH) su, Grup 2: SP trihidrat (TRH) su, Grup 3: SP tetrahidrat (TH) su, Grup 4: SP-MH hidrojen peroksit(HP), Grup 5: SP-TRH HP, Grup 6: SP-TH HP. Omekler siman kaidenin en Cist kismindan baslanilarak apikal yonde 2 mm kalinliginda olacak sekilde dusuk hizli bir elmas separe araciligi ile su sogutmasi altmda hazirlandi. Elde edilen kok parcalan iizerinde push-out test teknigi kullanilarak siman bariyerin kokkanal dentini ile olan baglanma dayammlari olguldu. Sonuglar, One-way ANOVA ve Duncan testleri yapilarak istatistiksel olarak analiz edildi. Bulgular: Monohidratin hem su hem de hidrojen peroksit gruplarmin ve TRH ve TH'in hidrojen peroksit gruplannin baglanma dayanimdaki azalma grup 7'ye gore istatistiksel olarak onemli bulundu (p0.05). Trihidrat ve tetrahidratin su gruplannin baglanma dayanimmdaki azalma ise istatistiksel olarak onemli degildi (p0.05). Sonuc: Bu calismanın sonuçlarına göre, tüm agartma ajanları siman bariyerin baglanma dayanıminda azalmalara neden oldugu belirlendi.
Objective: The aim of this study was to evaluate bond strength of cement barrier after intracoronal bleaching treatment with different types of sodium perborate (SP). Material and Method: Eighty extracted human mandibular central incisors with intact crowns were used. Following obturation with gutta-percha and a root canal sealer, the coronal aspects of the root canal fillings were covered with a 2 mm thick protective base placed to a level 2 mm apical to the labial cemento-enamel junction (CEJ). The teeth were randomly divided into eight groups including ten teeth each. Bleaching agents were were placed in the pulp chamber of the teeth and sealed with Cavit for 3-7 days as follows; Group 1 :SP monohydrate (MH) water, Group 2: SP trihydrate (TRH) water, Group 3: SP tetrahydrate (TH) water, Group 4: SP-MH hydrogen peroxide (HP), Group 5: SP-TRH HP, Gro¬up 6: SP-TH HP. The specimens were prepared at 2 mm thick from top of cement barier to apex using a diamond saw in a low speed under water cooling. The bond strength of cement barrier to root canal dentine on obtained root specimens was measured using push-out test technique. The results were then statistically analyzed by One-way ANOVA and Duncan tests. Results: Monohydrate groups mixed with hydrogen peroxide or water and hydrogen peroxide groups of TRH and TH showed statistically significant decrease the bond strength when compared the group 7 (p<0.05). There was not a significant decrease the bond strength after treatment with water groups of TRH and TH (p>0.05). Conclusion: The data obtained from this study demostrates that all bleaching agents have decrease on bond strength of cement.
