FARKLI KONSANTRASYONLARDAKİ SODYUM HİPOKLORİT SOLÜSYONLARININ ENDODONTİK TEDAVİLİ DİŞLERİN KIRILMA DİRENCİNE ETKİSİ

Amaç: Bu çalışmanın amacı, iki farklı konsantrasyondaki sodyum hipoklorit yıkama solüsyonlarının endodontik tedavili dişlerin kırılma direncine etkisinin karşılaştırılmasıdır. Gereç ve Yöntem: 40 adet çekilmiş insan alt kesici dişleri toplanarak distile su içerisinde çalışma yapılana kadar bekletildi. 10 adet prepare edilmemiş diş rastgele seçilerek kontrol grubu oluşturuldu (Grup 1). Kalan örnekler rastgele 3 deney grubuna ayrıldı. Örnekler farklı yıkama prosedürleri uygulanarak ProTaper eğe sistemi ile F3 numaralı eğeye kadar prepare edildi: Grup 2: serum fizyolojik, Grup 3: %1’lik NaOCl ve Grup 4: %5,25’lik NaOCl. Kanal dolumu yapıldıktan sonra dişlerin kırılma dirençleri Universal test cihazı kullanılarak test edildi. Bulgular: Kontrol grubu (Grup 1) ile deney grupları arasında istatistiksel olarak anlamlı fark bulundu (Grup 2, 3, 4) (P<0,05). Kontrol grubundaki örneklerin diğer deney gruplarındakine göre daha yüksek kırılma direncine sahip olduğu saptandı. Fakat diğer deney grupları (Grup 1, 2, 3) arasında istatistiksel olarak anlamlı bir farka rastlanılmadı (P>0,05). Sonuç: Kök kanal preparasyonu diş dokusunu zayıflatan bir işlemdir. Sodyum hipokloritin konsantrasyonu vertikal kök kırıklarının oluşumda etkili bir faktör değildir.

EFFECT OF SODIUM HYPOCHLORIDE SOLUTIONS IN DIFFERENT CONCENTRATIONS ON THE FRACTURE RESISTANCE OF ENDODONTICALLY TREATED TEETH

Aim: The aim of this study is to compare the effect of two different concentrations of sodium hypochlorite solution on the fracture resistance of endodontically treated teeth. Materials and Method: 40 extracted human lower incisors were collected and kept in distilled water until the study was performed. The control group was formed by randomly selecting 10 unprepared teeth (Group 1). The remaining samples were randomly divided into 3 experimental groups. Samples were prepared with ProTaper file system by using different irrigation procedures up to the file numbered F3: Group 2: saline, Group 3: 1% NaOCl and Group 4: 5.25% NaOCl. After filling the canal, the fracture resistance of the teeth was tested using a Universal test machine. Results: A statistically significant difference was found between the control group (Group 1) and the experimental groups (Group 2, 3, 4) (P<0.05). It was determined that the samples in the control group had higher fracture resistance than the other experimental groups. However, no statistically significant difference was found between the other experimental groups (Group 1, 2, 3) (P>0.05).Conclusion: Root canal preparation is a procedure that weakens the dental tissue. The concentration of sodium hypochlorite is not an effective factor in the formation of vertical root fractures.
