Abstract

Background
This in vitro study aimed to evaluate the persistence of calcium hydroxide (CH) associated with different vehicles on the artificial cavities after removing with sonic activation or conventional needle irrigation (CNI). Methods Seventy-two extracted single-rooted teeth were instrumented with ProTaper Universal rotary system up to F4. The roots were split longitudinally, and standardized cavities were prepared. The roots were assigned into 3 groups (n=24), according to vehicles used; distilled water, glycerin, and propylene glycol. In each group, cavities were filled with CH mixed with the respective vehicle. After reassembly, the removal of CH dressing was performed with either sonic activation (with EDDY) or CNI (n=12).The remnants of CH was assessed under a microscope with x40 magnification. A four-grade scoring system was used to evaluate. Kruskal-Wallis and Mann-Whitney U-tests were used to compare the data. (p <0.05). ResultsThere was a significant difference among groups (p<0.05). Complete removal of CH was found in the distilled water and propylene glycol groups when EDDY was used (p<0.05).EDDY was significantly more effective than CNI in the removal of CH mixed with distilled water and propylene glycol (p<.05).Whereas no significant difference was found between EDDY and CNI in the glycerin group (p>0.05).The lowest CH remnants were found in the distilled water group when CNI was used (p<0.05).Conclusion The vehicle associated with CH and irrigation activation is important for its retrieval. EDDY provided the complete removal of CH when mixed with distilled water or propylene glycol.

Taşıyıcı tipi sonik aktivasyon kullanılarak uzaklaştırılan kalsiyum hidroksitin kök kanal duvarlarından uzaklaştırılmadan kalmasını etkiler mi?

Abstract

Amaç
Bu çalışma farklı taşıyıcılarla karıştırılan kalsiyum hidroksitin (KH) yapay olarak oluşturulmuş kavitelerden sonik aktivasyon veya geleneksel iğne irrigasyonu (Gİİ) kullanılarak uzaklaştırılmasından sonra kalan miktarını karşılaştırmayı amaçlamaktadır.
Gereç ve Yöntemler
72 adet çekilmiş düz-tek köklü alt çene birinci küçük azı dişleri ProTaper Universal döner eğe sistemi ile F4 eğesine kadar genişletildi. Dişler uzunlamasına kesilerek standart kaviteler açıldı. Kullanılan taşıyıcı tipine göre kökler 3 gruba ayrıldı (n=24); distile su, gliserin ve propilen glikol. Her bir grupta, kaviteler bu taşıyıcılardan biriyle karıştırılan kalsiyum hidroksitle dolduruldu. Kök parçalarının tekrar birleştirilmesinden sonra kalsiyum hidroksitin uzaklaştırılması ya sonik aktivasyon (EDDY ile) ya da Gİİ ile yapıldı (n=12). Kalan KH miktarı bir mikroskop kullanılarak x40 büyütme ile değerlendirildi. Değerlendirme için 4-skorlu skala kullanıldı. Kruskal-Wallis, Mann-Whitney U testleri verileri karşılaştırmak için kullanıldı. Bulgular
Gruplar arasında anlamlı fark bulundu (p<0.05). Distile su ve propilen glikol ile karıştırılan KH’in EDDY ile tamamen uzaklaştırıldığı bulundu (p<0.05). Distile su ve propilen glikol ile karıştırılan KH’i uzaklaştırmada EDDY, Gİİ’den daha etkili bulundu (p<0.05). Fakat gliserin ile karıştırılan KH’i uzaklaştırmada EDDY ve Gİİ arasında fark bulunmadı (p>0.05). Gİİ kullanıldığında kalan KH miktarı en az distile su grubunda bulundu (p<0.05).
Sonuç
KH’in uzaklaştırılmasında kullanılan taşıyıcı tipi ve yıkama solusyonunun aktivasyonu önemlidir. EDDY distile su veya propilen glikol ile karıştırılan KH’in tamamen uzaklaştırılmasını sağlanmıştır.
