Abstract

Objectives: Conservative endodontic cavity (CEC) design has recentlydeveloped to maintain the stability of tooth and provided an alternative totraditional endodontic cavity (TEC) design. The purpose of this study was toassess the influence of cavity design on calcium hydroxide (Ca(OH)2)removal from artificial grooves in the coronal and apical parts of root canals.Materials and Methods: Fourty extracted human mandibular premolars withsingle canals were randomly assigned to CEC or TEC groups (n=20).Following cavity preparation, the root canals were instrumented withProTaper Universal rotary system up to F3 file and then, each tooth wassectioned longitudinally. Two standardized grooves were prepared in thecoronal and apical parts of 1 root half. Ca(OH)2 was placed into the groovesand the root halves reassembled. After 1 week, each root canal was enlargedwith a #40 H-file. Irrigation was performed with the sonic activation of 5 mL2.5% sodium hypochlorite and 5 mL 17% ethylenediaminetetraacetic acidsolutions using the medium size tip (25/04) of EndoActivator System atmedium speed for 30 seconds between each 2.5 mL irrigant. The remainingCa(OH)2 in the grooves was evaluated using a stereomicroscope with x25magnification and the images were scored using a 4-scoring scale by 2examiners. Data were analyzed using the Mann-Whitney U and Wilcoxontests.Results: Ca(OH)2 remnants were found in both groups. There was nosignificant difference between the CEC and TEC groups in terms of Ca(OH)2removal efficacy (p>0.05). The grooves in the coronal and apical parts of theroots presented similar amount of Ca(OH)2 remnantsin both groups (p>0.05).Conclusions: Based on the present findings, the cavity design had no effecton the removal of Ca(OH)2 from root canal irregularities.

Özet

Giriş: Konservatif endodontik kavite (KEK) tasarımı son zamanlarda dişlerin mekanik stabilitesini korumak için geliştirilmiştir ve geleneksel endodontik kavite (GEK) tasarımına bir alternatif olarak yerini almıştır. Bu çalışmanın amacı, kavite tasarımının, kalsiyum hidroksitin (Ca(OH)2) kök kanallarının koronal ve apikal kısımlarında hazırlanan yapay oluklardan uzaklaştırılmasına olan etkisini araştırmaktır. Gereç ve Yöntemler: Kırk adet çekilmiş tek kanallı insan alt küçük azı dişleri, rastgele KEK ve GEK gruplarına ayrıldı (n=20). Kaviteler hazırlandıktan sonra, kök kanalları ProTaper Universal döner eğe sistemi ile F3 eğesine kadar genişletildi ve her diş uzunlamasına kesildi. Kök parçalarından birinin koronal ve apikal kısımlarında 2 adet standart oluk hazırlandı. Ca(OH)2 olukların içine yerleştirildi ve kök yarıları yeniden birleştirildi. Bir hafta sonra, her bir kök #40 H-tipi el eğesi ile genişletildi. İrrigasyon 5 mL %2,5'luk sodyum hipoklorit ve 5 mL %17'lik etilendiamintetraasetik asit solusyonlarının, EndoActivator sisteminin orta hızda, orta boy uç (25/04) ile her 2,5 mL irrigant arasında 30 saniye süreyle kullanılmasıyla gerçekleştirilen sonik aktivasyonu ile yapıldı. Oluklarda kalan Ca (OH)2 miktarı bir stereomikroskop kullanılarak x25 büyütme ile değerlendirildi ve görüntüler 2 araştırmacı tarafından 4-skorlu skala kullanılarak skorlandı. Veriler Mann-Whitney U ve Wilcoxon testleri kullanılarak analiz edildi. Bulgular: Her iki grupta da Ca(OH)2 kalıntıları bulundu. KEK ve GEK grupları arasında Ca(OH)2'in uzaklaştırılma etkinliği açısından anlamlı fark yoktu (p>0,05). Köklerin koronal ve apikal kısımlarındaki oluklar her iki grupta da benzer miktarda Ca(OH)2 kalıntıları gösterdi (p>0,05). Sonuçlar: Çalışmanın bulgularına göre, kavite tasarımının Ca(OH)2'in kök kanal düzensizliklerinden uzaklaştırılması üzerinde etkisi yoktu.
