Effect Of Different Single File Systems On The Dentin Thickness In The Danger Zone Of Mandibular First Molars
Abstract
Background: To compare the dentin thickness in the danger zone of mandibular molars after preparation with one rotating (XP-endo Shaper) and two reciprocating (One Reci and Reciproc Blue) single file systems using a cone beam computed tomography (CBCT).
Materials and Methods: Thirty-six mesial roots of mandibular first molars having two independent canals were selected. After initial CBCT scans were provided, teeth were assigned into 3 groups related to the single file used: XP-Endo Shaper (XPS), One Reci (OR) and Reciproc Blue (RB). The roots were scanned again after preparation with respective single file systems. The minimum dentine thickness in the danger zone, at 4, 5, 6 and 7 mm below the furcation level, were measured in CBCT scans. Initial and final measurements were used to calculate the removed dentin thickness in the danger zone. Data was analyzed using Repeated-measures ANOVA (p=0.05).
Results : No significant differences were found related with remaining and removed dentin thickness among single file systems at any level from the furcation (p>0.05).
Conclusions: The evaluated single file systems showed similar cutting efficiency in the danger zone of mandibular molars.

Farklı Tek Eğe Sistemlerinin Alt Çene Birinci Büyük Azı Dişlerinin Tehlike Alanındaki Dentin Kalınlığına Etkisi
Abstract
Amaç: Alt çene büyük azı dişlerin tehlike alanındaki dentin kalınlığını, bir rotasyonel (XP-Endo Shaper)ve iki resiprokal (One Reci ve Reciproc Blue) hareketle çalışan tek eğe sistemi ile şekillendirme sonrası konik ışınlı bilgisayarlı tomografi (KIBT) kullanarak karşılaştırmaktır.
Gereç ve Yöntemler: Otuz altı adet alt çene birinci büyük azının iki ayrı kök kanalına sahip mezial kökleri seçildi. Başlangıç KIBT taramaları yapıldıktan sonra, dişler kullanılacak tek eğe sistemine göre 3 gruba ayrıldı: XP-Endo Shaper (XPS), One Reci (OR) ve Reciproc Blue (RB). Kökler ilgili tek eğe sistemi ile şekillendirildikten sonra tekrar KIBT ile tarandı. Furkasyon seviyesinin 4,5, 6 ve 7 mm altından tehlike alanındaki en az dentin kalınlığı KIBT taramalarında ölçüldü. Başlangıç ve final ölçümler tehlike alanındaki uzaklaştırılan dentin kalınlığını hesaplamak için kullanıldı. Veriler tekrarlayan ölçümlerde ANOVA kullanılarak analiz edildi (p<0.05).
Bulgular: Tek eğe sistemleri arasında furkasyondan itibaren hiçbir seviyede kalan ve uzaklaştırılan dentin miktarı açısından fark bulunmadı (p>0.05).
Sonuçlar: Değerlendirilen tek seğe sistmeleri alt çene büyük azı dişlerin tehlike alanında benzer kesme etkinliği gösterdi.
