Farklı tek eğe sistemlerinin alt çene birinci büyük azı dişlerinin tehlike alanındaki dentin kalınlığına etkisi

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