Lisans Öğrencileri Tarafından Manuel Aletlere Karşı Döner Aletler Kullanılarak Gerçekleştirilen Kök Kanal Tedavisinin Teknik Kalitesi: Bir Retrospektif Çalışma

Background: The technical quality of root canal treatment (RCT) may impact on the outcome. education received during undergraduate school be linked to provided in general dental practice.
 Objective: To compare RCT where rotary or manual step-back preparatory technique was employed an clinic Turkey. Additionally, present study aimed radiographically commonly seen complications both instrumentation systems.
 Materials and Methods: Dental records 270 patients who undertaken by students were investigated retrospective chart review. 565 canals belonging randomized into two groups [(rotary, n=280, hand instruments, n=285)]. Root obturation evaluated basis length being >2mm from radiographic apex, with uniform radiodensity good adaptation walls. Inadequate included cases containing procedural errors such as perforation, ledge, transportation, instrument separation. Descriptive statistics used define categorical variables (n, %) level significance set at 0.05. 
 Results: performed classified 'adequate' 75% 53.7% cases, respectively for groups, (p < 0.05). highest molars. Occurrence differed significantly between 6.4% group 12.3% = 0.017). However, occurrence ledge formation higher than that 0.007). Conclusion: In view our findings, using systems is also has fewer instrumentation.
