The quality of different preparation and root canal filling techniques in curved root canals [E?imli kök kanallarinda kullanilan farkli preparasyon ve kök kanali dolgu tekniklerinin kalitesi]

Abstract

Objectives: The aim of this study was to evaluate the quality of different root canal filling techniques that lateral compaction (LC) and thermoplasticized injectable (TPE) gutta percha in curved root canals which were prepared Revo-S or self-adjusting file (SAF) using digital radiographs. Materials and Methods: Fourty extracted mandibular molar of mesial canals of teeth which have curved root canals were prepared using SAF or Revo-S instruments. After determination of root canal curvatures in two directions, the canals were divided two subgroups (n=20, p>0.05). Both mesiobuccal and mesiolingual canals were shaped and filled with AH Plus and either LC technique or TPE gutta percha obturation technique. The specimens were stored for 1 week at 37 °C and 100% humidity to allow the complete setting of the sealer. Postoperative digital radiographs were taken to evaluate the quality of root canal fillings. Data were analysed using Mann-Whitney U tests. Result: In terms of the preparation techniques, no significant differences were found between the root canal filling techniques (p=0.051, p=0.127). Conclusion: Under the conditions of the present study, neither preparation nor obturation techniques did not affect the quality of root canal filling in curved root canals.
