CBCT Analysis of Root Canal Filling Using Different Obturation Techniques (In Vitro Study)

Amjad Saud Alsharif and Samia Mohamed El Sherief

Introduction: The function of root canal filling is to prevent the reinfection and to hermetic seal the root canal space. Many root canal filling techniques have developed to accomplish three-dimensional obturation of root canal system. The Aim of the study: To evaluate the quality of the root canal filling using three different obturation techniques with CBCT. Materials and methods: Thirty extracted human single rooted teeth were prepared for access cavity and working length determining, cleaning and shaping was done using ProTaper Next rotary system. Teeth randomly divided into three groups (n=10) according to the obturation techniques. The first group received root canal filling by lateral compaction technique. The second group received root canal filling by using single cone technique (ProTaper F3). The third group received root canal filling by using Calamus with gutta-percha cartridges. The resin-based sealer that used is the same for all groups. Results: CBCT cross section evaluated at three levels (apical, middle, coronal). The result showed that with lateral compaction and single cone technique voids present more at the middle and coronal third. With Calamus technique more voids at the coronal part. The comparison of the obturation techniques showed no significant differences between the three groups. Conclusion: from our result we can conclude that all the systems showed minimum voids at the apical part rather than the middle and coronal part. There was no significant difference between obturation techniques. There wasn’t any system showed obturation void-free.
