Comparison of Apical Sealing Ability of Two Root Canal Filling Techniques
Violeta Dogandziyska
Abstract: Success in root canal treatment was founded upon the triad of thorough canal debridement, effective disinfection and obturation of the canal space. Three - dimensional obturation of the canal space to the working length has been depicted as the most critical component of root canal treatment for sealing and isolating the canal space from irritants that remain after shaping and cleaning, and for eliminating leakage from the periradicular tissues or oral cavity into the filled canal space. The aim of our in vitro study was to evaluate the sealing quality of the core - carrier system GuttaCore and compare it with central cone technique with tapered gutta - percha cones regarding apical leakage.24 human single rooted teeth were used for the study. Root canal preparation was done using ProTaper Universal rotary system up to F3. The teeth were randomly assigned into 2 groups, depending on the root canal filling technique. The specimens were immersed in 2% methylene blue dye and the linear dye leakage at the apical third was measured in mm. Statistical analysis showed that Guttacore group had significantly less leakage in apical third than the central cone technique. Under the conditions of this study, it could be concluded that obturator techniques showed better sealing results as the central cone technique in the apical third of root canals.
