Abstract
Background: Root canal preparation procedure must preserve the canal’s original anatomy by respecting its initial curvature and creating a continuously tapering funnel. 1The shaping of curved canals remains a major challenge for clinicians, and is one of the most important steps of endodontic therapy.The two single-file systems used in our study are WaveOne and Reciproc in reciprocal motion. The aim of the study was to compare the effect of establishing glide path on the centering ability and preparation time of two different Nickel-Titanium single file systems in mesial roots of mandibular first molars. Methods: Eighty extracted mandibular molars with curvatures of 20-35 degrees and were divided into four groups (n=15); WaveOne+glide path; WaveOne; Reciproc+glide path and Reciproc. Non-patent canals were excluded and only one canal in each tooth was instrumented. A manual glide path was established in first and third groups with #10, 15 hand K-files. Preparation was performed with reciprocating in-and-out motion, with a 3-4 mm amplitude and slight apical pressure. Initial and final photographs were taken to analyze the amount of dentin removed in the instrumented canals. The centering ability of the rotary instruments was evaluated using the computer program Corel draw X6 software. Results: No statistically significant differences were found with regards to the centering ability between the four groups or amongst the ay three different locations coronal, middle and apical thirds of the root canals. Conclusion: Within the limitations of the study, it can be concluded that a manual glide path increased the total time involved in preparation of curved canals with WaveOne and Reciproc instruments. A glide path had no influence on the centering ability of these two single-file systems.
