Abstract

Background: One of the significant stages during endodontic procedures is determining the correct working length (WL). This study aimed to evaluate the accuracy of four electronic apex locators (EALs) (Root ZX mini, Raypex 6, Propex Pixi, and E-Pex Pro) and cone-beam computed tomography (CBCT) and radiographic measurement in determining the actual WL (A-WL). Methods: Thirty extracted single-root mandibular premolars were selected and flattened at the crown. The WL was determined by advancing the #15 K file until its tip was visible from the apical, and the A-WL was established by subtracting 0.5 mm from this length. The WL was also determined using periapical radiography, four EALs, and CBCT. The differences in all measurements were compared with the A-WL. The data were statistically analyzed using one-way analysis of variance (Welch) and Tamhane’s test. The significance level was set at p < 0.05. Results: Compared with other measurement methods, CBCT gave shorter values than the A-WL, and this finding was statistically significant compared with those of the PR and Propex Pixi groups (p = 0.009) (p = 0.024). No significant difference was observed between the other groups (p > 0.05) except the CBCT group (p < 0.05). Conclusions: Root ZX mini and Raypex 6 made measurements close to the A-WL.

Abstract

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars. Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals. Results: No differences were found in canal transportation measures and instrumentation time between the two groups (p>0.05). The EndoArt group removed more dentin compared to K-file in all sides of the root curvature. The statistical differences were significant for coronal and middle third of the root (p<0.05). Conclusions: Under the conditions of this study, rotary EndoArt Ni-Ti Gold Pedo Kit provided more conical canals than K-files in primary teeth.

Abstract

Objectives: This study compared the amount of apically extruded debris and irrigant using VDW.ROTATE instruments with different kinematics (continuous rotation and reciprocation motion) and the ProTaper Gold system. Methods: Sixty extracted mandibular premolar teeth were selected. The teeth were prepared for the agar gel model. The roots were randomly divided into three groups (n=20). In two groups, the root canals were instrumented using the following movement kinematics: VDW.ROTATE reciprocation motion and continuous rotation. In the other group, root canals were prepared with ProTaper Gold. Apically extruded debris and irrigant during instrumentation were collected into preweighed Eppendorf tubes and were assessed with an electronic balance. All procedures were performed in a 35oC hot water bath. The data were analyzed using the Shapiro–Wilk and Kruskal–Wallis tests at a 5% significance level. Results: ROTATE-Reciprocation extruded the least amount of debris, but this finding was not significant when compared with the amount of debris and irrigant extruded by the ProTaper Gold and ROTATE-Rotation (p>.05). Conclusion: All instrumentation kinematics were associated with apical debris and irrigant extrusion. Movement kinematics did not affect the amount of apically extruded debris and irrigants when using VDW.ROTATE instruments.
