Abstract

Many root canal preparation techniques and instruments produce apically extruded materials to a certain extent depending on the preparation system adopted. The extrusion of debris from the apical foramen during chemomechanical preparation may cause postoperative pain and failure of endodontic treatment. Objective: This study evaluates the differences in the apical extrusion of debris and calcium hydroxide (CH) during endodontic instrumentation by using Reciproc Blue (RB), WaveOne Gold (WOG), and F6 Skytaper (F6). Methods: Six experimental study groups (n = 13) were established. The root canal procedures for all groups were prepared with different methods: Group I: One Shape (OS) instrumentation, CH filling for 21 days, removal of CH using RB; Group II: OS instrumentation, CH filling for 21 days, removal of CH using WOG; Group III: OS, CaOH filling for 21 days, removal of CH using F6; Group IV: root canal instrumentation using RB; Group V: root canal instrumentation using WOG; Group VI: root canal instrumentation using F6. Apically extruded debris was collected into preweighed Eppendorf tubes by using the Myers and Montgomery method. Data were statistically analyzed with one-way ANOVA and Kruskal–Wallis tests. Results: All the tested instruments caused the extrusion of debris and irrigant from the apical foramen. The difference among the six groups was not statistically significant (p > 0.05). Conclusions: The tested instruments caused similar apical extrusions of debris and irrigant during CH removal or instrumentation procedures.

Abstract

Chemo mechanical preparation is one of the important stages for successful endodontic treatment, and Boric acid has been proposed as an alternative irrigation solution for root canal treatment. Objective: The purpose of this study was to evaluate the effect of irrigation with boric acid (BA) and EDTA on the mineral content and microhardness of dentin and penetration of the AH Plus root canal sealer. Methods: 63 single-rooted teeth were instrumented. Microhardness analysis, 45 teeth were cut longitudinally and then transversely to obtain dentin. Pre- and post-treatment microhardness values were measured. The samples were randomly assigned into 3 groups (n = 15) for irrigation solution: distilled water, 17% EDTA, and 5% BA. The 18 roots were irrigated with three solutions (n = 6). Nine of the roots were filled with AH-Plus for confocal laser scanning microscopy analysis, and the others were used for XRD analysis. Results: The results were evaluated with the ANOVA test. BA caused a significant decrease in microhardness value in apical and coronal parts (p < 0.05), while EDTA reduced only in coronal parts (p < 0.05). Conclusion: BA provided higher sealer penetration ability. BA reduced the microhardness and provided better sealer penetration.

Abstract

Background: This study aimed to evaluate canal transportation, centering ability, structure model index (SMI), surface area, and root canal volume changes in the mesial canals of mandibular first molars using micro-CT. Methods: Twenty-four mandibular first molars with two separate mesial canals and moderate curvature were included. Teeth were scanned using micro-CT before instrumentation and randomly divided into three groups (N = 8). Root canals were prepared using OneShape, OneCurve, and Rotate file systems, followed by post-instrumentation micro-CT scanning (10µm/pixel resolution). Changes in canal volume, surface area, transportation, centering ability, and SMI were analyzed at the apical, middle, and coronal thirds. Data were statistically evaluated (p < 0.05). Results: Canal transportation was significantly greater in the middle third compared to the apical and coronal regions. OneCurve (0.06 ± 0.02) and OneShape (0.09 ± 0.05) systems showed significantly higher transportation than the Rotate system (p < 0.05). No significant differences were observed among the groups in centering ability (p > 0.05), although the Rotate system demonstrated better centering ability. Additionally, the OneShape system resulted in greater increases in canal volume and SMI. Conclusions: While OneShape and OneCurve systems exhibited similar transportation, the Rotate system provided more favorable shaping outcomes. OneShape caused greater dentin removal and morphological changes.
