“…On the contrary, significantly higher (p<0.05) microleakage values were observed in positive control samples. This may be because positive control samples constituted biomechanically prepared root canals without obturation and the higher microleakage values are due to the absence of obturation material allowing higher amount of dye to penetrate and is in corroboration with findings of various authors [25,26].…”

Aims: The aim of the present in vitro study was to evaluate apical seal in the root canals containing separated instrument (Hand k files, Hyflex CM and Reciprocation Neoendo file) using dye penetration method. Study Design: An In vitro study. Place and Duration of Study: Department of Conservative Dentistry & Endodontics, SGRD Institute of Dental Sciences, Amritsar, Punjab, India between Feb 2022 and Nov 2023. Methodology: In this study 3 different file systems were used for root canal preparation of 90 teeth. The files were intentionally separated (n=20 each) at the apical third and tooth was obturated using lateral condensation method along with 2 control groups (n=5 each) and the analysis of microleakage was done using dye penetration method under stereomicroscope. Results: The highest mean microleakage was observed in Hyflex CM (5.49mm) group followed by Hand K file (3.338 mm) whereas least microleakage was observed in samples containing separated Reciprocation file Neoendo (3.220 mm). Conclusion: Maximum microleakage was observed in Hyflex CM files and least in Reciprocation File Neoendo group.

“…Endodontic treatment primarily involves chemomechanically preparing the root canal space to facilitate the placement of a biocompatible material that seals the canal throughout its entirety. 1 In doing so, organic material that may decompose and sustain bacterial growth is removed to maintain or restore the health of the peri-radicular tissues. 2 During the shaping of root canals, several irrigation solutions such as sodium hypochlorite (NaOCl), deproteinizing agents, ethylenediaminetetraacetic acid (EDTA), and calcium-chelating agents 3 have been introduced to decrease the residual debris, necrotic tissues, bacteria, and smear layer.…”

Objective: To evaluate the efficacy of XP- endo finisher (XPF) in removing the residual smear layer as a final step following the use of the One Curve and 2Shape files. Methods: Sixty extracted maxillary first molar teeth with (MB) root curvature within (10-25°) were selected, and only (MB) roots were used in this study. After that, the teeth were divided randomly according to the type of file used for canal preparation into two main groups (1 and 2). Then the main groups were divided into three subgroups (A, B, and C). In subgroups A1, B1, and C1, the 2Shape file was used for canal preparation; in subgroups A2, B2, and C2, the One Curve file was used. In subgroups A1 and A2, NaOCl was used during instrumentation and XPF to improve the residual smear layer removal with EDTA. In subgroups B1 and B2, NaOCl was used during instrumentation, and EDTA was used for 1 min to remove the residual smear layer. In subgroups C1 and C2, normal saline was used during instrumentation and with XPF. Then the roots were linearly sectioned into two parts. The coronal, middle, and apical thirds were quantified for the remaining smear layer under the scanning electron microscope (SEM). The Kruskal–Wallis- test and Mann- Whitney U test were used to measure the subgroups' differences. All tests were performed at the significant (p < 0.05) level. Results: The subgroup C1 had the highest mean score and lowest efficiency in removing the residual smear layer. The result showed that the subgroup A2 exhibited the best residual smear layer removal effectiveness. Significant differences were observed between subgroups A1 and A2 (p < 0.05). At the same time, there were significant differences between subgroups B1 and B2 (p < 0.05), and subgroups A2 and B2 exhibited significant differences from C2 (p < 0.05). Furthermore, significant differences were observed when subgroups C1 and C2 were compared to all the other subgroups (p < 0.05). Conclusions: Using the One Curve file with NaOCl during instrumentation and using XPF to improve the residual smear layer removal with EDTA exhibited the best efficacy for removing the residual smear layer.

Background and objective: The aim of this in vitro study was to assess the efficacy of photodynamic disinfection against Enterococcus faecalis, and compare it with the effect of different endodontic irrigant activation techniques. Methods: Fifty single-rooted premolars with single canals were chosen for the study. Five teeth were chosen to serve as the negative control group. The remaining samples were infected with normal Enterococcus faecalis strains. They were then randomly separated into five groups, with nine teeth serving as a positive control group (E. Cont.). Each group consisted of 9 samples based on the kind of irrigant activation: E.A (Diode laser), E.B (Ultrasonic), E.C (conventional), and E.D (FotoSan). The ProTaper NEXT rotary system up to model X3 was used to prepare all samples. For each group, 5.25% NaOCl was injected as an initial irrigant with a 30G double-side vented syringe needle, followed by 17% EDTA, then activated with NaOCl as a final irrigant. CFU of each sample was counted before and after irrigation regime, and they were compared to the control group. The efficiency of the disinfection techniques was determined using scanning electron microscopes (SEM). Result: The quantity of bacterial colony counting revealed that the control group had the largest mean of a bacterial colony (135.56±50.58); while the FotoSan group had the lowest colony mean number (23.11±9.82). SEM results indicated that the FotoSan group (5.56±3.16) and Diode laser (5.56±3.57) had the lowest surviving colony mean number. Conclusion: As an additional method, photodynamic therapy may increase the disinfection capacity of traditional endodontic treatment against E. faecalis in the root canal.
