Abstract Objective The purpose of this study was to compare the push-out bond strength of root canal filling with different tapered gutta-percha points of two root canal sealers. Materials and Methods One hundred and twenty mandibular premolar teeth were prepared with a Reciproc blue file to size R50 and divided into four groups (n = 30 per group), with group 1 receiving iRoot SP with 02-tapered gutta-percha point (iRoot02), group 2 receiving iRoot SP with match-tapered gutta-percha point (iRoot50), group 3 receiving canal sealer bioactive glass (CS-BG) with 02-tapered gutta-percha point (BG02), and group 4 receiving CS-BG with match-tapered gutta-percha point (BG50). All samples were stored at 37°C and 100% humidity for 1 week. The specimens were resected at 3.5 and 5 mm from the apex, and push-out bond strength was measured using a universal testing machine. Results iRoot02 had the highest push-out bond strength and differed significantly from iRootR50. BGR50 produced the lowest push-out values and showed no difference from BG02. Conclusions The amount of iRoot SP in the root canal filling influences the material's resistance to pushing out. It will be more resistant if the ratio of iRoot SP to gutta-percha is high. When gutta-percha points with different tapers were used, the amount of CS-BG had no effect on the push-out force.

Background In recent times, there have been significant advancements in the techniques and materials used for root canal treatment. Nevertheless, there is a lack of study on the current methods used for root canal treatment among dentists in Thailand. Therefore, the primary purpose of this study was to investigate the current root canal treatment procedures and the demand for continuing education among Thai dental practitioners. Methods The survey, consisting of two sections and a total of 25 questions, was randomly distributed to 412 dentists in Thailand, both online and offline. Data on demographics, information on current root canal treatment protocols, and demand for continuing education, were collected. The association between demographic data and current root canal treatment protocols was analyzed using the chi-square test. The data gathered were analyzed using the JASP statistical software version 0.18. Results Three hundred and ninety-four questionnaires were completed. Sixty percent of the respondents (236) regularly performed root canal treatment. Most respondents treated one to five anterior teeth weekly. Seventy-six percent of the respondents did not use magnification. Fifty-eight percent of the respondents used an electronic apex locator in conjunction with a radiograph to determine the working length. Forty-four percent of the respondents used hand files for mechanical instrumentation. Sodium hypochlorite was the most used irrigant, while cold lateral compaction was the preferred obturation technique. The participants revealed the most interest in enrolling in two to three-day short seminar courses. Conclusion More Thai dental practitioners strictly followed the standard protocol compared to the previous survey. The short seminar courses were the most preferred program for continuous education.

Introduction. This study aimed to evaluate the efficacy of a formulation of premixed calcium silicate-based sealer (CSBS) with monocalcium silicate (Mono-CS) as the main component. Its properties were compared with those of a control group (iRoot SP) according to ISO 6876/2012 standards for root canal sealers. Materials and Methods. The CSBS formulation consisted of two components (powder and liquid). The powder was a mixture of Mono-CS, a radiopacifier, and a thickening agent, and the liquid components were nonaqueous liquid agent and setting accelerator. Three formulation groups with different powder–liquid ratios were prepared: group A, 2 : 1; group B, 3 : 1; and group C, 2 : 1, which also contained calcium chloride as a setting accelerator. The setting time, flow rate, film thickness, and radiopacity of the three CSBS groups and the control group were evaluated and compared. Each test was repeated five times for each group. Results. The minimum values of setting time (i.e., working time, initial setting time, and final setting time) were ranked in order of significance as group B, the control group, group C, and group A. The control group had the lowest film thickness at 20 μm, with a nonsignificant difference to group C. The flow rates in group A, group C, and the control group were >20 mm. Furthermore, the experimental groups showed a similar amount of radiopacity as the control group (p >0.05). Conclusion. Mono-CS and calcium chloride can be used in the formulation of root canal sealers, and their properties, including working time, initial setting time, final setting time, flow rate, film thickness, and radiopacity, are consistent with those of iRoot SP and ISO 6876/2012 standards.

Objective. This study aims to compare the effects of conventional syringe irrigation (CSI), passive ultrasonic irrigation (PUI), and innovative sonic-powered irrigation (EDDY) on the penetration of sodium hypochlorite (NaOCl) solutions into root canal dentinal tubules at different levels of the root canal. Materials and Methods. One hundred ninety-two extracted first mandibular premolars of 17- to 25-year-old patients were decoronated 13 mm from the root apices and separated into two groups according to apical preparation sizes (APS) 25 and 40. The root canals were dried with a paper point and stained in crystal violet for 72 hours. Each APS group was separated into three groups according to irrigation techniques, as follows: CSI, PUI, and EDDY. Roots were perpendicularly resected to the long axis at three levels (coronal, middle, and apical). Photomicrographs were taken of all three cross-sections of each tooth under a stereomicroscope. The depth of the bleached zone was measured with ImageJ software. The data were analyzed by Welch’s analysis of variance and an independent t-test (p = 0.05). Results No penetration was found at the apical level in the CSI25, CSI40, and PUI25 groups. The EDDY25 and EDDY40 groups showed the most significant penetration at the middle and apical levels compared to the other groups (p < 0.05). Conclusions. Within the limitations of this study, irrigation techniques and APS affect the penetration depth of NaOCl into the root canal dentinal tubules. In terms of irrigation techniques, the penetration was deepest when EDDY was used, followed by PUI and CSI. In terms of APS, NaOCl penetrated deeper into APS40 than APS25. The use of the EDDY irrigation technique in APS25 can improve the penetration of NaOCl into root canal dentinal tubules at the apical level.
