Comparative Evaluation of Sealing Ability of Mineral Trioxide Aggregate and Biodentine Used for Root Furcation Perforation Repair – A Systematic Review"
No full textIntroduction: During endodontic operations, furcation perforations are a serious complication that might jeopardize periodontal health and the affected tooth\u27s long-term prognosis. To stop microbial leaking and encourage periodontal repair, these perforations must be properly sealed. Because of its sealing capabilities and biocompatibility, Mineral Trioxide Aggregate (MTA) has long been regarded as the gold standard for furcation healing. A more recent calcium silicate-based substance called biodentine has gained attention as a possible substitute because of its advantageous physical characteristics and bioactivity.
Objectives: The aim of the present systematic review is to evaluate and compare the sealing ability of Mineral Trioxide Aggregate and Biodentine when used for the repair of root furcation perforations.
Methods: A comprehensive electronic search was carried out across databases such as PubMed, Scopus, and Google Scholar. The included studies compared the sealing capabilities of MTA and Biodentine in the repair of furcation perforations by in vitro or ex vivo experimental investigations. Two reviewers independently carried out the data extraction and quality assessment in accordance with PRISMA criteria.
Results:The majority of the included research evaluated the effectiveness of sealing using spectrophotometric, fluid filtration, dye penetration, or bacterial leakage techniques. Although MTA and Biodentine both showed adequate sealing capabilities, a number of studies found that Biodentine performed better or on par with MTA in terms of marginal adaption and decreased leakage.
Conclusions: Root furcation holes can be successfully repaired using both mineral trioxide aggregate and biodentine. Although MTA is still often used, Biodentine seems to provide a similar sealing capacity combined with benefits like quicker setting time and better handling. To confirm these results and encourage evidence-based material selection in clinical practice, more standardized clinical and in vivo research is advised
Stereomicroscopic Evaluation of Dentinal Microcracks After Instrumentation of Curved Canal with Rotary Files in Two Motions
No full textObjective: This study aimed to examine the effects of three distinct file systems with two motion types—rotary and reciprocation—on the development of dentinal microcracks after root canal preparation using a stereomicroscope. Methods: Sixty mandibular molars with a curvature of 30° were decoronated and divided into three groups (Vortex Blue, Mtwo, and ProTaper Next) and two subgroups (rotary and reciprocating motions). The samples were then instrumented with the files, dyed with 1% methylene blue dye, and sectioned horizontally at 3, 6, and 9 mm from the root apex. The dentinal microcracks were inspected using a stereomicroscope at 40× magnification. One-way analysis of variance and post hoc Tukey tests were used to perform statistical analysis. Results: Crack formation was statistically significant at the 6-mm and 9-mm levels from the root apex in both motions (p \u3c 0.05). Among all the file system, Vortex Blue caused the highest dentinal microcracks in both motions at 6 mm from the root apex. Conclusion: The reciprocating motion resulted in fewer dentinal microcracks than the rotary motion. All file systems caused significant dentinal microcracks at the curvature of the root canal during both motions. Dentinal microcrack formation was not significant at the root apex
An in Vitro Study on Effect of Commonly used Eucalyptus and Chlorhexidine based Mouthwash on Surface Roughness of Universal Nanohybrid Composite and Light Cure Glass ionomer Cement.
No full textIntroduction: The popularity of esthetic tooth-coloured restorations has increased as a result of high demands for pleasing appearance and patient concerns about the use of restorations which are not tooth coloured. These high demands led their wide use in restoring the carious and non- carious cervical lesions.
Material & Methods: Universal nanohybrid composite (3M Filtek Z250) and Light cure Glass ionomer cement (GC Fuji II LC) were used as a restorative material. Total 30 specimens were tested and divided into three groups based on different mouthwashes. Teflon mold of 8 mm diameter and a 2 mm thickness, samples of each material were prepared. Overflow of excess material was achieved by placing a transparent mylar strip. In order to ensure smoothness and light refraction, glass surface was used. Both the restorative material were light cured with LED light (Woodpecker, Mainland, China) according to manufacturer’s instructions. Then the specimens were polished subsequently with coarse, medium, fine and super fine polishing disc of Super snap polishing kit (Shofu, Kyoto, Japan) according to manufacturer’s instructions by using a low-speed handpiece at a rpm of approximately 12000-14000. Surface roughness was then tested using surface profilometer (Surftest 211, Mitutoyo, Tokyo, Japan).
Results: One-way analysis of variance (ANOVA) was performed. While the Wilcoxon test was used for paired comparison of the data before and after immersion. All the data were evaluated with 95% of confidence p> 0.05.
Conclusion: Hence within the limitations of this study, there was no significant differences between the materials before and after immersion in mouthwashes. This is of utmost importance as any surface roughness can lead to plaque accumulation and bacterial retention

Management of Permanent Teeth with Open Apex: Mta Vs Regenerative Treatment: A Systematic Review
No full textIntroduction: Trauma or caries in immature permanent teeth often leads to pulpal damage, interrupting root development and increasing the risk of fractures due to shorter roots with thin walls. Traditional approaches like calcium hydroxide apexification or mineral trioxide aggregate (MTA) apexification have shown success in controlling infection and creating an apical seal. However, these methods may result in abnormal root morphology and leave teeth vulnerable to fractures. Regenerative endodontics offers a biological alternative, aiming to restore damaged structures, enhance root development, and promote apical closure. Despite promising outcomes, variability in results and limited evidence leave the comparative efficacy of apexification and regenerative techniques unresolved, necessitating further research to guide clinical decision-making. .
Objectives: To compare the clinical outcomes of MTA apexification and regenerative endodontic procedures in managing immature permanent teeth with open apices.
Methods: We conducted an electronic search in PubMed,Ebsco and Cochrane databases to identify clinical cases related to the assessment of apexification using MTA and regenerative treatment procedures in immature permanent teeth (PICO Question: What are clinical outcomes of MTA and Regenerative endodontic procedures in management of permanent teeth with open apex? )
Results: Both MTA apexification and regenerative endodontic procedures demonstrated comparable efficacy in treating immature permanent teeth with open apices. MTA reliably achieved apical closure and barrier formation, while regenerative techniques, especially with PRF, showed potential for root lengthening and dentinal wall thickening. However, variability in study designs highlights the need for further research to establish definitive success rates.
Conclusions: Both MTA apexification and regenerative techniques are effective for managing immature permanent teeth with open apices. MTA offers reliability in achieving apical closure, while regenerative approaches, particularly with PRF, show promise for enhanced tissue regeneration. Further studies are needed to determine long-term success and establish definitive guidelines

Analyzing the Effectiveness of Different Methods for Instrument Retrieval: A Comprehensive Systematic Review
No full textIntroduction: The rate of success of retrieval of instruments that have been fractured differs because it depends upon several variables, such as the visibility of the broken instrument, the size of the broken instrument relative to the canal\u27s curvature, and the methods used in every instance. The separation of endodontic instruments in the intracanal area can hinder shaping and cleaning processes in the canal and could negatively affect the procedure results. This descriptive analysis of distinct instruments set out to (1) look over the research concerning treatment options, influences aspects, and complications. (2) propose the best method for the management of these instruments..
Methods: Research was conducted through peer-reviewed journals in PubMed, Lialac, Ebsco, ProQuest, open gray, and J gate to locate experiments and clinical studies and reviews, by utilizing the key phrases Instruments, Files obstructions, fractured or broken instruments, separation removal, retrieval treatment, bypassing, as well as problems with or without the endodontic canal or root canal.
Results:. The results show an absence of evidence at a higher level about properly managing separate instruments. The conventional conservative treatment includes eliminating or avoiding the fracture or filling the root canal system to an extent that is coronal to the fragment. The surgical procedure is an option. This is influenced by several aspects and could be linked with issues. Based on recent clinical research an approach to decision-making for treatment is recommended.
Conclusions: This comprehensive review provides insights from laboratory studies that examine the correlation between the curvature of root canals and the specific location where instrument fractures occur, offering valuable insights into their impact on overall treatment success. Significantly, the ultrasonic approach demonstrated the most favorable outcomes. It underscores the importance of anchoring clinical practice in rigorously conducted clinical trial
Accuracy of the integrated electronic apex locator in locating simulated perforation under various irrigating solutions in an in vitro study
No full textAim: This study’s objective was to assess the accuracy of the integrated apex locator in identifying artificial root canal perforations in the presence of saline, chlorhexidine, sodium hypochlorite, QMix, and MTAD. Methods: The root canals of 60 single-rooted extracted human teeth were perforated artificially at a point 10 mm away from the root apex. After measuring the actual lengths up to the perforation point, the teeth were then put within an alginate mould for measurements using an integrated apex locator. Using a #20 K-file in the presence of NaCl, CHX, MTAD, NaOCl, and QMix, an electronic apex locator was used to measure the perforations electronically in accordance with the manufacturer’s instructions. Between the measurements, each canal was dried with paper points after being irrigated with distilled water. The accuracy of all the readings was calculated at ± 0.5 mm. Statistical analyses were performed using the Z-test. Results: In comparison to the MTAD, NaOCl, and Qmix, saline and chlorhexidine scored more readings in the ± 0.5 mm range of the perforation site, and the difference was statistically significant. Conclusion: The most precise electronic measurements of artificial perforation were obtained in the presence of chlorhexidine or saline
Working length determination: Comparative analysis of integrated & electronic apex locator in various irrigating solutions
No full textIntroduction: Working length (WL) determination is one of the crucial steps in endodontic treatment. Conventional Apex locators (EAL) are consistently employed nowadays for WL determination. Apart from the EAL, Integrated apex locators (IAL) have also come into the market that aim to reduce the number of steps. Objectives: The objective of this in vitro study was to compare and evaluate the accuracy of Eighteeth E-Connect S (IAL) and Root ZX Mini (EAL) in two different irrigating solutions. Methodology: Thirty freshly extracted, single-rooted teeth were taken. The teeth were then individually mounted on an alginate mould. The measurements of the mounted samples of both the groups were taken accordingly based on the irrigating solutions. WL determination was done one by one with both Conventional Apex locator & Integrated apex locator, respectively in 3% sodium hypochlorite (NaOCl) and 2% Chlorhexidine (CHX). Statistical analysis was performed using One Way ANOVA test. Results: The test results showed that there was no statistically significant difference between EAL & IAL in both groups when compared with the actual WL. Conclusion: Both ALs were equally effective in determining WL at ±0.5mm from the apex in the presence of irrigating solutions, i.e., NaOCl and CHX
