Special Issue Information

Dear Colleagues,

Over the past decade, we have witnessed significant progress in terms of research and treatment protocols, innovative materials, and techniques in the field of endodontics and endodontic microsurgery, ranging from intracanal medications, irrigating solutions, sealers, microsurgery materials, and nickel–titanium files to cutting-edge equipment like microscopes and cone beam computed tomography with dynamic navigation tools. These introductions have advanced the landscape of treatments, prompting clinicians to adapt their workflows and develop new protocols, ultimately enhancing the standard of care provided to patients.

This Special Issue endeavors to present a comprehensive overview of the recent research and applications of these materials and equipment. The scope of this Special Issue is intentionally broad, encompassing a diverse array of topics and perspectives within the realm of endodontics and endodontic microsurgery. This includes not only vital and non-vital pulp therapies but also extends to areas such as endodontic microsurgery, intentional replantation, education and research, and complex interdisciplinary strategies involving prosthodontics, periodontology, and orthodontics, such as crown lengthening, orthodontic extrusion, and intricate restorations.

It is with great pleasure that I extend an invitation to you to contribute to this Special Issue. We welcome submissions of clinical research and reviews that will further enrich the discourse and advance our understanding of these transformative developments in endodontic and restorative practices.

Abstract
Background and Objectives: Successful endodontic treatment requires thorough disinfection and removal of the smear layer to prevent reinfection. However, conventional irrigants like sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) can compromise dentin integrity.

Background and Objectives: Successful endodontic treatment requires thorough disinfection and removal of the smear layer to prevent reinfection. However, conventional irrigants like sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) can compromise dentin integrity. This study assessed the efficacy of the Synergistic Microbicidal and Ablative Root canal Technique (SMART), which integrates AromaRoot, a biocompatible irrigation solution based on quaternary ammonium compounds, with 980 nm diode laser activation, to enhance bacterial reduction and smear layer removal. Materials and Methods: Sixty extracted single-rooted human teeth were inoculated with Enterococcus faecalis and divided into four treatment groups using NaOCl, AromaRoot, and 980 nm laser, either alone or in combination. Bacterial counts were measured as colony-forming units per milliliter (CFU/mL). For smear layer analysis, 56 extracted teeth were prepared and irrigated using EDTA, AromaRoot, and laser activation, followed by scanning electron microscopy to evaluate dentinal tubule exposure. Data were analyzed using Kruskal–Wallis and ANOVA. Results: The combination of AromaRoot, NaOCl, and laser activation achieved a 99.00% bacterial reduction (from 8082 to 60 CFU/mL, p < 0.001), outperforming NaOCl alone (98.34%, 131 CFU/mL). For smear layer removal, AromaRoot with laser achieved 78.5% open dentinal tubules in the apical third, significantly higher than EDTA alone (64.5%, p < 0.05), though EDTA remained superior in the coronal third (89.0% vs. 81.0%, p > 0.05). Conclusions: The SMART technique significantly improves both disinfection and smear layer removal in root canal therapy, particularly in the apical region. These findings suggest that AromaRoot, especially when laser-activated, may serve as a safe and effective alternative to conventional irrigants, warranting further clinical evaluation. Full article
