Fibrin (Fg) or chitosan-fibrin hydrogels (Ch) were prepared using 12.5mg/mL fibrinogen and 0.4% (w/v) chitosan. Triple antibiotics, clindamycin-modified triple antibiotic paste, or double antibiotics were loaded in gels (1mg/mL). Antibacterial effect against E. faecalis biofilm was determined by using colony-forming units (CFUs) and confocal laser scanning microscope (CLSM). Cell viability and morphology were determined by loading cells into different gels at 7 and 14 days using the water-soluble tetrazolium salt-1cell viability assay and Live & Dead cell analysis. Mineralization was detected by using alkaline phosphatase and alizarin red staining activity. Antibiotic-loaded Fg gel and Ch gel alone without antibiotics resulted in a significant reduction in CFUs coars to enhance the antibacterial properties while maintaining higher cell viability, cell spreading, and mineralization activity, compared with all the other scaffolds investigated.With the adoption of limited-volume cone beam computed tomographic (CBCT) imaging in dentistry, high resolution of the maxillomandibular complex has led to the recognition of numerous accessory neurovascular canals. The preoperative identification of these structures is essential to facilitate the safe performance of an assortment of invasive dental procedures; however, there is limited information in the endodontic literature regarding mapping of these neurovascular canals and their anatomic variants. To emphasize the utility of accessory neurovascular channel mapping in conjunction with endodontic therapy, we have presented the clinical findings of 4 diverse cases. Comprehensive evaluation of the CBCT scans showed relevant underlying etiopat
