This study examined the effects of ultra-long hydroxyapatite nanofibers on bisphenol A-glycidyl methacrylate (Bis-GMA)/ urethane dimethacrylate (TEGDMA) dental resin. Experimental composites incorporating 2 wt% to 8 wt% ultra-long hydroxyapatite nanofibers were assessed for their mechanical properties, ion release behavior, and cytotoxicity. The results indicated that the addition of 2 wt% or 4 wt% nanofibers significantly enhanced the mechanical attributes of the composite materials, whereas higher concentrations led to a deterioration in performance. Moreover, these materials demonstrated the release of Ca2+ and PO43− ions in both artificial saliva and lactic acid solutions, evidencing satisfactory cytocompatibility. The acquired data were subjected to statistical analysis via analysis of variance (ANOVA), with differences deemed statistically significant at p<0.05. Therefore, ultra-long hydroxyapatite nanofiber composites emerge as a promising innovative option for dental restoration.
