Abstract

Aim It was aimed to evaluate the effect of a continuous chelation protocol (HEBP/NaOCl) on the microhardness and roughness of Biodentine used for root perforation repair. Material and method Biodentine discs (N=76; 5 mm × 2 mm) were fabricated per manufacturer’s instructions and finished under standardized conditions. Specimens were randomly assigned (n=19/group) to: distilled water (control), 2.5% sodium hypochlorite (NaOCl), 9% etidronic acid (HEBP), and mixed HEBP/NaOCl; all exposures were 5 min (10 mL). Samples were rinsed with distilled water, then incubated at 37 °C/100% humidity for 24 h. Surface roughness and microhardness of the specimens were measured. Data were analyzed using one-way ANOVA with Tukey and Kruskal–Wallis with Dunn–Bonferroni (α=0.05). Results The HEBP/NaOCl group exhibited the lowest microhardness values among all groups (p<0.001). The HEBP group did not differ significantly from NaOCl for microhardness, yet both were lower than distilled water, with a significant reduction detected for HEBP versus distilled water (p<0.05). For surface roughness (Ra), NaOCl presented the highest values, differing significantly from distilled water, HEBP, and HEBP/NaOCl (p<0.05). No significant differences in Ra were detected among distilled water, HEBP, and HEBP/NaOCl. Conclusion Although combined protocols may offer procedural advantages, the irrigation regimen for perforation repair should be tailored to the biomaterial’s composition and, when feasible, its maturation state. The concentration of HEBP and contact time should be selected conservatively, consistent with the properties of the calcium-silicate cement employed.
