Aim and background: The study aimed to assess the antimicrobial efficacy of 11% alcoholic extract of propolis and 9% etidronic acid against Enterococcus faecalis (E. faecalis) in endodontically treated necrotized primary teeth. Methods and materials: A total of 30 necrotic primary molars, either maxillary or mandibular teeth in children of age 3–8 years, were randomly included, of these 15 teeth were irrigated with 11% alcoholic extract of propolis (group I) and 15 teeth with 9% etidronic acid (group II); two microbiological samples with sterile paper points were taken from within the canal in both groups, first sample after the access opening and before first irrigation (S1), and another sample after final irrigation and debridement of infection, before obturating the tooth (S2). All samples (S1 and S2) were evaluated for the presence of E. faecalis by colony-forming units per milliliter (CFU/mL). Results: In group I, a statistically significant decline in CFU/mL (p < 0.05) was observed in samples before and after irrigation. The same results were obtained with group II, with a statistically significant decline of CFU/mL (p < 0.05). Among both groups, after irrigation, a statistically significant decline was noticed in support of 9% etidronic acid. Conclusions: The 9% etidronic acid exhibited a greater decrease of CFU/mL against E. faecalis than that observed with an 11% alcoholic extract of propolis. Hence, etidronic acid can be proposed as an alternative irrigant for necrotic primary teeth.
