Effectiveness of moringa oleifera leaf extract nanoparticles in cleaning smear layer on the apical third of root canal walls

Abstract

Objective: To evaluate the cleanliness smear layer on the apical third of the root canal wall in teeth irrigated with 5% and 10% Moringa leaf extract nanoparticles. Method: Vitro experimental laboratory with posttest control group design. A total of 30 mandibular permanent premolars were decorated to an average tooth length of 13 mm. The teeth were divided into 5 groups, with 6 samples per group and each sample was irrigated with 5 ml for 5 minutes. Group I (negative control) irrigated with aquadest steril, group II (positive control) irrigated with NaOCl 5,25%, group III (positive control) irrigated with a combination of NaOCl 5,25% and EDTA 17%, group IV (test group) irrigated with Moringa leaf extract nanoparticles 5% and group V (test group) irrigated with Moringa leaf extract nanoparticles 10%. All samples were tested for cleanliness of the smear layer on the apical third of the root canal wall using CLSM. Result: Average score cleanliness of the smear layer on the apical third of the root canal wall the highest are groups IV and V but not significantly different from group III. Groups IV and V were significantly higher than groups II and I, while the lowest was group I. Conclusion: Moringa leaf extract nanoparticles 5% and 10% were effective in cleaning the smear layer on the apical third of the root canal wall.
