Comparative Evaluation of Push-out Bond Strength of AH Plus Sealer toRadicular Dentin after using EDTA and Different Herbal Agents as Final RootCanal Irrigants: An In Vitro Study

AimnbspTo evaluate and compare the push-out bond strength PBS of AH Plus sealer to radicular dentin treated with ethylenediaminetetraacetic acid EDTA neem leaf extract NLE and apple cider vinegar ACV as final root canal irrigants. nbspMethodsnbspThirty-six extracted human permanent single-rooted teeth were decoronated and instrumented using the Protaper Universal rotary system up to size F3. The samples were randomly assigned into three groups n 12 based on the final irrigant used Group I - 17 EDTA Group II - NLE and Group III - ACV followed by a final rinse with saline. Canals were dried and obturated using AH Plus sealer and F3 gutta-percha cones. After 24 hours each root was sectioned into 3-mm thick slices coronal middle and apical thirds. PBS was assessed using a universal testing machine at 1 mmmin crosshead speed. Data were analyzed using one-way ANOVA and Tukeyrsquos post-hoc test.nbspResultsnbspEDTA exhibited the highest PBS in the middle and apical thirds compared to NLE and ACV while NLE demonstrated significantly greater bond strength in the coronal third.nbspConclusionnbspEDTA showed superior PBS overall making it the most effective final irrigant among those tested. However neem leaf extract demonstrated promising results in the coronal region and may serve as a viable herbal alternative. Further clinical studies are warranted to validate and standardize the use of herbal irrigants in endodontics.
