| Abstract |
| Objectives: Smear layer is produced during root canal preparation. This layer limits the penetration of disinfecting irrigants into the dentinal tubules and acts as barrier between the obturating materials and root canal wall. Irrigation of the root canal with sodium hypochloride (NaOCl) followed by Ethylene diamine tetra-acetic acid (EDTA) is the gold standard technique for effective removal of smear layer but it may negatively affect the dentin and the periapical tissues. So, the aim of this study was to evaluate the efficacy of apple, dates and pomegranate vinegars for smear layer removal from dental root canals compared with the gold standard (NaOCl/EDTA). Mateials & Methods: Twenty five extracted premolar teeth were grouped into five groups and the root canals of each group were irrigated with the corresponding irrigant and then scanned with scanning electron microscope to calculate the percentage of open dentinal tubules using the image processing software ImageJ. Results: All tested vinegars significantly removed the smear layer compared to the control group. NaOCl/EDTA exposed the highest percentage of dentinal tubules with no statistically significant difference compared to dates vinegar. Conclusion: Dates vinegar may be a substitute for NaOCl/EDTA for smear layer removal from root canals. It seems that vinegars’ ability to remove smear layer is related to their content of organic and phenolic acids rather than their pH value. |
