ABSTRACT
Smear layer is a thin layer formed due to friction of endodontic instruments during preparation. The smear layer must be removed with root canal irrigation material, namely 2.5% NaOCl. However, 2.5% NaOCl causes toxic effects when pushed into the periapical, so natural materials are needed as an alternative, one of which is green okra fruit extract. The purpose of this study was to analyze the ability of green okra fruit extract to remove the smear layer on the root canal wall. This study was an experimental laboratory study with a posttest only control group design. There were two test groups used, namely 2.5% NaOCl solution (group A) and 12.5% green okra fruit extract (group B), each as many as 5 pieces. The samples used were maxillary premolar teeth cut at the cervical level of the tooth. The root sample was embedded in a red wax block, then the root canal was prepared using conventional techniques up to K-file #50. The root canal was irrigated with 2.5% NaOCl solution and 12.5% green okra fruit extract at each instrument change, then re-irrigated with distilled water and dried. The part observed with Scanning Electron Microscope (SEM) was the middle third of the root canal. The results of SEM photography were calculated based on the Hülsmann scoring system and data analysis was performed using the Mann Whitney U Test statistical test. The results of the study and data analysis showed p = 0.606 which indicated no significant difference in the two sample groups. Both groups had a mode score of 3 which means that the smear layer covered most of the root canal walls, there were no or only a few open dentinal tubules, so it can be concluded that 12.5% green okra fruit extract and 2.5% NaOCl. the solution has the same effectiveness in removing the smear layer on the root canal walls.
