Perbedaan Pengaruh Bahan Irigasi Ekstrak Etanol Daun Belimbing Wuluh (Averrhoa bilimbi L.) 6,25% dengan Sodium Hipoklorit (NaOCl) 2,5% dan Ethylene Diamine Tetra-Acetic Acid (EDTA) 17% dalam Membersihkan Smear Layer pada Dinding Saluran Akar (Studi SEM)

Abstract

The use of irrigation materials is an important factor in root canal treatment to remove the smear layer formed during instrumentation and eliminate bacteria in the root canal. Currently available irrigation solutions do not meet the ideal requirements for irrigation materials. Wuluh starfruit leaf is a natural material that can be developed as an irrigation material because it has saponins as a cleanser and flavonoids, tannins, alkaloids as antibacterial. This research is a laboratory experimental research with post-test only control group design using 28 samples divided into 4 groups. Group I ethanol extract of wuluh starfruit leaves 6.25%, group II NaOCl 2.5% + ethanol extract of wuluh starfruit leaves 6.25%, group III ethanol extract of extract of wuluh starfruit leave 6.25% + EDTA 17%, and group IV NaOCl 2.5% + EDTA 17%. Preparation was performed using AF F One Blue Rotary File with pressureless crown-down technique. The samples were irrigated according to the treatment group with positive pressure technique using a two-side vented 30G needle, and activated ultrasonically. The treated samples were sectioned and tested using a scanning electron microscope (SEM) on the apical third at 2000x magnification. Assessment of the smear layer removal score was performed based on the Torabinejad score index (2003). Data were analyzed using Kappa, Kruskal-Wallis, and Mann-Whitney tests. The results showed that there was a difference in the ability between irrigation groups in removing smear layer in the apical third (p<0.05). Wuluh starfruit leaf extract 6.25% + EDTA 17% had the best ability to remove smear layer compared to the other two groups, but not as good as NaOCl 2.5% + EDTA 17%.
