Abstract

Aim: The aim of the present study is to analyze the efficacy of root surface smear layer removal between 17% ethylenediaminetetraacetic acid (EDTA) and erbium, chromium:yttrium-scandium-gallium-garnet (ER, CR:YSGG) laser after root planing. Materials and methods: A total of 30 single-rooted teeth extracted due to periodontal disease were selected and randomly allocated into three groups (n = 10 in each group) and root planing was done at the site of interest with Gracey curettes. Group I was taken as control and treated with 10 mL of normal saline, group II was treated with 17% EDTA, and group III was treated with ER, CR:YSGG laser. The samples were processed, fixed, viewed under a field emission scanning electron microscope (FESEM), and analyzed for the presence of a smear layer. The data was statistically analyzed by applying the Kruskal–Wallis test. Results: There was a significant difference (p-value < 0.001) in the efficacy of smear layer removal between all three groups, with mean ± standard deviation of 6.30 ± 0.82 in group I, 4.20 ± 0.63 in group II, and 1.90 ± 0.74 in group III. Conclusion: The root surface smear layer removal is more efficient in the group treated with ER, CR:YSGG laser than 17% EDTA. Clinical significance: Removal of the smear layer on the root surface provides a hospitable environment for periodontal regeneration. It also exposes the collagen fibrils and opens the dentinal tubules, which favors cell migration and attachment.
