摘要: This study compared the surface characteristics of periodontally diseased singlerooted human teeth extracted after treatment with either tetracycline HCl or citric acid solutions. The group was comprised 30 from 22 patients advanced periodontal disease before start therapy. Diseased surfaces were identified, outlined, and root planed by hand curet finishing bur. sectioned solutions (pH 1) applied to cotton pellets for 5 minutes. Extracted processed samples then examined scanning electron microscope. both acidtreated sets specimens differed considerably treated planing alone, regardless method. Acid-treated exhibited dentinal tubules exposed removal smear layer, devoid debris normally present in planed-only specimens, dense network col...
