At each of visits, assessed for plaque index, gingival bleeding tendency, pocket depth. Loss attachment between baseline 3 removed tooth loss determined. Complete data obtained 15 14 adults. During treatment adolescent group showed significantly more (p less than 0.05) inflammation supragingival adults; removed, this pattern no longer statistically significant. For attachment, there significant differences among adolescents, with tissues, or reduced but healthy tissues who undergone disease. loss, three nonstudy site teeth pockets deeper 6 mm and/or furcation involvements lost because abscesses adult treated
