Clinical effectiveness of subgingival irrigation with a pulsated jet irrigator versus syringe.
Previous studies have shown clinical and microbiological improvement with subgingival irrigation particularly after scaling and root planing. In this study we monitored the effects of saline irrigation on non-treated periodontal pockets. Ten subjects with severe periodontal disease and symmetrical lesions on multirooted teeth were selected. They had not received periodontal treatment or antibiotics for the previous 6 months. Patients were given simplified oral hygiene instructions. Neither scaling nor root planing was provided during the study. Two teeth were randomly selected per quadrant for subgingival irrigation with saline solution. One side was treated with a syringe and the other side with a pulsated jet irrigator with a modified tip, professionally administered. Clinical parameters (pocket depth, plaque index, gingival index, crevicular fluid, bleeding index, attachment level, and subgingival microflora) were evaluated on days 0, 15, 30, 60, and 90. Both subgingival irrigation products induced changes (reductions) in these indices during the study. Significant differences (P less than 0.001) with the oral irrigator were found for the following parameters: microscopy, pocket depth, crevicular fluid, and plaque index. In this study, professionally administered saline irrigation with a pulsated jet irrigator was more effective than syringe treatment with the same solution. Neither treatment resulted in a detectable gain in probing attachment level. Since gain in attachment level is achievable by other techniques, neither of these subgingival irrigation procedures alone can be considered adequate for periodontal therapy.
