Experimental use of a slow release device employing chlorhexidine gluconate in areas of acute periodontal inflammation

Eleven patients suffering acute exacerbations of chronic periodontitis were treated by the insertion into affected periodontal pockets of dialysis tubing containing 20% chlorhexidine gluconate. After 7 days, 9 of the 11 patients exhibited greatly reduced crevicular fluid flow, relief of discomfort and the cessation of bleeding on probing.
