[The role of chlorhexidine irrigation combined with ultrasonic root planing in treatment of periodontal disease. Preliminary study].

The beneficial effects of chlorhexidine on plaque formation have been well documented. This study was undertaken to evaluate the dual effects of chlorhexidine irrigation and root planing with an ultrasonic scaler. The parameters measured were plaque and gingival indices and bleeding on probing. A statistically significant decrease in all indices measured was demonstrated when compared with the test group of patients who received ultrasonic scaling and irrigation with sterile water.
