Effects of Subgingival Irrigation With Chlorhexidine on the Periodontal Status of Patients With HA-Coated Integral Dental Implants

The purpose of this study was to examine the effect of chlorhexidine irrigation on the periodontal status of patients with HA-coated dental implants as measured by clinical, microbiological, and immunological measures. Thirty non-adjacent implants were randomly assigned to receive a one-time irrigation with either 0.12% chlorhexidine or sterile saline, or no irrigation. All parameters were measured at baseline, 2, 5, and 8 weeks. Results showed no significant differences between any treatment modalities at any time interval. A statistically significant decrease in probing depth (P .05) occurred within the chlorhexidine and no treatment groups at all time intervals compared to baseline.
