Abstract
- The retention of chlorhexidine in the oral cavity after rinsing with 10 ml 0.2 % [14C]-chlorhexidine-digluconate for 1 min was found to be 3.8 mg (S.D.= 1.4 mg) in a group of 12 edentulous patients. By comparison, the mean oral retention in 10 dental students with cleaned and polished teeth was 4.6 mg (S.D.=0.7 mg). Measurement of the retention in 6 subjects before and after extensive tooth extractions showed no major influence of the teeth on the chlorhexidine retention. Plaque accumulation for 6 d increased the mean Plaque Index from 0 to 0.82 (S.D.=0.35). The corresponding mean oral retention increased significantly from 4.6 mg (S.D.=0.7 mg) to 5.6 mg (S.D.=1.1 mg). Chlorhexidine was readily bound to acrylic resin dentures. A mean binding of 4.2 mg (S.D.= 2.0) after 16 min immersion in 110 ml 0.2 % chlorhexidine solution was found. The [14C]-activity of the saliva showed a sharp fall during the first few hours after insertion of the dentures, followed by a slow release, with activity still present after 24 h.
