To determine the effect on periodontal health of a daily self‐administered irrigation with 0.02% stannous fluoride (SnF 2 ) solution, 28 subjects who had moderate to advanced periodontitis were randomly divided into 3 groups: a control group ( n = 9) which used no irrigation, a group ( n = 8) which used a self‐administered water irrigation device (Water Pik) daily with water (H 2 O group) and a group ( n =11) which used the Water Pik in a similar manner but with SnF 2 solution (SnF 2 group). All subjects were instructed in routine tooth brushing and flossing but received no other periodontal treatment. 4 study sites were selected from each patient which had pocket depths greater than 4 mm and bleeding upon probing. Plaque index, gingival index, bleeding tendency, pocket depth, loss of attachment, and microbiologic samples of subgingival plaque for morphologic determinations were collected from all study sites at baseline, 2, 6, and 10 weeks. A cross‐over was then initiated for 2 additional monthly checks in which the H 2 O group changed to SnF 2 and the SnF 2 group was divided into 2 subgroups which either continued to use SnF 2 or changed to H 2 O. The control group completed the study at the beginning of the crossover. The clinical data showed significantly more improvement in periodontal health during the first 10 weeks for the SnF 2 group ( p < 0.01). After cross‐over, the clinical data indicated the group that changed from H 2 O to SnF 2 significantly improved their periodontal health, while the group that changed from SnF 2 to H 2 O became worse. The microbiologic data showed trends which agreed with the clinical data during the first 10 weeks but were less significant. After cross‐over, the %s of motile rods and spirochetes were too small (0–7%) to establish statistically significant changes considering the accuracy of the technique used.
