A chairside microbiological evaluation using the BANA test after a single subgingival irrigation with 1.64% SnF2...

In this study, the adjunctive effects of subgingival irrigation by 1.64% stannous fluoride after subgingival scaling were evaluated in 10 patients with moderate periodontal disease. Three pockets related to single rooted teeth, each in a separate quadrant were monitored in each patient. After proper subgingival scaling, one pocket was irrigated by 1.64 SnF2, the other pocket by saline and the third pocket was left without irrigation. Subgingival plaque samples were evaluated by BANA test and clinical indices were taken at baseline, immediately after subgingival scaling with and without adjunctive subgingival irrigation using SnF2 and saline, and one week after treatment. The results were compared at the different time intervals and it was found that 1.64% SnF2 irrigation after subgingival scaling gave the best clinical indices and least microbiological values using the BANA test throughout the study, followed by subgingival scaling together with saline irrigation, which were better than subgingival scaling without irrigation only right after irrigation, and was insignificantly different from scaling after one week.
