Effect of a combination of amine/stannous fluoride dentifrice and mouthrinse in periodontal maintenance patients

AIM: The purpose of the present study was to evaluate the beneficial effect of using a dentifrice and mouthrinse containing amine fluoride (AmF) and stannous fluoride (SnF(2)) in a group of periodontal maintenance patients. Efficacy parameters were plaque, gingival inflammation, pocket depth and attachment loss. An additional parameter was development of stain. MATERIAL AND METHODS: In total, 80 patients who had been treated for moderate-to-severe periodontitis agreed to participate in this study. Subjects received supportive periodontal therapy at regular intervals of 3-4 months for at least a period of 1 year. The patients were randomly divided into two groups: (1). the test group used an AmF/SnF(2) dentifrice and mouthrinse and (2). the control group used a sodium fluoride (NaF)-containing dentifrice and mouthrinse. Clinical assessments were performed at baseline, 3, 6, 12, 18 and 24 months. RESULTS: The mean plaque index score after 3 months in the test group (0.24) was significantly lower than that in control group (0.34) (p
