A total of 55 subjects (mean age = 31.42 yrs.) received a professional prophylaxis in randomly assigned contralateral quadrants and were then stratified into two balanced groups based on screening plaque scores: one group (27 subjects) used the placebo rinse, the second group (28 subjects) used the test mouthrinse (0.63% diluted to 0.1% stannous fluoride). Plaque index (PI) and stain index (SI) were scored at baseline, week 1 and week 3. Gingival inflammation (GI) was monitored as a measure of product irritancy potential. The PI for the stannous fluoride rinse was significantly lower than the placebo, (p < 0.0001), for both prophied and unprophied sites with an average reduction of 29% at week 1 and 28% at week 3. There was no statistically significant difference between the presence or absence of prophylaxis.

During the pre-test phase, 247 teachers were examined for presence of calculus on the lingual surfaces of the 6 lower anterior teeth, using the Periodontal Probe Method of Calculus Assessment (Volpe et al. 1965). Statistical methods employed were the two-way analysis of variance as well as the paired and unpaired t tests. The level of statistical significance chosen was p less than 0.05. At the end of the 3-month pre-test phase, 88 candidates with the highest calculus index scores met the initial criteria and were stratified into two balanced groups based on their age and sex. Each group received an oral prophylaxis and participants were assigned to use either the dentifrice containing the pyrophosphate or the MFP and instructed to brush their teeth twice daily at home for the next 3 months (test phase). The results showed that the group using the pyrophosphate dentifrice experienced a 20% greater reduction in calculus formation when compared to the MFP control There was also a greater number of calculus-free subjects and tooth surface sites in the soluble pyrophosphate group.

Sixty adult subjects with gingival inflammation were assigned randomly to two groups. The control group were those subjects that used the nylon waxed floss and the test group were those subjects that used the PTFE-type floss. At 0, 2, 5, and 6 weeks, the patients were scored for plaque (PI), gingivitis (MGI), and interproximal bleeding sites (BI).
