Objectives: To evaluate a mouth rinse containing tetrapotassium pyrophosphate and sodium tripolyphosphate on supragingival calculus formation in a group consisting initially of forty adults seeking periodontal treatment at a Canadian dental school. Methods: The extent of supragingival calculus in relation to the lingual surfaces of the lower anterior teeth was measured using the Volpe-Manhold Calculus Index (VMI). In addition, The Plaque Index (PI) was used to evaluate plaque scores while the presence or absence of gingival bleeding index (GBI) was used to determine gingival health. At the completion of the hygiene appointment (baseline), the PI, GBI and VMI was assumed to be zero and the subjects were randomly assigned to test (rinsed twice a day with the anticalculus mouthwash) or control groups (only used regular dentifrice) and appropriate instructions provided. After a 60-day trial period, the test and control subjects were recalled, and the clinical measurements were conducted using the indices indicated above. Results: There were no statistically significant differences in the overall reduction in the mean VMI scores between the test and control groups. Conclusion: Within the limitations of the study, rinsing with tetrapotassium pyrophosphate and sodium tripolyphosphate for sixty days did not affect the formation of supragingival calculus in the present cohort of adults. |
