SUMMARY A clinical investigation was done to determine the comparative efficacy of an experimental dentifrice, containing sodium bicarbonate, sodium chloride, zinc chloride, and sodium fluoride, with a control dentifrice on plaque accumulation and gingival inflammation. Fifty individuals participated in the study; 25 persons were randomly assigned to the control and experimental groups, respectively. The study was done using a double‐blind protocol. Paired data t ‐test analysis was done to determine if statistically significant reductions in plaque accumulation and gingival inflammation had occurred after the 30‐day test period, and if significant differences existed between the control and experimental groups. Both groups showed a statistically significant reduction in their gingivitis and plaque scores. Comparison of the two groups indicated a 52% greater reduction in gingival inflammation by the group using the experimental toothpaste. The ability of the two dentifrice formulations to remove plaque, however, was similar.
