The purpose of this investigation was to determine the main and interaction effects of two oral hygiene regimens and periodontal instrumentation on the periodontal health status of subjects between the ages of 18 and 70 over a two-month period. The sample consisted of 16 subjects with moderate periodontitis. A split-mouth design was used; subjects brushed with fluoridated toothpaste on one side of the mouth and brushed with a hydrogen peroxide-sodium bicarbonate paste on the contralateral side. For each treatment, scaling and root planing were randomly assigned to one arch. At two-week intervals, the periodontal health status was measured using the Gingival Index and periodontal probe measurements. A two~way analysis of variance was used with alpha set at 0.05. Results showed that quadrants treated with scaling and root planing had more significant reductions in both Gingival Index scores and pocket depths than quadrants treated without scaling and root planing. No statistically significant differences, however, were noted between brushing with fluoridated toothpaste and brushing with a hydrogen peroxide-sodium bicarbonate paste.
