KETKAR, Hindustan Lever, Mumbai, India Objectives:A double-blind, randomised study investigated the effect of regular brushing with natural chalk-based dentifrices on the oral health of an Indian rural population, primarily natural product users. Methods: 196 subjects (18-65 year old adults) were included. The primary outcome variable was gingivitis with debris and plaque as secondary outcome variables. Mean scores for each index were compared between baseline, 9 and 25 week examinations. Test products comprised 5 natural chalk-based dentifrices containing plant extract. A control group was included to track seasonal variations in oral health. Subjects allocated to test product were given oral hygiene instruction (OHI) and asked to use the product once daily as in their current oral regime, and to refrain from use of other oral hygiene products. This group was visited at frequent intervals in their own homes to reinforce OHI and compliance. Subjects in the control group continued with their normal habit and did not receive home visits Results: All product groups showed continuous improvement in oral health over the 25 week study period as measured by gingival bleeding, plaque and debris. For each test product, all changes compared to baseline were significant at p<0.05, the majority at p<0.0001. Sub-analysis of the data revealed that older people and those who had previously not used toothbrush/dentifrice showed the greatest improvement in oral health whilst gender and product form (paste or powder) used had little effect. Conclusions: This study demonstrates that regular brushing with a natural chalk-based dentifrice containing plant extract produced significant improvements in oral health as measured by gingival inflammation, gingival bleeding, plaque and debris accumulation. The improvements are significant compared to a no treatment group and are greatest in older people and those who previously had not used toothbrush/dentifrice. | ||
