This 6-month controlled clinical study demonstrated that the essential oil mouthrinse and the chlorhexidine mouthrinse had comparable antiplaque and antigingivitis activity. Insofar as side effects associated with the chlorhexidine mouthrinse may limit patient compliance, it is suggested that each product can have a distinct role in the management of patients with periodontal diseases.

Using an experimental gingivitis model, 99 subjects completed a 3-week study to determine the correlations between a visual index of gingivitis, the Modified Gingival Index (MGI), and the Gingival Index (GI), the Interdental Bleeding Index (IBI), and the Papillary Bleeding Index (PBI). Following a baseline examination consisting of the MGI and either the GI, IBI, or PBI, each subject received a full mouth scaling and rubber cup polishing to render the teeth plaque and calculus free. Subjects then rinsed twice daily for 30 seconds with 20 ml of either an active antimicrobial or control mouthrinse for 3 weeks while abstaining from all other oral hygiene. The MGI correlated significantly with the GI, IBI, and PBI, both at baseline and at 3 weeks for all subjects.

The results demonstrate that use of the stabilized 0.454% stannous fluoride/sodium hexametaphosphate dentifrice over a 6-month period provided statistically significant reductions in gingivitis, gingival bleeding, and plaque when compared with a negative control dentifrice.

103 adult subjects completed a supervised 2-week double-blind controlled clinical study to determine the effect of using either listerine antiseptic (LA) or its vehicle control (VC), as the only oral hygiene procedure, in inhibiting the development of and in reducing plaque and experimental gingivitis. Following baseline examinations, half-mouth prophylaxes were performed on each subject, who continued normal oral hygiene and returned 4 or 5 days later for a second baseline. Subjects then rinsed, under supervision, either 2 or 4 times daily for 2 weeks with LA or twice daily with VC, but suspended all other oral hygiene measures. Plaque and gingivitis were evaluated at baselines and after 2 weeks. Subjects using LA 2 or 4 times a day as the only oral hygiene procedure for 2 weeks demonstrated highly significant inhibition and reduction of both supragingival plaque and gingival inflammation compared to those using VC.
