The effect of a toothpaste containing aloe vera on established gingivitis.

The aim of the study was to evaluate the effect of a toothpaste containing high concentrations of Aloe vera on the reduction of plaque and gingivitis in patients attending regular dental care by a dental hygienist. Fifteen subjects participated in this randomized, double-blind, intra-individual and controlled clinical study. Participants were non-smokers, with signs of gingivitis (bleeding index 30%) and no signs of periodontitis. Subjects were followed for three 6-month periods during which they used either their own toothpaste, or an Aloe vera or a control toothpaste. Plaque and gingival indices were recorded atthe start and end of each period. There was a statistically and clinically significant reduction of about 20% of the plaque and gingivitis indices at the end of the clinical trial compared to baseline values, but no differences between the Aloe vera and the control toothpaste. It may be concluded that in patients motivated to improve their oral hygiene habits, the use of a toothpaste containing Aloe Vera showed no additional effect on plaque and gingivitis compared to a control toothpaste.
