The effect of three dentifrices and a dental gel on plaque formation: a six week clinical study.

A six week single-blind clinical study was conducted to compare the effect of three dentifrices and a dental gel on the formation of dental plaque. On the criterion of their baseline plaque scores, male and female adult subjects were allocated to groups by restricted randomisation. The subjects used their assigned dentifrice twice a day and were examined for the presence of plaque after three and six weeks use. The results showed that the dental gel significantly reduced plaque when compared with the three dentifrices. There was no significant difference among the dentifrices with regard to plaque formation.
