title: Effect of supervised use of an alum mouthrinse on dental caries incidence in caries-susceptible children: a pilot study.
abstract: Aluminum salts have demonstrated anticaries activity in a number of laboratory and animal studies. The aim of this double-blind, pilot, clinical trial was to evaluate the effect of an alum (Al) mouthrinse on dental caries formation both by itself and in combination with an ADA-approved sodium fluoride (F) dentifrice. A total of 260 caries-prone children residing in a low-F area were preselected for the study and scored independently for caries by two experienced examiners. After using gender, age, and initial DMFT(S) scores for baseline stratification, the subjects were assigned to one of three treatment regimens: (1) placebo mouthrinse and F dentifrice, (2) Al mouthrinse and placebo dentifrice, and (3) Al mouthrinse and F dentifrice. The alum mouthrinse contained 500 ppm Al and the sodium fluoride dentifrice contained 1100 ppm F. Rinsing was supervised at school on weekdays for 30 sec/day, while the dentifrices were used ad libitum at home. Subjects were reexamined for caries and oral health after six and twelve months. Both examiners found that children who used Al mouthrinse, in conjunction with either placebo or F dentifrices, had lower caries incidence than those who used placebo mouthrinse/F dentifrice combination; but the differences were statistically significant for only one of the examiners. No evidence of deleterious effects to the oral tissues was observed. The results of this pilot clinical trial demonstrated that daily supervised use of an alum mouthrinse inhibited caries development in decay-prone children at least as effectively as a F dentifrice.
