Effect of Sodium Lauryl Sulfate on Recurrent Aphthous Stomatitis

Summary

Sodium lauryl sulfate (SLS) is an anionic detergent that has been used as the major or sole surfactant in most dentifrices. But it is known to local irritating factor to oral mucosa and skin and results in many side effects. This study was to compare the effects of SLS-free dentifrice and SLS-containing dentifrice in patients with recurrent aphthous stomatitis (RAS).

Conditions

• Recurrent Aphthous Stomatitis

Interventions

OTHER

sodium lauryl sulfate

The subjects were divided into three groups, each of which comprised 30 randomly assigned subjects: group I used SLS-free(a commercially available SLS-free dentifrice(Wiconi® dentifrice) and SLS-A (a dentifrice containing 1.5%; Wiconi® dentifrice + 1.5% SLS). The subjects used one of the two assigned dentifrices for 8 weeks, and then the other for the following 8 weeks. The order of the dentifrices used was selected at random, and there was a 2-week washout period between the two phases, during which the subject used the same dentifrice as they used before participating in this study. The subjects were asked to brush their teeth using their usual toothbrushing method with the dentifrice and toothbrush supplied.
