This study used 3 kinds of experimental toothpaste prepared with different contents of SLS, i.e. A (0%), B (1.1%), C (2.2%). These 150 subjects were subdivided again into three groups. After 4 weeks application of the three kinds of toothpaste, it was found that there were differences in dental plaque test (PHP) among the 3 groups; that is; a higher SLS content was associated with a lower PHP index. In addition, it was found that all 3 groups showed a reduction in simplified oral hygiene index (OHI-S). After 4 weeks application of the three groups of toothpaste, it was found that a higher SLS content was associated with a lower salivary flow, but there was no significant variation in salivary mucosity and pH. Further, it was found that SLS was negatively correlated with salivary flow, which supports the theory that SLS may induce xerostomia.
