Effect of toothpaste containing emulsifier 30 and sodium lauryl sulfate surfactant on the integrity of oral epithelium

PURPOSE: To investigate the effect of toothpaste containing emulsifier 30 and sodium lauryl sulfate surfactant on the integrity of oral epithelium. METHODS: Sixty individuals equally divided into 2 groups by random number table methods. Group A received toothpaste containing emulsifier 30, while group B received fluoride toothpaste containing sodium lauryl sulfate (SLS) surfactant. The exfoliation of oral soft tissue was evaluated before, 30 minutes and 4 days after the test. The fluoride concentration in plaque and saliva was compared between the two groups. The data were processed with SPSS 22.0 software package. RESULTS: The scores of oral soft tissue exfoliation at 30 min and 4 d after the test were increased significantly (P<0.05). The scores of subgingival, supragingival, oral apex and oral soft tissue exfoliation of group A at 30 min after using the paste were significantly lower than those 4 days after using the paste(P<0.05), while no significant change was observed in the score of oral soft tissue exfoliation at the dorsal tongue(P>0.05). The total scores of subgingival, supragingival, dorsal tongue, ventral tongue and oral soft tissue exfoliation in group B 30 min after using the paste were significantly higher than those at 4 d after use, and the score of oral soft tissue exfoliation at oral apex was significantly lower than that at 4 d after use (P<0.05).The total scores of subgingival, supragingival, dorsal tongue, ventral tongue and oral soft tissue exfoliation in group B at 30 min after using the paste were significantly higher than those of group A, while the score of oral soft tissue exfoliation at oral apex was significantly lower than that of group A(P<0.05).The total scores of subgingival, supragingival, ventral tongue and oral soft tissue exfoliation in group B at 4 d after using the paste were significantly higher than those of group A(P<0.05). The scores of oral soft tissue exfoliation at oral apex and dorsal tongue at 4 d after use had no significant difference between the two groups (P>0.05). The fluoride concentration in plaque and saliva was increased significantly in both groups after test(P<0.05). CONCLUSIONS: Both fluoride toothpaste containing emulsifier 30 and SLS surfactant cause a certain degree of oral soft tissue exfoliation. In comparison, fluoride toothpaste containing emulsifier 30 has less oral soft tissue damage; moreover, the two fluoride toothpastes can effectively inhibit acid production of plaque bacteria and prevent occurrence of caries.
