The bactericidal effect of oral care using matching transformation system: A prospective clinical study

Abstract

AbstractAimMatching transformation system (MA‐T) is an on‐demand aqueous chlorine dioxide solution that realizes excellent safety with various antimicrobial activities even under abundant organic compound. By using MA‐T in human oral care, we examined its effectiveness against bacteria causing oral infections such as periodontal disease and dental caries.Materials and MethodsThe participants of the 75th Annual Meeting of the Japanese Stomatological Society held on May 13 and 14, 2021, were enrolled in this study. Saliva samples were collected on the first day after normal oral care and on the second day after oral care with MA‐T. The total number of bacteria and the numbers of Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Streptococcus mutans, and Candida albicans were compared for the two samples on Days 1 and 2.ResultsTwenty‐two subjects met the study criteria. The total bacterial count and the number of T. forsythia on Day 2 were significantly lower than those on Day 1 (p = 0.000177 and p = 0.0186, respectively). The numbers of T. denticola and S. mutans tended to decrease, although not significantly (p = 0.100 and p = 0.251, respectively). Statistical analysis was not performed for P. gingivalis and C. albicans because of sample size.ConclusionMA‐T is putatively effective for oral hygiene. MA‐T oral care reduces bacteria that cause periodontal disease and dental caries compared with regular oral care. The results of this study suggest that MA‐T, a new disinfectant, can be applied to oral care and may reduce periodontal disease, dental caries, and other oral infections.
