简要总结
Arginine is an adjunct to oral health care that has the potential to modulate the composition and activity of the microbial community of dental biofilms towards a health-related status without harmful effects for the resident oral microbiota. The aim of the study is to investigate the effects of arginine treatment compared to placebo on the composition, metabolism, and microarchitecture of biofilms grown in situ in the oral cavity of caries-active participants.
