Oral biofilms or dental plaques are one of the major etiological factors for diverse oral diseases, such as gingival inflammation and dental caries. Formation of the biofilm begins 1 h after oral rinsing. Then it is assumed to mature within approximately 72 h, and the dynamics and composition could be affected by the diet and immunity of the hostBy using conventional toothbrushing with cleansing agents, pathogens in the biofilm can be significantly reduced by disrupting the integrity of the pathological organism network while maintaining commensal bacteria. Mechanical toothbrushing in any form is considered the gold standard for removing dental plaqueThe disadvantages of these devices are that they must be placed at the exact location where irrigation is required, and they have the risk of aspiration due to the lack of suction function. Aspiration pneumonia is fatal in disabled and elderly peopleThis study aimed to evaluate the effectiveness of a new oral hygiene device (MCOI) on periodontal health. By performing 16s rRNA amplicon sequencing and shotgun metagenomic sequencing, changes in the oral microbiota were also investigated.
