The immediate effectiveness of a multi-channeled oral irrigator in reducing dental plaque and oral malodor: A preliminary single-blind clinical trial

Tooth brushing typically removes approximately 42% to 60% of the initial dental plaque in healthy adults. A single cycle of MCOI use reduced plaque by approximately 25% and significantly lowered CH₃SH, a compound associated with periodontal disease. These findings suggest that the MCOI may serve as a useful adjunct to tooth brushing, particularly for individuals with limited motor skills, and could help reduce the risk of plaque-related oral diseases.
