Use of mouthwash improves oral health more than toothbrushing alone
CHICAGO, Ill., USA: The findings of a new study suggest that using a germ-killing mouthwash in addition to regular toothbrushing provides greater oral health benefits than toothbrushing alone. Study participants who rinsed their mouth twice a day reduced plaque and gingivitis significantly.
The study was conducted among 139 U.S. adults diagnosed with mild to moderate plaque and gingivitis, who were divided into two groups. While members of the first group brushed their teeth and rinsed with an antimicrobial mouthwash twice a day, members of the second group used a placebo mouthwash.
After six months, the researchers observed that participants in the first group had reduced their dental plaque by up to 26.3 percent. In addition, the study found that almost 100 percent of the participants using the antimicrobial mouthwash showed a reduction in gingivitis, compared with only 30 percent in the placebo group. Overall, members of the antimicrobial mouthwash group had a 20.4 percent reduction in gingivitis, said Dr. Janice Pliszczak, representative of the Academy of General Dentistry.
According to the study's authors, mouthwash can reach nearly 100 percent of the mouth's surface, while toothbrushing affects only 25 percent. By using a germ-killing mouth rinse twice a day in addition to one's daily brushing routine, a person can effectively target oral bacteria usually left behind, they concluded.
The study was published in the January/February issue of General Dentistry, the journal of the Academy of General Dentistry.
