Effect of a single-use toothbrush on plaque microflora
Department of Microbiology, Yenepoya Medical College, Mangalore, Karnataka, India
Aim: To study and compare the microbial flora of dental plaque after the use of a self-contaminated toothbrush and that of a single-use toothbrush.
Materials and Methods: The study group included 40 young volunteers from Yenepoya Dental College, who were free from any systemic or oral disease. In these subjects, plaque samples were collected after 1 month use of a self-contaminated toothbrush. Each subject was given a set of 30 new toothbrushes and a toothpaste tube and instructed to use one toothbrush everyday and discard it after use. The plaque samples were collected on a weekly interval and cultured on Mitis Salivarius agar. The colonies were identified and speciated and their count was recorded.
Results: Streptococcus mitis, S. mutans, S. sanguis, S. milleri and Candida were recovered from the samples. A highly significant decrease in their numbers was found after the use of a single-use toothbrush (P value 0.001).
Conclusions : As a contaminated toothbrush can reintroduce microorganisms into the oral cavity, it may be a sound practice to change the toothbrush as frequently as possible.
