PERIODONTITIS, DISEASES, DENTAL CARIES, PLAQUE
Dental caries and periodontitis are biofilm-based behavior-mediated diseases, which could be largely prevented by relatively inexpensive measures such as home-based mechanical plaque removal, fluoride application, repeated individualized oral hygiene instructions with professional tooth cleaning, and risk factor control [The auto-cleaning device The purpose of this randomized-controlled and single-blinded cross-over study was to compare the cleansing efficacy of an auto-cleaning device with nylon bristles and flexible mouthpiece with that of uninstructed manual toothbrushing. The null hypothesis was that there would be no difference in plaque reduction between the two brushing methods in randomly selected probands.
