The Modified Bass brushing technique is recommended by dental professionals and has been validated by two studies to be effective for plaque biofilm removal from the gingival third of the teeth.
10 The microbial components of the plaque biofilm can also affect the risk of having periodontal disease.
Test subjects using a Water Flosser in conjunction with a manual toothbrush had up to 29% better reduction in plaque biofilm than people who used a manual toothbrush and string floss.
For the study, teeth from patients with extensive gum disease and plaque build-up were extracted, and then processed to accelerate additional plaque biofilm growth.
In a study on permeability of oral microorganisms and dental plaque, both gram +ve and gram -ve such as Porphyromonas endodontalis and Porphyromonas gingivalis were more sensitive to Ozonated water than gram +ve oral Streptococci and Candida albicans in pure culture and Ozonated water was proved to have bactericidal activity against bacteria in plaque biofilm.
2) Dental plaque biofilm is a known etiological factor that causes oral diseases such as dental caries, (3) gingivitis, (4) and periodontitis.
Undisturbed plaque biofilm can cause gingival inflammation and bleeding and increase the risk for and progression of periodontal disease.
With this in mind it is reasonable to hypothesise that the slow release from the device would increase F concentrations in saliva and possibly plaque or at least reduce loss of accumulated fluoride from plaque biofilm layers.
The chemical action of stabilized stannous fluoride in Crest Pro-Health Toothpaste inhibits the metabolic activity of destructive bacteria while cetylpyridinium chloride (CPC) in Crest Pro-Health Rinse inhibits the regrowth of plaque biofilm, Proctor and Gamble reports.
Unlike conventional mechanical polishing (handpiece with rubber-cup and prophylaxis paste) used to polish teeth, the air polisher uses a light handpiece similar to an ultrasonic scaler to generate a slurry of pressurized air, abrasive powder and water to remove plaque biofilm and stains (Figures 1, 2).
1) Hence, periodontal therapeutic modalities must aim at conversion of the pathogenic plaque biofilm to a non-pathogenic harmonious environment to optimize and balance periodontal health.
Of critical importance to whitening success is thorough pre-whitening instrumentation to remove extrinsic stain, calculus and plaque biofilm.
