• COZING-USBO3-3 can be effectively used for the following indications:
• antibacterial properties,controlling harmful bacteria in periodontal disease
• combating harmful bacteria associated with receding gums
• promoting overall Oral health
• helps eliminate stains and discoloration
• enhancing tissue repair
• Bad breath

 

 

COZING-USBO3-3 takes deep cleaning to a new level with its advanced blue light therapy technology. Blue light travels easily to hard-to-reach areas, penetrating between teeth and under the gum line to target harmful bacteria - the very source of gingivitis, periodontitis, inflammation, bleeding, and recession.
Simultaneously,Blue light promoting gum health by enhancing tissue repair and controlling harmful bacteria in periodontal disease, stimulating circulation and cellular renewal - a benefit proven by NASA research. This powerful combination promotes a balanced Oral microbiome and optimizes gum health, helping to prevent gum disease and ensure long-lasting freshness.

Methods

Varieties of Aggregatibacter actinomycetemcomitans, Fusobacterium nucleatum, and Porphyromonas gingivalis, in either free-floating or biofilm configurations, underwent illumination with visible light spanning wavelengths of 400.520 nm. A dental illumination device emitting at a power density of 500 mW/cm2 served as the light source. Each specimen endured exposure durations of 15, 30, 60, 90, or 120 seconds against individual bacterial strains in both free-floating or biofilm setups. Visualization of live/dead bacterial cell distribution within biofilms was achieved through confocal scanning laser microscopy (CSLM). Post-illumination, bacterial eradication rates were computed based on colony forming unit (CFU) enumerations.



Results

CLSM imagery captured from biofilms exhibited a blend of deceased and viable bacterial cells, permeating to depths of 30-45 µm. Notable variances in the live-to-dead bacterial cell ratio were discerned within P. gingivalis biofilms contingent upon light exposure durations. In the free-floating state, nearly all bacteria succumbed to 60 seconds of light exposure for F. nucleatum (99.1%) and 15 seconds for P. gingivalis (100%). Conversely, within biofilm configurations, only the CFU of P. gingivalis exhibited a diminishing trend with escalating light exposure durations, showcasing reduced phototoxicity efficacy against P. gingivalis as a biofilm compared to its free-floating counterpart.



Conclusions

Utilizing blue light exposure via a dental light curing apparatus proves efficacious in diminishing periodontal pathogens in their free-floating state. It is advisable to complement this approach with an external photosensitizer and subject pathogens to visible light exposure for clinical antimicrobial periodontal interventions.
