Adjunctive dental therapy via tooth plaque reduction and gingivitis treatment by blue light-emitting diodes tooth brushing
Journal of Biomedical Optics
The efficacy of blue light-emitting toothbrushes (B-LETBs) (405 to 420 nm, power density 2 mW∕cm 2 ) for reduction of dental plaques and gingival inflammation has been evaluated. Microbiological study has shown the multifactor therapeutic action of the B-LETBs on oral pathological microflora: in addition to partial mechanical removal of bacteria, photodynamic action suppresses them up to 97.5%. In the pilot clinical studies, subjects with mild to moderate gingivitis have been randomly divideddoi:10.1117/1.jbo.20.12.128004 pmid:26720884 fatcat:jykd7psb3fethlqw66mwb6fvru
