主 题:Photodynamic therapy periodontitis toluidine blue O endogenous photosensitizer survival rate
摘 要:Photodynamic therapy(PDT)has been commonly used in treating many diseases,such as cancer and infectious *** investigated the different effects of PDT on three main pathogenic bacteria of periodontitis-Prevotella melaninogenica(P.m.),Porphyromonas gingitvalis(P.g.)and Aggregatibacter actinomycetercomitans(A.a-).The portable red light-ermitting diode(LED)phototherapy device was used to assess the exogenous PDT effects with different light doses and photosensitizer concentrations(Toluidine blue O,TBO).The portable blue LED phototherapy device was used to assess the endogenous PDT effects with the use of endogenous photosensit izers(porphyrin)under dfferent light *** found out that both exogenous and endogenous PDT were able to restrict the growth of all the three bacteria ***,the optimal PDT conditions for these bacteria were obtained through this in vitro screening and could guide the clinical PDT on periodontitis.
