Journal ArticleDOI
Use of hand held photopolymerizer to photoinactivate Streptococcus mutans.
Tony De Paiva Paulino,K.F. Ribeiro,Geraldo Thedei,Antonio Claudio Tedesco,Pietro Ciancaglini +4 more
TL;DR: The photoactivation of Rose Bengal, using the HHP, inactivated the bacteria without affecting the fibroblast viability and it was observed that the light is not toxic and in the dark Rose Bengal is toxic to the cells tested only at concentrations above 2.5 microM.
Journal ArticleDOI
Photodynamic therapy in planktonic and biofilm cultures of Aggregatibacter actinomycetemcomitans.
Rosangela de Carvalho Goulart,Maytê Bolean,Tony De Paiva Paulino,Geraldo Thedei,Sérgio Luis Scombatti de Souza,Antonio Claudio Tedesco,Pietro Ciancaglini +6 more
TL;DR: Photodynamic therapy-generated ROS inactivates A. actinomycetemcomitans both in planktonic and biofilm cultures, even in small concentrations of the photosensitizing agent, and it does not cause damage to fibroblast cells under the same conditions.
Journal ArticleDOI
Comparative study of methylene blue and erythrosine dyes employed in photodynamic therapy for inactivation of planktonic and biofilm-cultivated Aggregatibacter actinomycetemcomitans.
Rosangela de Carvalho Goulart,Geraldo Thedei,Sérgio Luis Scombatti de Souza,Antonio Claudio Tedesco,Pietro Ciancaglini +4 more
TL;DR: Results show that ERY is more efficient at killing bacterial cells of A. actinomycetemcomitans in planktonic and biofilm culture compared with MB, suggesting that PDT using MB or ERY as a photosensitizing agent and odontologic resin photopolymerizer as a light source could be an efficient option for pocket decontamination in aggressive periodontal disease.
Journal ArticleDOI
Local delivery of EGF-liposome mediated bone modeling in orthodontic tooth movement by increasing RANKL expression.
José B. Alves,Cynthia Lopes Ferreira,Aline Isabel Ferreira Martins,Gerluza Aparecida Borges Silva,Guilherme Dias Alves,Tony De Paiva Paulino,Pietro Ciancaglini,Geraldo Thedei,Marcelo Henrique Napimoga +8 more
TL;DR: The EGF-liposome administration showed an increased tooth movement and osteoclast numbers compared to controls and this was correlated with intense RANKL expression, and both osteoblasts and osteoclasts expressed EGFR.
Journal ArticleDOI
Lipid composition-dependent incorporation of multiple membrane proteins into liposomes.
Katia Regina Perez Daghastanli,Rinaldo Bueno Ferreira,Geraldo Thedei,Bruno Maggio,Pietro Ciancaglini +4 more
TL;DR: Membrane proteins from bacteria Pasteurella multocida were used as a model for studying its incorporation into liposomes and the highest incorporation of multiple proteins was found with dipalmitoylphosphatidylcholine (DPPC), reaching a yield of 93% compared to the lower relative amounts incorporated in proteoliposomes of the other lipids.
