Resumo IPEN-doc 12991 Comparative study between photodynamic therapy and chemical solution on bacterial reduction in root canals2004 - NUNEZ, S.C.; GOMES, L.; GARCEZ, A.S.; LAGE-MARQUES, J.L.One of the major medical problems facing mankind in the next century will be the resistance of many pathogenic microbes to existing antibiotics. Oral bacteria can easily reach other body sites and also spread to other individuals. Therefore, antibiotic-resistant oral bacteria have the opportunity for rapid dissemination through the community and to transfer their resistance genes to other bacterial species. Photodynamic therapy involves the use of light-activated drugs which may offer an alternative approach to the use of traditional antimicrobial agents. The purpose of this study was to evaluate bacterial reduction in infected root canal. Thirty teeth with their root canals prepared were contaminated with Enterococcus faecalis. Control group was untreated. Chemical group was treated with sodium hypochlorite for 30 minutes and in the laser group, a photosensitizer paste was placed and maintained in the root canals for 5 minutes and irradiated with a diode laser, output power 10 mW and l= 685nm for 3 minutes. The bacterial reduction was significantly higher for laser group when compared to chemical and control groups. These results indicate photodynamic therapy as an effective method to kill E. faecalis.Resumo IPEN-doc 18622 Surgical endodontic treatment associated with photodynamic antimicrobial therapy2012 - BAPTISTA, A.; GARCEZ, A.S.; NUNEZ, S.C.; FREGNANI, E.; SELLERA, D.P.; RIBEIRO, M.S.; SUZUKI, H.Resumo IPEN-doc 18620 Antimicrobial photodynamic therapy in periodontics: cases report2012 - NUNEZ, S.C.; GARCEZ, A.S.; RIBEIRO, M.S.Artigo IPEN-doc 18741 Modelo de estudo in vitro da distribuição da luz em infecções de biofilme de Candida albicans2012 - NUNEZ, S.C.; SABINO, C.P.; GARCEZ, A.S.; RIBEIRO, M.S.Resumo IPEN-doc 15944 Efeito da terapia fotodinâmica na matriz extracelular de bactériaGram negativa avaliado por microscopia de força atômica2010 - GARCEZ, A.S.; NUNEZ, S.C.; RIBEIRO, M.S.; MIYAKAWA, W.Resumo IPEN-doc 14807 Antimicrobial effects of photodynamic therapy on patients with necrotic pulps anmd periapical lesion2007 - GARCEZ, A.S.; NUNEZ, S.C.; ZEZELL, D.M.; HAMBLIN, M.R.; RIBEIRO, M.S.Artigo IPEN-doc 19635 Effects of photodynamic therapy on gram-positive and gram-negative bacterial biofilms by bioluminescence imaging and scanning electron microscopic analysis2013 - GARCEZ, AGUINALDO S.; NUNEZ, SILVIA C.; AZAMBUJA, NILTON; FREGNANI, EDUARDO R.; RODRIGUEZ, HELENA M.H.; HAMBLIN, MICHAEL R.; SUZUKI, HIDEO; RIBEIRO, MARTHA S.Artigo IPEN-doc 12324 Photonic real-time monitoring of bacterial reduction in root canals by genetically engineered bacteria after chemomechanical endodontic therapy2007 - GARCEZ, AGUINALDO S.; NUNEZ, SILVIA C.; MARQUES, JOSÉ L.L.; HAMBLIN, MICHAEL R.; RIBEIRO, MARTHA S.Artigo IPEN-doc 11786 Efficiency of NaOCl and laser-assisted photosensitization on the reduction of enterococcus faecalis in vitro2006 - GARCEZ, AGUINALDO S.; NUNEZ, SILVIA C.; LAGE MARQUES, JOSE L.; JORGE, ANTONIO O.C.; RIBEIRO, MARTHA S.Artigo IPEN-doc 11902 Effects of low-power red laser on dentine-pulp interface after cavity preparation.
