Antimicrobial photodynamic therapy alone or in combination with antibiotic local administration against biofilms of Fusobacterium nucleatum and Porphyromonas gingivalis.

Journal of photochemistry and photobiology. B, Biology

Tavares LJ, de Avila ED, Klein MI, Panariello BHD, Spolidório DMP, Pavarina AC.

Antimicrobial photodynamic therapy (aPDT) kills several planktonic pathogens. However, the susceptibility of biofilm-derived anaerobic bacteria to aPDT is poorly characterized. Here, we evaluated the effect of Photodithazine (PDZ)-mediated aPDT on Fusobacterium nucleatum and Porphyromonas gingivalis biofilms. In addition, aPDT...

Microbial etiology for anti-osteoclastic drug-related osteonecrosis of the jaw (ARONJ) was suggested. This study investigates any link between bacteria colonizing ARONJ sites and other oral cavity sites. Microbiota samples of 10 ARONJ patients were collected from the exposed bone,...

[Pelvic actinomycosis: a misleading picture].

Pelvic actinomycosis is a rare chronic suppurative granulomatous disease associated with an intrauterine contraceptive device. Next pelvic organs can be affected but also more distant organs, to lead to different clinical situations. The diagnosis is therefore often difficult. We...

Transmission of periodontopathic bacteria from natural teeth to implants.

PURPOSE: Prevention of peri-implantitis is essential for the success of implant rehabilitation. Infection by periodontopathic bacteria is a major cause of peri-implantitis. The aim of the present study was to identify the source of peri-implant colonization by periodontopathic bacteria.MATERIALS...

INTRODUCTION: This purpose of this study was to document and investigate changes in periodontal pathogen levels before, during, and after orthodontic treatment in adolescents.METHODS: DNA gene probe analysis was used to quantify the levels of 8 periodontal pathogens before,...

Bone microbial contamination influences autogenous grafting in sinus augmentation.

Journal of periodontology

Verdugo F, Castillo A, Moragues MD, Pontón J.

J Periodontol. 2009 Aug;80(8):1355-64. doi: 10.1902/jop.2009.090113.

BACKGROUND: The oral occurrence of putative microbial pathogens in humans has been documented in health and disease. The presence of periodontopathogens in patients with a history of periodontal disease may have a negative impact on bone regeneration. This investigation...
