The reconstruction of defects in the oral cavity after a large resection of intraoral cancer is relatively difficult because of its specific anatomical char acter and the exposure to infection from the oral bacterial flora. A forehead flap, or a deltopectoral flap, and a recently developped free flap with microvascular anastmosis has been the chosen method for the recon struction of defects in ...

Feline chronic gingivostomatitis (FCGS) is a chronic inflammatory disease of the oral cavity that causes severe pain and distress. There are currently no specific treatment methods available and little is known regarding its aetiology, although bacteria are thought to play a major role. The purpose of this study was to identify the oral bacterial flora in normal and diseased cats. Oral swabs we...

BACKGROUND Direct microscopy, anaerobic culture and DNA-DNA hybridization have previously demonstrated an association between microorganisms and osteoradionecrosis (ORN). The purpose of our study was to use culture independent molecular techniques to detect bacteria in necrotic bone lesions of the mandible after radiation therapy. DESIGN Bacterial DNA was extracted from eight deep medullar sp...

The dentogingival junction is of crucial importance in periodontal host defense both structurally and functionally. Oral bacteria exert a constant challenge to the host cells and tissues at the dentogingival junction. The host response is set up to eliminate the pathogens by the innate and adaptive defense mechanisms. In health, the commensal bacteria and the host defense mechanisms are in a dy...

the aim of this study was to assess the effects of nucleotide on intestinal microbiota of striped catfish, pangasianodon hypophthalmus . different levels of the nt (0, 0.25. 0.5, 0.75 and 1 % weight per weight, ww -1 ) were added to basal diet and then randomly allocated to triplicate groups of fish with average initial weight (1.52±0.11 g) for 10 weeks. at the end of the experiment, at least 1...

abstract introduction: diabetes increase salvia sugar and change its bacterial flora these changes destroy periodon-tal tissues. there are contravercies about affect of diabetes on periodontal tissues. in this study cpitn index that show intensity of periodontal damage was compared in insulin depended with healthy individual. methods and materials: in this study 132 cpitn index measured in 132 ...
