Malattia parodontale e malattia cardiovascolare: correlazione o semplice coincidenza? Revisione della letteratura
2007
The present paper reviews relationship between chronic periodontitis and cardiovascular diseases. Original papers on this subject, published in English in the period between 2001 and the first semester 2006, were located in the MEDLINE/PubMed database. Additional studies were obtained by searching reference lists of previously published papers. Periodontal infection provides a chronic reservoir of inflammatory mediators and cytokines, lipopolysaccharide, which contribute to the formation of atheroma. Moreover, periodontal pathogens can penetrate the epithelial barrier of the periodontal tissues and reach the blood stream, carrying out a local atherogenic activity. Some studies indicated tha…
Occurrence of invading bacteria in radicular dentin of periodontally diseased teeth: Microbiological findings
1997
Bacterial invasion in roots of periodontally diseased teeth, which has been recently documented using cultural and microscopic techniques, may be important in the pathogenesis of periodontal disease. The purpose of this investigation was to determine the occurrence and the species of invading bacteria in radicular dentin of periodontally diseased teeth. Samples were taken from the middle layer of radicular dentin of 26 periodontally diseased teeth. 14 healthy teeth were used as controls. Dentin samples were cultured anaerobically. The chosen methodology allowed the determination of the numbers of bacteria present in both deeper and outer part of dentinal tubules, and the bacterial concentra…
