oral infections

Just thought we would pass along this wonderful web site regarding the role of oral infections in systemic disease from the American Academy of Periodontology of all places. The site discusses the contribution of bacteria involved in periodontal disease with the development of heart disease, stroke, pre-term, low birth weight infants, diabetes, respiratory diseases, and osteoporosis (see http://www.perio.org/consumer/mbc.top2.htm).One has to ask, if the bacteria involved in periodontal disease can contribute to all these systemic diseases, what about the bacteria residing in the dentinal tubules of avital, endodontically treated (root canal) teeth. As Dr. Walter Loesche and colleagues so eloquently pointed out, most, if not all, periodontally diseased teeth harbor bacteria within the dentinal tubules and these bacteria constitute a "pathogenic reservoir" form which reinfection of the periodontal pocket can occur (see references below). If vital, but periodontally diseased teeth can harbor such pathogens, what about dead root canal teeth. Surely, any dead tissue allowed to remain in an environment such as the mouth, with its favorable conditions for bacterial growth, is bound to become infected with bacteria regardless of how it is embalmed.Bacterial invasion in root cementum and radicular dentin of periodontally diseased teeth in humans.
