A review of anaerobic infections of the oral cavity in Egypt.

Abstract : Mocus membranes of the mouth and pharynx are often sterile at birth but may be contaminated by passage through the birth canal. Viridans steptococci become established and remain prominent for life. Other microorganisms such as gram-negative diplococci, diphtheroids, and occasionally lactobacilli are added afterwards. When teeth erupt, anaerobic conditions begin to exist in the gingival, crevicular, and interproximal areas. Anaerobic spirochetes, Bacteroides, Fusobacterium, some anaerobic vibrios, Actinomyces, and lactobacilli establish themselves. The oral cavity, as a matter of fact, represents a host environment possessing features that favor the location and growth of a great variety of microorganisms. Anaerobic infections of the oral cavity are described as: 1. Odontogenic infections. These involve the general inflammatory conditions affecting the periodontium, such as Gingivitis, Periodontitis. 2. Non-odontogenic infections - These are initiated by indirect intra or extra-oral sources. Actinomycosis and Abscesses are examples of non- odontogenetic infections. Reprints. (aw)
