ABSTRACT
Microbial populations colonizing the teeth and periodontal tissues are a major source of pathogens responsible for oral and dental infections including dental caries, gingivitis, periodontitis etc. Dental caries is a multifactor and infectious disease resulting dueto interaction of three different aspects like dietary sugar, susceptible tooth enamel and oral microbial colonization. Plaques from caries active sites have significantly higher proportion of Streptococcus mutans (principle acid producer) with pH levels of 5.0 or lower. Dental decay occurs when normal demineralization remineralization is disturbed. On the other hand the most common form of gingivitis is chronic or long standing plaque induced gingivitis while acute necrotizing ulcerative gingivitis is most aggressive, developing gingivitis is associated with increasing numbers of Actinomyces israeliwhereas gingivitis with bleeding is associated with A. viscosus and pigmented Bacteroides. Periodontitis is defined as loss of alveolar support to the tooth and can be differentiated microbiologically and clinically into adult, localised juvenile and pre-pubertal periodontitis. Various species of Bacteroides, Actinomyces, Fusobacterium etc. have been isolated from cases of active periodontitis. Thus wherever possible both aerobic and anaerobic culture should be performed and appropriate antibiotic therapy should be prescribed instead of empirical treatment.
