Introduction: Many infections of the oral cavity and adjacent structures involve anaerobic bacteria. Most infections involve multiple anaerobes and in many instances facultative organisms. Present study was conducted regarding to clinical aspects and complications of anaerobic bacterial infections in oral cavity.Materials and Methods: 72 Specimens were taken from oral cavity infections. Routine culture techniques and strict anaerobic techniques were used for isolation and identification of aerobic, facultative and obligatory anaerobic bacteria respectively.Results: Cultures of all specimens were positive. Mono- bacterial and poly bacterial infections were repored in 1/3 and 2/3 of specimens, respectively. More than 65% of isolated organisms, were obligatory anaerobic belonging to the Peptostreptococcus, Prevotella, Fusobacterium, Porphyromonas and Bacteriodes  as well as facultative and aerobic species include Streptococcus, Staphylococcus , interobacteriacea and Actinomcs Israelii are also obtained.Conclusion: Many infections of the oral cavity and adjacent structures involve obligatory anaerobic bacteria. Regarding to results of present study, under the anaerobic atmospheric system, obligatory anaerobic bacteria were isolated and identified from clinical specimens of oral cavity infections, especially abscesses.
