ABSTRACT

Objective: To identify aerobic and anaerobic microbiota in pericoronitis of the third molar in order to determine the most appropriate antibiotic therapy and enable the right treatment of the patient.
Study Format: This descriptive cross-sectional study included 46 patients of both sexes with subacute pericoronitis of the third molars, all of whom had given their informed consent; all patients were over 14 years of age and none had received any antibiotic therapy in the previous three months nor used any kind of mouthwash in the 3 weeks prior to their recruitment. The patients were submitted to a systemic, clinical, and radiographic assessment. Samples were taken of microbiota present in the pericoronitis, the microorganisms collected then being cultivated in order for them to be identified and classified. Descriptive statistics and frequency tables were used to analyze the results.
Results: Third molar 38 showed the highest frequency of pericoronitis, followed by third molar 48. Streptococcus viridans, Streptococcus milleri and coagulase-negative staphylococcus were the main microorganisms found in the aerobic microbiota. In the anaerobic microbiota, Peptoestreptococcus SP and Bacteroides SP were the more frequent.
Conclusions: Pericoronitis in Mexicans occurs most often in young adult women, the lower-left third molar being that most commonly associated with this condition. The most common aerobic and anaerobic microbiota consist of cocci and Gram-negative bacilli. However, the prevalence of Streptococcus viridans and Streptococcus milleri is associated with purulent abscesses. Amoxicillin/clavulanic acid or clindamycin were effective during the remission of the subacute pericoronitis infection.
