Abstract:
Objective To understand the distribution of anaerobes in gingivitis infection, and anaerobes sensitivity to ? lastams Methods 44 specimens were taken from the gingival crevicular fluid of gingivitis. The anaerobic bacteria were cultured and identified Minimal inhibitory concentrations (MIC) were measured by using agar dilution method Results Among all samples, the isolation of anaerobes was 100%, the isolation of P.melaninogenica was 86.4%, P.intermedia was 56.8%, B.forsythus was 52.3%, P.gingivalis was 65.9%, F.mucleatum was 63.6%, P.micros was 52.3%, Actinomyces ssp was 38.6% and Capnocytophaga ssp was 9.1% respectively. The anaerobes are sensitive to ? lastams. Conclusion In gingival crevicular fluid, the infection rates of P.melaninogenica, P.intermedia, B.forsythus, P.gingivalis, F.mucleatum, P.micros, and Actinomyces ssp were significantly higher than those of the other anaerobes. ? lastams can be used for the treatment of anaerobes infected gingivitis.
