Oral Microbial Flora in Bulgarian Adolescents with Moderate Plaque-induced Gingivitis.

INTRODUCTION: In children and adolescents, the most common periodontal disease is the plaque-induced gingivitis. AIM: The aim of this study was to reveal the bacterial species associated with supragingival plaque of Bulgarian adolescents diagnosed with plaque-induced gingivitis. MATERIALS AND METHODS: Supragingival plaque samples from 70 healthy subjects with moderate plaque-induced gingivitis (37 females and 33 males), aged 12-18 years, were obtained and examined microbiologically. RESULTS: A total of 224 microorganisms were isolated. Gram-negative bacteria were predominant compared to Gram-positive [132 (59%) vs. 92 (41%). CONCLUSION: The most frequently isolated microbiota in our study is part of the normal oral bacterial flora. The presence of anaerobes such as.
