Purpose: The aim of this study was to assess the prevalence of aggressive periodontitis as well as tooth loss and periodontal attachment loss in subjects who visited the Department of Periodontology of Wonkwang University Daejeon Dental Hospital. Materials and Methods: A total of 3,284 patients with periodontitis from January 2010 to June 2012 were included in this study. We investigated prevalence of periodontitis, age, gender, and clinical parameters (probing depth, gingival recession, tooth loss, periodontal attachment loss), and radiographic examination was performed at the baseline. Results: Sixty-six (2.01%) patients showed clinical features of aggressive periodontitis. Periodontal attachment loss of the maxillary first molar was 0.85 mm, which was the highest. The average number of missing teeth was 1.35 per subject. Tooth mortality was the highest at the maxillary first molar and at the mandibular second molar. Conclusion: Within the limitations of this study, periodontal breakdown as evaluated by attachment loss was the most severe at the first molars of aggressive periodontitis patients. It is important to recognize clinical features of aggressive periodontitis for proper diagnosis and determination of treatment timing. Further studies are needed to obtain more precise epidemiologic information, including the prevalence of aggressive periodontitis in Koreans, and investigate the potential roles of risk factors and contributory factors, such as root abnormality, occlusion, family aggregation, gene polymorphism, and Herpes virus infections.
