Abstract: Objective: To investigate the visits of patients with aggressive periodontitis in Nanjing. Methods: The electronic medical records and panoramic films of patients with aggressive periodontitis diagnosed in the Department of Periodontology, Nanjing Stomatological Hospital, Medical School of Nanjing University from January 1, 2013 to December 31, 2018 were collected through the electronic medical record system and PACS image analysis system. According to the medical records, the causes for visit, diagnostic rate, rate of tooth loss, treatment, and alveolar bone destruction of patients with aggressive periodontitis under 35 years old were statistically analyzed. Results: The main cause for visit of the patients with aggressive periodontitis was tooth loosening. The overall diagnostic rate within 6 years was 1.7%. Tooth loss accounted for 30.7% of the patients with aggressive periodontitis. 81.31% patients received periodontal treatment. The proportions of surgery and maintenance were 13.2% and 30.8%, respectively. Conclusion: Aggressive periodontitis in Nanjing presents a high incidence, a high rate of tooth loss, and great harm. However, the proportion of patients receiving systematic treatment is low. Therefore, popular science propaganda and education should be strengthened so as to raise patients’ awareness of prevention.
