Abstract
The purpose of this study was to assess the clinical outcomes of active periodontal therapy (APT) and supportive periodontal therapy (SPT) through loss of teeth in the Korean patients with aggressive periodontitis. The number of missing and residual teeth, probing pocket depth were examined in 33 patients diagnosed with aggressive periodontitis at the baseline and who had participated in APT and SPT for 3 years or more. A 20 and 3 teeth were lost during the APT and SPT, respectively. The mean tooth loss rate of 0.13 per patient and year. There was no signiffcant statistical difference in clinical improvement between the smoker and non-smoker groups. Within the limitation of this study, APT combined with supportive therapy could decrease the risk of tooth loss in patients suffering from aggressive periodontitis.
