Progression of periodontal disease in patients with mild to moderate adult periodontitis.
The aim of the present study was to determine the progression rate of periodontal disease in patients treated for localized or generalized mild to moderate adult periodontitis. 52 patients with a mean age of 53.7 years (S.D. 12.6 years) were instructed in optimal home care procedures and exposed to initial periodontal therapy, before reconstructive therapy was initiated. Following completion of the prosthetic procedures, supportive therapy was offered to a limited extent and maintenance visits were irregularly scheduled corresponding to traditional dental care. Clinical periodontal parameters from 4 sites per tooth were assessed at the initial examination, at the time of reevaluation after initial therapy and at the re-examination after 8-years. Full sets of intraoral radiographs from the initial and the 8-year re-examination were analyzed with respect to changes in the radiographic alveolar bone height as a % of the total tooth length. As the result of the home care instructions, the mean plaque index (plaque control record) amounted to 21% at the end of initial periodontal therapy. 8 years later, the re-examination revealed a mean plaque index of 49% and a mean gingival bleeding index of 24%. At the initial examination, the 52 patients presented with an average of 18.7 teeth. During treatment, 26 teeth were sacrificed and 19 teeth were lost over the 8 years of supportive therapy. Bicuspids were the most frequent teeth to be lost over the observation period. As a result of initial therapy, the mean pocket probing depths decreased significantly. However, after 8 years, only minor differences were found when compared to the initial examination.(ABSTRACT TRUNCATED AT 250 WORDS)
