Zusammenfassung:The purpose of the present study was to evaluate longitudinally the effects of orthodontic and periodontic therapy on periodontal health in ten patients with the malposed anteriors and high gingival inflammation. Periodontal conditions were evaluated according to the amount of gingival crevicular fluid (GCF), Gingival Index, Plaque Index, Gingival Bleeding Index and pocket depth before, during and after treatment. GCF was used for assay of protein, collagenase, acid and alkaline phosphatase activities. Number of GCF leucocyte was also evaluated and the following results were obtained. GCF amount measured by Periotron in anterior incisors at first visit was 1, 147±412 (unit, Mean±S. D.). After initial therapy and in maintenance phase the amount of GCF decreased 328+97 and 256±133. Two forms of collagenase, active and latent forms were found in GCF. Total collagenase activity before therapy was 43, 457±22, 934 (cpm, Mean±S. D.) and decreased 13, 302+6, 125 and 18, 273±9, 155 after initial therapy and in maintenance phase. Ratio of latent/active collagenase activity was 1.39 before therapy, 1.87 after initial therapy and 1.92 in maintenance care. Changes in total collagenase activity and latent/active collagenase might be an indicator of ortho-perio therapy in children with malposed anteriors. Acid and alkaline phosphatase activities were also decreased 90% and 82% smaller than initial examination. Number of GCF leucocyte decreased 70% smaller than initial examination. Gingival index decreased from 1.55±0.68 to 0.42±0.64 and Plaque Index also significantly decreased from 1.53±0.65 to 0.38±0.53 in maintenance phase. Gingival Bleeding Index decreased from 82.5±10.8 (%) to 13.6±11.4 (%). Pocket depth decreased from 2.29±1.23 (mm) to 1.72±0.76. (mm). In conclusion, it was revealed that long term maintenance care of periodontal tissue was prerequisite for patients in orthodontic treatment and regeneration of tissue would be expected by co-operative orthodontic and periodontic therapy.
