The authors compare the periodontal status in 94 patients with moderate periodontitis over the course of treatment making use of various splint designs and without splints. The status of the periodontium was assessed basing on the time course of indexes. Administration of various multiple-modality treatment schemes resulted in improvement of the periodontal clinical status in all the patients, though the efficacy of the therapeutic measures was different. The improvement in respect of all the examined parameters was the most manifest only in the group of patients treated with fixed splints with parapulpal fixation or with those pickling-based.
