Abstract
Two molars having furcation grade II involvements were selected from each of six patients with periodontal diseases. One molar received a local application of tetracycline immobilized cross-liked collagen film four times at one-week intervals (TC film-treated group) and the other received no treatment (non-treated group). The clinical and microbiological effects were, as follows, 1. Throughout the experimental period, no significant differences in pocket depth, attachment level, bleeding on pocket probing, periotron unit, gingival index and plaque index were noted between the TC film-treated group and the non-treated group. 2. One week after TC-film application, the treated group showed significant decreases in the density of microorganisms and the proportion of spirochetes compared with the non-treated group. The results revealed the insufficient effectiveness of the local application of TC film by itself for the treatment of teeth having furcation grade II involvements.
