A comparative study of clinical effects following treatment of class II furcations using allograft and PR with and without bioabsorbable membrane / 대한치주과학회지

ABSTRACT

The present study evaluated of regeneration effect of platelet rich plasma on the treatment of classII furcation involvement, with allograft in humans. The control was treated without bioabsorbable membrane, and the test was treated with bioabsorbable membrane. Pocket depth, clinical attachment level, and gingival recession were measured at baseline, postoperative 3, 6months. Both groups were statistically analyzed by Wilcoxon signed Ranks Test & Mann-whitney Test using SPSS program (5% significance level). The results were as follows 1. The change of pocket depth and clinical attachment level in both groups was decreased significantly at 3, 6months. (p<0.05) 2. The change of gingival recession in both groups was increased significantly at 3, 6months than at baseline. (p<0.05) 3. The change of pocket depth and clinical attachment level in both groups was increased significantly at 3, 6months, but there were no statistically or clinically significant differences with both groups. 4. The change of gingival recession in both groups was increased significantly at 3, 6months, but there were no statistically or clinically significant differences with both groups. 5. The significant reduction of the pocket depth and clinical attachment level exhibited marked changes at 3 months in both groups. In conclusion, the results of this study suggest that there are no statistically or clinically significant differences between with and without bioabsorbable membrane on treatment of classII furcations using allograft and PRP
