Abstract

Introduction: the present study aimed to compare the amount of root coverage using connective tissue graft or platelet-rich fibrin with  Coronally advanced flap.


Materials and Methods: The present clinical trial study was performed on 24 patients with Miller class I and II gingival recession who were randomly divided into 2 groups of 12 patients. In one group, connective tissue graft technique with coronally advanced flap (CAF) was used and in the other group, platelet-rich fibrin technique with coronally advanced flap (CAF) was used. In both groups, factors such as probing depth, recession height, recession width, keratinized tissue width, clinical attachment level, gingival biotype and root coverage percentage and gingival thickness in the time periods before the study, one month, three months and 6 months were evaluated and Next, the study findings will be analyzed using SPSS software and Chi-square, Mann-Whitney and Friedman statistical tests.


Results: The results of the present study showed that the percentage of root coverage in the CTG group was 74.68 29 29.31% and in the L-PRF group was 70.42 31 31.85%; Statistically, the coverage of the two groups is not significantly different from each other (P value = 0.579). Probe depth, recession height, recession width, clinical attachment level, biotype and gingival thickness were not significantly different in both techniques (P value> 0.05). Adhesive and keratinized gingival width in CTG group was significantly better than L-PRF group (P value <0.001).


Conclusion: Based on the results of this study, it seems that the use of L-PRF like CTG with coronally advanced flap is effective in the treatment of gingival recession.
