Comparative evaluation of the treatment of gingival recessions with connective tissue graft and platelet-rich fibrin membrane

Purpose: The purpose of this study is to compare the options for treatment of Miller’s Class I and Class II gingival recessions using coronally advanced flap (CAF) and platelet rich fibrin membrane (PRFm) with CAF and connective tissue graft (CTG). Materials and methods: A surgical treatment was carried out on 30 subjects (23 women and 7 men) with a total of 118 symmetrical recessions of Class I and Class II by Miller on different places of the jaws, using two different methods. On one side of the jaw was held a plastic covering of the recessions with CAF in combination with PRFm (test group), and on the other side – CAF in combination with connective tissue graft (control group). The clinical evaluation includes: gingival recession depth (GRD), probing pocket depth (PPD), clinical attachment level (CAL), keratinized gingival width (KGW), gingival thickness (GTH), mean percent of root coverage (RC %). The results were observed for six months postoperatively. Results: The average values for the GRD measured six months postoperatively for the control group are 0.37± 0.36 mm and 0.70±0.41 mm for the test group. The results for CAL for the control group are 2.01±0.44 mm and 2.28±0.50 mm for the test group, while the mean percent of root coverage (RC %) is 90.29±9.05% for the control group and 80.48±10.19% for the test group. The values for GTH are 1.04±0.16 mm for the control group and 0.92±0.09 mm for the test group. Conclusion: Both the compared methods show good results in terms of all evaluated parameters. The group treated with CAF + CTG showed better results with a statistically significant difference for the RC% and the average values for GRD, GTH and CAL. The results of our study demonstrate a good potential for PRFm used in the treatment of Miller’s Class I and Class II gingival recessions.
