Abstract
OBJECTIVE. The purpose of this study was 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).
MATERIAL 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 six months postoperatively.
RESULTS. The average values for the GRD measured six months postoperatively for the control group were 0.37±0.36 mm and 0.70±0.41 mm for the test group. The results for CAL for the control group were 2.01±0.44 mm and 2.28±0.50 mm for the test group, while the mean percentage of root coverage (RC %) was 90.29±9.05% for the control group and 80.48±10.19% for the test group. The values for GTH were 1.04±0.16mm for the control group and 0.92±0.09 mm for the test group.
CONCLUSION. Both 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.
