efficacy of double pedicle graft with and without prgf in treating cl and cl ii gingival recessions

abstract background and aims. the aim of this study was to evalute the effect of double pedicle graft (dpg) with and without plasma rich in growth factor (prgf) in the treatment of miller's cl i and ii gingival recessions. materials and methods. thirty two bilateral buccal gingival miller’s cl i and ii recessions were selected. sixteen of the recessions were treated with dpg and prgf (test group). the remaining fifteen recessions were treated with dpg (control group). the clinical parame ters, including clinical probing depth(cpd), clinical attach ment level (cal), recession depth (rd),recession width(rw), keratinized gingiva width(kgw), were measured at baseline and 1 , 3 and 6 months later. data were analyzed with paired t test. results. after 6 months, both groups exhibited a significant improvement in all the criteria mentioned above. however, none of the groups showed significant differences in pocket depths after 6 months. at the end of the study there were significant improvements in recession depths and widths and clinical attach ment levels and keratinized gingiva width between test and control groups. conclusion. the method using dpg+prgf resulted in more favorable clinical outcomes than only dpg.
