简要总结

The present randomized clinical trial is aimed at evaluating the efficacy of recombinant human platelet-derived growth factor in combination with collagen matrix for the treatment of multiple adjacent gingival recessions

详细描述

Despite the fact that gingival recession is most often a generalized condition rather than being localized to a single tooth, most of the data currently found in the literature pertains to the treatment of localized gingival recessions.

The gold standard treatment for this condition involves the use of an autogenous connective tissue graft, that is associated with increased patient morbidity.

Biomaterials have progressively gained popularity due to their advantages when compared to autogenous grafts, such as unrestricted availability, avoidance of a secondary surgical site, reduction of the surgical time, and the patient's preference.

Collagen matrix is one of the most used soft tissue substitute for the treatment of gingival recessions. Combining this scaffold material with a growth factor could enhance its outcomes. In particular, root coverage using platelet-derived growth factor can also promote regeneration of new cementum, periodontal ligament and bone.

Therefore, the aim of the present study is to investigate the effect of platelet-derived growth factor in combination with collagen matrix outcomes for the treatment of multiple adjacent gingival recessions.
