Objectives: Reviewing information available about platelet-rich plasma (PRP) applied to dental treatments, introducing the general concept of PRP, as well as analyzing actual data about, and challenges faced by, the dental field. Data & sources: The current study analyzed the most informative publications about PRP application available in this field and gathered the maximum information about it as possible. Conclusions: PRP use, either alone or in association with other biomaterials, can significantly favor different fields such as tissue engineering, since it is an innovative technique that attracts the interest of clinicians and basic scientists. However, it is necessary conducting better designed and controlled experiments to enable successful tissue healing based on PRP use. Clinical significance: The current review can be used by clinicians as source of information about the actual rules and protocols adopted in the herein addressed field, besides providing specific examples of such applications.KeywordsPlatelet-rich plasma; Dental treatment; Plateletgrowth factors; Nanotechnology; Bone regeneration; Surgery.
