Background: Gingival recession is one of the most important esthetic problems of dental patients. Different methods have been used to treat gingival recession and cover the exposed root. Most of these techniques are surgical. Using platelets-rich plasma (PRP) to cover the exposed root is a new non-surgical technique. Objective: This study aimed to assess the soft-tissue healing using platelets-rich plasma (PRP). Methods: Fifty patients were divided into two Groups: Group 1 (Miller Class I) included 195 sites of recession and Group 2 (Miller Class II) with 223 sites of recession. Platelets-rich plasma was injected at the site of recession three times for three months with an interval of one month between each injection. Then the degree of Miller Classification was recorded for each site in each visit. Results: In Group 1 and after the three injections, only 6 sites remained as Miller Class I with a percentage reduction of 96.92% from Miller Class I to zero. In Group 2, only 28 sites became Miller Class zero and 90 sites remained unchanged as Miller Class II with 105 sites became Miller Class I. Conclusions: Gingival recession with Miller Class I and II could be treated non-surgically by the use of platelets-rich plasma. It is safe, less costly, easily prepared and applied without any complications.
