Methods : Electronic literature searches were conducted 2017 to 2022 using the following database PubMed and Wiley using term limited to randomized control clinical trials in English using the PICOS format. Clinical parameters included changes in, Pocket Depth (PD), Vertical Recession Depth (VRD), Keratinized Width (KTW). Results: The research is conducted to identified all full articles and were done manualy from 289 articles, there were 39 articles found in accordence with the tittle and abstract, and only out of which 7 articles were selected for full-text assessment. Finally, 3 articles were selected for detailed evaluation for this systematic review. Conclusion : With the avalaible data, it is concluded that Free Gingival Graft procedure can be a successful modality in the management of Millers Class I or II recession. The FGG gives an impression of being the best treatment option in zones where the gingival recession is present with inadequate width of attached gingiva and vestibular depth.
