Facts Sources. The sources of facts taken into consideration for this study would be the scientific search engines like google PubMed Embase, and Scopus Elsevier; moreover, a manual search was carried out in the textbooks relating for the topic. four.4. Search. The study was conducted once the search criteria have been identified. The key phrases have been scientifically evaluated and criticized by the diverse authors, as a way to get the highest attainable quantity of benefits and limit the risk of bias. Once an agreement was identified around the search phrases, the search was carried out in the search engines like google listed within the earlier paragraph on 01/05/2020. The key phrases employed are as follows: “”guided bone regeneration “AND” development factor””. 4.five. Study Selection. The selection of the results from the study was carried out according to the parameters listed inside the previous paragraphs. Following the application.
