Objective: To review the historical and current periodontal phenotype classifications evaluating methods and characteristics. Moreover, to identify and classify the methods based on periodontal phenotype components. Overview: Several gingival morphology studies have been frequently associated with different terms used causing confusion among the readers. In 2017, the World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions recommended to adopt the term “periodontal phenotype”. This term comprises two terms, gingival phenotype (gingival thickness and keratinized tissue width) and bone morphotype (buccal bone plate thickness). Furthermore, gingival morphology has been categorized on “thin-scalloped”, “thick-scalloped” and “thick-flat” considering the periodontal biotype. However, by definition, the term phenotype is preferred over biotype...

Background: Free gingival graft (FGG) and connective tissue graft (CTG) are two of the most commonly techniques performed in periodontal and peri-implant plastic surgery. Although several outcome measurements have been pro posed for evaluation of palatal wound healing and patient morbidity, a comprehensive review about these variables is lacking. The objective of this review is to present comprehensive information about outcome measurements related to postoperative palatal wound healing and postoperative patient-reported morbidity after FGG or CTG procedures. Material and Methods: An electronic search of English language dental literature in the Medline database via Pub Med access was conducted from May 1994 to May 2020 following the PRISMA guidelines. Electronic search stra tegy complemented by hand search of impacting related dental journals, and the reference list of all included stud...
