The results indicate that both surgical approaches are effective in addressing root coverage. However, when an increase in gingival dimensions (keratinized tissue width, gingival/mucosal thickness) is a desired outcome, then the combined technique (CPF + SCTG) should be used.
Within the limits of the present study, it can be concluded that CPF provides benefits for both smokers and non-smokers in terms of root coverage of shallow Miller Class I recession defects. However, cigarette smoking negatively impacts the clinical outcomes, specifically residual recession, percent root coverage, and frequency of complete root coverage.
Our results showed that EMD, IGF-I, and the combination of both factors stimulated PDL fibroblast proliferation, whereas these factors did not affect adhesion, migration, or expression of type I collagen of these cells.
The long-term stability of CPF outcomes is less than desirable, particularly in smokers. Two years after a CPF procedure, smokers have significantly greater residual recession compared to non-smokers both statistically and clinically.
Both GTR and CPF procedures result in root coverage. The amount of root coverage obtained with CPF was greater than that observed with GTR, although GTR resulted in significantly greater ACL gain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
