Advantages of Hyaluronic Acid and Its Combination with Other Bioactive Ingredients in Cosmeceuticals.

This study proposes a review on hyaluronic acid (HA) known as hyaluronan or hyaluronate and its derivates and their application in cosmetic formulations. HA is a glycosaminoglycan constituted from two disaccharides (N-acetylglucosamine and D-glucuronic acid), isolated initially from the vitreous humour of the eye, and subsequently discovered in different tissues or fluids (especially in the articular cartilage and the synovial fluid). It is ubiquitous in vertebrates, including humans, and it is involved in diverse biological processes, such as cell differentiation, embryological development, inflammation, wound healing, etc.

Impact of connective tissue graft thickness on surgical outcomes: A pilot randomized clinical trial.

Background: The aim of this study was to compare thick versus thin connective tissue grafts (CTG) for the treatment of gingival recession, over a 3-month period.

Methods: Forty-two CTG procedures were performed on single tooth Miller Class I or II recession defects at either premolar or anterior sites in 30 individuals. Procedures were randomized (1:1 ratio) to CTG thickness of 1 or 2 mm (parallel group design).
