Hyaluronic Acid in Periodontal Regeneration and Implant Dentistry-A Review

The glycosaminoglycan Hyaluronic Acid (HA) is present in the connective tissue of vertebrates. In the extracellular matrix of soft periodontal tissues, it is the most prevalent glycosaminoglycan with a higher molecular weight. In medical fields such as orthopaedics, dermatology, and ophthalmology, the use of HA in the treatment of inflammatory processes is well established. The extracellular matrix of various tissues, including connective tissue, synovial fluid, and other tissues, contains HA, a naturally occurring linear polysaccharide. Its efficacy in the treatment of inflammatory conditions has been proven. It has anti-inflammatory and anti-bacterial effects in the treatment of gingivitis and periodontitis in dentistry. It could be used as an adjunct to mechanical therapy in the treatment of periodontitis because of its tissue healing properties. Use of HA for implant surface modification has also been extensively studied. HA has proven to be effective in peri-implantitis. The purpose of this review paper is to explain HA’s involvement in periodontal therapy.
