Abstract
In the anterior area of the mouth, the interdental papilla is important for dental hygiene and appearance. When it disappears, unpleasant "black triangles" form, which affects patients' self-confidence in their smiles and makes oral hygiene more difficult. The loss of interdental papilla is caused by several variables such as tooth shape, periodontal disease, and aging. Although surgical treatments have been utilized to restore or retain missing papilla, their predictability remains unknown. In response, researchers have investigated non-invasive procedures, such as the use of fillers such as hyaluronic acid (HA). Owing to its capacity to increase tissue volume and bind water, HA, a naturally occurring polysaccharide with special rheological qualities, has become a popular choice for use as a dermal filler. It shows promise when used to cure interdental papilla loss; the effects usually last for six-12 months. This review article explores the development and history of papilla rebuilding methods, emphasizing hyaluronic acid as a cutting-edge and successful method for regaining both periodontal health and aesthetics.
