Reconstruction of Interdental Papilla Using Hyaluronic Acid

The presence or absence of the interproximal papilla is essential concern to periodontists, restorative dentists, and to the patients. The loss of papilla can cause cosmetic deformities (black triangles), phonetic problems, and food debris accumulation. Often the loss of papilla is a consequence of periodontal disease because of gingival inflammation, attachment loss and interproximal bone height resorption.

Several reasons also lead to absence of interdental papillae including:

• Plaque associated lesions, 2) Traumatic oral hygiene procedures, 3) Abnormal tooth shape, 4) Improper contours of the restoration, 5) Spacing between teeth, 6) Loss of teeth.
