1. A Comparative Analysis of Staining Potential of commonly used Gum Astringents on a Composite Resin Restorative Material – An In Vitro Study
Aesthetic failure is one of the most common reasons for restoration replacement. One of the major reasons for this problem is surface or subsurface changes which lead to slight penetration and reaction of staining agents on the superficial layer of composite resins. Gingivitis is a disease that causes inflammation of the gums or the soft tissue of the oral cavity that immediately surrounds each individual tooth. Various agents such as antibiotics, anti-inflammatory agents or astringents are used in the treatment of gingivitis. Astringents cause shrinkage and contraction of tissues by constricting small blood vessels, water extraction from tissues or by protein extraction. Gum astringents are topically applied on to the gingival margins. The superficial surface of the composite resin restorations located near the gingival margins often comes in contact with these gum astringents which primarily contain tannic acid along with other components that help in reduction of gingival inflammation. The tannic acid content of these gum astringents may be attributed to the discoloration of the composite restoration. Herbal preparations are gaining importance as they are considered to be safe and affordable. The major strength of these natural herbs is that their use has not been reported with any side effects till date. A few studies have found herbal products effectively reduce gingival inflammation.
