Factors that influence the pigmentation of dental composite resins

Abstract

Abstract

Dental composite resins were introduced in 1962 by Ray Bowen. Currently, they constitute the biomaterials most frequently used in direct restorations, due to their excellent properties, managing to imitate the color of natural teeth; however, despite their evolution, the resins in restorations have a high porbability of becoming pigmented. The objective of this research is to identify the factors that influence the pigmentation of dental composite resins. This research has a qualitative approach and is descriptive; the bibliographic review is carried out through the databases: PubMed, Scielo, Redalyc, and the Google Scholar metasearch engine. Publications in Spanish, English and Portuguese are included; and degree these wer excluded. The results obtained reflected that, in the oral environment, various factors, both intrinsic and extrinsic, can cause the color of the composite resin to change, which alters the patient’s dental aesthetics. It is concluded that, within the intrinsic and extrinsic factors, the composition of the resin, the daily intake of certain beverages, the habit of smoking, the use of mouthwashes, and a failure in the clinical protocol during the restorative treatment are included; therefore, proper handling of the restoration by the professional and the patient is necessary to maintain the color of the resin for longer.
