Effect of pigmenting drinks on direct posterior sector restorative materials
An ideal restorative material would be able to adhere to the remaining dental tissue and reproduce natural characteristics of the tooth such as translucency, color, and hardness. The dental market offers restorative materials such as Composite Resins, Bulk Fill, Glass Ionomer and Cention-N. These provide several advantages in the aesthetic field, however, it remains a challenge to avoid the bleaching effects that certain commonly used pigmenting drinks can cause. Therefore, the purpose of this review was to describe the effects produced by pigmenting beverages such as tea, coffee, and coca cola, on the color stability of some restorative materials for the posterior sector, in order to determine which of them is the best aesthetic option to rehabilitate this sector. For this, a bibliographic search was carried out, subject to the last 5 years (2017 – 2021), in databases such as Pubmed, ResearchGate,
Web of science, ScienceDirect, Scielo, EBSCO, Semantic Scholar and Medigraphyc, using as descriptors the words Cention-N, alkasite, composite resin, glass ionomer, bulk-fill resin, color stability, physical properties, beverages, coffee, tea, coca cola, combined with Boolean operators AND and OR. A total of 133 published articles were obtained, of which 17 were selected for providing information relevant to the purpose of this review. The results showed that changes in color stability, regardless of restorative material, appear
after 7 days of immersion. According to the literature reviewed, tea is concluded to be the most pigmenting solution, followed by coffee and coca cola. On the other hand, Cention N is the material with the greatest potential for discoloration.
