The demand for esthetic restorations has resulted in an increased use of dental ceramics and is the main alternative restorative material to tooth structure due to its favorable properties. Therefore, the aim of this work is to study the evolution of ceramic systems, involving different types and properties, indications, and clinical issues as aesthetic, cementing and longevity. In a detailed and advanced search in the database PubMed, 98 articles were found using the following key words: dental porcelain dental all-ceramic and ceramic according to the criteria for inclusion and exclusion left only 35 articles for review. Several ceramic systems are available in the market, making the prosthetic professionals need a constant recycling about their properties and directions, since good results are due to the selection of the best material for a particular case in all the skill of the practitioner.

The purpose of this study was to evaluate surface rugosity among indirect esthetic materials (Vita VMK 95, Solidex, Artglass, Targis). Ten samples of each material in the cilindric shape with dimension 6 x 6 mm were manufactured. The surface were submitted to finishing and polishing, according to manufacturer's recommendations. The samples were submitted to measuremenst, using the Hommel Tester T500 device. The average values of maxim surface rugosity among the materiais ín question, were 5, 73pm; 5, 15pm; 6, 83 j.Jm e 3, 72 j.Jm, respectively. Sample were also subjectted to variance analysis- ANOVA (5%), had detected significance. Concluded that the material Solidex did not present significant statistical differences among groups, while Targis presented significant statistical differences in relation to the Artglass and the ceramic Vita vmk95.
