Solubility and disintegration of a glass ionomer cement
Résumé
The mechanism of erosion of a glass ionomer cement (PR Scell) was studied using two experimental procedures: discs of dental cement were immersed in distilled water under unrenewed conditions as defined by ISO standard or under continuously running distilled water to simulate the oral environment. Both experiments suggest that erosion is important and highly correlated to the cryolithe material included in the formulation of this cement.
