In the 1990’s, the Swedish govt suggested the discontinuation of amalgam as restorative in paediatric dentistry. Since the mercury content in amalgam comprises an environmental hazard, its use has decreased. The usage of resin composites is growing, but the polymerisation shrinkage of the material is still undesirably high, and also the handling of uncured resin could potentially cause contact dermatitis. A brand new restorative material has been created in Sweden as a substitute for amalgam and resin composite: a calcium aluminate cement (CAC). CAC continues to be marketed as a ceramic direct restorative for posterior restorations (class I, II) and for class V restorations. This dissertation examines mechanical properties and clinical reliability of the calcium aluminate cement when applied for class II restorations…..
