The material already exhibits a surprisingly good surface quality after mill- ing; this simplifies the further manual processing as well as saving time. Polishing, stain- ing and glazing are particularly quick and simple with the corre- sponding polishing sets. No fir- ing cycles, e.g. a glazing firing, are required. We’ve received only positive feedback from the patients; this case is no excep- tion. Along with natural esthet- ics, the surface of the restora- tive material feels smooth to the tongue, which contributes to a high degree of wearing comfort. On account of the special ma- terial concept and its result- ing physical properties, such as an elasticity modulus of 30 GPa and a Weibull modulus of 20, etc., VITA ENAMIC is much less vulnerable to the shear and compressive forces acting on the stomatognathic system than many traditional CAD/CAM ce- ramics. As a result, it offers a particular potential for certain risk groups, such as patients with parafunctions (teeth grind- ing and clenching), regardless of the manufacturer’s official recommendation for use only in the case of patients with normal occlusion.

A few recent investigations at the preclinical level have shown that applica- tion of newly commercialized calcium-silicate based materi- als in deep dentinal cavities re- sulted in rapid stimulation of the biosynthetic activity of odonto- blasts and dramatic reduction of dentin permeability. Again, all these data have to be confirmed clinically. In conclusion, despite the fact that numerous scientific articles studied experimentally or clinically the pulp protective materials in experimental or clinical investigations (Bjorndall et al. 2010) and a number of crit- ical and systematic reviews dis- cussed their results, it must be emphasized that they have not been evaluated for the complete range of their effect. Given that application of a calcium hydrox- ide -based material in combina- tion with a glass ionomer, seem to be the best choice according to the guidelines of American Academy of Pediatric Dentistry and the position statements de- livered by the American Asso- ciation of Endodontists, further randomized multi-centered controlled clinical research is needed to assess firstly the overall role of capping material in the VPPT, and then the abil- ity of today used and/or newly developed materials to provide long-term pulp protection.
