Abstract

The author discussing the subject - specifications for new materials wich may be abailable in Dentistry - or - Trends in Standardization of new Dental Materials, indicates the possibilitty of different opinios with regard to specifications when we are endeavoring to evaluate a new material which occasionally appears or is likely to appear in the field of dentistry. The proof or validity of a test toda is very difficult to arrive at categorically, considering the enormous difficalty of carrying out the tests and, the limited experience in statistically valid clinical evaluation. He concludes that it seems rarional to evaluate new materials which appear in the dental field, initialy according to specifications already existing for materials, wich the new material may eventually suplant or be employed as substitute.
