The validity of reported tensile bond strength utilizing non-standardized specimen surface areas. An analysis of in vitro studies.
OBJECTIVE
To assess and discuss the true value and perceived relevance of present day dental adhesive tensile bond strength studies. There are flaws and inconsistencies present in the data due to the inherent variations in testing methods, conditions, and types of samples prepared. In particular, surface areas of specimens need to be standardized. This review considers the significant impact of different surface areas of tooth specimens utilized in testing.


RESULTS
On review of the data, relatively higher MPa values do not necessarily indicate improved dental adhesive products or procedures.
