title: An objective method for measuring the surface morphology of cavities and restorations in vivo.
abstract: A method was developed for quantifying morphological characteristics of cavities and restored teeth, in a quest for more knowledge of factors which determine the long clinical success or failure of restorations, and which may therefore be used in making objective assessments of their quality. The method involved obtaining sequential silicone rubber replicas of teeth in vivo, sectioning them in planned planes, and making objective linear and angular measurements directly from X 10 photographs of the resulting profiles and from positive models. It would seem that the method could be applied in a variety of clinical investigations.
