[Evaluation of quality and function of stainless steel crowns for primary molars]

A study of 30 stainless steel crowns placed on primary molars by students od Stomatology was performed. The following criteria were taken into consideration: occlusion, proximal contact, marginal extension, marginal adaptation and absence of cement. In spite of the numerous errors in the five criteria studied, only three crowns were considered unacceptable and not clinically functional.
