[Comparative study of Uromiron and 38% Lipiodol in sialography].

A comparative study was undertaken to assess the properties of uromiron and lipiodol 38%, which are used as radiopaque materials in sialographic techniques, on 25 young adult outpatients of both sexes that were seen at the Dental School, University of Chile, Santiago. It was found that, although the radiopaque properties of uromiron were less than lipiodol 38%, the can be improved by increasing the amount of material injected into the duct system of the salivary glands. Likewise, uromiron exhibited a proper biological tolerance and a rapid emptying time, therefore the use of uromiron in sialographic techniques seems to be a proper alternative to lipiodol 38%.
