In the treatment of sudden deafness there is no significant difference between Rheomacrodex i.v., Procain i.v., Dusodril i.v., Ronicol i.v., Complamin i.v. or anaesthesia of Ganglion stellatum. We show that good outcomes are attributed to spontaneous recovery. The so called "good effect of early therapy" in sudden deafness is the result of selection of spontaneous recovery. The prognosis of sudden deafness with according vestibular symptoms is less favourable. A definite clarifying of spontaneous recovery needs a prospective randomised double blind study.

The marginal fit of cemented galvanoceramic crowns.

Galvanoceramic restorations were constructed for five extracted teeth. Following cementation, the margins were photographed (magnification X 33) and the prints mounted to produce a continuous image of the entire margin. Cement film thickness measurements were made at 0.1-mm intervals. The five cemented restorations were then embedded in resin, sectioned longitudinally, and examined under a microscope (X 125). The mean gap at the restoration margin, as measured by each technique, was 18 microns and 19 microns, respectively. These results were consistent with the clinical impressions of cemented galvanoceramic restorations completed at the University of Tübingen.
