339 Evicrol fillings were clinically re-examined 0,52 to 2 years after insertion. The comparison of the results obtained with those from silicate cement fillings (Hildisch) evidenced that the properties of Evicrol are better. In assessing Evicrol for a prolonged period, special attention must be paid to the higher percentage (18--33%) of discolourations appearing already within 1--2 years.

34 jacket crowns of ceramic material, of plastic and of a combination plastic-ceramic material (Berlin jacket crowns), respectively, were clinically re-examined using a uniform scoring scale. The results obtained show that the Berlin jacket crowns can be ranked between the ceramic jacket crowns and the plastic jacket crowns.

The authors examined in 38 teeth the condition of the pulp stump after vital extirpation of the pulp in relation to the cross-section of the root canal. They found that the wound conditions could not be evaluated in 17 teeth as there was no pulp stump in the apical region. Relatively favourable conditions were seen in 11 teeth, which was achieved only in case of circular or oval cross-section of the root canal. These findings permit the conclusion that the state of the pulp stump after vital extirpation depends upon the anatomical conditions and the accuracy of the mechanical manipulation.
Starting from the importance of work studies aiming of scientific work organization in stomatology, the author points to a method for ergonomic complex analyses designed for the evaluation of factors which exert effects upon the functional unit of stomatologist/stomatological nurse, work place and patient. Certain selected results are reported in detail which have been obtained by means of this method in the framework of a pilot study performed at a university clinic of stomatology. The author indicates and discusses, for example, the results of a time study, the working position and posture, the kind of treatment, the noise exposure, the lighting, the room climate and the equipment of the work place. The possibility of listing some factors in the form of parameters of scientific work organization is illustrated by examples.
