The authors describe a centralized suction device worked on the fluid-ring pump principle. The advantages offered by this multi-phase unit, which works in a watery milieu, to stomatological practice are presented in the light of 18 months of clinical use.
The author describes a combined bureau and instrument cabinet that is suited for clinical use as well as for measuring and planning work in orthodontic practice.
With regard to a modified capsule program permitting to predose dental materials in stomatological practice, the clinical use of an amalgamator designed for predosed capsules is evaluated from economic and ergonomic aspects. During two and a half years of intensive utilization, this amalgamator has proved very successful. Therefore, it may be recommended as an essential element of the capsule system.

Agar diffusion plate tests were performed on five strains of micro-organisms to characterize the disinfecting properties of nine denture cleaners. Furthermore, the liberation of oxygen was determined as a function of time, and the course of pH variation of the various cleaning solutions was studied. The highest oxygen concentrations and the best antimicrobic activities were achieved by the preparations Eladent G and T.
Of 64 burials at the Schönstedt common burial-ground which dates from the neolithic age, 49 well-preserved dentitions were examined for caries incidence, periodontal disease, abrasion, hypodontia and polydontia, tooth alignment and occlusal position. The results obtained are discussed with regard to contemporaneous and modern conditions.
Starting from a conventional stomatological work place, the author shows how to arrive stepwise, by reconstruction and new aquisitions, at two conceptions which enable the treating team to work in seated position.
Design and mode of action of a suction apparatus worked on the vacuum cleaner principle. A suction apparatus worked on the vacuum cleaner principle is presented as a part of a modern work-place conception.
The author describes an inserted basket system which conformes to the size of the dental instrumentarium and of the tank of the ultrasonic cleaning apparatus.
A right-angled cannula is presented that is suited for unhindered suction in the regions of the left maxilla and mandible and of the upper anteriors.
Allowing for the work areas, the sequence of operations and the kind of treatment under direct or indirect vision, the author proposes working positions for sit-down dentistry which harmonize with the patient's posture.
