An apparatus for applying a viscous modification material includes a material source of the modification material and a needle connected to the source. A material for selectively modifying the optical properties of cells comprises a basic material and a modification substance distributed in the basic material at a prescribed concentration, wherein the basic material comprises a viscous fluid, a gel, a two-dimensional or three-dimensional porous substrate or a material which hardens in situ. A diagnostic apparatus for determining the optical properties of cells which have been exposed to such a material and an apparatus for irradiating cells whose optical properties have been differently modified with such a material are also provided.

A storage container () for a suspension used for medical purposes, in particular for ultrasonically assisted treatment of periodontitis, dental cleaning or dental preparation, comprises a flexible pouch (), the interior of which is accessible via a charging and discharging nozzle (). Situated in the interior of the pouch () is a distance element (), in which a groove system () is incorporated. The groove system communicates with the interior of the charging and discharging nozzle (). When the pouch () of said storage container () is pressed flat during removal of the suspension it contains, the opposing sides () of the pouch () are applied during the final phase of emptying against the distance element (). The groove system () contained in the latter however remains clear and forms a path, via which even the last residues of the suspension may be reliably removed from the pouch ().

A device for generating high-frequency mechanical vibrations for dental purposes comprises a current detector ( ) fitted in the supply line of a vibration generator ( ). The output signal of the current detector ( ) is transmitted to one of the inputs of a control circuit ( ), which at its other input receives a supply current nominal value signal. The output of the control circuit ( ) is connected to the control terminal of a controllable oscillator ( ), which together with a power stage ( to ) prepares the supply current for the vibration generator ( ). In this manner, a constant output amplitude of the vibration generator is obtained independent of the load coupled to said vibration generator at any given time.

A dental instrument for sonic or ultrasonic treatment comprises a shank (,) to which a treatment section (,) is joined. The shank (,) and treatment section.(,) are made of matrix-bonded carbon fibers. The instrument can be machined out of a woven carbon fiber fabric or can be a compression molding or an injection molding. The mechanical properties of the instrument can be adjusted by varying the length of the carbon fibers.
