[Effect of shape of the impulse used in stomatological electroanalgesia on reduction of toothache intensity].

A study was carried out on the effect of the shape of impulses used in electroanalgesia on the reduction of tothache sensation. The measurements were done in 46 subjects and it was observed that the relative increment of ocurrent voltage producing pain of tooth 13 was after 10 minutes of electroanalgesia with rectangular impulses: P1 = (142.2 +/- 6.8)%, sinusoidal impulses: P2 = (80.6 +/- 6.3)%, and serrate impulses: P3 = (51.0 +/- 4.6)% in relation to the voltage causing pain of the same tooth before electroanalgesia. The mean age of the studied patients: 23.8 +/- 0.3 years. The greatest effect was obtained using rectangular impulses.

[Regeneration of the electromotor force of electric piles in the mouth].

The regeneration of the electromotor force E of the electric piles formed by two amalgam fillings was measured as a function of time t after the moment of interruption of the short contact of their poles. The measurements were carried out in 30 patients at a mean age of 27.0 +/- 08 years. Automatic recording of the equation E = f (t) demonstrated that in the first phase of from several to about a score of seconds the E value rose rapidly, while in the second phase lasting from several scores to over a thousand seconds the E value approached asymptotically its initial value Eo.
