[Animal experimental tests of a new filling material (Isocap)].

An experimental investigation with animals (Rhesus monkeys) concerning pulp tolerance to two premeasured dosages of calcium hydroxide cement (Reocap and Reocap-E) as well as a pre-measured dosage of filling material (Isocap) in an injection capsule was carried out (78 class V cavities). As with the negative controls, a very slight reaction, or none at all, developed in response to the two calcium hydroxide cements and the new filling material, with and without application of capping material. When five other accidentally exposed pulpae were dissected, direct capping under the corresponding preconditions (punctate exposed pulpa, longer storage period for calcium hydroxide cement) showed the characteristic formation of reparative dentin.

[Antimicrobial properties of cements with and without copper content].

Copper-containing cements seem to inhibit bacterial growth better than copper-free materials. Twenty-four hours after insertion, a statistically significant difference is noted. The initial bactericidal effect of copper-free cements declines considerably as compared to copper-containing cements. The results obtained largely correspond to those given in the literature. The method used of including bacterial suspension in a liquid medium is suitable to establish dose-reaction curves for dental materials.
