[Comparative morphological characteristics of the pulp reaction to direct coating with therapeutic packings].

In experiments performed on green monkeys the molar pulp response to direct coating with calmecin and polycarboxylate cement saturated with the potassium nitric solution. Compared, the results of morphological pulp investigation showed the polycarboxylate cement with saturated potassium nitrate solution coating to be most effective. It had a rather good odontotropic effect and increased the protective action of the pulp. Polycarboxylate cement with saturated potassium nitrate solution coating is recommended for clinical trials to treat occasional pulp denudation.
