[Experimentation of apiarian preparations for the direct and the indirect capping of the dental pulp].
With a view to extend the range of biologically active preparations for the direct and the indirect capping of the dental pulp the authors have used a paste made from an alcoholic solution of propolis and zincoxyde. The study was carried on in 150 teeth with indirect capping of deep cavities, and 50 teeth with direct capping. The evolution of the cappings was followed clinically, radiologically and morphologically. The results obtained showed that the paste with propolis exerts effects similar to those of zinc eugenate. The morphologic study of the indirect capping showed that secondary dentin developed shortly after the application of the paste, and that it was followed by the development of pulpolites and the sclerous transformation of the pulp. In teeth with direct capping a protective film developed at the opening of the dental chamber. With time the pulpal wound undergoes cicatrization by a process of fibrosis and there is a trend to remineralization. No areas of pulpal degenerescence were found the rest of the pulpal tissue, and this suggests that the paste is more histophilic than the pastes based on calcium hydroxide, with which an area of necrosis occurred at the opening of the chamber, and calcium and fibrous degenerescence occurred in the coronal pulp.
