Biological aspects of root filling therapy in dentistry

The author focuses on the healing effects of a sterile CaOH paste when used in pulp capping treatment and draws the conclusion that this substance is even more strongly indicated when treating the apical part of the root in endodontical practice. CaOH is a bactericide — pH modified to around 12 — and useful also as an inlay in the root canal, even in teeth with gangrene. The author recommends a root filling method with sterile CaOHin the apical part of the root — stimulating healing and growth of regenerating tissue — which is covered with a plug of a biocompatible material, e.g. sterile silicon in an injectable form, or by a two-component root canal sealing paste. This is considered as a far more biological method than that commonly practised which involves use of chloroform and gutta-percha points which may contain traces of heavy metals.
