The sucess of the apical closure depends on the tissue compatibility with paste used.

Several dental work has been demonstrating the high successful levels in using calcium hydroxide as calcified tissue inductor. Calen is a calcium hydroxide paste, enriched with some substances that allow its use in Endodontic for apical closure, without interfering the liberation of (Ca).

Biopulpectomy
... It is necessary to use the calcium hydroxide paste as a "delay curative" between clinical section with substances that preserve the pulp vitality.

Histological cutting, showing mineralized barrier, isolating the filling material from the living cote, free of inflammatory cellules
( case accomplished in human being).

Necropulpectomy
... the topic application is recommended as "delay curative" between clinical session, in the treatment of pulpless and infected root canals, specially in cases of chronic periapical reaction.

Incomplete root formation
"The best option in endodontic treatment of teeth with incomplete root formation, is to stimulate the ongoing root development with medicaments.".

Radiograph revealing a significant periapical lesion and the gutta percha cones.

Radiograph after one year of treament with Calen. Observe the periapical repair and "splendid" calcification of the root canal.

Follow-up after 5 years.
