The effectiveness of two different @entity6086 pastes; "Calvital and "Dycal", for the direct pulp capping in @entity235 's permanent teeth with incompletely formed roots were evaluated in this study. Forty-eight @entity13913 with incompletely formed apices were obtained from 6 @entity235 's (6 months of age). Exposure sites on contralateral pairs of teeth were capped with either "Calvital" or "Dycal". Then intravenous injections of @entity803 were administered to the @entity235 at various intervals. Animals were sacrificed at 56 days. The teeth were fixed, undecalcified ground sectioned, observed by microradiography, and evaluated by ultraviolet light. In cases treated with "Calvital", a fluorescent line resulting from @entity803 administration 7 days after experimental procedures was seen in the newly formed dentin bridge. In cases treated with "Dycal", a fluorescent line resulting from @entity803 administration 14 days after experimental procedures was seen in the newly formed dentin bridge. Continued physiological root formation was observed well in all teeth. This experiment may explain why some "Dycal" failures occur in the earlier postoperative periods; serves as a stimulus potential for a hardening reaction.
