Attachment of human periodontal ligament fibroblasts to 3 different root-end filling materials: Scanning electron microscope observation.

Objective. The attachment behavior of the human periodontal ligament (PDL) fibroblasts to root-end filling materials

(amalgam and Super-EBA) was compared in vitro to gutta-percha by means of scanning electron microscope.

Study design. Amalgam and Super-EBA were placed in a prepared cavity of root slices of freshly extracted human

teeth and evaluated freshly prepared. Root slices of teeth with cold-burnished gutta-percha filling with AH26 sealer

Pulp revascularization of immature maxillary first premolar

A b s t r a c t
An immature maxillary first premolar in an 8-year-old female was treated using a regenerative approach. The root canal was
gently irrigated with 5.25% sodium hypochlorite without instrumentation under aseptic conditions and then medicated with
calcium hydroxide (Ca[OH]2) for 3 weeks. The Ca(OH)2 was removed, and bleeding was initiated mechanically using a hand
file to form an intracanal blood clot. Mineral trioxide aggregate was placed over the blood clot, and the access cavity was
