title: Gutta-percha points of apicoectomy. To push or to pull?
abstract: A gutta-percha root-filling point placed during apicoectomy may be condensed by the application of pressure to its coronal end or tension to its apical end. Scanning electron microscopy clearly demonstrates the effect that these techniques have on the adaptation of the root filling to the canal. The pressure method would appear to produce the more satisfactory result.
