It is essential that a competent bond should exist between the gutta-percha point used to obturate a prepared root canal and. the sealer cement, in order to avoid the risks of both periapical leakage and possible disruption of the point during preparation of the tooth for a post crown. An experimental method was established whereby disruption between the two media could be examined. Shear tests were carried out using both smooth surfaced and sandblasted gutta-percha points, and comparisons in their bond strengths were made. Statistical analysis showed that roughening the gutta-percha points significantly improved the bond strength between point and sealer. [ABSTRACT FROM AUTHOR] |
