title: The effect of cross-sectional area on transverse strength of Amalgapin-retained restorations.
abstract: The transverse strength of large amalgam restorations retained by amalgapins of varying diameter and number was evaluated. Restorations with amalgapin retention fractured with greatest frequency parallel to the pulpal floor through the amalgapin at the amalgam-tooth interface. The findings indicate that the geometric configuration and number of amalgapins was of greater importance to the transverse strength of amalgapin-retained restorations than the total cross-sectional area.
