Abstract
Single-rooted teeth were instrumented and filled in vitro with a lateral condensation
of gutta-percha with sealer. Following obturation, the tooth apices were treated by
various retrograde procedures. The teeth were then coated with ethyl acetate, immersed
in 45Ca solution, washed, and sectioned, and autoradiographs were used to compare the leakage
of the various techniques. Statistical analysis indicated that lateral condensation
produced a significantly better seal than any retrograde technique tested except retrofilling
with Super EBA cement and that a significantly worse seal was obtained with amalgam
retrofill when compared to all retrograde techniques except cold-burnished gutta-percha
following apicoectomy. No significant difference existed between other group combinations.
