The immuno cross-reactivity of gutta percha points.

Objective: The purpose of this study is to test the postulated immuno cross-reactivity between proteins derived from raw gutta percha (RGP), gutta percha point (GPP) and natural rubber latex (NRL).

Methods: Antigenicity and cross-reactivity of proteins were determined by the FITkit (FITBiotech, Finland) and ELISA inhibition assays.

Results: Antigenicity of proteins derived from RGP or GPP was not demonstrated.
