A dental material composed of hydrophilic polycaprolactone formed by the process of exposing a hydrophobic caprolactone to ionizing irradiation from a radiation source selected from the group consisting of an Electron Acceleration (E beam), Gamma II, Cobolt, X-ray or a source of UV radiation to form a cross linked polycaprolactone composition consisting of two distinct phases one of which is soluble and the other non-soluble, and adjusting the duration of ionizing radiation and/or the intensity of the radiation to cause the concentration of the soluble phase to be above at least about 65% by weight of the cured polymeric composition whereby the hydrophobic caprolactone becomes hydrophilic.
