Abstract

Magnetic resonance imaging have been used nowadays as one of the accepted tool for diagnosis, estimation, and evaluation of many of human been disease; in dentistry, many of prosthodontics patients and "maxillofacial-prosthesis" patients may fall under the category who might be subjected to routine "MRI" check-up either for follow-up of certain disease or cancer patient for determination the degree of healing or metastasis, thus, there has been growing interest in the research of the possible effect of "MRI" procedure on different component of "dental appliances" wears by those patients and one of these components is "heat cured acrylic resin".
Material and methods: total samples of (454) were prepared from acrylic based heat cured denture material, which divided into two main groups "Clear, Pink", each main group was subdivide, into four groups according to exposure to "MRI" control;(5,15 ,30)minute each of the four sub-groups undergo different tests" tensile strength,  hardness(Rockwell) test, dimensional accuracy test, color change by spectrophotometery, surface roughness, water sorption, residual monomer release "FTIR" and "NMR". Conclusions: it was concluded that exposure to "MRI" at different periods of time lead to altering of some physical properties at different level of significant with the exception for one to two experiments water sorption and residual monomer  which showed less significant than other tests done. Also, FTIR and NMR tests demonstrated a change in vibration of bonds  between two, atoms but without rotation of molecule  without alter the main chemical structure of material.
