Introduction:

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 of 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.

Aims:

The aims of this study were to evaluate the effects of magnetic resonance imaging

on mechanical (tensile strength, hardness), physical (color change) and chemical (FTIR,

NMR) properties at different periods of time exposure.

Material & 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 such as tensile strength, hardness

(Rockwell) test, dimensional accuracy test, color change by spectrophotometry, surface

roughness, water sorption, residual monomer release FTIR and NMR.

Results & 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.
