| ABSTRACT:
Introduction & Objective: Teaching human anatomy, at any level,
relies not only on the expertise of a tutor but also on the availability
and use of good teaching aids. Plastination specimens have a
unique position as a teaching aid to exhibit accurate anatomical
structures and are easy to be stored and handled by students. The
aim of this study was to assess the comparative use of polyester
resin instead of silicon in S10 technique of plastination.
Materials & Methods: This is an applied experimental study which
was performed on a human body after fixation of the cadaver .The
polymer was prepared by mixing glycerin and polyester resin and
the cobalt (accelerator) and peroxide (hardening material) were
added to it. Dissection, dehydration, defatization and impregnation
of the body were carried out. Finally, the palatinate of specimen was
compared with the palatinate of Heidelberg university (standard
group). The collected data were analyzed by SPSS software using
paired T-test.
Results: The prepared palatinate specimen was dry, nontoxic and
without noxious fumes and showed a normal anatomical position of
structure. Flexibility, elasticity and traction were compared with
those of standard specimen and no significant differences were
observed. Injected colored polymers in vessels were detected
easily.
Conclusion: According to this study, the palatinate specimen
prepared by polyester resin polymer provided an excellent
opportunity to demonstrate and study the dissected areas of the
difficult structures which can be of great benefit in teaching gross
anatomy. In addition, because of the durability, safety, reduction in
toxic and noxious fumes of formalin, the palatinate specimens can
be unique materials as a teaching aid along with the Wet
specimens. |
