Basic theory behind plastination is to halt the natural ongoing process of decomposition triggered by cellular enzymes in tissues that have been removed from the body of deceased individuals. In this technique biological specimens are impregnated with reactive polymer which replaces all the water and fat giving them physical state approaching living condition and can also be used for electron and light microscopic studies. So the present study was aimed to perform and assess the efficacy of plastination technique in preservation of oral soft tissue specimen for museum purposes and in demonstration of root canal morphology of teeth. Moreover, physical and dimensional changes, in both tooth and soft tissue specimens after each process was also evaluated. Extracted teeth with formalin fixed pulp and formalin fixed soft tissue specimens were taken. Teeth were decalcified first. Both type of specimens were then taken for dehydration, clearing and plastination. Shrinkage was noted following procedures of decalcification, dehydration and clearing. The procedure of plastination resulted in shrinkage in soft tissue specimen but no appreciable changes were noted in tooth specimens. Notwithstanding the problem of shrinkage, plastination offers several advantages over other methods used for study of root canal morphology and over conventional museum techniques for preservation of soft tissue specimens. Thus, plastination proved to be a beautiful admixture of science and art aimed for educational purpose to both the dental students and for the patient education and an excellent museum technique.
