Abstract
Aim:
To assess the physical and mechanical
properties of plaster of Paris (POP) bandage cast used as a
splinting and casting materials.
Materials and Methods: POP casts were divided into three
Groups A, B and C with 2, 3 and 8 layer for POP bandage,
respectively (n=6 in each group). Handling characters, technical
easiness or difficulties, setting time, weight, diameter and
thickness of the casts were recorded for different groups. The
casts were mounted on universal testing machine and axial load was
applied @ 10 mm/min until failure. The load deflection graphs were
plotted. The maximum force at which failure of the casts occurred
was recorded. Stress, strain, modulus of elasticity (MOE) and
stiffness of casts were calculated.
Result:
Construction of POP bandage cast was messy and required 45-60
min for hardening. 8 layer POP cast was comparatively heavier in
weight and thicker in cross section than 3 layer cast followed by
2 layer cast. Under axial compression, the load bearing capacity
of 8 layer POP casts was more than 2 and 3 layer cast.
Conclusion: The values of load bearing
capacity, stress, stiffness and MOE of cast were the highest for 8
layer POP cast followed by 2 and 3 layer cast. Use if splints with
POP cast is recommended due to its poor mechanical properties.
Keywords: axial load, cast, compression,
physical properties, plaster of Paris bandage.
