GUTTA PERCHA - semi-plastic, isomer of natural rubber (cis isomer). Harder, cannot be stretched reversibly. Polymeric cones of gutta percha with other constituents such as ZnO, barium sulphate, plasticisers and pigments are used. DISADVANTAGES OF GUTTA PERCHA; - micro voids - voids on insufficient packing - difficult to condense - may stick to instrument on condensing - turns brittle quickly after setting - unsuitable for use by itself - not flexible enough to take the shape of the root and completely seal by itself - needs a paste (sealer) - lacks resilience
