Abstract: A method of testing for leakage of a pulp chamber in a modified extracted tooth is provided, wherein the modified extracted tooth comprises enamel, dentine and a pulp chamber. The method comprises: (a) providing an extracted tooth which has been modified by removal of roots and dental pulp so as to create a pulp chamber, the pulp chamber having an opening at one end thereof, which opening is defined by a rim; (b) attaching a first end of a first tube to the rim of the pulp chamber so as to provide an air-tight seal between the first tube and the rim; (c) placing the modified extracted tooth into a liquid; (d) supplying a compressed gas into the pulp chamber via the first tube; and (e) determining visually whether or not bubbles of the gas are released into the liquid at the enamel of the tooth.
