title: Frequency, location, and direction of the lateral, secondary, and accessory canals.
abstract: Observation of 1,140 transparent teeth of adult humans was made to verify the frequency, location, and direction of the accessory, secondary, and lateral canals located at the radicular-apical area, at the body of the root, and in the base of the root. In 27.4% of the teeth studied, some type of ramification was observed; these ramifications were usually located in the apical area of the root. The premolars and molars showed the greatest variety of ramifications.
