As discussed here, tooth resorption is not the normal process associated with the normal loss of deciduous teeth but that which constitutes pathological change and is usually observed when the teeth have been subjected to unusual stimuli. Resorption is described as internal resorption or external resorption on the basis of the origin of the odontoclastic cells. Whether they came from outside the tooth and the periodontal membrane or internally from cells of the pulp. this differentiation is of more than academic interest, since the two types of resorption produce changes that are radiographically distinct and the most appropriate treatment depends on their recognition.
