ABNORMALITIES OF STRUCTURE Cases of abnormality in the structure ofteeth may be divided into two large groups— (1) Those acquired during calcification and before eruption. (2) Those acquired after calcification and eruption, and usually the result ofpathological processes in the pulp andperiodontal membrane. The latter cases wdl
