Oral pathology is the science that treats the nature, causes, and development of oral diseases. It includes both clinical and microscopic study of structural and functional changes that cause or are caused by oral and other diseases. The calcified or soft tissues of the oral cavity, or both, may be involved.
This chapter covers the oral anatomy and physiology of the teeth, the histology of the tissues and supporting structures, and concentrates on the external features of the teeth. The teeth are identified by different sizes, shape, and other characteristics from one person to another. Such knowledge is useful when filling out the dental forms in the health record.
