Moreover, tooth morphology is facilitated by the oral cavity, which holds the teeth together in the mouth. Tooth morphology also incorporates two main dentition types, which include deciduous and permanent dentitions (Scott et al. 3-5). These dentitions have different types of teeth where deciduous dentition has three main types that incorporate incisors, canines, and molars while permanent dentition has four type that include incisors, canines, premolars, and molars. To comprehend tooth morphology, it is crucial for one to understand the nomenclature first, which is a naming system that is often used to describe or even classify material in the subject of dental anatomy. There are several tooth-numbering systems that include FYI system, universal system, Zsigmondy-Palmer Notation, and Dane or the Hederup system. With regard to structure, each tooth has both root and crown portions where the crown is usually covered with enamel while the root is covered by cementum (Koppe et al. 36-38). These two parts, crown and root, join at an area known as the cement enamel junction. The crown portion of the tooth comprises of three layers that include dentin, pulp, and enamel.
