Overview

abstract

  • BACKGROUND: Tooth identification is important not only for anatomists and anthropologists but also for dental practitioners and dental students studying dental anatomy courses. This review paper provides an overview of the significance of tooth identification focusing on the morphological and developmental background. HIGHLIGHT: The process of tooth identification comprises five steps of distinction: (1) between deciduous and permanent teeth; (2) between tooth classes; (3) between maxillary and mandibular teeth; (4) within the same tooth class; and (5) between the left and right sides of a tooth. According to Mühlreiter's features, the mesial half is more developed than the distal half, and the curvature feature is associated with the configuration of the dental arch. Each step of tooth identification refers to effective traits and characteristics. The possibility that systemic conditions affect dental morphology should be considered. Tooth identification is occasionally difficult owing to individual variations (size and shape, supernumerary tubercles, root fusion) and sex-based differences. A tooth type error within the same class is the most frequent error in tooth identification, followed by a left or right side error. CONCLUSION: To understand tooth identification, it is necessary to have comprehensive knowledge of dental morphology. A broad education with regard to tooth evolution and comparative odontology, as well as a thorough understanding of the morphology and function of teeth, which play a crucial role in sustaining life as organs of mastication, is essential.
