The aims of this investigation were to analyze permanent tooth crown size and morphology and to perform symmetry analysis between corresponding teeth on the right and the left side. The material comprised 32 Turner syndrome patients aged 7-16.7 years. As controls served 33 normal girls 10.2-16.7 years old.

Based on morphological criteria, a modification of the cusp nomenclature is proposed. Enamel thickness and structure in mouse molars show regional variations. Human Tooth Crown and Root Morphology The Arizona State University Dental Anthropology System Human Tooth Crown and Root Morphology also reflects exciting new developments driven by technology that have significant ramifications for dental anthropology, particularly the recent development of a web-based application that computes the probability that an individual belongs to a particular genogeographic grouping based on combinations of crown and root traits; as such, the utility of Crown Elevations. Cusps: This are conical or pyramidal projections on the crown portion of the tooth that makes up a major division of its occlusal surface. Cusps are found in premolars, molars and canines and each cusp represent a calcified developmental lobe.

Tooth crown morphology

Dental crown morphology was scored on dental casts according to the Turner-Scott Dental Anthropology System. 2018-09-08 · To be most understandable, this chapter will begin by presenting the nomenclature associated with tooth morphology. Next, tooth numbering systems will be described and presented. Third, the anatomy of the crown and root of the tooth will be covered, and an explanation of tooth surfaces and ridges presented. The aims of this investigation were to analyze permanent tooth crown size and morphology and to perform symmetry analysis between corresponding teeth on the right and the left side. The material comprised 32 Turner syndrome patients aged 7-16.7 years.

None of the teeth exhibited more than two cusps. Furthermore tooth crown morphology (the surface that consists of enamel) can only be changed by attrition (tooth wear), breakage, or demineralization once the crown of a tooth has erupted through the gum line (White & Folkens 2005: 127). tooth crown size, as compared to individuals with a normal chromosomal complement (15-25).

The term "anatomic crown" of a tooth refers to the area above the cementoenamel junction (CEJ) or "neck" of the tooth. It is completely covered in enamel. The term "clinical crown" often is convenient in referring to any part of the tooth visible in the mouth, but as a rule the unqualified term "crown" refers to the anatomic crown.
