Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
Hypodontia is less common in the primary dentition, [6] with reported prevalence rates ranging from 0.5% in the Icelandic population [89] to 2.4% in the Japanese population. [90] In the primary dentition the teeth reported as most likely to be missing are the lateral incisors, both maxillary and mandibular.
Teeth displaying enamel hypoplasia lines, linear defects of enamel that form during crowns development as a result of periods of nutritional stress or disease during infancy and childhood Enamel hypoplasia is a risk factor for dental caries in children including early childhood caries (ECC), which continues to be a burden for many children.
An animal's dentition for either deciduous or permanent teeth can thus be expressed as a dental formula, written in the form of a fraction, which can be written as I.C.P.M I.C.P.M, or I.C.P.M / I.C.P.M. [10] [11] For example, the following formulae show the deciduous and usual permanent dentition of all catarrhine primates, including humans:
When primary teeth are near exfoliation (shedding of primary teeth) there will inevitably be an increase in mobility. Exfoliation usually occurs between the ages of six and thirteen years. It usually starts with the lower anterior teeth (incisors); however, exfoliation times of the primary dentition can vary.
Dental anatomy is dedicated to the study of tooth structure. The development, appearance, and classification of teeth fall within its field of study, though dental occlusion, or contact between teeth, does not. Dental anatomy is also a taxonomic science as it is concerned with the naming of teeth and their structures. This information serves a ...

The most striking example of this is in Paranthropus robustus, with half of all primary molars, and a quarter of permanent molars, displaying PEH defects, thought to be caused by a specific genetic condition, amelogenesis imperfecta.
