The general trend of jaw and oral cavity shrinkage, as well as dental malocclusion presence, has been observed in burial remains across Eurasia.Analyses of remains from areas thought to be in situ (origin) to agriculture, such as those in the Levant region dated to approximately 12,000 years ago, are thought to be where humans first changed from hunting and gathering to a more agricultural ...
The partial scoring system is based on the surface area affected. Within a sextant (i.e. teeth in mouth divided into 6 parts), the most severely affected tooth surface (buccal, occlusal or lingual/palatal)(see dental terminology) is recorded according to the severity of the wear (see Table 1). A cumulative score is then matched to a risk level ...
Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth), when they are replaced by a person's adult teeth. Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion, tooth decay, and gum disease.
Worldwide, approximately 3.6 billion people (48% of the population) have dental caries in their permanent teeth as of 2016. [7] The World Health Organization estimates that nearly all adults have dental caries at some point in time. [2] In baby teeth it affects about 620 million people or 9% of the population. [10]
Attrition, abrasion, erosion or a combination of these factors are the main reasons for tooth wear in elderly people who retain their natural teeth. This tooth wear can be pathological or physiological. [10] The number of teeth with incisal or occlusal wear increases with age. [11] [12] Attrition occurs in 1 in 3 adolescents. [12]

The loss of the permanent dentition is a multi-factorial process resulting from the impact of dental caries, periodontal disease and social factors. People who have lost teeth are referred to as (either partially or completely) edentulous (edentate), however those who have not lost teeth are referred to as dentate. [40]
With the loss of teeth, there is a decrease in this vertical dimension, as the mouth is allowed to overclose when there are no teeth present to block the further upward movement of the mandible towards the maxilla. This may contribute, as explained above, to a sunken-in appearance of the cheeks, because there is now "too much" cheek than is ...
