| 释义 |
Non-carious cervical lesions (NCCLs) are defined as dental tissue lost at or near the cementoenamel junction (CEJ), and not relating to tooth decay.[1] NCCLs are common in the dentitions of recent human populations.[2] They may result from several processes including abrasion, acid erosion and abfraction.[3] It is thought recent changes in diet and behaviour may explain the high rate of NCCLs in humans today, including consuming a lot of acidic foods and drinks, as well as tooth brushing techniques. Periodontal disease is often also a contributing factor. Archaeological non-carious cervical lesionsWhen NCCLs are present in archaeological samples they can provide insight into behaviour and diet.[4] Abrasion is the most common mechanism of NCCLs observed in archaeological samples, and results from non-masticatory contact of an object with teeth, often through cultural or therapeutic behaviour.[5] Most NCCLs in archaeological examples are attributed to abrasion, with ‘toothpick grooves’ particularly common.[5] Less commonly acid erosion can cause NCCLs, and is caused by the chemical dissolution of dental tissues by acids of non-bacterial origin, most commonly low pH diets. Abfraction, is almost never seen in the pre-modern samples, leading some researchers to suggest it is a uniquely modern issue caused by recent dietary and behavioural changes.
