Non-carious cervical lesions (NCCLs) correspond to a pathological loss of hard dental tissue located at the cervical level of the tooth, near the enamel-cementum junction,in the absence of carious processes and bacterial involvement..
The aetiology of NCCLs ismultifactorial, involving the interaction of mechanical and chemical mechanisms, including:
- abrasion, primarily related to inappropriate brushing techniques or the use of abrasive toothpastes;
- erosion, resulting from repeated exposure to acidic agents of intrinsic or extrinsic origin;
- abfraction, characterised by a concentration of occlusal stresses leading to microfractures of the enamel and cervical dentine.
These lesions are frequently associated withgingival recession, promoting dental exposure and increasing susceptibility to external aggressions.
Clinically, NCCLs may manifest asdental hypersensitivity, aestheticalterationsand aprogressive loss of dental substance, which may compromise the structural integrity of the tooth if the aetiological factors are not identified and controlled.
Management relies on earlydiagnosis, the identification and control of risk factors.identification et la maîtrise des facteurs de risque, and aminimally invasive therapeutic approach. When the symptomatology, aesthetics or lesion progression justify it, adhesivecervical restorationsmay be indicated in order to restore function, protect exposed dentine and improve patient comfort.
