The term "cervical lesions" definies all the alterations consisting in a loss of hard dental tissues located along the cement-enamel junction, and may be more specifically defined as carious lesions (LCC) and non-carious lesions (NCCL). The non-carious cervical lesions are characterized by the loss of mineralised dental tissue in the absence of a carious process. This definition includes three different lesion categories: abrasion, erosion and the cervical lesions caused by stress (abfractions). In this paper the authors explain the histological, clinical, preventive findings of NCCL and try to give some guidelines to choose the appropriate material to restore different types of non carious cervical lesions.
