RÉSUMÉ
Non-carious cervical lesions are usually described as “tooth substance loss.” Such process includes attrition, abrasion, erosion, abfraction, localized non-hereditary dentinal hypocalcification, localized non-hereditary dentinal hypoplasia, amelogenesis imperfecta, dentinogenesis imperfecta, and tooth trauma. The non-carious cervical lesion is complex lesions in which there is a loss of enamel, dentin, cementum, bone and keratinized attached gingiva. Furthermore, there is gingival crest disharmony, poor emergence profile, loss of identifiable cemento-enamel junction, Miller’s recession class, and dentin/root sensitivity. The treatment of this non-carious lesion includes restorations such as glass-ionomer cement (GIC), composites, and Resin-modified GIC. We can even restore them with porcelain fused metal crowns or full ceramic crowns.
