Non-carious cervical lesions in dentistry (NCCLs) encompass a diverse array of pathological conditions affecting tooth structure, which are quite distinct from traditional caries-related tooth damage. This lecture will provide a concise overview of the multifactorial etiological reasons, clinical manifestations, differentiation and management strategies of NCCLs.  Erosion, abrasion, attrition, and abfraction represent the different categories of NCLs, each influenced by distinct contributing factors such as dietary habits, oral hygiene practices, parafunctional habits and occlusal forces. Clinical examination, including thorough patient history and tooth surface analysis, aids in accurate lesion identification and categorizing. Different management strategies range from preventive measures to therapeutic interventions ranging from minimally invasive restorative techniques to comprehensive rehabilitation protocols. A comprehensive understanding of NCCLs is essential for dental practitioners to effectively diagnose, manage, and prevent these conditions, thereby promoting optimal oral health and enhancing patient care outcomes in the contemporary dental practice.
