Non Carious Crvical Lesions Essay

Non carious cervical or class V lesions (NCCL) are associated with loss of hard tissue, at the cementoenamel junction (CEJ) of the cervical third of the tooth structure. It is also referred as cervical abrasion or cervical erosion (Wood, Jawad et al. 2008). These lesions are commonly presented in a variety of forms to the general dental practitioners; varying from shallow grooves to broad dished-out lesions or large wedge-shaped defects, with sharp internal and external line angles (Sarode and Sarode 2013).
Restoring these lesions with predictable success is a restorative challenge, faced by the general dentist and requires knowledge and understanding of the aetiology of these lesions.
History
Miller in 1907 was amongst the first to relate non-carious cervical lesions, with chemical and mechanical factors in his experimental studies, and observations on the tooth wear (Levitch, Bader et al . 1994).
2003).
Prevalence
Prevalence of non carious cervical lesions (NCCL) can vary from 5% to 85% (Levitch, Bader et al. 1994). The prevalence has been recorded as low as 2% by Shulman and Robinson, and as high as 90% by Bergstrom and Eliasson (Wood, Jawad et al. 2008). This wide variation in the prevalence of NCCL is due to the difference population age group range in the studies. Studies also showed that the prevalence of lesion is higher in older patients. The severity and prevalence increases with age, as patients are retaining more number of teeth nowadays (Levitch, Bader et al.1994). The older patient population has a greater percentage of NCCL. Older patient population are also associated with numerous, larger and deeper sized lesions (Wood, Jawad et al.
