NCCL - Non-Carious Cervical Lesions
Non-carious cervical lesions (NCCL) occur near restorations and are characterized by a loss of hard dental tissue near the cement-enamel-junction. Commonly, their shape is like a wedge with the apex pointing inwards. Other times, they appear as regular depressions, like a dome or a cup. Their main characteristic is the presence of hard-mineralized tissue. Often the NCCL is painless and does not affect esthetics; thus the patient may not be aware they exist.
