Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes.[1] These lesions vary in shape from regular depressions that look like a dome or a cup, to deep wedge-shaped defects with the apex pointing inwards.[1] NCCLs can occur either above or below the level of the gum, at any of the surfaces of the teeth.
