 Non-carious cervical lesions, NCCLs, are irreversible losses of dental hard tissues at the cemento enamel junction, caused by occlusal forces without any acute traumatic event. These lesions can be found in the cervical region of the teeth, usually on the buccal surface of the premolar teeth. They typically take the shape of a wedge, with a reticular location. When multiple NCCLs are present, they can be detected using optical coherence tomography, OCT. This technique is an effective adjunct tool for evaluating the clinical forms of NCCLs.
