A non-carious cervical lesion(NCCL) is the loss of tooth structure at the cementoenamel junction level that is unrelated to dental caries. This study was to evaluate the occlusal and periodontal status of teeth with non-carious cervical lesions. We evaluated 105 teeth with non-carious cervical lesions in 35 subjects aged 38-75 years and characterized them based on the shape and dimension, plaque retention, bleeding on probing(BOP), probing pocket depth(PPD), occlusal status, brushing type, hypersensitivity and wear facet.

The results of this study were as follows

1. No significant association was observed between cervical lesions and occlusal contact in lateral excursions.

2. No significant difference occurred in plaque retention, PPD, BOP between teeth with and without cervical lesions.

3. Test teeth had a significantly higher percentage of hypersensitivity and occlusal wear facet than teeth without cervical lesions.

4. Wedge shaped lesions had a significantly higher percentage of plaque than saucer shaped lesions.

5. Teeth with plaque were found to have significantly deeper PPD than teeth without plaque retention in cervical regions.

6. Teeth with occlusal contacts were found to have significantly deeper PPD than teeth without occlusal contacts.

7. No significant association was observed between cervical lesions and PPD independent of plaque retention and occlusal contacts.

Although more knowledge is necessary, our results suggest that occlusal contact and bacterial plaque may influence on periodontal tissue, but NCCL is not directly associated with periodontal health
