Summary This study investigated the prevalence, risk factors and association of occlusive wear with non‐carious cervical lesions ( NCCL s) in the general Chinese population. A total of 1320 subjects were recruited, and multistage and random sampling methods of survey spots were performed. All age groups comprised similar numbers of participants and equal numbers of males and females. Each subject completed a structured interview, and all teeth of each subject were examined by a practitioner to determine NCCL s and occlusive wear. Binary logistic regression was conducted by analysing the association of risk factors with the occurrence of NCCL s. Bivariate correlation analysis was performed by determining the association of NCCL s dimension or depth with the range of occlusive wear facets. Clinical assessment showed that the overall prevalence of subjects diagnosed with NCCL s was 63%. The proportion of subjects or teeth with NCCL s significantly increased with age. Pre‐molars were the most commonly affected teeth. Single variables and interactive effects of variables associated with the occurrence of NCCL s include the following: age group, intensity of toothbrushing, frequency of fresh fruit consumption and interactive effect between intensity of toothbrushing and frequency of fresh fruit consumption. A weak positive correlation of the grading index was found between NCCL s dimension, size or depth and range of occlusive wear facets. This study reported the higher prevalence of NCCL s in the general Chinese population. Implementation of a combined strategy to reduce risk factors of NCCL s could be more effective than individual techniques; meanwhile, the occurrence of NCCL could be related to the wear degree of occlusive defects in the population studied.
