The research was divided into three steps: 1) clinical assessment; 2) oral-hygiene practices self-report questionnaire; and 3) analysis of toothbrush filament deformations. After the clinical exam the participants were divided into two groups, a control group (without NCCLs) and a test group (NCCLs), according to NCCL presence. The data were statistically analyzed with SPSS 16.0 software, using t-test, chi(2), Fisher exact test, and Spearman correlation.Results: NCCLs were present in 53% of the subjects. The presence of NCCLs was marginally statistically associated with age (p=0.15) and proportionally more prevalent in male (80%) subjects (p=0.01). NCCLs were more concentrated in the posterior-superior quadrant (93%) in both the right (90%) and left (55%) sides of the mouth. The direct rank correlation was presented between presence of NCCLs and toothbrush firmness; and between number of NCCLs and age and force applied during toothbrushing.Conclusion: Within the limitations of this pilot study, the use of medium and hard toothbrushes and greater force applied during toothbrushing might contribute to the development and/or aggravation of NCCLs.581-589engArtigo10.2341/10-152-SWOS:000296955300003Acesso restrito5691730284259344
