YAMASHITA, Fernanda Chiguti et al. Prevalence of non-carious cervical lesions and dentin hypersensitivity in Odontology students. Rev. Assoc. Paul. Cir. Dent. [online]. 2014, vol.68, n.1, pp.63-68. ISSN 0004-5276.

The aim of this study was to determine the prevalence of non-carious cervical lesions (NCCLs) and dentin hypersensitivity in Odontology students of the State University of Maringá (UEM) and correlate them to variables oral, behavioral and systemic. Data of 80 students were collected via a questionnaire and clinical examination. The clinical examination was used to verify the dentin hypersensitivity and the presence of lesions on the buccal surface of premolars and first molars. Statistical analysis was performed by chi-square test at 5% significance level. 77.5% had NCCLs, with mean of 2.5 ± 2.8. The teeth with most NCCLs were the first premolar, followed by second premolar and then first molar. The dentin hypersensitivity was statistical in a single tooth (p = 0.00540). No significant diference for age, parafunctional habits, type of toothbrush and acidic diet, between the groups with or without NCCLs. Thus, the occurrence of NCCLs cannot be attributed only to a single etiological factor.
