GONCALVES DE FIGUEIREDO, Viviane Maria; LIMA DOS SANTOS, Rosenês  and  DANTAS BATISTA, André Ulisses. Study of characteristics and hypersensitivity of non-carious cervical lesions in patients with occlusal changes. RFO UPF [online]. 2016, vol.21, n.3, pp. 294-299. ISSN 1413-4012.

Objective: to verify the characteristics, length, and depth of the lesion, and the hypersensitivity of non-carious cervical lesions (NCCL) in patients with occlusal changes. Subjects and methods: by means of a cross-sectional observational study, 58 patients of both genders, between 18 and 71 years old, with lesions were evaluated at the Occlusion services of the cities of João Pessoa and Campina Grande, PB, Brazil. Length, depth, and hypersensitivity of NCCL were determined by clinical examination performed by a single calibrated examiner. Data were analyzed using descriptive and non-parametric (ρ Spearman coefficient) analyses at 5% significance level and 95% confidence interval. Results: supragingival extension with grade 1 tooth wear index was prevalent in the population studied. Age was positively correlated with increasing depth of the lesions. Cervical hypersensitivity was present in 74.13% and more prevalent in lower premolars (22.34%). Conclusion: Lesions with supragingival extension were prevalent among patients of the research. The group of lower premolars was mostly affected by dental hypersensitivity, and the increasing depth of lesions was associated with the presence of NCCL hypersensitivity.
