Objective:to evaluate the prevalence of non-carious cervical lesions (NCCLs) in Dentistry students froma private college in Northern Minas Gerais. Materials and Methods:a questionnaire on nutritional habits and oral hygiene was applied, followed by a clinical evaluation of those who had NCCLs with previously calibrated evaluators. The sample consisted of348 students, from the 4th to the 9th semesters;175 students answered the questionnaire and 17 presented NCCLs. The present work was approved by the Research Ethics Committee under number2.000.236. Results:there was no significant difference regarding the sex of the interviewees, with a higher concentration of NCCLsinthe students of the 9th semester, approximately72.73% of the total number of individuals evaluated. There was a higher concentration of injuries in individuals between 18 and 25 years old, approximately81.82% of the total sample. Conclusion:the studyreinforces that NCCLs are multifactorial. Hence, both diet and parafunctional habits can influence the involvement/worsening of injuries,which are present among studentswho are the object of this study.

Non-Carious Cervical Lesions are characterized by slow and progressive loss of hard tissue at the level of enamel-cement junction, without bacterial involvement. This work aimed to address a case report of restorative treatment in Class V cavities in multiple premolars using the direct-indirect technique with composite resin. A 42 year-old male patient presented for esthetic restorative treatment with the complaint of severe dentin hypersensitivity and wedged-shaped non-carious cervical lesions affecting the maxillary premolars. The restorative treatment chosen was a direct-indirect technique with composite performed into three sessions as follows: making the class V composite inlays, cementation, and final polishing. The direct-indirect technique as an alternative to the traditional direct technique has the benefits of a better contour of the restoration, since the finishing and polishing are made extraorally. Besides, the control of the polymerization stress and less discomfort to the patient are other advantages. In the case of direct-indirect class V restoration, the advantages far surpass those of the direct technique. Keywords: Hypersensitivity. Tooth Wear. Composites Resins ResumoAs Lesões Cervicais Não Cariosas se caracterizam pela perda lenta e progressiva de tecido duro próximo a junção cemento-esmalte, sem envolvimento bacteriano. Este trabalho tem o objetivo de relatar um caso clínico de tratamento restaurador em cavidades do tipo Classe V em pré-molares pela técnica direta-indireta com resina composta. Paciente do sexo masculino, 42 anos, queixava-se de forte sensibilidade e múltiplas Lesões Cervicais Não Cariosas na forma de cunha nos pré-molares superiores. O tratamento restaurador escolhido foi a técnica direta-indireta com resina composta realizado em três sessões distribuídas em confecção da peça em resina composta, cimentação e polimento final. A técnica direta-indireta surge como alternativa a técnica direta tradicional trazendo como benefícios um melhor contorno da restauração, uma vez que esta é acabada e polida fora da boca, além do controle do estresse de polimerização e menor desconforto ao paciente. A intervenção restauradora direta-indireta se mostra eficaz devido ao fato de conseguir contornar dificuldades encontradas em técnicas restauradoras diretas. Palavras-chave: Hipersensibilidade.
