Non-carious cervical lesions (NCCLs) represent a form of tooth wear, characterized by the irreversible loss of dental hard tissues at the enamel-cement junction, without the involvement of caries and dental trauma. The aim of this study was to highlight the morphological elements of NCCLs via their stereomicroscopic examination and to confirm the role of this examination in the diagnosis of early lesions. In addition, the association between the morphological aspects identified during the stereomicroscopic examination of NCCLs and their etiological factors was determined. For this study, extracted teeth with NCCLs were examined with a stereomicroscope. The morphological aspects of NCCLs were evaluated at magnifications up to 75×. In wedge-shaped NCCLs, the stereomicroscopic examination allowed the identification and measurement of scratches, furrows and cracks. In saucer-shaped NCCLs, the stereomicroscopic examination highlighted the smooth appearance of the walls. The presented study highlighted the role of stereomicroscopic examination in the assessment of NCCL morphology and in their early diagnosis. The study confirmed, in particular, the role of occlusal overloads and tooth brushing in determining the morphology of NCCLs.
非龋性颈部病变（NCCLs）是一种牙齿磨损形式，其特征是在釉质-牙骨质交界处牙体硬组织发生不可逆丧失，且无龋病和牙外伤。本研究的目的是通过体视显微镜检查突出NCCLs的形态学特征，并证实该检查在早期病变诊断中的作用。此外，还确定了在NCCLs体视显微镜检查中识别出的形态学方面与其病因之间的关联。在本研究中，对带有NCCLs的离体牙进行了体视显微镜检查。在放大倍数高达75倍的条件下评估了NCCLs的形态学特征。在楔形NCCLs中，体视显微镜检查能够识别并测量划痕、沟纹和裂纹。在碟形NCCLs中，体视显微镜检查突出了其壁面的光滑外观。本研究突出了体视显微镜检查在评估NCCL形态及其早期诊断中的作用。该研究特别证实了咬合负荷过重和刷牙在确定NCCLs形态方面的作用。
