Introduction: This work sought to study the etiological factors of non-carious cervical lesions (NCCL) in a Burkinabe population consulting at
the Municipal Center for Oral Health of Ouagadougou.
Materials and methods: This was a cross-sectional and descriptive study, carried out over the period from August 1 to October 31, 2020. The
study population consisted of all adult patients diagnosed with NCCL (abrasion, erosion, or abfraction). The etiological variables assessed were
the oral hygiene modalities, intrinsic acidity, extrinsic acidity, parafunctions, malocclusions, and stress.
Results: During the investigation period, 595 patients were examined and 82 of them had at least one NCCL, for an overall prevalence of 13.8%.
Extrinsic factors (citrus and other fruits, sodas, fruit juices and energy drinks, wine and alcohol, and vinaigrette) constituted 50% of the erosion
factors that were investigated. Horizontal brushing (traumatic brushing) performed by the majority of patients (82.9%) was the major etiology
of abrasion. In terms of abfraction factors, stress and malocclusions were the most represented etiologies, at 42.7 and 29.3%, respectively.
Conclusion: Non-carious cervical lesions (NCCL) have multifactorial etiologies. Early diagnosis of signs of wear and tear would allow taking the
necessary preventive and restorative measures aimed at tissue preservation.

Etiological factors, Non-carious cervical lesions.
