Lesão cervical não cariosa

Abstract

Non-carious cervical lesion This work had the purpose to carry out a review of literature through articles in the English and Portuguese language, from 2004 to 2017, with regard to the non carious cervical lesion (NCCL), addressing mainly the etiological factors of the lesions. The lesions are found in wedge and saucer forms, caused by factors that don't involve microbial origin, are increasingly present in the population, reaching all ages groups and genders, causing discomfort to the patient, either by accumulation of food, factor aesthetic or dentin sensitivity. Because they are of multifactorial origin, they often cause doubts to dentists about the true etiological factor, making the treatment performed isn't satisfactory. Among the factors, the most prevalent in the literature are: abrasion, biocorrosion, abfraction associated with oblique and parafunctional loads. Through the literature review we observed a higher prevalence of NCCL in the premolars, with age being a accumulative factor of causes. The association of etiological factors is directly related to the development and progression mode of the lesions. Thus, the work was accomplished with the purpose of evaluating and comparing the results of some authors, so that we can, in a more concrete way, better understand the NCCLs and evaluate the main etiological factors responsible for its progression.
