The aim of the present study was to evaluate the prevalence, distribution and severity of erosive wear noncarious cervical lesions and to establish their association with various clinical and biological parameters of patients. The investigation, developed along 3 years, included 360 subjects with ages between 18 and 75 years. Following a complete clinical examination, which included a minute anamnesis, the history and personal and hereditarycolateral antecedents were established and the observation sheet, also describing the alimentary habits and the life style, was filled in, for the detection of the factors involved in the etiology of cervical non-cariogenous erosive lesions. The following data was recorded with reference to the: 1. presence/absence (prevalence) of erosive wear non-carious cervical lesions in the group under investigation, and their distribution (prevalence) as a function of patients’ sex, group of age, environment and etiological factors; 2. evaluation and distribution of such lesions as a function of their severity, according to the BEWE (basic erosive wear examination) index and affected dental structure. In the investigated group the prevalence of erosive wear lesions was of 45.27%. Erosive lesions affected mainly the 46-75 year group of age, women and urban patients. The most affected group of teeth were the mandibulary molars and mandibulary premolars, followed by maxillary premolars, maxillary frontal teeth, mandibulary frontal teeth, and maxillary molars, respectively. The highest values of prevalence were registered on sextants 6, respectively 4, followed by sectants 2, 1, 5, respectively 3.Keywords:
