Introduction:

dental erosion is the pathological, chronic, localized and painless loss of dental tissues, produced by the chemical action of acids, where the action of microorganisms is not involved. In recent years, a significant increase in the prevalence of this pathology has been observed, especially in children and adolescents.

Objectives:

to determine the prevalence of dental erosion in temporary dentition using the Basic Erosive Wear Examination Index (BEWE) in children between 5 and 12 years of age, and to determine the eating habits that may favor the development of these lesions.

Methods:

a cross-sectional study was carried out on a sample of 391 children. A survey was conducted where eating habits were analyzed and a clinical examination of the temporary teeth was performed using the BEWE index.

Results:

the prevalence of dental erosion in the studied sample was 19.7 %, with mild lesions being most common.

Conclusions:

in all, 30.62 % of the studied population had a low risk of dental erosion, and risk was seen to increase with consumption of acidic beverages (soft drinks, isotonic drinks and fruit juices) and acidic fruits such as oranges, grapes and apples.
