title: [Frequency and etiology of noncarious cervical lesions with pulp exposure].
abstract: OBJECTIVE
  Noncarious cervical lesions have a multifactorial etiology encompassing occlusal trauma, toothbrush abrasion, and exposure of enamel to erosive factors. The purpose of this study was to determine the frequency of cervical lesions with exposure of pulp and to analyze their etiology.
  
  
  METHODS
  The study was done in 124 patients (59 women and 65 men) with a mean age of 44 years (15-72 years). Clinical assessment of cervical lesions was based on criteria of the universal tooth wear index for the cervical surface. Additionally, the following findings were recorded: frequency of cervical lesions depending on tooth type, pulp exposure, oral hygiene status, and type of occlusal guidance. The questionnaire consisted of detailed questions concerning toothbrushing, frequency of consumption of some foods, and parafunctional habits. The risk of cervical lesion was estimated with the logistic regression model.
  
  
  RESULTS
  The frequency, localization, and depth of noncarious cervical lesions were related to age of the patient. Very deep defects with pulp exposure were found in 44 teeth. The effect of consumption of acid foods and drinks and of oral hygiene habits on the depth of wedge-shaped defects was corroborated. Correlations between lateral excursive tooth contact, bruxism, and formation of cervical lesions were disclosed, confirming the relationship between occlusal pathology and cervical lesions.
  
  
  CONCLUSIONS
  Elucidation of the multifactorial etiology of cervical lesions is important for proper treatment and prevention of pulp exposure.
