title: [One-year clinical evaluation of tooth-coloured materials in non-carious cervical lesions].
abstract: BACKGROUND
  The restoration of non-carious cervical lesions is specific, mostly because of the location of their margins, especially the cervical margin, which is determined in cement and/or dentine. This feature makes the cervical margin more susceptible to micro-leakage, causing marginal discoloration, postoperative sensitivity, development of the secondary caries and loss of the restoration.
  
  
  METHODS
  One of the criteria for inclusion of a patient in this study was the presence of at least two non-carious cervical lesions to be restored with the minimum depth of 1 mm, independently of their location in the dental arch. A total of 60 restorations were placed in 30 patients. and every patient received both tested materials (composite resins and compomer) on their non-carious cervical lesions. The clinical evaluation of the therapeutic success was performed six months and then one year after the day of the placement of restorations using the modified-United States Public Health Service criteria. The following was evaluated retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries.
  
  
  RESULTS
  A statistically significant high percent of restorations/teeth with postoperative sensitivity was found in the group of resin composite restorations after six months. At the end of the evaluation period, that is after one year, there were no statistically significant differences between materials for all evaluated criteria.
  
  
  CONCLUSIONS
  The results of this study show the identical quality of both examined materials one year after the readjustment of non-carious cervical lesions.
