title: Qualities of the restorations of glass-ionomer cement of caries and non-caries lesions of the dental necks after a two-year observation period.
abstract: OBJECTIVE
  The aim of the study was to follow up the quality change of the restorations with the glass-ionomer cement "Vitremer" 3M.
  
  
  METHODS
  A total of 97 restorations were performed in the region of the dental necks. The diagnoses were as follows: caries cervicalis--55; caries radicis dentis--9; usura cervicalis--9; erosio dentis--24. The assessment of the restorations was performed immediately after fixing and two years later according to the criteria of G Ryge.
  
  
  RESULTS
  The results showed good adhesion of the restorative material to the dental tissues, absence of secondary caries and changes in the marginal adaptation and considerable darkening of the colour.
  
  
  CONCLUSIONS
  The glass-ionomer cement "Vitremer" 3M is suitable restorative material for the cervical region, especially in individuals exhibiting high caries activity.
