Introduction. The aim of this one-year prospective clinical study was to
evaluate the treatment results of compomer restorations (Dyract? eXtra/
Dentsply/De Trey, Konstanz, Germany) with a single step self-etching dental
adhesive (Xeno? III Dentsply/De Trey, Konstanz, Germany) used for restoring
class V lesions (non-carious and primary carious cervical lesions). Material
and Methods. A total number of 62 class V restorations (n = 62) were placed
by one dentist in 30 patients on incisors, canines and premolars. The
fillings were placed due to different indications: non-carious cervical
defects (n = 32) and primary carious lesions (n = 30). The restorations were
evaluated by a single-blind design, according to the Modified United States
Public Health Service system 6 and 12 months following the placement. The
following were evaluated: retention, marginal integrity, marginal
discoloration, wear, postoperative sensitivity and secondary caries. The
statistical analysis compared the ratings of each criteria between materials
using the Pearson chi-square or Fisher?s exact test at a level of
significance of 5% (p<0.05). Results. Two restorations of the non-carious
lesion group were lost after 6 months, and after 12 months one restoration
was lost in the group of primary carious lesions. There were no statistically
significant differences between restorations for all evaluated criteria in
both groups. Conclusion. The compomer restorations in combination with a
single step self-etching dental adhesive showed acceptable clinical
performance in Class V lesions after one year of clinical service.
