Abstract
The purpose of this
practice-based study was to compare the clinical performance of a new
universal composite resin material (Z250) used for Class III and V
cavities in anterior teeth. Restorative materials (Z250 and Z100; 3 M
ESPE) placed by six operators were used for a total of 150 restorations
during the 6-month enrollment period. After 1 year, 141 restorations (76
Z250 and 66 Z100) were available and evaluated for overall quality,
color match, marginal adaptation, surface appearance and the presence of
secondary caries, using modified USPHS criteria. The overall quality
was excellent for both materials and no significant changes were noted
during the follow-up. None of the scores between the two materials were
statistically significant. Major changes were seen in color match and
surface appearance. At baseline, the color match of 71% of Z250 and 62%
of Z100 was rated as Alfa, after 1 year the figures were 60 and 65%.
Regarding surface appearance, 97% of the Z250 were rated Alfa at
baseline, whereas at 1 year the figure was 76%. For Z100, the scores
were 94 and 79%, respectively. After 1 year, the clinical performance of
Z250 restorative composite resin was clinically acceptable and similar
to that of Z100.
