Abstract
dc.description.abstract
Purpose: The objective of this study was to
clinically evaluate sealed composite restorations
after 10 years and compare their behavior
with respect to controls.
Methods and Materials: The cohort consisted
of 20 patients aged 18 to 80 years with 80
composite restorations. All participants in the
sealing and no-treatment groups presented with clinical features for the marginal adaptation
that deviated from the ideal and were
rated Bravo (United States Public Health Service
criteria). Composites with Alfa values for
the marginal adaptation were used as the
positive control.
Results: The marginal adaptation behavior was
similar between the sealing and control (+)
groups, with a high frequency of Bravo values in the 10th year (80% and 51%, respectively).
Most of the no-treatment (-) group maintained
the Bravo values (91%) for 10 years, although
some restorations (9%) progressed to Charlie
values. The anatomy parameter differed significantly
between the first and 10th years, with
deterioration in all three groups (p,0.05). The
secondary caries parameter had a similar behavior
in the three groups (p.0.05).
Conclusions: Sealing the margins of the composite
resin restorations had no significant
effect compared with the control groups, under
the conditions of this study. Sealing the
restorations substantially improved the marginal
staining and marginal adaptation parameters,
although by the tenth year they were
similar to the group without intervention.
