Are there universal restorative composites for anterior and posterior teeth?

In Press, Uncorrected Proof Abstract
Objective
This
retrospective, longitudinal clinical study investigated the longevity
up to 20 years of posterior restorations placed with 3 universal
composites (Charisma, Herculite XR, Z100) and of anterior restorations
placed with 2 universal composites (Charisma, Herculite XR).
Methods
Records
from 90 patients were retrieved from a private practice (374 posterior,
219 anterior restorations). Clinical evaluation was performed by the
FDI criteria. Survival analysis was assessed using Kaplan–Meier method
and Log-Rank test, and factors associated with failure by multivariate
Cox regression with shared frailty.
Results
In
the first 10 years, almost 95% of the restorations were satisfactory,
showing increased failure thereafter. Charisma showed the most failures
in anterior and posterior areas. Annual failure rates varied between
0.3% and 2.5%, with slightly better performance for anterior
restorations. Fracture (posterior) and aesthetics (anterior) were the
main reasons for failure.
Clinical significance
Differences
were observed between restorative materials with different properties,
but these became apparent only after more than 10 years of clinical
service. The present study provides evidence that in a patient group
with low caries risk, anterior and posterior restorations placed with
universal composites may have excellent long-term clinical performance.
