Abstract
Statement of problem
Although the clinical use of self-adhesive flowable composite resins is convenient,
the decision to use flowable or conventional composite resin remains controversial.
Purpose
The purpose of this systematic review and meta-analysis was to assess the in vitro
bond strength of self-adhesive flowable composite resins to enamel or dentin compared
with conventional composite resins using etch-and-rinse or self-etch adhesive systems.
Material and methods
Two independent reviewers performed searches in the PubMed (MEDLINE), Cochrane Wiley,
Web of Science, Scopus, and Google Scholar databases for studies reporting on the
bond strength of self-adhesive flowable and conventional composite resins to enamel
and dentin published from January 2010 up to September 2020. A meta-analysis software
program was used for the meta-analysis. Comparisons were conducted using standardized
mean differences considering the random-effects model (α=.05).
Results
Twenty-two studies were considered for the meta-analysis. Immediate and long-term
bond strength to enamel was improved when a conventional composite resin was used
in combination with an adhesive system (P<.001). Bond strength to dentin was improved by using an adhesive system in combination
with a conventional composite resin (P<.001).
Conclusions
The bond strength of self-adhesive flowable composite resins is lower than that of
conventional composite resins, indicating limited ability to bond to enamel and dentin.
