Abstract
dc.description.abstract
This study investigated by means of a systematic review of the literature and meta-analysis the impact of
physical and/or chemical surface treatments on the repair bond strength of methacrylate-based dental
composites. Three international databases (Medline/PubMed, Scopus, and Web of Science) were searched. Studies that evaluated the repair bond strength of aged control composites (untreated or treated
with abrasives) and aged composites subjected to surface treatments before repair (physical, chemical, or
physical þ chemical) were included. In total, 777 articles were found, 129 were selected for full-text
reading, and 15 studies were included in the qualitative and quantitative synthesis. Meta-analyses were
conducted using random effects model to calculate pooled mean differences between control and treated
composites, according to the different groups of surface treatments. Statistical heterogeneity was
assessed using the Cochrane Q statistic and I
2 test. Risk of bias of all included studies was assessed.
Application of chemical or physical þ chemical surface treatments of aged composites was shown to
generally improve their repair bond strengths. Silane coupling agents appeared to have a minor role as
compared to adhesive agents in improving repair potential. Airborne-particle abrasion alone was found
not to contribute significantly to the repair bond strengths. High heterogeneity was observed in most
statistical analyses; the analysis of risk of bias also indicated potential problems associated with
reporting in the studies. Therefore, suggestions for future in vitro studies on the repair bond strength of
dental composites are given.
