Survival of direct resin restorations in posterior teeth within a 19-year period (1996–2015): A meta-analysis of prospective studies. Issue 8 (August 2015) - Beck, F.
Highlights 88 prospective, clinical trials (1996–2015) were analyzed in terms of survival of posterior composite restorations. Significant findings were only observed for short-term studies and by including all studies (short- and long-term studies). The observation period, the recall rate, the ratio of Class I/II fillings and the number of restorations/patients had a significant influence on the overall failure rate when including all studies (short- and long-term). No influence of operator status, isolation method or bonding systems on the overall failure rate was found. In this study a trend of excluding patients at-risk (e.g. high caries activity) and including patients with good oral hygiene was identified, which produces more favorable results.
