17 pro- and retrospective studies were included in this anterior composite restoration performance. While low annual failure rates from 0 – 4.1% were found, there is a need for well-designed clinical trials to evaluate the longevity of anterior composite restorations and investigate the specific factors associated with failure.

It included a small number of systematic reviews, which were of limited quality and based on a small number of small studies. While good 5 year survival rates were found, the quality of the evidence means that the findings should be interpreted cautiously.
