n Journal of Minimum Intervention in Dentistry - In cavities of comparable size and tooth location, does Glass Ionomer Cement (GIC) have a better retention then amalgam? : grey literature




[This document has been captured as part of the JMID-section for Grey-literature. Grey (or gray) literature refers to informally published written material that may be difficult to trace via conventional databases and/or journals as it is not formally published or is not widely accessible. However, Grey literature may still be an important source of information. Examples of grey literature include e.g.: patents, reports, working documents or unpublished manuscripts]

The systematic literature search identified only 1 trial for review and analysis that included 3 separate datasets with relevance to the review question. The overall having higher retention rates than GIC. However, all datasets include low-viscosity GIC, which - in the availability of newer, high-viscosity GIC with stronger regarded to be obsolete. Therefore, the results are insufficient to answer the review question. In addition, the results are further limited by potential selection randomization and unclear allocation concealment. High-quality randomized control trials are needed in order to provide stronger evidence and to answer conclusively. It is recommended that reporting of such future trials should follow the CONSORT statement.
