Gaps in current Glass-ionomer cement research

Systematic reviews are defined, according to the Cochrane collaboration, as scientific literature reviews aimed at answering clearly formulated questions through use of systematic and explicit methods for identifying, selecting and critically appraising relevant research, and for collecting andanalysing data from the literature included in the review. Through this process, systematic reviews provide a unique opportunity for also identifying gaps in the currently available research on a particular topic and providing recommendations for addressing these. In order for such objective to become part and parcel of the regular systematic review process, it has been suggested that the identification of research gaps should follow a systematic approach that is based on widely accepted elements and provides transparent and reproducible results.
