In geriatric patients, will the clinical performance of nano hydroxyapatite reinforced glass ionomer be better than conventional glass ionomer cement in treatment of root caries lesions over one year follow up?

Glass carbomers are commercialized under the name of GCP Glass Fill, this material may be an interesting subject of research, certainly its bioactive properties as the manufacturer claims this material to have remineralizing properties. If this is the case, GCP Glass Fill could be an interesting reference material for further bioactivity studies
