Clinical Performance of Two Different Restorative Materials in Restoring Class II Cavities of Primary Molars

The aim of the present study is to assess Flowable Giomer Beautifil Flow Plus X (Shofu Dental Corporation, Japan) and Glass-hybrid-added HVGIC, Equia Forte (GC Corporation, Tokyo, Japan) in class II cavities of primary molars regarding the following objectives: The primary objective To evaluate and compare the clinical performance of Flowable Giomer Beautifil Flow Plus X (Shofu Dental Corporation, Japan) and Glass-hybrid-added HVGIC, Equia Forte (GC Corporation, Tokyo, Japan) in restoring class II cavities of primary molars after 3,6, and 12 months. The secondary objective To assess the effect of different independent variables on the treatment outcome of the experimental restorative materials. Research question: Is there a difference in the clinical performance between flowable giomers and highly viscous glass ionomer in restoring class II cavities of primary molars? Null Hypothesis There is no difference in the clinical performance between Flowable Giomer Beautifil Flow Plus X (Shofu Dental Corporation, Japan) and Glass-hybrid-added HVGIC, Equia Forte (GC Corporation, Tokyo, Japan) after one year of follow up.
