<br/><br/> This study was conducted to evaluate and compare the efficacy of composite releasing ca and po4 ions versus conventional glass ionomer,  and resin-modified glass ionomer regarding,: remineralization capacity andmicroleakagein permanentpremolars ( in vitro study).A total number of 34 teeth. According to the circumstances ofthis study, it was concluded thatTetra calcium phosphate composite are more effective againstmicroleakageand further decaythan other restorations by enhance remineralization capacity
