SIFAT FISIK HIDROKSIAPATIT SINTESIS KALSIT SEBAGAI BAHAN PENGISI PADA SEALER SALURAN AKAR RESIN EPOXY (PHYSICAL PROPERTIES OF CALCITE SYNTHESIZED HYDROXYAPATITE AS THE FILLER OF EPOXY-RESIN-BASED ROOT CANAL SEALER)

Background: The filler addition to resin based sealers will enhance the physical properties of the polymer.Because of its biological properties, the synthetic hydroxyapatite (HA) has been proposed as filler for dental material such as composite resin.The calcite synthesized HA is the HA produced of calcite minerals that came from many Indonesian mi
