Abstract :

Background:The addition of filler 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 a filler for dental material such as composite resin.  The calcite synthesized HA is the HA produced of calcite minerals that came from many Indonesian mining. Purpose:The aim of this  study is to evaluate the effect of the different concentration of the calcite synthesized HA as the filler of the epoxy-resin-based root  canal sealer on the physical properties such as its contact angle, the film thickness and the microhardness. Methods: The crystal of the  calcite synthesized hydroxyapatite with the size between 77.721-88.710 nm and the ratio of Ca/P 1.6886 were synthesized at Ceramic  Laboratory, Mechanical Engineering, Universitas Gadjah Mada using wet method of hydrothermal microwave. The powder of the  epoxy- resin were prepared by added the synthesized hydroxyapatite crystal in five different weight ratios (e.g: HA-10%, HA-20%,  HA-30%, HA-40% and HA-50%). Each of these was mixed with the paste of 3:1 ratio using spatula on a glassplate until homogen and  then measuring the contact angle and the film thickness. The Microhardness test was conducted after the mixture of the experimental sealer was store for 24 h at 37o C to reach the perfect polimerization. results:All of the contact angle were <90o and were not  significantly different to each other (p= 0.510). All groups had a film thickness in accordance with ISO 6876 (<50 um) and with no  statistical difference (p= 0.858). In the HA of 10%, 20%, 30% seen that the microhardness were increased, while in the HA-50% was  decreased and in the HA-40% has the same microhardness to the control groups (HA-0%). Conclusion:Calcite synthesized HA as  the filler not affect contact angle and film thickness of the sealer. Microhardness of the epoxy-resin based sealer could be increased  using maximum 30% of the calcite synthesized HA as the filler.
