Abstract

The current production technology of dental cement material is growing rapidly compared to 50 years ago. Cement as dental restoration material must be elastic and have a low conductivity property. There are four kinds of dental cement commonly used in dentistry, namely zinc phosphate cement, polycarboxylate cement, glass ionomer cement, and zinc oxide and eugenol cement. There is no study about physical and mechanical properties based on in-vivo condition. This study aims to know the physical and mechanical properties of dental cement, by the in-vivo approach and using rabbit as an experimental object. Dental cements used in this research were zinc phosphate cement (ZPC), polycarboxylate cement (PC), glass ionomer cement (GIC), and zinc oxide and eugenol cement (ZOEC). The method of this study was the preparation of tools, materials and experimental animals. We used six male - 5 months in age - rabbits. Before being treated (fill-teeth material insertion), the rabbits were anesthetized by an anaesthetist from the Animal Hospital, Faculty of Veterinary Medicine, Universitas Airlangga. Then the rabbit teeth were drilled and formed to become box cavity. Information which can be obtained from this in-vivo experiment is its physical and mechanical properties i.e. compressive strength, tensile strength, and microstructure of dental cement. Based on the physical and mechanical characterization value, the best compressive strength was 101.888 MPa and refers to zinc phosphate cement and the best tensile strength value was glass ionomer cement with 6.555 MPa. The morphological features, mainly surface structure of dental cement, showed less well sealed for zinc phosphate cement, strongly bonded with teeth for polycarboxylate cement, there were lumps of unreacted powder particles for glass ionomer cement and there was a very hard lump formed for zinc oxide and eugenol cement.
