Evaluation of compressive strength, disintegration, fluoride release, pH, radiopacity and antimicrobial properties of temporary cement prepared with fluoride compounds and linoleic acid

In order to choose right dental material, dentist must realize physical, chemical and biological properties of cements and also caries preventive property. The aim of this study is to formulate a cement having ideal properties and to investigate compressive strenght, disintegration, fluoride release, pH, radiopacity and antimicrobial properties of formulated five different cements that contain linoleic acid, zinc oxide, zeolite, titanium dioxide, calcium hydroxide, sodium fluorid, stannous fluorid, titanium tetrafluorid and amonium fluorid and zinc oxide eugenol as control group. Standart disks were prepared. The specimens maintained in incubator for 24 hours, and than the compressive load was applied. The specimens prepared for disintegration were maintained in distilled water for 24 hours in incubator, afterwards they were stored in desiccator for 24 hours. The fluoride release of specimens were measured at 1., 2., 3., 7., 14., 21., 28., 35. and 42. days. The specimens were measured to determine pH at 5., 10., 30., 60., 120. minutes, and 24., 48. hours. The radiopacity of specimens measured with optic-densitometer. To determine antimicrobial effect S.mutans ATCC 25175 and L.casei ATCC 4646 were used. Control group showed significantly higher compressive strenght and disintegration than other groups. N group showed highest fluoride release at all days. pH values of all groups showed significant difference between each other. Control group showed significantly higher radiopacity than other groups. On S.mutans N group; on L.casei control group showed the most antimicrobial effect.
