Characterization of Dental Lab Putty Materials Components Made from Glutinous Rice

Abstract

This paper presents the preliminary results from the experiment of making lab putty from glutinous rice. The experiment aims to use natural, safe, and cheap ingredients to synthesis reliable products of making direct palatal matrix index of class IV dental composite restoration, by characterizing the particle morphology and how each element binds to one another as well as its compositions. Hand manipulation on lab putty was carried out on two different samples accompanied by two fabricated samples with size of 4x2 cm. Particle morphology was characterized with JEOL Scanning Electron Microscope (SEM) and sample composition confirmed using Electron Dispersive Spectroscopy (EDS). The SEM result revealed that sample A shows smooth morphology from well-mixed glutinous rice tend bind with silicon rubber paste and bovine gelatin. Meanwhile, sample B shows hexagonal and polyhedral morphology that appears to be similar agglomerated form to the sample that marketed available (sample C and D). From the EDS result, it can be confirmed that compositionally, the four samples are similar. To conclude, lab putty made from glutinous rice can be considered as an option of low cost and safe palatal matrix index for class IV composite restoration. Better development of mechanical properties shall be conducted by future research.
