Abstract

Backgrounds: Restorative dental material is one of the forensic experts directory assistance to determining the identity of the unknown victim who in burn condition. Determining the identity can be done through changes dimensions. Changes dimensions can be look of reduced weight and discoloration on the restorationat high temperatures. Composite resin restorations is one materials that is mostly used because it has mechanical characteristic, aesthetic and physical well compared to other restorative materials.Objective: To identify the changes ofdimensions such as the weight reduction and the changes ofcolor between nanofiller composite resin with microhybrid composite resin which is heated at high temperatures. Method and Material: The material used is nanofiller composite resin andmicrohybrid composite resin. The stageof thetreatment is done by heating the composite resin at three temperatures: 319oC, 412oC, 800oC then look at the changes ofcolor and the weight reduction.Results and Conclusion: The results of two way ANOVA test and Post Hoc LSD test showed a significant differences with p <0.05. Theconclusion is there are physical changes such as discoloration and weight reductionof the composite resin which is heated at high temperatures.Keywords: Nanofiler composite resin,Microhybrid composite resin,and heated at high temperature.

The study determine the differences of maxillary first molar and mandibular caninus tooth size between male and female student in Faculty of Dentistry University of Jember. The sample of this study consisted of 34 tooth models of female and 6 tooth models of male that measured in mesiodistal and bucolingual width of maxillary first molar and mandibular caninus with a digital caliper. Data were analyzed using Independent T-test. There were significant differences (p ≤ 0,05) of maxillary first molar and mandibular caninus size between male and female. Mesiodistal and bucolingual width of maxillary first molar respectively are 10.64 mm, 11.90 mm in males, and 10.16 mm, 11.16 mm in females. The mesiodistal and bucolingual width of mandibular caninus are 7.13 mm, 7.85 mm in males, and 6.66 mm, 7.08 mm in females. It can be concluded that there was a difference in size of maxillary first molar and mandibular caninus between male and female.
