performed via SHPB device to testing dynamic response of human teeth [5], or the dental composites [6], but there very few researches were focused on the dynamic response of porcine dental. We select porcine teeth because of tooth structure is similar to human moreover porcine easier to research and achieved. In this study, both porcine molar teeth and temporary brace materials were studied using SHPB and TKB facilities. 4.2 Specimen Preparation 4.2.1 Teeth Enamel is a hard dental tissue developed from ameloblast cells. Enamel is composed of 96 % inorganic hydroxyl-apatite crystal by weight or more than 86 % hydroxyl-apatite crystal by volume. It also contains organic matrix and a small amount of water; therefore, it is less hydrophilic compared to dentin which has higher water content. Dentin serves as an elastic support for enamel. Unlike enamel, dentin is composed of 70 % inorganic hydroxyl-apatite crystal by weight or 50 % hydroxyl-apatite crystal by volume. Dentin has a higher percentage of organic mineral (18 % by weight or 25 % by volume) Fig. 4.1 Schematic diagram of tooth Fig. 4.2 Temporary braces with teeth model 30 S.J. Chen et al.
