57 Introduction The necessity to bond orthodontic brackets onto precious metals or their alloys has recently increased, especially in adult patients [1]. In the engineering fields, various methods have been developed to improve bond strength between metal surfaces and polymer adhesives. Clinically, pretreatment of metal surfaces are performed using a few procedures, e.g. abrasion [1-4] and primer methods preceded by mechanical cleaning [2,4-9]. Physicochemical alteration by water vapor and organic matter directly occurs after cleaning because of the incommensurably high surface energy of metals. A highly effective, simple, and time-effective pretreatment of primers is thus warranted. Plasma is a state of matter that consists of electrons, ions, free radical, and electronically excited atoms and molecules. In the past several years, there have been extensive efforts in apEvaluation of a Gliding Arc Discharge Non-thermal Atmospheric Pressure Plasma Device for Orthodontic Bonding

63 Introduction Bone defects attributed to serious periodontitis, trauma, and injury are commonly encountered in the fields of dentistry, craniofacial surgery, and orthopedics. Although autogenous bone grafting is still considered the gold standard for treatment, this process has several drawbacks, such as the requirement of a second surgery and the limited availability of collectable bone [1]. Artificial bone grafts are thought to be promising alternatives to autogenous bone grafts. Several calcium phosphate (CaP)-based biomaterials, such as hydroxyapatite (HA), tricalcium phosphate (TCP), and octacalcium phosphate (OCP), have been intensively investigated for use as artificial bone because, under appropriate conditions, these materials show excellent biocompatibility and bioactivity [2, 3]. High-temperature TCP, known as alpha-tricalcium phosphate (-TCP), is often prepared by the sintering of amorphous precursors with the proper composition [4]. Its calciumto-phosphate ratio is theoretically 1.50. In general, -TCP dissolves more easily than OCP, -TCP, and HA under neutral pH conditions [4]. Furthermore, -TCP converts to apatite in aqueous solution over time [5], to lowComparison of the Bone Forming Ability of Different Sized-alpha Tricalcium Phosphate Granules using a Critical Size Defect Model of the Mouse Calvaria

72 Introduction A room temperature ionic liquid (RTIL) is an organic salt that is liquid at room temperature and has specific physical properties such as noncombustibility, no vapor pressure, high heat resistance, and high ionic conductivity. These unique properties have led many researchers to use RTILs in various fields, including electronics, chemistry, analysis, and catalysis [1-6]. Kuwabata et al. have reported the successful use of an RTIL for the electronic pretreatment of biological samples, such as insects, flowers, tissues, pollen, and cells, for scanning electron microscopy (SEM). As RTILs have high electrical conductivity and no or very low vapor pressure, they can maintain their liquid state even in vacuum, making them suitable for use inside an SEM sample chamber, and also facilitate clear Electroconductive Pretreatment of Several Types of Non-conductive Wet Biological Samples for SEM using a Room Temperature Ionic Liquid: Simple and Rapid Conductive Preparation
