GIC is widely used as a dental material, due to its ease of use, low coefficient of thermal expansion, good biocompatibility with bone pulp tissue, and long-term bonding to tooth surfaces and metals [2,3]. In addition, its unique fluoride (F) ion release characteristics have anticaries, antimicrobial and remineralization effects [4,5]. However, its current uses are limited because of its inadequate strength. Several researchers have attempted to overcome these poor mechanical properties by adding reinforcements, but sufficient improvements in mechanical and chemical properties have not yet been achieved [6-8]. As hydroxyapatite (HAp) has great biocompatibility and a composition similar to apatite in the human tooth, Nicholson et al. [9] first attempted to incorporate HAp into GIC prepared from oxide glass and F glass and concluded that the properties of GIC were not affected by the presence of HAp. However, other researchers reported that addition of HAp into commercially prepared GICs improved the mechanical properties [10,11]. In our previous studies, it was demonstrated that the addition of HAp particles was able to enhance both the mechanical and chemical properties of a conventional GIC used for dental restoration, Fuji IX GP (IX-GP; GC Corp., Tokyo, Japan) [12-14]. Moreover, we confirmed that the most suitable HAp for incorporation into GIC was porous HAp with a high specific surface area [14]. However, further investigations are necessary to clarify the mechanisms responsible for the improvement in mechanical and chemical properties by adding HAp to GIC.

The demands for tooth whitening have also markedly increased. However, hydrogen peroxide (H2O2) is used at a high concentration (30-35%) in the office bleaching method, which raises concerns about hyperesthesia [1, 2] and its adverse effects on dental hard and periodontal tissues [3-7]. To minimize these adverse effects, titanium dioxide (TiO2), used in white pigments, cosmetics, paint, and food additives, has been applied to tooth whitening [8-10]. TiO2 is less expensive because it is abundant in nature, and is safe for the human body because it is chemically stable. TiO2, used as a photocatalyst, causes a strong redox reaction through holes and electrons generated by light absorption. TiO2 becomes super-hydrophilic when coated as a membrane. In the presence of water, multiple types of radicals are known to be generated by the redox power of a photocatalyst [11]. TiO2 absorbs light above band gap energy (approximately 3.1 eV), and electrons are excited to the conduction band. The excited electrons reduce oxygen, generating superoxide radicals, such as O2 •.
