“…34 It is thought that adding chitosan to HP, which normally degrades on contact with air, stabilized it and prevented it from being released. 47 Also, it is likely that the adhesion of the gel to the tooth surface was increased through the use of chitosan. 48 In light of the above information, we conclude that high efficiency has been achieved with a low concentration of HP.…”

Background: This study aimed to evaluate the effects of an experimental bleaching gel made with TiO 2 and chitosan, along with the Opalescence Boost PF and Philips Zoom bleaching agents, on tooth surface roughness, microhardness and colour. Materials and Methods: The experimental gel, containing 6% hydrogen peroxide (HP), was evaluated against the two existing treatments, which incorporate 40% and 25% HP. For colour evaluation, 36 human premolar teeth were divided into three groups (n = 12). For surface roughness and microhardness evaluation, 72 bovine incisor samples were divided into six groups (n = 12). Data on colour alteration were analysed with the CIEDE2000 formula. Surface roughness was measured using a profilometer, and microhardness was measured with a Vickers hardness tester. ANOVA was used for statistical analysis. Results: There were no statistically significant differences among the groups for surface roughness, microhardness values or colour change after bleaching (P > 0.05). The lowest bleaching efficacy was observed for the 40% HP agent, and the highest efficacy was observed for the 25% HP agent (P < 0.05). Conclusions: An experimental 6% HP gel containing TiO 2 and chitosan provided effective bleaching without adverse effects on tooth surface roughness or microhardness. The use of TiO 2 with chitosan can provide clinicians with positive results.

“…Chitosan was used in many fields as a kind of renewable resources with cellular compatibility and degradability such as cosmic industry, food industry and medicinal industry (Ana, Verica, Sven, & Vladimir, 2015;Inês, Ana, Mariana, Inês, & Celso, 2013;Li, Dou, Fu, & Qin, 2015). Some researchers studied the conjugate of SPI and chitosan and used it as food resources (Yang et al, 2015).…”

“…To prevent this risk, the surfaces of these implants are usually protected by a bioactive coating [2][3][4][5][6]. Among these coating materials, chitosan possesses outstanding properties, such as non-toxicity, biodegradability, biocompatibility, and antimicrobial [7][8][9][10][11]. As one of the most abundant polysaccharides in crustacean exoskeletons and is commonly found in the cell walls of several fungi and algae, chitosan consists of a large number of hydroxy and amino groups [12].…”

We develop a novel chitosan-citric acid film (abbreviated as CS-CA) suitable for biomedical applications in this study. In this CS-CA film, the citric acid, which is a harmless organic acid has been extensively investigated as a modifying agent on carbohydrate polymers, was cross-linked by 1-Ethyl-3-(3-dimethyl aminopropyl) carbodiimide (EDC) and N-hydroxysuccinimide (NHS) onto the surface of chitosan (CS) film. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) confirms the graft copolymerization of the modified chitosan film (CS-CA). Surface wettability, moisturizing performance, the capacity of mineralization in vitro and biocompatibility of the films were characterized. After modification, this CS-CA film has good hydrophilicity. It is very evident that the citric acid grafting treatment significantly promotes the biomineralization of the chitosan based substrates. Cell experiments show that the MC3T3-E1 osteoblasts can adhere and proliferate well on the surface of CS-CA film. This CS-CA film, which can be prepared in large quantities and at low cost, should have potential application in bone tissue engineering.
