The purpose of this study was to evaluate the application of fiberglass reinforcement method in thermoplastic mouthguard materials to improve flexural properties and adhesive strength. Commonly used two types of commercial mouth guard materials (ethylene-vinyl acetate copolymer-based and polyolefin-based) were reinforced with glass fiber clothes by two-step hot press. Flexural strength and adhesive strength with each base material were examine via three-point bending test and delamination test, respectively. Ethylene-vinyl acetate copolymer-based fiberglass-reinforced material has significantly greater adhesive strength with base material and improvement of flexural properties compared with polyolefin-based material. These results suggest that flexural properties of both conventional commercial mouthguard materials were improved when the glass-fiber-reinforced method was applied to reinforce mouthguard materials, and more, ethylene-vinyl acetate copolymer was more desirable for the base material.

The purpose of this study was to investigate the effects of acetyl tributyl citrate (ATBC) on the mechanical properties, abrasion resistance, and cytotoxicity of a polyurethane-based 3D printing resin for mouthguard applications. The synthesized polycarbonate-based polyurethane acrylate was formulated into digital light processing printing resins with 40 wt% triethylene glycol dimethacrylate, and different percentage of ATBC were added for further characterizations. The mechanical properties and abrasion resistance, ATBC migration, and the cytotoxicity of the resins were evaluated.

Sports-related traumatic dental injuries (TDIs) are a significant global concern, particularly in contact sports, where the risk of orofacial injuries is high. Custom-made sports mouthguards (CSMs) are recognized as the most effective means of preventing these injuries, providing both protection and comfort without impairing athletic performance. Despite their proven benefits, there is no globally standardized approach to mouthguard design, fabrication, or usage, primarily due to varying regulations, awareness levels, and cultural attitudes toward sports safety across different countries.

Background: Traumatic dental injuries with tracheal intubation during general anesthesia are considered one of the most common complications. It is also the primary reason for malpractice legal claims against anesthesiologists according to insurance companies. There is much information regarding the incidence, consequences, and risk factors of traumatic dental injuries during general anesthesia.

A mouthguard electrochemical sensor for salivary glucose detection based on platinum metal hydrogel is proposed in this work. Conventional enzyme-based electrochemical glucose sensors are fraught with issues such as high cost, oxygen dependency, intricate immobilization procedures, and susceptibility to variations in temperature, pH, and so on. The detection of glucose in saliva, as a non-invasive sensing approach, presents a more convenient solution for diabetes monitoring.
