Several methods have been used to measure the impact force absorption capacities of mouthguard materials; however, the relationships among these measurement systems have not been clearly determined. The purpose of the present study was to evaluate the impact force-absorbing capability of materials using a drop-ball system with film sensors and load cells to clarify the relationship between these two sensor systems.

BACKGROUND/AIM: Mouthguards are crucial for protecting athletes against orofacial injuries, yet concerns persist regarding their potential impact on oral functions. This study aimed to investigate the effects of sports mouthguards on oral functions and speech over time.
MATERIAL AND METHODS: Thirty national rugby players received custom-fitted mouthguards. Questionnaire responses and speech recordings were collected before mouthguard use and at various intervals after using mouthguards: immediately, 1 week, 2 month, and 6 months. Spectrographic analysis was performed to measure voice onset time (VOT) for /p, b, t, d/ phonemes. Questionnaire responses were assessed with Friedman's test, while VOT changes were examined using one-way repeated measure analysis of variance.
RESULTS: Compliance with mouthguard use improved during training and competitions, with consistent wear reported during matches. Over time, speaking difficulties and lisping decreased significantly (p Mouth dryness reduced steadily, with no occurrences reported by all players by the end of the study. None of the participants reported bad breath, ulcers, or redness in the mouth. VOT changed immediately after wearing mouthguards (p

To assess their awareness and usage of mouthguard and occurrence of sports-related oral injuries in athletes who involve in various sports activities in Kota Bharu. A cross-sectional study was carried out among 180 athletes aged 12 to 27 years. A structured interviewer-guided questionnaire was used to determine the prevalence of oral injuries sustained during sport activities, the use of mouthguard as well as the athletes' awareness of mouthguard use. The respondents consisted of 107 males (59.5%) and 73 females (40.5%) with a mean age of 16.7 years (SD 5.53). There were 60 (22.2%) athletes who had one or more types of sports-related oral injuries sustained. Laceration of lips, tongue and gums were the most frequent injuries (57.5%) while loosening of teeth and fracture of teeth sustained in 12.5% and 10.0% of athletes respectively. Malay traditional martial arts silat athletes, 17(68.0%) experienced the highest oral injuries among athletes. The prevalence of oral injuries was significantly different between ball sports, martial arts and other non-contact sports (p=0.002). Sixty-one athletes (33.9%) reported that they were aware of mouthguard; however none of the athletes used the mouthguards during their sports activities. Malay traditional martial arts silat was the most common susceptible to sustain oral injuries. None of the athletes were wearing mouthguard. Education on prevention of orofacial trauma should be given to the coaches and athletes. Wearing of mouthguard during sport activities should be compulsory during practice and competition events.

Participation in contact sports has been shown to carry a considerable risk of sustaining dental injuries. It is important for athletes to use available preventive gear to protect themselves from these injuries. Aim of the study: To assess the knowledge, habit and preferences of using mouthguards among university athletes. Materials and Method: Self-administered questionnaires, consisting of Part A - Age, gender, type of sporting activities, total hours dedicated to sports training, level of sports representation; Part B - Awareness of risk of dental injuries, knowledge on mouthguards such as definition of a mouthguard, role of mouthguard, use of mouthguards and reasons for not wearing mouthguards; and Part C — Experience of sustaining dental injuries during sports activities, were distributed. Athletes who were university students over 18 years and under 30 years of age and athletes who claimed to know about mouthguards were included in the study. Results: Data of a total of 225 respondents were analysed, consisting of 68% (n=154) male and 32% female (n=71) with the mean age of 21 years old. Only 46% (n=104) knew exactly about mouthguards and its role in the prevention of dental injuries during sports. Thirty seven percent of them (n=84) have used mouthguards and they were mostly in the martial arts group. The mouthguards were usually provided by the management team (62%). Forty percent of the respondents (n=91) claimed to have sustained dental injuries while playing sports and the injuries occurred more frequently in hockey (65.3%), basketball (60%) and soccer (45.2%). Conclusions: The incidence of dental trauma in contact sports shows that the awareness and use of mouthguards must be intensified. Awareness campaigns focusing on dental trauma should be organized to improve the knowledge of athletes.
