Introduction. Regular use of mouthguards requires proper arrangements for their disinfection and sanitization. Incorrect or infrequent hygiene procedures may lead to inflammatory infection in the oral cavity. Prevention measures also involve periodical replacement of mouthguards due to the growth of microorganisms on their surface, along with increasing porosity on use. Buying a new protective occlusal splint is also recommended in the event of an inflammatory lesion in the mouth, and after infection of the respiratory system. Aim of the study. To assess usage and hygiene maintenance of elastic mouthguards by athletes practicing various sports disciplines. Methods. A group of 1279 mouthguard users were surveyed, including questions about demographic background of participants, hygiene habits and storage of protective splints. Statistical analysis of the results was performed; the level of statistical significance was established at p < 0.05. Results. It was revealed that 5% of the interviewed athletes (60 individuals) do not cleanse their mouthguards. Most of the surveyed participants (85.5%) rinse the splint with water after wearing it. Only every fifth athlete replaces the mouthguard at regular intervals, regardless of its condition; half of the respondents do it when it is completely deformed, and one-third do it after loss of smoothness of its surface. About 20% of athletes have never replaced their protective occlusal splint. All results showed statistical significance. Conclusions. Athletes’ awareness of proper usage, storage and sanitization of mouthguards is not sufficient.
Introduction. The application of flexible occlusal splints in therapy of the stomatognatic system is recommended for short-term use only because of the risk of muscle overloading or occlusal plane disorders. Mouthguards used in prevention of head and mouth injuries are a modification of occlusal splints. They are made of flexible material with properties enabling absorption of impact energy. Due to regular use during trainings and competitions they may have an impact on the incidence of stomatognatic system ailments. Aim of the study. To assess the factors determining the choice of a mouthguard type and its influence on the stomatognatic system. Material and methods. A survey was conducted among 1279 mouthguard users to collect demographic data and information concerning mouthguards on the occurrence of problems arising from their use including pain in the area of the stomatognatic system. Statistical analysis of the results was also performed. Results. 36% athletes with standard mouthguards, 37% with “boil and bite” and 44% with custom-made ones have a tendency towards strong clenching of dental arches. Participants using a custom-made mouthguard reported chewing muscle fatigue more often than the users of the standard and “boil and bite” type, but they did not report any pain located in the area of temporomandibular joint. People experiencing fatigue and with a strong clenching of dental arches tendency significantly more often choose a type considering its retention ability, whereas pain in the temporomandibular joint area does not influence their preferences. Athletes, who declare teeth clenching, more frequently indicate the retention factor as important. Conclusion. It is necessary to conduct further research on the use of mouthguards considering their impact on the stomatognatic system.
Badanie elektromiograficzne (EMG), polegające na pomiarze sygnału elektrycznego wytworzonego przez mięsień w trakcie skurczu oraz ocenie czasu trwania potencjału, jego amplitudy i kształtu, znajduje zastosowanie w stomatologii (1). Poddawany analizie jest zarówno zapis spoczynkowy, jak i wysiłkowy jednostki motorycznej. Podczas niewielkiego i umiarkowanego wysiłku zdrowego mięśnia rejestrowane są pojedyncze potencjały jednostki ruchowej. Aktywność mechaniczną mięśnia poprzedza rejestracja aktywności elektrycznejjest to opóźnienie elektromechaniczne (EMD), które zależy m.in. od temperatury i struktury Streszczenie Elektromiografia powierzchniowa umożliwia w nieinwazyjny i niebolesny sposób pomiar potencjału elektrycznego mięśni. W stomatologii znajduje zastosowanie zarówno w diagnostyce, ocenie przebiegu leczenia, jak i badaniach epidemiologicznych. Metoda ta często wykorzystywana jest w badaniach dotyczących bruksizmu i dysfunkcji narządu żucia oraz kontroli leczenia ortodontycznego i protetycznego. Celem pracy było przedstawienie głównych zastosowań elektromiografii powierzchniowej w stomatologii.
