Sponsor's own description
Participation in contact sports is linked to an increased risk of dental injuries. To reduce the risk and severity of sports-related dental injuries, mouthguards are often recommended to be worn during training and competition. However, athletes often complain that they cannot talk properly when using mouthguards. It is hypothesized that speech performance differs when using different types of mouthguards. A group of female national rugby players will be asked to pronounce four Malay words with plosive sounds (/p/, /b/, /d/ and /t/) repeatedly in three conditions: (i) when not using any mouthguard, (ii) when using 'boil and bite' mouthguard, and (iii) when using custom-fitted mouthguard. The sounds will be recorded for spectrographic analysis. The difference in mean voice onset time between conditions will be assessed.
