The self-completion questionnaire sought information concerning each athlete’s use of mouthguards and any history of oral trauma while participating in sports. Positive responses to previous trauma were qualified concerning the type and location of the injury, the sport during which the injury occurred, and whether the athlete was wearing a mouthguard at the time of injury.
Descriptive statistics, such as mean age and standard deviation, were done. The data was also analyzed using chi-square statistic for significance of observed differences and test of association, accepting p<0.05 as significant. All the analyses were done using the statistical package for social sciences (SPSS for Windows). cialis professional
