Data forTMJ disorders prevalence and awareness of appropriate clinical practices, among Al-Madinah community in Saudi Arabia.sav

In order to estimate Fonseca's Anamnestic Index, a modified Fonseca's questionnaire was utilized. The questionnaire included questions about participant’s demographic data, if the participant thought he\she is suffering from TMDs, and whom to seek for a treatment if he/she needed to. These questions were followed by 10 questions of Fonseca's questionnaire with three points scale, and it was distributed to patients in an Arabic version. For each question, the participants were instructed that just one answer should be marked: "yes" (10 points), "no" (0 points), and "maybe" (5 points). Based on the sum of their points, the individuals were classified as TMD free (0–15), mild TMD (20–40), moderate TMD (45–60), and severe TMD (70–100). The FAI has been usually applied in Brazilian studies to measure the severity of TMDs[9,14] . The data was evaluated using a social science statistical software (SPSS). Means, standard deviation, and percentages were used to show descriptive data. It was followed by Chi-square test for nominal outcomes and Student's t-test for continuous study variables. Significance level was set at P value of 0.05.
