Material and Methods: Seventy-two non-professional players of wind instruments (instrument group) (mean(SD), 20.0(1.1) y; 42 women) and 66 non-players (control group) (22.0(2.6) y; 45 women) participated in this study. Factors were investigated using questionnaires (a screening questionnaire for TMD, instrument playing habits, years of experience, and time played per day). Result: The prevalence of a high risk of TMD was not significantly different between the instrument group (29.2%) and control group (21.2%). In the instrument group, the frequency of subjects who felt mouthpiece pressure in the high risk of TMD group (47.6%) was significantly greater than that in the low risk of TMD group (21.6%). Mouthpiece pressure was found to be a significant factor contributing to a high risk of TMD (odds ratio, 3.31; 95% CI, 1.12–9.79). Conclusion: This study suggests that pressure from the mouthpiece was one of the contributing factors related to a high risk of TMD in non-professional wind instrument players. 08 22 2016 411 416 TODENTJ-10-411 1 10.2174/crossmark_policy opendentistryjournal.com benthamopen.com true Peer Reviewed Single blind Checked with iThenticate 2015-11-11 2016-6-14 2016-7-13 2016-08-22 https://creativecommons.org/licenses/by-nc/4.0/legalcode 10.2174/1874210601610010411 1553506546 https://opendentistryjournal.com/VOLUME/10/PAGE/411/ https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.pdf https://opendentistryjournal.com/contents/volumes/V10/TODENTJ-10-411/TODENTJ-10-411.xml Okeson JP.
