This cross-sectional online survey investigates the prevalence of orofacial pain, sleep-related problems, and oral health-related quality of life (OHRQoL) among adult musicians who play in German amateur orchestras. Participants complete a single, anonymous, approximately 10-minute questionnaire covering demographic data, orofacial pain, sleep bruxism, perceived stress, sleep quality, and the German short version of the Oral Health Impact Profile (OHIP-14). The study examines whether these outcomes differ between instrument groups (woodwind, brass, string, percussion, and other instruments). The primary hypothesis is that players of wind instruments (woodwind and brass) more frequently report orofacial pain and experience a different OHRQoL than players of other instrument groups. The study has a pilot character and aims to generate data to inform future research and targeted dental care concepts for this population.

Background: Germany has both one of the world's highest densities of professional orchestras and a rich amateur orchestra landscape, with approximately 30,300 musicians active across 863 amateur orchestras (BDLO). While making music, amateur musicians are exposed to physical and psychological demands that may affect oral health. Orofacial pain in musicians has been associated with sleep bruxism, perceived stress, and reduced sleep quality, all of which may negatively affect OHRQoL. Instrument-specific oral effects have been described particularly for wind instrumentalists compared with other instrument groups (e.g., string and percussion), related to specific playing technique and the coordinated action of the orofacial musculature. Playing a wind instrument has been linked to temporomandibular dysfunction, orofacial pain, and increased masticatory muscle activity. Unlike professional musicians, amateur musicians often have more heterogeneous and less systematic instrumental training, so a suboptimal playing technique and unfavorable posture may contribute to muscular overload. To date, no systematically collected data on orofacial pain, sleep-related problems, and OHRQoL of amateur musicians in Germany are available. Objective: To investigate orofacial pain, sleep-related problems, and OHRQoL among musicians in German amateur orchestras and to identify possible differences between instrument groups (woodwind, brass, string, percussion, and other instruments such as piano, harp, celesta). Hypothesis: Amateur musicians who play wind instruments (woodwind and brass) more frequently suffer from orofacial pain and experience a different OHRQoL than amateur musicians who play other instrument groups. Methods: This is a monocentric, cross-sectional online survey. A standardized online questionnaire is distributed to all 863 German amateur orchestras and additionally disseminated via the BDLO newsletter. The questionnaire covers demographic data (age, sex, instrument, duration of amateur orchestra membership) and specific questions on orofacial pain, sleep bruxism, perceived stress, and sleep quality. The German version of the OHIP-14 is used to assess OHRQoL. The survey is provided electronically via the University Medical Center Göttingen electronic survey system (EvaSys, ISO 27001 certified). Participation is voluntary and anonymous; completion of the questionnaire constitutes consent. Completion takes approximately 10 minutes, and the survey closes after 12 weeks for each participant. A reminder is sent to the orchestras and via the BDLO newsletter after 6 weeks. Statistical analysis: Continuous variables are presented as mean ± standard deviation or as median with interquartile range; categorical variables as absolute and relative frequencies. Group comparisons use the chi-square test, t-test, Mann-Whitney U test, or Kruskal-Wallis test as appropriate. Multivariable logistic regression is used to identify independent predictors of the presence of orofacial pain, and linear regression for the OHIP-14 summary score, each adjusted for relevant covariates. Odds ratios are reported with 95% confidence intervals and adjusted for age and sex. The study is conducted in accordance with the current version of the Declaration of Helsinki. The protocol is submitted to the Ethics Committee of the University Medical Center Göttingen prior to the start of the survey.
