The purpose of this sectional study is first, to assess the orofacial lesions that could be associated with playing music instruments and second, to compare the existing oral hygiene and dental conditions between musicians and dental students. Material and methods. Two cohorts, the first one consisted of students from the High Conservatory of Music “Joaquín Rodrigo” of Valencia (n = 38), while the second cohort, harmonized with the first and serving as the control group, comprised of oral hygiene-motivated (n = 38), fourth-year dental students from the University of Valencia School of Dentistry. The total population in the study included 28 women and 48 men, with a mean average age of 22.89 ± 1.79 years. The two groups were evaluated by using the Plaque Index, community periodontal index of treatment needs (CPITN), Angle classification, overjet, overbite, crowding, dental abrasion, lip abrasion or erosion, herpes labialis, open deviation, presence of joint sounds, and pain to muscle palpation. Kolmogorov-Smirnov and de Shapiro-Wilk tests were used to assess the normality of the data and a non-parametric analysis (Kruskal-Wallis) was utilized in order to compare the data obtained from both groups. Moreover, a Student t test was used to analyze any sexual dimorphism. Results. Oral hygiene was lower in musicians than dentists, so the CPTIN was significantly greater in five of the six sextants of the musician population. A significant difference was found between the study groups, with crowding, lip erosion, and orbicularis and buccinator muscle pain being greater in musicians. Conclusions. Musicians have lower oral hygiene, greater crowding, lower lip erosion, and increased muscle pain when the orbicularis and buccinators muscles are compared.
