Dentofacial morphology in children playing musical wind instruments: a longitudinal study

Area of Science:

• Dentofacial Morphology
• Physiology of Wind Instrument Playing

Background:

• Wind instrument playing necessitates increased respiratory function and orofacial muscle engagement.
• The long-term effects of these demands on craniofacial development are not fully understood.

Purpose of the Study:

• To investigate the longitudinal impact of wind instrument practice on dentofacial morphology.
• To compare craniofacial development in young wind instrument players with non-musician control groups.

Main Methods:

• Longitudinal study analyzing lateral cephalograms and dental casts from ages 6 to 15.
• Comparison of wind instrument players with age-matched control subjects.
• Correlation of dentofacial changes with daily practice hours.

Main Results:

• Wind instrument players exhibited a statistically significant decrease in anterior facial height compared to controls.
• Musicians demonstrated significantly wider dental arches.
• These changes correlated with the intensity and duration of instrument practice.

Conclusions:

• Sustained wind instrument playing during growth significantly influences dentofacial morphology.
• Increased orofacial muscle activity and intra-oral pressure are key factors driving these observed changes.
• Findings suggest a need for considering these effects in orthodontic and pediatric dental assessments.
