영문 초록

For the comparisons of dental archs and crowdings between musical wind instrument players groups and non-wind instrument players groups, 64 male wind instrument players and 31 non-wind instrument players group were selected. The results of the measurements were as follow. 1. Upper intercanine widths, upper basal arch widths, lower basal arch widths were statistically significant between musical wind instrument players groups (Class A, Class B) and non-wind musical instrument players group. 2. The mean value of upper intercanine width m Class A (37.3 ± 2.3mm) was greater than in Class B (36.2 ± 1.7mm) and non-wind musical instrument players group(36.0 ± 1.6mm) 3. The mean value of lower basal arch width m Class B (42.2 ± 2.5mm) was greater than that in non-wind instrument players group (39.5 ± 2.8mm). 4. The differences m the mean values of crowdings between Class A and Class Band non-wind instrument players group were not statistically significant.
