Nasalance of Brazilian Portuguese-speaking populations from two different states.
OBJECTIVE
To measure the nasalance scores of Brazilian Portuguese-speaking young adults from the states of Sao Paulo and Minas Gerais in order to investigate whether dialect variations and gender affect these scores.


METHODS
Nasalance was assessed in 36 individuals: 20 native residents of Sao Paulo state (mean age=23 y.o.) and 16 native residents of Minas Gerais state (mean age=24 y.o.), following the same criteria. Nasalance measures were taken using the Nasometer II 6400 (KayPentax) device based on the reading of three texts (nasal-1, nasal-2, and oral). Intergroup nasalance scores were compared using the unpaired Student's t test considering two experimental groups.


RESULTS
The nasalance scores in individuals from the states of Sao Paulo and Minas Gerais were 52.7% and 48.8% for the nasal-1 text, 49.6% and 49.9% for the nasal-2 text, and 14.3% and 9.8% for the oral text, respectively. Statistical analysis comparing the mean nasalance scores in both groups showed significant difference (p=0.03) only for the oral text, in which individuals from Sao Paulo state presented higher scores.


CONCLUSIONS
Although nasalance scores were lower in individuals from Minas Gerais state compared with those of individuals from Sao Paulo state, both groups presented values within the normal range. The variable gender was not relevant in the nasalance assessment; however, a tendency for higher scores was observed in women compared with men from Minas Gerais state in the same group in the reading of the nasal-2 text. This study contributes to the knowledge of nasalance reference scores for two different populations of Brazilian Portuguese speakers; however, the results herein reported should be interpreted with caution due to the small study sample size.
