“…In this study, all MPT values for the CG, both for vowels and fricatives, achieved the minimum time expected for adult women,14.04 s 4,29,30 , while for the elderly who wore upper dental prosthesis, MPT values were below the minimum value expected (EG) 18,32 (Table 1). These findings corroborate the fact that aging results in decreased MPT 4,7,9,11 and that the use of upper dental prosthesis can interfere negatively in maintenance of vocal emission 33 .…”
