Abstract: The aim of this study was to evaluate whether patients with hyposalivation present damaged mastication or mandibular movements during speech. Forty subjects composed 2 groups: control and hyposalivation. Masticatory performance was assessed with a silicon-based artificial material and a 10-sieve method. Mandibular movements during speech were observed with a 3D jaw-tracking device. Data were analyzed with Student's t-test or the Mann-Whitney method (P < 0.05). The masticatory performance (mm) of control and hyposalivation were 4.40 +/- 0.62 and 4.74 +/- 1.34, respectively. Outcomes for speech movements (mm) were as follows: maximum vertical opening amplitude (10.8 +/- 4.2; 9.9 +/- 2.7) and displacements to the right (1.0 +/- 0.8; 0.5 +/- 0.6), left (1.8 +/- 1.4; 2.3 +/- 1.2), or anterior-posterior (2.8 +/- 1.1; 2.9 +/- 1.0) for control and hyposalivation, respectively. No statistical difference was found between groups for any variable. The results indicated that hyposalivation did not affect masticatory performance or mandibular movements during speech. Identifier: NCT01020084.
