Resumo

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.
