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.
Highlights
The production of sufficient saliva to moisten food and bind it into a bolus is indispensable for good chewing and deglutition,[1] which are influenced by food characteristics
Healthy patients submitted to xerostomia induction by the administration of systemic anticholinergic medications display compromised masticatory efficiencies, due to a lack of saliva after chewing natural foods or artificial material.[4,5]
Saliva plays an important role in speech; one report found that 48% of patients who complain about xerostomia report difficulties with communication.[3]
Summary
The production of sufficient saliva to moisten food and bind it into a bolus is indispensable for good chewing and deglutition,[1] which are influenced by food characteristics. For example, require more chewing cycles and longer times in the mouth until swallowing than other foods for sufficient breakdown and enough saliva to form a coherent bolus.[2] Difficulties in chewing dry foods and swallowing have been reported by 25% and 29% of xerostomic patients, respectively.[3] healthy patients submitted to xerostomia induction by the administration of systemic anticholinergic medications display compromised masticatory efficiencies, due to a lack of saliva after chewing natural foods or artificial material.[4,5]. The mandibular tridimensional track during communication has been documented,[6,8] no objective analysis of jaw movements during speech has been made relative to salivary flow
