Background/purpose: A relationship between malocclusion and intraoral pressure is suspected but ill understood. This study explores intra-oral pressure changes during normal swallowing to assess differences in patterns of command saliva and water swallows. Materials and methods: We used a custom-made appliance fitted with miniature pressure transducers located along the midline at the anterior-, mid-, and hind palate to measure absolute pressures during command water and saliva swallows. Data were obtained from eight healthy volunteers (six males, two females; 24–35 years) with full permanent dentitions. Following accommodation, volunteers performed 10 mL water and saliva swallows on command. Each volunteer performed the swallows three times on 5 separate days, yielding data from 15 swallows for each individual. Results: Each participant had a distinct pressure response during swallowing. At all three locations, negative pressure amplitude was greater than positive pressure amplitude, with no significant difference between swallowing saliva and water. There was a larger rate of negative pressure development (P |
