Abstract
drooling and feeding disabilities. In order to examine the cause of the abnormality of the chewing function, a developmental test, chewing test, salivary flow rate, lip pressure, electromyography(chewing cycle, muscle activity), Dental Prescale®test(occlusaclo ntact area, biting strength, occlusal pressure) were used.
The results of these examinations showed that the resting and stimulated saliva was in the normal range and the rip closing pressure was greater than the normal range. However, the occlusal contact area and biting strength, occlusal pressure and masticatory efficiency were smaller than the normal range. These findings revealed that the chewing ability of the patient was inferior to the normal range and it took a long time to create the state of swallowing for the properties of food bolus. Sinusitis causes lip closing failure and drooling.
These results of the physiological examination seemed to be effective for the diagnosis of the feeding disabilities.
