“…The resting fl ow rate is considered to be low at ^ 0.1 ml/min and the stimulated fl ow rate at ^ 0.7 ml/min [Ericsson and Hardwick, 1978]. The fl ow rates of subjects in this study were far lower than the standard; some of them at some sampling times during the study even had no measurable volume of saliva.…”

The aim of the study was to examine the persistence of oral Streptococcus mutans in nasopharyngeal carcinoma patients after radiotherapy. Ten subjects, ranging in age from 20 to 67 years, participated. DMFT/DMFS, salivary level of mutans streptococci and oral health status were recorded. Pooled plaque samples were obtained from the cervical margins and the interproximal regions of all the teeth and the occlusal surfaces of the molars prior to, immediately after, 3 and 6 months after the completion of radiotherapy. At least 10 colonies of S. mutans were isolated from each subject and totally 645 isolates were genotyped by restriction endonuclease analysis. The results showed that the salivary level of S. mutans increased significantly with the reduction of salivary flow rate after radiotherapy. Each subject had at least 1 genotype of S. mutans isolated throughout the follow-up period. In 3 subjects who initially carried 2 or more genotypes, 1 or 2 genotypes of S. mutans could not be detected 3 months after treatment. Moreover, the genotypes that became undetectable were predominant bacteria in the first sampling. The result indicated that most S. mutans genotypes were persistent after radiotherapy but some genotypes that might not adapt to the alteration of oral environment became undetectable.

“…Specifically, the clinical hallmark of hyposalivation for stimulated saliva has been described as an SFR less than 0.70 mL/min (9,25,26). However, salivary hypofunction is difficult to assess, and the establishment of standard values has been impaired, mainly because IQR, interquartile range; delta MSVP, difference for maximum systolic velocity at external carotid artery; delta PIP, difference for pulsatility index at external carotid artery; delta RIP, difference for resistive index at external carotid artery; delta FVP, difference for flow volume at external carotid artery; delta MSVS, difference for maximum systolic velocity at facial artery; delta PIS, difference for pulsatility index at facial artery; delta RIS, difference for resistive index at facial artery; delta FVS, difference flow volume at facial artery.…”

“…Assuming this trend continues for up to 1 minute, the amount of saliva secretion during chewing for 1 minute reaches about 1.2 ml, which is less than the 1.4-1.8 ml/min secreted during chewing of paraffin wax. 20,21 This is probably because paraffin wax with no moisture content requires more saliva during chewing than gummy jelly with moisture content of about 40%. However, the reason for a relatively greater amount of saliva secretion during chewing for 10 seconds than with other chewing times is thought to be because, in addition to stimulation of oral sensation due to chewing, gummy jelly provides greater gustatory stimulus than other chewing times.…”

This study confirms that the saliva secreted during gummy jelly chewing has an influence on the masticatory performance which was obtained by measuring glucose extraction. AbstractPurpose: The purpose of this experiment was to clarify whether the amount of saliva secreted during the chewing gummy jelly affected the assessment of masticatory performance. Methods:Twenty healthy subjects were asked to chew 2 g of gummy jelly for 10, 15, and 20 seconds and the amounts of glucose extraction and saliva secretion were measured. The changes in both glucose extraction and saliva from 10 to 20 seconds were investigated. Next, the amount of glucose extraction excluding the effect of saliva (extraction B) was divided by the amount of glucose extraction measured (extraction A), and the results for the two chewing times were compared. Results:The amount of glucose extraction increased proportionally as the chewing time progressed and the change was significant. Although the amount of saliva secretion increased as the chewing time progressed, the change differed from the proportional change in glucose extraction. The amount of saliva secretion was extensive for the first 10 seconds and increased about 0.1 ml every 5 seconds. The ratio of the extraction B to extraction A was between 1.03 and 1.05, and there was a significant difference between each pair of chewing times. Conclusion:From these results it was concluded that the amount of saliva secretion increased during chewing of gummy jelly and affected the assessment of masticatory performance, and this effect was less than 5 % for chewing of up to 20 seconds.
