“…Reports suggest that salivary gland massage increases blood flow and parasympathetic activity in the surrounding areas of salivary glands (Zelles et al 1999;Weerapong et al 2005). In addition, another report shows a positive correlation between bite force and salivary flow, regardless of age and gender (Yeh et al 2000). In the present study, a significant positive increase in unstimulated and stimulated salivary flow rates was observed after completion of the exercise program for oral function in subjects of the intervention group with 20 or more remaining teeth, whereas no improvement was observed in other groups.…”

In Japan, one of the duties of the long-term care insurance system is the prevention of oral function degradation. Although various exercise programs for oral function have been developed and practiced in Japan, to date, no study has reported their effects. In the present study, we examined the effects of an exercise program on oral functions in healthy elderly people. Healthy elderly people participated in the study and were randomly divided into intervention and control groups (39 subjects/group). The exercise program consisted of four exercises: exercise for expression muscles, tongue, salivary glands, and swallowing. Before and after a six-month intervention period, we evaluated changes in oral functions, namely bite force, swallowing ability, and salivary flow rate. Fifty-four subjects completed the study protocol: 26 and 28 subjects from intervention and control groups, respectively. A significant improvement in all oral functions, including bite force, swallowing ability, as well as unstimulated and stimulated salivary flow rate, was observed in the intervention group after six months, whereas no improvement was observed in the control group. Further, among the intervention group, a significant improvement in oral functions was observed in 17 subjects with 20 or more remaining teeth, whereas no improvement was observed in the other nine with less than 20 teeth. Our results suggest that oral functions significantly improve after conducting a six-month exercise program for oral function. Further, this improvement appears to be influenced by the number of remaining teeth.exercise program for oral function; healthy elderly people; long term care insurance; stretching exercise; number of remaining teeth.Tohoku

“…The differences in bite forces were most likely not due to age alone [3,38], but probably also reflected submaximal contractions in the older women who in many cases expressed fear of breaking large fillings or damaging bridge constructions when biting hard on the transducer between the molar teeth. This fear was not present in the young women or when they were biting in the intercuspal position during the recording of the EMG max .…”

Background: Age-related effects on physiological stress reactions regarding changes in salivary cortisol concentration, saliva flow rate, and masticatory muscle activity, as well as the corresponding perceived mental stress and performance in response to acute stressors, have not yet been fully described. Objective: Thus, the aim of this study was to assess the age-related variations in these variables in response to minor acute and naturalistic stressors in terms of computer tasks. Methods: 13 aged (60–70 years old) and 13 young (20–30 years old) women with frequent practice and long experience with computer use were recruited by personal contact and flyers. The subjects were healthy and had full dental arches and no orofacial pain. The computer tasks were randomized and comprised a mentally demanding, modified Stroop colour-word test (CWT) and a less demanding reference test, both with a duration of 20 min and with equal physical demand. Visual analogue scales for global assessment of mental stress and perceived task difficulty and performance, measurements of saliva flow rate and cortisol concentration (unstimulated whole saliva), as well as surface electromyography of the temporalis and masseter muscles were used for assessment, and Spearman correlation analysis and Anova with repeated measures were used for statistical evaluation. Results: The perceived task-related stress and task difficulty were significantly higher and the personal satisfaction with the task performance significantly poorer in the aged women. The cortisol concentration, indicating the stress level, showed a small, but significant increase in response to the tasks. Also the saliva flow rate increased. This response was most pronounced in the aged and during the CWT. The average electromyogram varied significantly between age groups and tasks, with higher levels and shorter relative periods with gaps in the aged women and in the CWT. In addition, the peak activity of the jaw elevator muscles at mouse clicking was significantly elevated as a form of co-activation or attention-related activity. Conclusions: The study showed marked differences in the response to mental demands in aged as compared with young women. The mental stress, reflected by increases of salivary cortisol concentration, saliva flow rate, visual analogue scale ratings, and activity level of the jaw elevator muscles, was more pronounced in the aged women in response to the computer tasks.

ÖZETAkut bakteriyel parotitis (ABP) çok erken ve ileri yaşta görülen bir enfeksiyondur. Yeterli mayi desteği, ağız hijyeni, oral beslenme ve çoklu ilaç kullanımından kaçınılarak enfeksiyon önlenebilmektedir. Tanı için parotis ultrasonografisi kullanılabilmektedir. Akut bakteriyel parotitis erken tanı ve uygun antibiyotikle sorunsuz ve kısa sürede tedavi edilebilir. Geç tanı konulan ve antibiyotik tedavisine dirençli olgularda mortalite görülebilmektedir. Bu yazıda 65 yaşın üstünde yoğun bakımda izlenen ABP tanılı dört olgu sunulmuştur. İlk olguda çoklu ilaç kullanımı, sıvı kısıtlaması ve oral beslenememe, ikinci olguda oral beslenememe, üçüncü olguda kötü ağız hijyeni, demans ve yeterli sıvı alamama ve dördüncü olguda ise oral beslenememe nedeniyle ABP geliştiği düşünülmektedir. Belirtilen risk faktörü olan olgular dikkatli bir şekilde takip edilirse, yoğun bakım yatış süresi uzamamış ve mortalite oranları da artmamış olacaktır. Anahtar Sözcükler: Akut bakteriyel parotitis, ultrasonografi, tedavi, yoğun bakım. ACUTE BACTERIAL PAROTITIS IN INTENSIVE CARE PATIENTS: FOUR CASE REPORTS ABSTRACTAcute Bacterial Parotitis (ABP) is an infection seen in very early and old ages. The infection can be prevented by sufficient fluid support, mouth hygiene, oral feeding and avoiding multiple medication use. Parotis ultrasonography can be used for diagnosis. Acute Bacterial Parotitis can be treated in a short time and free of problems with early diagnosis and appropriate antibiotics. Mortality can be seen in cases which are late diagnosed and which are resistant to antibiotic treatment. This article presents four case reports over the age of 65 with a diagnosis of ABP, who are monitored in the intensive care. It is thought that the first case developed ABP because of multiple medication use, liquid restriction and oral feeding difficulty, the second case because of oral feeding difficulty, the third case because of bad mouth hygiene, dementia and not getting enough liquid and the fourth case because of oral feeding difficulty. If the cases with the stated risk factors are carefully followed, intensive care hospitalization period will not be prolonged and mortality rates will not increase.
