“…Table 1 presents the means of the repeated measurements of Experiments 1 and 2. The mean values of Experiments 1 and 2 were found to be in agreement with those previously reported by researchers who applied the same or similar measurement methods [ 26 , 27 , 28 ]. Thus, the participants would be considered to be average.…”

In this study, we evaluated the reliability and reproducibility of widely implemented salivary flow rate and oral dryness tests. In experiment 1, twenty young and healthy Japanese participants volunteered to participate. For each participant, the oral moisture (OM) level, unstimulated whole saliva volume (U-WSV), and stimulated whole saliva volume (S-WSV) were measured at the same time on two separate days. In experiment 2, twenty-seven patients who were over 65 years of age volunteered to participate. The OM level and U-WSV were measured at the same time on two separate days. In Experiment 1, the intra-class correlation coefficients (ICCs) corresponding to the S-WSV, U-WSV, and OM level were 0.23, 0.28, and 0.16, respectively, for the young participants. In Experiment 2, the ICCs corresponding to the U-WSV/spitting and OM level were 0.83 and 0.12, respectively, for the older participants. The results of Bland–Altman analysis confirmed the absence of systematic error, with the exception of the OM level results in Experiment 2, which indicated systematic bias. In conclusion, we believe that there is currently no consistent and reliable screening test for assessing salivary flow rate and oral dryness, although the spitting test was determined to be highly reliable.

“…Nevertheless, oral hypofunction is a complex condition in which various aspects of oral functions are reduced; although it has clear diagnostic criteria and is considered a reversible dental disease in which early detection and appropriate measures can restore the normal limits of function, unlike dysphagia caused by progressive diseases [ 7 ]. Therefore, motivating patients to maintain and improve oral function through self-training and dental treatment, as well as providing comprehensive oral health instructions including lifestyle guidance, and nutritional counseling, are recommended as methods to manage oral hypofunction [ 25 ]. Previous reviews have reported that one-on-one dietary counseling in conjunction with dental treatment has the potential to change the patients’ eating habits [ 26 ].…”

This longitudinal study aimed to clarify the impact of regular oral health management for oral hypofunction on the oral function of older dental outpatients. The 68 participants enrolled in this study were older dental outpatients (mean age 78.5 ± 8.1 years). According to the number of declined oral examinations after the first exam, participants were assigned to the oral hypofunction group (Hypo group, ≥3), receiving regular oral health management with a leaflet at the dental clinic, or the pre-oral hypofunction group (Pre-hypo group, ≤2), which served as a control. At the second oral examination, after approximately 6 months to 1 year, the Hypo group showed significant improvement in the tongue-lip motor function (Oral diadochokinesis, ODK) /pa/, /ta/, and masticatory function, while the Pre-hypo group showed significant worsening in oral hygiene and oral wetness. Temporal changes in ODK /pa/, /ta/, and the number of declined examination items were significantly different between the groups. Multiple analysis revealed that the number of improved oral examination items were associated with presence of regular oral health management after adjusting for age, sex, number of visits, measuring period, and dental treatment. Regular comprehensive oral health management for oral hypofunction improves and maintains oral function among older dental outpatients.

“…Recent studies have shown that tooth loss, low occlusal force, and low masticatory and swallowing function might relate to low food intake or nutritional status 1‐4 . Moreover, some longitudinal studies on community‐dwelling older people report that poor oral function might be a predictor of physical frailty and sarcopenia 5‐7 . These findings highlight the extreme importance of improving and maintaining healthy oral function in older individuals.…”

Impact of oral health guidance on the tongue‐lip motor function of outpatients at a dental hospital

Objective To clarify the effect of oral health guidance on tongue‐lip motor function in the outpatients visiting the Showa University Dental Hospital (Tokyo, Japan). Background The management of the oral function of older people visiting a dental hospital is important. Previous studies have revealed that tongue‐lip motor function is easy to improve. However, the impact of oral health guidance on tongue‐lip motor function in the outpatients of dental hospital requires further elucidation. Materials and Methods The participants (n = 35) included patients who were diagnosed with low tongue‐lip motor function on evaluation by oral diadochokinesis (ODK) at the outpatient clinic. They underwent a second examination approximately 6‐12 months later. Their demographic characteristics were recorded. Oral health guidance was provided through an educational leaflet on oral hypofunction when the participants visited the clinic. It included content on tongue twisters, voice training and a range of movement and muscle training of the tongue and lip. Results Following oral health guidance on tongue‐lip motor function, the ODK values changed from 5.6 at the first examination to 6.0 at the second for /pa/, from 5.6 to 5.8 for /ta/ and from 5.2 to 5.4 for /ka/. This improvement was not significantly associated with age, sex, measurement period or number of visits. Conclusion The findings of this longitudinal study suggested that oral health guidance using an oral hypofunction educational leaflet may be effective in improving the tongue‐lip motor function of outpatients who had low tongue‐lip motor function, regardless of the measurement period or the number of visits to the dental hospital.
