“…The supernatant fluid of the solution was sampled, and the concentration of dissolved glucose from the comminuted jelly was measured with a portable blood glucose metre (Glutest, Sanwa chemical Laboratory Co., Nagoya, Japan). 23 A linear regression analysis showed that the concentration of glucose had a significantly high correlation to the surface area (mm 2 ) of the comminuted jelly (r = 0.993, p < 0.01). The masticatory performance was assessed by calculating the surface area of particles (mm 2 ) from the glucose concentration, using linear regression.…”

“…Mixing ability is measured by a colorimeter. Shearing ability is evaluated using a test gummy jelly (Test Gummy Jelly for Evaluating Masticatory Performance; UHA Mikakuto Co., Ltd., Osaka, Japan) [31]. The participants are instructed to chew the test gummy jelly using 30 chewing cycles, depending on their preference.…”

BackgroundIndividuals who are edentulous have a lower intake of fruit, vegetables, fiber, and protein compared with their dentate counterparts because tooth loss is accompanied by a decrease in ability to chew. Whether or not a combination of prosthetic rehabilitation and simple dietary advice produces improvement in dietary intake among edentulous persons is unclear. We aim to investigate the effect of a simultaneous combination of simple dietary advice delivered by dentists and provision of new complete dentures on dietary intake in edentulous individuals who request new dentures.Methods/designThrough a double-blinded, parallel, randomized controlled trial in which 70 edentate persons who request new complete dentures will be enrolled, eligible study participants will be randomly allocated to either a dietary intervention group receiving dietary advice or to a control group receiving only advice on the care and maintenance of dentures. Outcome measures include daily intake of nutrients and food items, assessed using a brief self-administered diet history questionnaire; antioxidant capacity, determined using blood and urine samples; nutritional status, assessed with the Mini-Nutritional Assessment-Short Form; oral health-related quality of life, assessed with the Japanese version of the Oral Health Impact Profile-EDENT and the Geriatric Oral Health Assessment Index; subjective chewing ability; masticatory performance, assessed using a color-changeable chewing gum and a gummy jelly; patient self-assessment of dentures; mild cognitive impairment, assessed with the Japanese version of the Montreal Cognitive Assessment; and functional capacity, assessed with the Japan Science and Technology Agency Index of Competence. Outcome measures, except for antioxidant capacity, are to be implemented at three time points: at baseline and at 3 and 6 months following intervention. Antioxidant capacity data are to be collected twice: at baseline and at 3 months following intervention. Differences between the groups at 3 and 6 months and within-group changes are to be compared using the paired t test.DiscussionSimple dietary advice that can be implemented by a dentist would be more practical in clinical practice than tailored dietary counseling. The results of this study will provide beneficial information on dietary intake changes for both edentulous individuals requesting new complete dentures and dentists.Trial registrationUniversity Hospital Medical Information Network Center Unique Trial Number: UMIN000017879.

“…These can be broadly divided into methods based on the patient's own subjective evaluations, and objective methods that use some sort of objective index for evaluation. Other methods measure changes in ingredients eluted from within test materials, such as dye eluted from capsules containing pigment-coated granules (Nakashima et al 1989) and the optical density method, which utilizes glucose eluted from gummy jelly as an indicator (Okiyama et al 2003, Ikebe et al 2005. Objective evaluation methods include the following techniques.…”

“…Objective evaluation methods include the following techniques. Of all these evaluation methods, the glucose elution method using test gummy jelly is a simple, clinically applicable method of measuring masticatory performance, and has been shown to provide high accuracy and reproducibility provided that the method of measurement is strictly controlled (Ikebe et al 2005). Other methods measure changes in ingredients eluted from within test materials, such as dye eluted from capsules containing pigment-coated granules (Nakashima et al 1989) and the optical density method, which utilizes glucose eluted from gummy jelly as an indicator (Okiyama et al 2003, Ikebe et al 2005.…”
