“…The smaller the particles size, the better the masticatory performance. The colorimetric technique is based on the mixing degree of a 2-color material (usually color-changeable gum or paraffin wax), determined by visual matching with color scales [ 23 ] or digital analysis with a software program [ 24 , 25 ]. Both procedures seemed equal regarding test reliability [ 21 ].…”

Background: Mini dental implant (MDI) overdenture rehabilitation for the edentulous maxilla is a valuable, less invasive and affordable treatment alternative for complete removable dentures (CRD). However, comparative quantification of masticatory performance in different oral conditions are scarce. Purpose: This study compares objective masticatory performance of dentate groups, maxillary CRD and MDI overdentures and subjective masticatory performance in maxillary CRD and MDI overdentures. Materials and Methods: Four groups were defined, age 20+ dentate dental students (DS), age 50+ complete dentate subjects (DP), age 50+ maxillary CRD or MDI overdentures/dentate mandible. Objective masticatory performance was evaluated by measuring circular Variance of Hue (VOH) or the mixture degree of two-color chewing gum (Hue-check View Gum® Test). Additionally, subjective masticatory comparison was investigated in the CRD and MDI groups, with a visual analogue scale (VAS) for different food consistencies and the Oral Health Related Quality of Life (OHRQL) OHIP-14 questionnaire. Results: The mean VOH was 0.11 (SD 0.50, range 0.05–0.27) for the dentate dental 20+ students, 0.13 (SD 0.08, range 0.03–0.31) for the 50+ dentate group (p = 0.774), 0.41 (SD 0.41, range 0.14–0.76) for the CRD group and 0.39 (SD 0.18, range 0.07–0.76) for the MDI group (p = 0.725). Based on the VAS scores, no improvement was found between the CRD and the MDI overdenture group (p > 0.050). The mean OHIP-14 total score was 12.10 (SD 15.87, range 0–56) for CRD, while the MDI group (p = 0.039) saw a significant improvement to 2.85 (SD 2.85, range 0–15). Conclusion: Comparable results in objective masticatory performance were registered in dentate 20+ and 50+ subjects with a remarkable inferior outcome for the CRD and MDI group. Compared to CRD, MDI overdentures revealed no substantial improvement in subjective and objective masticatory performance. However, for MDI a significant increase in OHRQL was apparent.

“…First, we did not assess participants’ salivary flow rate or determine whether they had Sjogren's syndrome. However, in a previous study, 29 salivary flow was not a significant predictor of masticatory performance assessed with two‐coloured chewing gum. Similarly, in another previous investigation, 27 individuals with higher salivary flow rates did not have higher swallowing thresholds in a test performed with peanuts.…”

Objective: To evaluate the association of masticatory function with prosthetic rehabilitation status and dental prosthesis functionality in nursing home residents.Background: Prosthetic rehabilitation status and dental prosthesis functionality may adversely affect mastication of older people, and this relationship is underestimated in nursing home residents. Materials and methods: This cross-sectional study included 179 nursing home residents who used dental prostheses [mean (SD) age: 78.9 (9.0) years]. Masticatory function data were determined by assessing (a) masticatory performance using twocolour chewing gum, and (b) swallowing thresholds by counting the number of peanut chewing cycles. Older adults were categorised as: (1) using dental prostheses in both jaws (n = 100) and (2) partially dentate using removable partial dental prostheses (RPDPs) or complete dentures (CDs) in only one jaw (n = 41), or (3) edentulous using CD in only one jaw (n = 38). Stability, retention, occlusion, vertical dimension and defects were considered in assessing dental prosthesis functionality. Results: Greater variance of hue (VOH) of the chewing gum and lower swallowing thresholds (worse masticatory function) was associated with edentulous using CD in only one jaw. Older adults wearing dental prostheses with poor occlusion and vertical dimensions presented worse masticatory function. Dental prosthesis stability was associated with lower VOH values. Higher number of chewing cycles while eating peanuts was associated with non-broken dental prosthesis use. Conclusion: Edentulous participants using CD in only one jaw and non-functional dental prosthesis use negatively affect the masticatory function of nursing home residents.

“…However, from the present results, we could not find a significant difference in protein intake between those with ≥20 and 10–19 remaining teeth in the absence of a dental prosthesis. In addition, a previous study revealed that the number of occlusal units was strongly associated with chewing efficiency 27 . Therefore, it is considered that, for those with 10–19 remaining teeth, a certain number of premolar and molar teeth remained, occlusal units were preserved and chewing efficiency did not greatly differ from that of individuals with ≥20 remaining teeth.…”

BackgroundTooth loss is associated with reduced protein intake, which leads to sarcopenia and frailty in older adults.ObjectiveTo evaluate the protective effect of dental prostheses on decreased protein intake in older adults with tooth loss.MethodsThis cross‐sectional study was based on a self‐reported questionnaire targeting older adults. Data were obtained from the Iwanuma Survey of the Japan Gerontological Evaluation Study. We used % energy intake (%E) of total protein as the outcome and the use of dental prostheses and number of remaining teeth as explanatory variables. We estimated the controlled direct effects of tooth loss by fixing the use/non‐use of dental prostheses based on a causal mediation analysis, including possible confounders.ResultsAmong 2095 participants, the mean age was 81.1 years (1SD = 5.1), and 43.9% were men. The average protein intake was 17.4%E (1SD = 3.4) of the total energy intake. Among participants with ≥20, 10–19 and 0–9 remaining teeth, the average protein intake was 17.7%E, 17.2%E/17.4%E and 17.0%E/15.4%E (with/without a dental prosthesis), respectively. Compared to participants with ≥20 remaining teeth, those with 10–19 remaining teeth without a dental prosthesis did not have a significantly different total protein intake (p > .05). Among those with 0–9 remaining teeth without a dental prosthesis, total protein intake was significantly low (−2.31%, p < .001); however, the use of dental prostheses mitigated the association by 79.4% (p < .001).ConclusionOur results suggest that prosthodontic treatment could contribute to maintaining protein intake in older adults with severe tooth loss.
