“…The responsiveness of the iMP scale may be improved by decreasing the number of chewing strokes for the gum or increasing the hardness of the chewing gum. In the subgroup analysis, lower iMP score in pre‐treatment was associated with greater responsiveness, which agrees with the three MP tests 24 and subjective assessments of masticatory function 30 . A regression to the mean effect is responsible for this association.…”

Background:The existing masticatory performance (MP) tests cannot comprehensively evaluate objective masticatory function. Objectives:We aimed to examine the construct validity and responsiveness and determine the clinically minimum important difference (MID) and related factors of a newly developed MP scale to integrate food biting, comminution and mixing ability in patients with removable partial dentures (RPDs).Methods: Masticatory performance tests using gummy jelly, peanuts and colourchangeable gum were performed before and 3 months after RPD treatment in 248 partially dentate patients. A 10-point ordinal subscale was created for each MP test based on the distributions of MP values, and the three subscales were integrated into a single scale (iMP scale). We analysed the correlations between MP values and iMP scores and determined the effect size for RPD treatments and the MID on the basis of patient perception of chewing ability.Results: iMP scores exhibited moderate correlations with the three MP values (|ρ| = 0.73-0.79, p < .001) and with the change scores (|ρ| =0.61-0.64, p < .001). The mean iMP score significantly increased after RPD treatment (p < .001), and the effect size was 0.35. Of the 248 patients, 55 (22%) reported a slight improvement in chewing ability with a mean iMP score change of 2.1 points. Sex and the number of missing teeth were significantly associated with iMP scores (p < .05). Conclusions:The iMP scale comprehensively evaluated objective masticatory function, including food biting, comminution and mixing ability in RPD wearers, and an increase of two points on the iMP scale was considered to be the MID in RPD treatments.

“…The relationship between masticatory function and dental prosthesis use has been studied before; however, these studies included only a small number of participants or participants with residual natural teeth [9][10][11]. Since natural teeth perform various physiological functions, such as proprioception via the periodontal ligament [23], the presence/absence of natural teeth can significantly affect masticatory comfort [24].…”

Prosthodontic rehabilitation of completely edentulous patients is challenging. Previously, the treatment options were limited to removable complete dentures, but since the introduction of dental implants, several implant-based restorative modalities have emerged [1]. At the inception of screw-type dental implants, an implantsupported fixed complete denture was used for cross-arch stabilization by placing five to six implants between the bilateral mental foramina [2]. The treatment has since evolved to the placement of mul-tiple implant-supported fixed partial dentures without cross-arch stabilization [3,4]. Further, a combination of removable dentures and implants is also available. McGill and York consensus statements recommend a two-implant-supported mandibular overdenture as the first choice of treatment for edentulous mandibular arches [5,6]. The stability of mandibular removable complete dentures is usually less than that of maxillary removable dentures; therefore, implant therapy is often recommended for the edentulous mandible [5][6][7]. The use of various restorative modalities allows completely edentulous patients to have different combinations of maxillary and mandibular prostheses.Further, the choice of the prosthetic restorative modality can affect treatment outcomes in a completely edentulous patient. Prosthetic restorations affect the chewing ability and nutrient intake [8][9][10][11], which can further affect the patients' overall health and qual-J Prosthodont Res. 2022; **(**):

Background Although the food intake score (FIS) from conventional food intake questionnaires is widely used, the evaluation method, number of foods and food selection used in the questionnaire can be improved. Objective This study aimed to evaluate the usefulness of a newly devised FIS in removable denture wearers. Methods A total of 219 removable denture wearers were asked about their food intake, and three types of FIS (FIS1, FIS2 and FIS3) were calculated as subjective parameters. FIS1 and FIS2 are conventional FISs, while FIS3 is the FIS devised in this study. The amount of glucose extracted (AGE) when participants chewed gummy jelly was used as an objective parameter. The relationship between the three FISs and that between each FIS and AGE were investigated. Stepwise multiple linear regression analysis was performed with AGE as the dependent variable and age, sex and FIS as independent variables. Results The three types of FISs were positively correlated. A positive correlation was also found between FIS and AGE. The correlation coefficient was the largest in FIS2 and decreased in the order of FIS3 > FIS1; however, the values of FIS2 > FIS3 were similar. Multiple linear regression analysis revealed that sex and FIS were significantly associated with AGE. Conclusion For denture wearers, the newly devised FIS3 was useful and evaluated masticatory performance, as well as or better than FIS1 and FIS2.
