Relationship between masticatory performance using a gummy jelly and food intake ability in Japanese complete denture wearers

Abstract

Twenty patients wearing complete dentures were asked to chew a gummy jelly, and their glucose extraction was measured. Two types of masticatory scores (MS1 and MS2) were calculated using a food intake questionnaire. The relationship between masticatory scores and glucose extraction was investigated. The values of masticatory scores were large when the amount of glucose extraction was also large, and there were significantly positive correlations between the two. There was also a positive correlation between MS1 and MS2. It was suggested that the food intake ability was high when the masticatory performance using a gummy jelly was high.

The impact of a newly constructed removable denture on the objective and subjective masticatory function

“…The association of an improved masticatory performance with food acceptability can be seen in removable denture patients, especially in edentulous. This shows the positive effect of an improved masticatory function and was in accordance with the study by Shiga et al [19], which found an association between improvements in the food acceptability and masticatory performance after denture treatment. It was also emphasized that a patient's texture acceptability is important for their perceived mastication, which helps them maintain and recover their masticatory performance [32].…”

“…One of the most widely recognized objective assessments is the masticatory performance (MP), which demonstrates a patient's ability to comminute a specific type of food during mastication. Several methods such as sieving [17], color-changeable chewing gum [18] and gummy jelly [19] have been used for such assessments. Notably, masticatory performance assessment by using gummy jelly [19][20][21][22][23] was widely used as a diagnostic tool due to its fast, easy and accurate application, which is beneficial in a clinical setting.…”

However, while objective assessments evaluate the actual masticatory function, it has been stressed that subjective evaluations are also appropriate and sensitive for measuring treatment outcomes.…”

“…al. [19] suggested that complete denture patients with a high masticatory performance tended to have a high food intake ability [19]. Thus, further clarification is needed with regards to the relationship between these two types of assessment.…”

Does Masticatory Ability Contribute to Nutritional Status in Older Individuals?

“…It remains unclear how masticatory ability affects the nutritional status. The relationship of subjective satisfaction with masticatory ability and objective masticatory ability (assessed via masticatory efficiency tests) in older individuals is inconclusive, with previous studies showing either a significant positive correlation [ 9 ] or the lack of a correlation [ 10 ]. In our own clinical observations, we have found that patients may be subjectively satisfied with their masticatory ability despite having a low masticatory efficiency; conversely, other patients may be dissatisfied despite having a high masticatory efficiency.…”
