Compatibility of two types of gummy jelly tests for detecting decreased masticatory function

Abstract

Objective This study aimed to verify the compatibility of masticatory performance tests using different two types of gummy jellies. Background data discussing the present status of the field Compatibility between the glucose concentration measuring method (GC) and 10‐steps visual scoring method (VS), which are masticatory performance tests for diagnosing decreased masticatory function (DMF) in oral hypofunction and the use of different types of gummy jelly, has yet to be confirmed. Materials and methods The participants consisted of 134 Japanese older people (51 men and 83 women). GC, VS and the increased surface area measuring method (ISA), as an alternative analysis method for VS, were conducted to evaluate masticatory performance. Cohen's Kappa coefficient was used to verify the consistency for detecting DMF between GC and VS. Pearson's correlation coefficient was used to analyse the relationship between GC and ISA. Each masticatory performance was compared among three different groups for the number of residual teeth. Cut‐off values of VS and ISA for DMF that were consistent with GC were identified. Results Glucose concentration measuring method and VS showed an excellent consistency (Kappa coefficient = 0.86). There was a high positive correlation between GC and ISA (r = .70). However, the change in masticatory performance according to the number of teeth was different between GC and VS/ISA. The cut‐off values of VS and ISA were a Score of 2 and 1687 mm2, respectively. Conclusion Glucose concentration measuring method and VS/ISA remained fairly consistent for detecting DMF, which might be useful information to interconnect the various studies on masticatory performance.

Masticatory Performance Test Using a Gummy Jelly for Older People with Low Masticatory Ability

“…In addition, the evaluation methods of both tests were based on the same measurement principle of the degree to which the test sample was crushed. The previous study which evaluated the compatibility of two tests of masticatory ability using gummy jellies of different sizes and hardness reported that the test results showed a positive correlation, which supports the findings of the present study [ 19 ].…”

Features of Masticatory Behaviors in Older Adults with Oral Hypofunction: A Cross-Sectional Study

“…Since masticatory performance was thought to be closely related to masticatory behaviors, in the present study, masticatory performance was evaluated not only by the score method, but also by an imaging method to evaluate the increase in surface area of comminuted gummy jelly in order to give a detailed evaluation. With the evaluation of masticatory performance using a test gummy jelly, the significant relationship between the score method and imaging was previously demonstrated [ 17 , 41 ]. In the present study, no significant correlation was found between increased surface area of the comminuted gummy jelly and number of chews of a rice ball.…”

Reliability between the two‐colour chewing gum and the gummy‐jelly tests used for the assessment of masticatory performance

“…FruitSwing Hue-Check mastication can adversely impact both. 6,22 The repercussions of this decline can extend beyond oral health and crucially affect the overall well-being, especially in age-advanced frail older adults. 7,23 Therefore, assessing and monitoring masticatory performance in older adults is quite pertinent.…”

“…2 Recently, a shift towards simpler evaluation techniques for the assessing masticatory performance has occurred, and these techniques employ novel test materials including chewing gum, 3,4 paraffin wax, 5 or gummy jelly. 1,2,6,7 The chewing gum methods have been more frequently used in recent times and have gained popularity because of their ease of use, making them less cumbersome and less time-consuming. This method involves chewing either colour-changing chewing gums or two-colour chewing gum for a specified number of chewing cycles (depending on the method).…”
