“…The majority of the research investigating the masticatory values of chewing 3g peanuts used 20 chewing strokes. Of these, Manly and Braley, 1 Okiyama et al, 12 and Yamashita et al, 15 who had analyzed healthy subjects with full dentition, reported 78%, 76.8%, and 75.8%, respectively, as the masticatory value. In this experiment it was 79.3%, which was very close to the ones reported by the above mentioned authors.…”

“…Manly's sieve method, 1 where a certain quantity of test food is chewed a certain number of times and then retrieved and measured with sieves of various mesh sizes, was used over the last half century as the standard diagnostic method of masticatory performance. 2,3 However, because of the drawbacks of this method, such as being complicated and time-consuming, other relatively simple methods using silicone impression materials, 4,5 bagged almonds, 6 chewing gum, 7−9 paraffin wax, 10 and gummy jelly 11,12 have been tried in recent years.…”

Clinical significanceThis study confirms that measuring glucose extraction from chewing gummy jelly is an effective way of objectively evaluating masticatory performance and can be easily used in actual clinical practie. AbstractPurpose: The purpose of this experiment was to investigate the effectiveness of examining masticatory performance by measuring glucose extraction from chewing gummy jelly. Methods:Twenty healthy subjects were asked to chew 2g of gummy jelly and 3g of peanuts for 10, 20, and 30 strokes respectively. The masticatory value as measured by the sieve method was then compared with the amount of glucose extraction from chewing gummy jelly. Results:The relationship between the amount of glucose extraction and the masticatory value was positive (r =0.475-0.850). Both the amount of glucose extraction and the masticatory value were lowest for the 10 chewing strokes and significantly increased for the 20 and 30 chewing strokes (glucose extraction F=1179.6, P <0.01; masticatory value F =605.0, P <0.01). The standardized glucose extraction for the 10, 20, and 30 chewing strokes was 0.17, 0.34, and 0.49 respectively, and increased proportionally. The standardized masticatory values for the 10, 20, and 30 chewing strokes were 0.28, 0.35, and 0.37 respectively, and increased logarithmically. Conclusion:From these results it was concluded that the masticatory performance as measured by the amount of glucose extraction from chewing gummy jelly is an effective indicator of masticatory function and has a high potential for clinical application.

“…Both natural and artificial food have been used as test materials in experiments determining the masticatory performance (Manly and Braley, 1950;Edlund and Lamm, 1980). A natural test food has the advantage that it is normally consumed, so that subjects are accustomed to it.…”

“…Several methods have been The higher the average value, the better the patient's masticatory efficiency n sample size a Repeated measures ANOVA suggested [25][26][27][28], most of which are based on the ability of food trituration measured by different graduated sieves. According to Nakasima et al [29], these methods are not standardized as food may change due to pH alteration and saliva.…”

Objectives To evaluate the change in masticatory efficiency and quality of life of patients treated with mandibular Kennedy class I removable partial dentures (RPDs) and maxillary complete dentures at the Department of Dentistry of the Federal University of Rio Grande do Norte. Materials and methods A total of 33 Kennedy class I patients were rehabilitated with maxillary complete dentures, and mandibular RPDs were selected for this non-randomized prospective intervention study. The patients had a mean age of 59.1 years. Masticatory efficiency was evaluated by colorimetric assay using fuchsin capsules. The measurements were conducted at baseline and 2 and 6 months after prosthesis insertion. Quality of life was evaluated using the Oral Health Impact Profile (OHIP-14) at baseline and 6 months after denture insertion. The Kolmogorov-Smirnov normality test was applied. Masticatory efficiency was evaluated by repeated measures ANOVA. Oral health-related quality of life was compared using the paired t test.Results There was no statistically significant difference in masticatory efficiency after denture insertion (p =0.101). Significant differences were found (p=0.010) for oral healthrelated quality of life. A significant improvement in psychological discomfort (p<0.01) and psychological disability (p<0.01) was observed. Mean difference value (95 % confidence interval) was 6.8 (3.8 to 9.7) points, reflecting a low impact of oral health on quality of life, considering the 0-56 range of variation of the OHIP-14 and a Cohen's d of 1.13. Conclusion According to the results of the present study, rehabilitation with Kennedy class I RPDs and complete dentures did not influence masticatory efficiency but improved oral health-related quality of life. Clinical relevance The association between the patient's quality of life and the masticatory efficiency is important for treatment predictability.
