Abstract
PURPOSE This study determined the contributions of the anterior and posterior tongue regions in tongue pressure generation during regular saliva swallows (SSs) and effortful swallows (ESs) completed under two different instructions. The association between tongue pressure and perceived effort to swallow was also examined. METHOD Forty healthy adults without swallowing disorders participated in this study, divided into two age groups: 20 younger (Mage = 21.95 years, SD = 4.43) and 20 older (Mage = 70.10 years, SD = 4.30). Simultaneous data acquisition involved submental surface electromyography, tongue manometry, and a visual analog scale across swallowing conditions (SS, ES with tongue emphasis, and ES with pharyngeal squeezing). The main outcome measures were tongue pressure during swallowing and perceived effort to swallow. RESULTS Overall tongue pressure during ESs with tongue emphasis and with pharyngeal squeezing was greater than that during SSs (R2 = .78, p < .001). Moreover, tongue pressure during the ES with tongue emphasis was greater than that during the ES with pharyngeal squeezing (t = 25.63, p < .001). The posterior tongue region generated more pressure during SSs (R2 = .64, p < .001) and the ES with tongue emphasis (R2 = .55, p < .001) than the anterior tongue. Finally, a positive correlation was found between perceived effort and tongue pressure during swallowing (r = .75, 95% CI [0.72, 0.77]). CONCLUSIONS Tongue pressure generation was affected by the type of instruction used to elicit ESs, and the posterior tongue showed relatively greater pressure contributions than the anterior tongue for ESs with tongue emphasis and SSs. Furthermore, age-related declines in pressure generation during swallowing were not evidenced in this study, underscoring the ability of healthy older individuals to appropriately modulate lingual pressure during ESs. Last, our results showed that the visual analog scale is a simple tool for rating swallowing effort during ESs, supporting its potential clinical use to train ESs.

Relationship between maximal isometric tongue pressure and limit of fracture force of gels in tongue squeezing. J Oral Rehabil 2024; 51:574-580. [PMID: 37964441 DOI: 10.1111/joor.13627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 09/27/2023] [Accepted: 11/06/2023] [Indexed: 11/16/2023]
Abstract
BACKGROUND There is no clear objective indicator for selecting soft foods that are required for food bolus formation in older people with impaired oral function. OBJECTIVE This study aimed to investigate the relationship between maximal isometric tongue pressure (MITP) and the mechanical properties of gels that can be crushed by the tongue. METHODS This study included 65 healthy participants aged 22-96 (young group; 15 males, 15 females; older dentate group; 7 males, 8 females; older edentulous group; 10 males, 10 females). MITP was measured by the balloon-probe device. Agar gel with 10 different kinds of fracture force from 10N to 100N was used. The limit of fracture force of gels (LFFG) that were crushed by the tongue was measured by the up-and-down method. In the older edentulous group, two items were measured with and without dentures. Spearman's rank correlation coefficient was used to evaluate the relationship between MITP and LFFG in each group (p < .05). RESULTS There were positive correlations between MITP and LFFG in all groups (overall groups: rs = .66, young group: rs = .46, older dentate group: rs = .61, older edentulous group with dentures: rs = .60, older edentulous group without dentures: rs = .47). CONCLUSION MITP and LFFG were positively correlated in young, older dentate and older edentulous groups, suggesting that MITP has the potential to be an objective indicator of the range of mechanical properties of soft food that can be crushed by the tongue.

Abstract
Dysphagia has been classified as a “geriatric syndrome” and can lead to serious complications that result in a tremendous burden on population health and healthcare resources worldwide. A characteristic age-related change in swallowing is defined as “presbyphagia.” Medical imaging has shown some changes that seriously affect the safety and efficacy of swallowing. However, there is a general lack of awareness of the effects of aging on swallowing function and a belief that these changes are part of normal aging. Our review provides an overview of presbyphagia, which has been a neglected health problem for a long time. Attention and awareness of dysphagia in the elderly population should be strengthened, and targeted intervention measures should be actively implemented.

Abstract
BACKGROUND The oropharyngeal dysphagia is an underestimated symptom with various causes in the geriatric population. Clinical presentation is often insidious and dysphagia symptoms are seldomly mentioned by elderly patients although causing many life-threatening complications. The aim of this work was to introduce an easy applicable tool to be used by the caregivers and general practitioners for screening of dysphagia in geriatrics for early detection of at risk individuals. METHODS A sample of 200 Egyptian Arabic-speaking elderly patients (65 years or older) not complaining of dysphagia was recruited from nursing homes in Greater Cairo Area. They or their caregivers completed the designed screening tool, including; the designed questionnaires of dysphagia manifestations and eating habits. General, oral motor and bedside evaluation were also performed. In addition to filling in the EAT10 questionnaire and FEES that was performed for only suspected cases for the purpose of validation of the screening tool. RESULTS The dysphagia manifestations questionnaire was significantly correlated with EAT 10 with p value of 0.001. It was correlated in some of its aspects with FEES showing quite reliability with p values' range between 0.012 and 0.044. The Questionnaire of eating habits reliability of r- value of 0.568 slightly exceeding EAT10 reliability of r -value of 0.721 in the subjects under study. The cutoff point of total score of the dysphagia manifestations was > 5, with a sensitivity of 17.65% & a specificity of 94.20%. The cutoff point of total score of the bedside evaluation was ≤ 1 with a sensitivity of 66.9% & a specificity of 56.9%. CONCLUSION the use of this easy applicable screening tool managed to suspect and later on diagnose cases with oropharyngeal dysphagia in non-complaining aging subjects.

Abstract
Videofluoroscopic analyses of swallowing in survivors of traumatic cervical spinal cord injury (tCSCI) have been largely limited to case reports/series and qualitative observations. To elucidate the disrupted physiology specifically underlying dysphagia post-tCSCI, this prospective observational study analyzed videofluoroscopic swallow studies (recorded at 30 frames per second) across 20 tCSCI survivors. Norm-referenced measures of swallow timing or displacement, and calibrated area measures of laryngeal vestibule closure (LVC) were explored in relation to the severity of aspiration or pharyngeal residue. Videofluoroscopic performance was compared by injury level, surgical intervention, tracheostomy status, and in relation to clinical bedside assessments. Reduced pharyngeal constriction, delayed hyoid elevation, and impaired LVC characterized post-tCSCI dysphagia. Reduced extent of hyoid excursion and of pharyngoesophageal segment (PES) opening were not as prominent, only present in approximately half or less of the sample. Ten participants aspirated and 94% of aspiration events were silent. Severity of aspiration significantly correlated with pharyngeal constriction and prolonged pharyngeal transit times. Post-swallow residue correlated with delayed PES distention/closure and prolonged pharyngeal transit. Clinical inference regarding the integrity of the pharyngeal phase at bedside was limited; however, EAT-10 scores demonstrated promise as an adjuvant clinical marker of post-tCSCI dysphagia. This exploratory study further describes the pathophysiology underlying post-tCSCI dysphagia to promote deficit-specific rehabilitation and functional recovery.

Effects of Tongue-Strengthening Exercise on Tongue Strength Reserve and Detraining Effects among Healthy Adults: A Randomized Controlled Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116878. [PMID: 35682461 PMCID: PMC9180874 DOI: 10.3390/ijerph19116878] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Revised: 06/01/2022] [Accepted: 06/02/2022] [Indexed: 12/10/2022]
Abstract
Introduction: Tongue strength reserve is the difference between the maximum isometric pressure (MIP) and swallowing pressure of the tongue. People with decreased tongue strength reserve may have a higher risk of presbyphagia or dysphagia. Thus, this study explored the effects of tongue strengthening exercise (TSE) on tongue strength reserve and detraining effects in healthy adults. Materials and Methods: In total, 102 healthy volunteers without any reported history of speech or swallowing deficits were recruited and assigned to experimental (n = 50) and control groups (n = 52). Exercises in the experimental group consisted of compressing an air-filled bulb between the tongue and hard palate for 30 min a day, 5 days a week, for 8 weeks. Thereafter, the experimental group underwent a 4-week detraining period. Results: Following the TSE training, posterior tongue strength reserve (F = 4.92, p = 0.029) of the experimental group was significantly higher than that of the control group. No significant detraining effects were observed on the MIP and swallowing pressure from 4 weeks after the completion of TSE training. Conclusions: According to the study results, TSE may be an effective approach for improving swallowing function.

Abstract
Background The relationship between tongue pressure and masticatory performance during the mixed dentition period in cases of Class II malocclusion has not been clarified. The aim of this study was to determine differences in tongue pressure-related factors, including maxillofacial morphology and masticatory performance, between Class I and Class II malocclusions during the mixed dentition period. Methods A total of 56 children with Class I malocclusion (12 boys, 16 girls) or Class II malocclusion (16 boys, 12 girls) with mixed dentition were included in the present study. Height, body weight, hand grip strength, maximum occlusal force, maximum tongue pressure, masticatory performance, and the number of decayed, missing, and filled teeth were measured in all participants. Their lateral cephalograms were also evaluated. The means of all measurements were compared between Class I and Class II malocclusions. Pearson’s correlation coefficients were used to determine associations between maximum tongue pressure and other variables for each type of malocclusion. Results The maximum tongue pressure, hand grip strength, and maximum occlusal force in the Class II malocclusion group were significantly lower than those in the Class I malocclusion group (all, p < 0.05). The maximum tongue pressure was significantly positively correlated with hand grip strength, maximum occlusal force, masticatory performance, and SNB (sella, nasion, B point) angle in the Class I group (all, p < 0.05), and with height, body weight, and labial inclination of the central incisors in the Class II group (all, p < 0.05). Conclusions The maxillofacial morphometric factors associated with tongue pressure were clearly different between cases of Class I and Class II malocclusion with mixed dentition. Masticatory performance and tongue pressure were significantly positively correlated in cases of Class I malocclusion, but not in cases of Class II malocclusion.

Abstract
Swallowing is a neuromuscular process that involves a complex sequence of sensorimotor events, which are executed to efficiently and safely transport food and liquid from the mouth to the stomach. Safe oropharyngeal swallowing involves the activation, modulation, and coordination of oral, pharyngeal, laryngeal, and esophageal structures and musculature. Impaired or atypical patterns of swallowing are considered characteristic of a swallowing disorder, otherwise referred to as dysphagia, and affect the performance of all stages, i.e., oral preparatory, oral transit, pharyngeal, and esophageal. Lingual and jaw musculature play critical roles in mediating swallowing function, particularly during the oral preparatory and oral transit stages. This current study presents an adapted simple, economical, and clinically relevant protocol that may be used to quantify lingual and jaw movement in healthy and disordered swallowing, and thus track physiological changes in lingual and jaw musculature over time in individuals with dysphagia due to neurodegenerative diseases.Jaw ROM tasks, adapted from [1,2], were adapted and utilized to measure the jaw during three postures: opening, lateralization, and protrusion. Adapting a scale developed by Lazarus and colleagues [3], objective lingual ROM values were obtained using the TheraBiteⓇ tool [4] and categorized according to functional status. Upon methodological adaption and collation of lingual ROM and jaw ROM tasks, a comprehensive set of images clearly depicting each procedural task and a clinically friendly form were developed to guide data collection for research and clinical use.

Abstract
Measures of tongue strength and endurance using the Iowa Oral Performance Instrument (IOPI) may have diagnostic utility during clinical swallowing evaluations for persons with Parkinson's disease (PwPD). Thus, the objective was to systematically analyze the existing literature comparing IOPI values of tongue strength and endurance between age- and sex-match pairs of PwPD and healthy adults as well as across disease stages. A systematic review of 12 databases and Google Scholar identified five peer-reviewed articles published in English (1990-2019) that compared tongue strength and/or endurance between PwPD and controls. Individual-level data were published in two studies and provided by authors for three studies. Study appraisal included the NIH Quality Assessment Tool and STROBE checklists. Limited data for posterior tongue pressures restricted meta-analyses to anterior pressures. Meta-analyses of group means indicated reduced tongue strength across 106 matched pairs (p < .001, I2 = 0%) and a trend for reduced endurance across 41 matched pairs (p = .07, I2 = 54%). Participant-level analyses found reduced strength (96 pairs, p < .001) and endurance (41 pairs, p = .011) secondary to PD. Tongue strength (n = 68), but not endurance (n = 41), inversely correlated with disease stage when controlling for age (p ≤ .018). Overall, clinicians should be aware that reduced anterior tongue strength and endurance are as follows : expected in approximately one-third and one-fourth of PwPD, respectively, and reduced anterior tongue strength may manifest as early as Hoehn and Yahr stage 2 with continual decline as disease progresses. Further investigation is warranted regarding the relation among tongue strength, tongue endurance, and swallowing physiology as well as applications of tongue pressure training within dysphagia rehabilitation for PwPD.

Abstract
The study examines the effects of age and Parkinson's disease on lingual and jaw function in neurotypical adults, as well as persons with Parkinson's Disease. Preliminary results provide reference measures in these populations and support the systematic collection of objective data regarding lingual strength, lingual range of motion, and jaw range of motion in clinical populations. The application of this clinically meaningful protocol also provides a means to track physiological changes over time in order to maximize the results of rehabilitative efforts to restore swallow function.

Abstract
This study collected 11 parameters regarding the labial and lingual strength for maximum isometric and swallowing tasks among 150 healthy Chinese adults in Taiwan. Measurements were performed using the Iowa Oral Performance Instrument (IOPI). All of the labial and lingual strength parameters were measured three times. The maximal value of three trials represents the pressure of every parameter. The overall mean (±standard deviation) and maximum isometric pressures of the lips, anterior tongue, and posterior tongue were 24.81 ± 5.64, 55.95 ± 14.13, and 53.23 ± 12.24 kPa, respectively. The mean value of posterior tongue strength was less than that of the anterior tongue by approximately 5%. The percentages of maximum isometric tongue pressure during the swallowing of saliva and water were 85% and 80% for the anterior tongue and 90% and 81% for the posterior tongue, respectively. The average endurances for the anterior tongue and posterior tongue were 13.86 ± 7.08 and 10.06 ± 5.40 s, respectively. The maximum isometric pressures were greater than both the saliva and water swallowing pressures, and the saliva swallowing pressures were greater than the water swallowing pressures. A value of 33 kPa in maximum isometric pressure could serve as a demarcation of weak tongue strength for healthy Chinese adults. As for the repeated trials of labial and lingual strength, there were no statistically significant differences for any of the pressures obtained from the 11 labial and lingual strength parameters. The normative data can be used for the objective assessment of labial and lingual strength in healthy Chinese adults.

Abstract
Background: Post-stroke dysphagia is characterized by reduced corticolingual excitability and lingual pressure; however, it remains unknown if transcranial magnetic stimulation (TMS) directly facilitates lingual pressure generation.Objectives: To explore optimal procedures for single pulse TMS using neuronavigation to evoke lingual pressure in intact and disrupted neural networks.Methods: Using co-registered functional magnetic resonance imaging, stimulation sites were determined for five healthy adults (Mage = 67) and four stroke survivors with dysphagia and reduced tongue strength (Mage = 66). Evoked lingual pressures were sampled across 45-65% of maximum stimulator output. Healthy participants repeated TMS with a bite block to isolate lingual pressure from off-target stimulation of mandibular elevators.Results: Only one functionally-guided stimulation site fell within previously reported optimal lateral (8-11cm) and anterior (2-4.25cm) coordinates. Lingual pressure was stable prior to pulse and increased linearly with intensity for both groups (p = .005). Post-stroke active motor thresholds were elevated compared to healthy adults (p = .025). Lingual pressure latency remained stable across intensities (p > .05). Jaw stabilization via bite block reduced the mean magnitude of evoked lingual pressure by approximately 16%.Conclusions: Single pulse TMS directly evokes higher lingual pressure and can define motor thresholds in intact and disordered corticolingual pathways. Stimulation sites using neuronavigation in healthy adults and stroke survivors largely differed from external coordinates in the literature that were predominantly established in young adults. Procedures to investigate motor thresholds for lingual pressure generation are proposed. The therapeutic role of TMS to address post-stroke deficits in lingual pressure and corticolingual excitability warrants continued investigation.

Purpose Dysphagia in Parkinson's disease (PD) is a major cause of depression and reduced quality of life (QOL). PD-related dysphagia often involves lingual dysfunction and weak pressure generation. The relation of disordered lingual pressure generation to swallowing-related QOL in persons with PD remains unknown. Method Twenty-four persons with idiopathic PD completed the Swallowing Quality of Life (SWAL-QOL) questionnaire and an evaluation of anterior and posterior tongue strength. Peak pressures were compared to age- and sex-matched controls. The magnitude of and latency to peak pressure were explored in relation to SWAL-QOL scores. Results Persons with PD exhibited significant anterior (p = .019) but not posterior (p = .081) lingual weakness compared to controls. Persons with PD and reduced anterior tongue strength (< 42 kPa) reported lower SWAL-QOL total (p = .043), extended eating durations (p = .025), and a reduced desire to eat (p = .020). Prolonged latency to peak anterior pressure in PD inversely correlated with SWAL-QOL total (r = -.750, p < .001) and served as a significant, independent predictor of 67% of the variance in SWAL-QOL total when controlling for age, sex, and disease stage. Conclusion Overall, SWAL-QOL scores declined in the presence of lingual pressure dysfunction. Lingual weakness and prolonged pressure building patterns secondary to PD, especially of the anterior tongue, may represent clinically relevant disruptions to mealtime behaviors that undermine swallowing-related QOL. These preliminary findings support further investigation of lingual pressure patterns in PD to help identify debilitating dysphagia and develop treatment strategies.

Abstract
Purpose Dysphagia treatments to address the deterioration of oropharyngeal and respiratory functions in Parkinson's disease (PD) are few and rarely researched in persons with complex medical histories. This research note explored the effects of an intensive exercise-based swallowing program (ISP) that incorporated lingual and respiratory exercises for persons with PD and complex medical history. Method A single-case experiment was conducted across a 4-week ISP of lingual training and expiratory muscle strengthening for 2 participants (67-year-old man and 61-year-old woman). Probes included tongue strength and maximum expiratory pressure. Generalization measures included the Mann Assessment of Swallowing Ability (Mann, 2002), Timed Water Test (Hughes & Wiles, 1996), Repetitive Saliva Swallow Test (Oguchi et al., 2000), Functional Oral Intake Scale (Crary, Carnaby Mann, & Groher, 2005), and Swallowing Quality of Life questionnaire (McHorney et al., 2002). Results Gains occurred in tongue strength and maximum expiratory pressure (p ≤ .002) with large effect sizes (d ≥ 1.3) as well as Mann Assessment of Swallowing Ability and Timed Water Test performance. Repetitive Saliva Swallow Test performance and Functional Oral Intake Scale improved for 1 participant, whereas the other maintained function. Swallowing Quality of Life questionnaire remained largely unchanged; however, participants indicated they became more aware of their swallowing difficulties at posttreatment. Conclusions Persons with PD and complex medical history demonstrated increased lingual and expiratory muscle strength following a brief intensive program, which further generalized to select clinical swallowing measures. Findings suggest an overall positive and potentially additive or synergistic effect of an ISP. Future research may refine optimal candidacy and regimens for ISPs, which may help to maximize clinically meaningful returns, especially considering the increased demands of an intensive program.

Modulation of Tongue Pressure According to Liquid Flow Properties in Healthy Swallowing. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2019; 62:22-33.

Abstract
Purpose During swallowing, the tongue generates the primary propulsive forces that transport material through the oral cavity toward the pharynx. Previous literature suggests that higher tongue pressure amplitudes are generated for extremely thick liquids compared with thin liquids. The purpose of this study was to collect detailed information about the modulation of tongue pressure amplitude and timing across the range from thin to moderately thick liquids. Method Tongue pressure patterns were measured in 38 healthy adults (aged under 60 years) during swallowing with 4 levels of progressively thicker liquid consistency (International Dysphagia Diet Standardisation Initiative, Levels 0 = thin, 1 = slightly thick, 2 = mildly thick, and 3 = moderately thick). Stimuli with matching gravity flow (measured using the International Dysphagia Diet Standardisation Initiative Flow Test; Cichero et al., 2017 ; Hanson, 2016 ) were prepared both with/without barium (20% weight per volume concentration) and thickened with starch and xanthan gum thickeners. Results After controlling for variations in sip volume, thicker liquids were found to elicit significantly higher amplitudes of peak tongue pressure and a pattern of higher (i.e., steeper) pressure rise and decay slopes (change in pressure per unit time). Explorations across stimuli with similar flow but prepared with different thickeners and with/without barium revealed very few differences in tongue pressure, with the exception of significantly higher pressure amplitudes and rise slopes for nonbarium, starch-thickened slightly and mildly thick liquids. Conclusions There was no evidence that the addition of barium led to systematic differences in tongue pressure parameters across liquids with closely matched gravity flow. Additionally, no significant differences in tongue pressure parameters were found across thickening agents. Supplemental Material https://doi.org/10.23641/asha.7616537.

Abstract
PURPOSE The aim of this study was to clarify the effects of fitting palatal augmentation prosthesis (PAP) on the swallowing function for the patients in rehabilitation hospital. METHODS The subjects included 18 elderly hospitalized patients whose body mass index was <18.5kg/m2. All subjects wore maxillary complete denture. During a videofluoroscopic examination in which the patients were asked to swallow, post-swallowing pyriform sinus residue was detected. The subjects' maxillary dentures were then modified into PAPs by recording tongue movement in the palatal region. The resulting swallowing dynamics were evaluated qualitatively and quantitatively before and after fitting the PAP. RESULTS We found that fitting the PAP resulted in the resolution of aspiration in two patients and disappearance of pharyngeal residue in three. The pharyngeal delay and transit times were significantly shortened. CONCLUSIONS These results demonstrated that PAPs could be beneficial treatment devices that may reduce post-swallowing pharyngeal residue formation due to decreased muscle strength.

Abstract
Background Tongue plays an important part in oral and maxillofacial system. Measurement of tongue pressure helps to evaluate the performance of tongue movement. Objectives To establish a system for measuring tongue pressure against hard palate and to preliminarily explore pressure distribution of individual normal occlusions and the relationship with dental arch form. Methods A total of 19 volunteers of individual normal occlusions out of 189 dental students met inclusion criteria (nine males, ten females, aged 25.53 ± 0.96 years). A force‐sensing resistor device was used to measure tongue pressure at rest and functional state (swallowing). We observed tongue pressure of four channel (anterior, posterior and lateral sides of hard palate) in sitting, supine position and swallowing. We analysed pressure differences according to gender and explored correlation relationship between tongue pressure and dental arch width and length using 3D digital maxillary image. Results In rest, tongue pressure against hard palate increased from front to back in both sitting and supine position, without gender differences. When swallowing saliva, the pressure at lateral sides of females was found significantly higher than that of males. Bivariate correlation analysis revealed duration of swallowing was positively correlated with BMI and weight at posterior region and positively correlated with palatal length at anterior palate. The greater the dental arch width, the smaller the pressure of swallowing in the anterior and lateral region. Conclusion In rest, there was consistent pressure of tongue against hard palate. The pressure increased significantly during swallowing, especially in females. Tongue pressure was related to dental arch length, width, BMI and weight.

Abstract
Dysphagia in older adults is a challenging problem and necessitates a team approach. The key to effective management is recognition. Patients tend to dismiss their symptoms as normal aging; therefore, early diagnosis depends on the diligence of the primary care doctors. No diagnostic technique can replace the benefits of a thorough history, with a detailed understanding of nutritional status and aspiration risk. Although one of the main goals in management is to ensure safe swallowing, the impact of a nonoral diet on the quality of life of patients should not be underestimated.

Abstract
The aims of the present study were to evaluate whether there are significant differences in masticatory performance by gender and dental stage. We also determined the factors directly associated with the masticatory performance in children, and those directly associated with masticatory performance in young adults. The study included 180 subjects, ranging in age from 6 to 12 years or 20 to 33 years. The subjects were divided into three groups according to the Hellman developmental stage (III A, III B, or VA); the groups were the subdivided according to gender. The body mass index (BMI), maximum tongue pressure, and sum of decayed, missing, and filled teeth (DMFT) were determined in all subjects. To investigate masticatory performance, the total number and maximum projected area of chewed particles of the jelly materials were measured. Masticatory performance had the highest values at Stage VA in both males and females. Regarding the maximum tongue pressure in females, Stage III B had the highest value of all stages. Multiple regression analysis showed that masticatory performance was associated with DMFT index, maximum tongue pressure, and BMI in children. Among young adults, masticatory performance was associated with DMFT index and maximum tongue pressure. Better masticatory performance is directly associated with better dental status, a higher BMI, and tongue pressure in schoolchildren. Additionally, masticatory performance was well-correlated with tongue pressure in young adults, although maximum tongue pressure reached its peak before Stage VA in females. We suggest that females need training with respect to tongue pressure, by the mixed dentition stage.
