“…Although there are many studies regarding the design and testing of various oral stents, there is no current research to test its durability using FEA method. In our FEA, the maximum values of human bite and tongue forces are 350 N and 65 N based other findings [9,10]. The results from the maximum human bite and tongue forces indicated that the total deformation value of our mouthpiece and tongue displacer were lower than 0.3 mm.…”

The primary treatment for head and neck cancer is radiotherapy, which can cause complications and effects, such as the ability to speak, taste, produce saliva, and swallow. An oral stent is an immobilization tool for minimizing the dose in the tongue (or hard palate) by locking the tongue position during radiation delivery. It can improve the treatment accuracy due to less uncertainty caused by tongue position uncertainty between treatment fractions. However, commercial oral stents are not widely adopted in developing countries due to their unaffordable price. This study aimed to design the universal oral stent (UOS) to achieve high efficiency, ease to use, and low-cost fabrication based on 3D printing technology. There were five experiments to evaluate the UOS design and fabrication versus the modified cut syringe, including finite element analysis (FEA), the usability test, the micro Vickers hardness test, single beam dose analysis, and dose calculation on treatment plan simulations. The proposed UOS design and fabrication presented a high capability to apply for clinical use.

“…Similar to tongue mobility, the etiology of phenomena remains unclear. In a recent report, Birk et al [46] concluded that maximum isometric tongue force in patients with OSA does not seem to differ from that observed in healthy subjects (although patients with OSA displayed stronger isometric tongue force, the figures were not significant). Yet, in that study, tongue force was measured differently: in an anterior/posterior direction in a protrusion task instead of the tongue elevation and lip compression tasks of our study.…”

“…In particular, children with reported sleep apnea displayed lower orofacial force in both the buccinator and the anterior or posterior genioglossus. This may contribute to airway collapse susceptibility at the tongue base, which is one of the underlying pathologies in OSA [46]. Such tongue base collapses are due to improper tongue position and volume or to a reduction of muscle tone during sleep [47,48].…”

Orofacial myofunctional disorders (OMD) and sleep-disordered breathing (SDB) may present as comorbidities. Orofacial characteristics might serve as a clinical marker of SDB, allowing early identification and management of OMD and improving treatment outcomes for sleep disorders. The study aims to characterize OMD in children with SDB symptoms and to investigate possible relationships between the presence of various components of OMD and symptoms of SDB. A cross-sectional study of healthy children aged 6–8 from primary schools was conducted in central Vietnam in 2019. SDB symptoms were collected using the parental Pediatric Sleep Questionnaire, Snoring Severity Scale, Epworth Daytime Sleepiness Scale, and lip-taping nasal breathing assessment. Orofacial myofunctional evaluation included assessment of tongue mobility, as well as of lip and tongue strength using the Iowa Oral Performance Instrument, and of orofacial characteristics by the protocol of Orofacial Myofunctional Evaluation with Scores. Statistical analysis was used to investigate the relationship between OMD components and SDB symptoms. 487 healthy children were evaluated, of whom 46.2% were female. There were 7.6% of children at high risk of SDB. Children with habitual snoring (10.3%) had an increased incidence of restricted tongue mobility and decreased lip and tongue strength. Abnormal breathing patterns (22.4%) demonstrated lower posterior tongue mobility and lower muscle strength. Daytime sleepiness symptoms were associated with changes in muscle strength, facial appearance, and impaired orofacial function. Lower strengths of lip and tongue or improper nasal breathing were more likely to be present in children with reported sleep apnea (6.6%). Neurobehavioral symptoms of inattention and hyperactivity were linked to anomalous appearance/posture, increases in tongue mobility and oral strength. This study demonstrates a prevalence of orofacial myofunctional anomalies in children exhibiting SDB symptoms. Children with prominent SDB symptoms should be considered as candidates for further orofacial myofunctional assessment.

Background. The tongue is a powerful muscular organ with a variety of functions and the ability to influence many systems of the human body, which is due to the peculiarities of its embryogenesis, the proximity of many anatomical structures, rich innervation and connection with many parts of the brain. Functional changes of the tongue muscles can be associated with various pathological conditions. Thus, systemic disorders secondarily involve the tongue, and local changes in the tongue (tongue dysfunction, tumors,changes in the mucous membrane in old age and with existing somatic diseases, obstructive sleep apnea syndrome and emotional can develop into systemic diseases. Tongue has embryological and functional relationship with the occipital region and the hyoid bone, which develop from the second gill arch. In addition, anatomically, the tongue is also interconnected with the hyoid bone and, therefore, with hyoid muscles and muscles of the mouth bottom. Aim. To determine the significance of the functional features of human tongue in the etiopathogenesis of dysfunctional states of the muscular, respiratory and other systems and the psycho-emotional sphere of the human body. Material and methods. Was analyzed the researchers results from available literature sources from the "Elibrary" and "Pubmed" platforms, including patents and scientific articles of domestic and foreign authors. Results. The paper presents data from literature sources on anatomical and functional relationships with human body systems. The correct physiological localization of the tongue in the oral cavity is described, the advantages of this position are given. Conclusions. It is well known that the tongue participates in speech formation, chewing, swallowing. However, the facts of the influence of the position and functional features of the tongue during breathing, the formation of structures of the maxillary system, the maintenance of posture and muscle balance of the human body, facial function, in the emotional sphere are interesting.
