The stomatognathic system includes the relationship between teeth, masticatory muscles and temporomandibular joints with its relation with body and head posture. Aim of the study: This Systematic review is to research the relationship between occlusion and body posture. Materials and methods-Study design: This is a literature systematic review which is done after collecting more than 10 previous papers. Inclusion criteria: Papers explaining dental occlusion in details and its correlation with body and head posture. Exclusion criteria: Papers about occlusion focusing on occlusal splints and lab work. Conclusion: There is a strong relation between dental occlusion class, head, and body posture through PDL and the trigeminal nerve in the brain. Accordingly, the occlusion affects the posture and, more importantly, the position of the condyle in the temporal fossa. It was always believed that condyle position comes first then the occlusion, but it is the other way around.

“…Children and adolescents with malocclusion experience substantial psychological discomfort and a negative impact on their oral health-related quality of life ( Chen et al, 2015 ; Bittencourt et al, 2017 ). Young subjects with malocclusions present with poor responsiveness to the pain-relieving effects of relaxation ( Ruscheweyh et al, 2015 ). Orthodontic patients who require surgical treatment display high levels of anxiety and depression ( Hino et al, 2022 ).…”

Malocclusion impairs cognitive behavior via AgRP signaling in adolescent mice

IntroductionOcclusal disharmony induced by deteriorating oral health conditions, such as tooth loss and decreased masticatory muscle due to sarcopenia, is one of the causes of cognitive impairment. Chewing is an essential oral function for maintaining cognitive function not only in the elderly but also in young people. Malocclusion is an occlusal disharmony that commonly occurs in children. The connection between a decline in cognitive function and malocclusion in children has been shown with chronic mouth breathing, obstructive sleep apnea syndrome, and thumb/digit sucking habits. However, the mechanism of malocclusion-induced cognitive decline is not fully understood. We recently reported an association between feeding-related neuropeptides and cognitive decline in adolescent mice with activity-based anorexia. The aim of the present study was to assess the effects of malocclusion on cognitive behavior and clarify the connection between cognitive decline and hypothalamic feeding-related neuropeptides in adolescent mice with malocclusion.MethodsFour-week-old mice were randomly assigned to the sham-operated solid diet-fed (Sham/solid), sham-operated powder diet-fed (Sham/powder), or malocclusion-operated powder diet-fed (Malocclusion/powder) group. We applied composite resin to the mandibular anterior teeth to simulate malocclusion. We evaluated cognitive behavior using a novel object recognition (NOR) test, measured hypothalamic feeding-related neuropeptide mRNA expression levels, and enumerated c-Fos-positive cells in the hypothalamus 1 month after surgery. We also evaluated the effects of central antibody administration on cognitive behavior impairment in the NOR test.ResultsThe NOR indices were lower and the agouti-related peptide (AgRP) mRNA levels and number of c-Fos-positive cells were higher in the malocclusion/powder group than in the other groups. The c-Fos-positive cells were also AgRP-positive. We observed that the central administration of anti-AgRP antibody significantly increased the NOR indices.DiscussionThe present study suggests that elevated cerebral AgRP signaling contributes to malocclusion-induced cognitive decline in adolescents, and the suppression of AgRP signaling can be a new therapeutic target against cognitive decline in occlusal disharmony.

Effects of stress and relaxation on pain perception in subjects with pain‐free occlusional disharmony compared with healthy controls

Abstract: There is evidence for the presence of sensitization of the nociceptive system in subjects with occlusal disharmony. Possibly, deficient inhibition of extratrigeminal and trigeminal pain perception by relaxation might contribute to the development of TMD or other chronic pain disorders.
