“…[27][28][29][30][31][32] Several recent studies revealed the positive effects of teeth clenching on static balance. [10][11][12][13][14][15] However, it is suggested that teeth clenching during jump-landing may adversely affect dynamic balance control in this study. Previous studies indicate that teeth clenching affects the skeletal muscles of the limb, and contributes to stabilization of body orientation.…”

“…Several studies report the relationship between teeth clenching and static balance. [10][11][12][13][14][15] Fujino et al 11 investigated the effect of voluntary teeth clenching on static balance. They showed that voluntary teeth clenching contributed to stabilization of the postural stance perturbed transiently by electrical stimulation.…”

The aim of this study was to analyze the effect of teeth clenching on dynamic balance at jump landing. Twenty-five healthy subjects performed jump-landing tasks with or without teeth clenching. The first 3 trials were performed with no instruction; subsequently, subjects were ordered to clench at the time of landing in the following 3 trials. We collected the data of masseter muscle activity by electromyogram, the maximum vertical ground reaction force (vGRFmax) and center of pressure (CoP) parameters by force plate during jump-landing. According to the clenching status of control jump-landing, all participants were categorized into a spontaneous clenching group and no clenching group, and the CoP data were compared. The masseter muscle activity was correlated with vGRFmax during anterior jump-landing, while it was not correlated with CoP. In comparisons between the spontaneous clenching and the no clenching group during anterior jump-landing, the spontaneous clenching group showed harder landing and the CoP area became larger than the no clenching group. There were no significant differences between pre-and postintervention in both spontaneous clenching and no clenching groups. The effect of teeth clenching on dynamic balance during jump-landing was limited.Keywords: dynamic balance, teeth clenching, ground reaction force, center of pressure, electromyogramTeeth clenching is performed in a voluntary manner by the contraction of mandibular muscles. These muscles receive innervation from the motor area of the cerebral cortex, the same as skeletal muscles of the limbs.1 Recently, it has been reported that chewing activity has a positive effect on attention, mood improvement, and stress relief.2,3 Moreover, positive correlation between muscle strength of the skeletal muscles and teeth clenching was reported. Sasaki et al 4 reported that teeth clenching force had a positive correlation with isometric gastrocnemius muscle strength. A number of studies have demonstrated that voluntary teeth clenching facilitated the H-reflex in both the agonist and antagonist muscles of the lower limb, [5][6][7][8][9] suggesting that teeth clenching contributed to stabilization of body orientation by strengthening the skeletal muscles of the limb.There were also several reports that confirmed the oral motor activity relations on postural control, 10-15 revealing the superior effect of teeth clenching on body balance control against body sway. However, these pieces of research were subjected to static balance, and there were few reports that investigated the effect of teeth clenching on dynamic balance.Stabilization of dynamic balance is important for sport activity and injury prevention. Although the effects of teeth clenching on sport performance and injury prevention were investigated in several pieces of research, 16-18 they remain controversial. Additionally, the subsequent occlusion status (presence and force of teeth clenching) in various sports is also unknown. In this study, we investigated the occlusion status and the effect ...

“…The purpose of the present study was to investigate the effect of the electrical stimulation of the intra-oral tissues around a tooth on neck muscle activity (i.e., exteroceptive receptors for the neck muscles), applying the stimulation and recording techniques previously used for the ES response. However, because visual information influences -11 -the head posture control (Vacherot et al, 2007;Tardieu et al, 2009), all recordings were carried out with the eyes closed condition.…”

* The effect of intra-oral electrical stimulation on the dorsal neck muscle activity was investigated in healthy volunteers.* The electromyographic (EMG) activity was reduced around 50 ms after the painful intra-oral electrical stimulation on average 80 % compared to baseline level in all subjects.* Local anesthesia of the stimulus site resulted in smaller inhibition of the dorsal neck EMG activities and disappearance of the painful sensation evoked by the stimulation.-2 - AbstractObjective: To investigate the effect of painful electrical stimuli applied to intra-oral tissues around the teeth on the neck muscle activity in healthy humans.Methods: Electromyographic (EMG) responses of the dorsal neck muscles evoked by intra-oral electrical stimulation were recorded before and after local anesthesia to the stimulus site in 17 healthy volunteers.Results: Inhibition of dorsal neck muscle EMG activities on average 80% compared to baseline level was observed with a latency around 50 ms after the electrical stimulation before anesthesia, and the EMG activity inhibition decreased after anesthesia of the intra-oral stimulus site. The perceived intensity of the electrical stimuli as scored on a visual analogue scale (VAS) was 6.1 ± 0.4 cm before anesthesia and 1.5 ± 0.2 cm after anesthesia.Conclusion: Intra-oral stimulation can inhibit neck muscle activity. This modulation might be attributed mainly to nociceptive afferent nerves however, non-nociceptive fibers could also be responsible.Significance: Intra-oral information including nociceptive activity can inhibit neck muscle activity. From a clinical viewpoint, the present findings demonstrate the neural connectivity between the trigeminal region and the cervical region raising the possibility that orofacial pain conditions could influence head, neck and shoulder activity.-3 -

“…Together, they form a functional system denoted cranio-cervico-mandibular. Studies concerning this intimate connection have been designed in order to confirm that changes of posture of the head and of other body parts may lead to functional alteration of the masticatory system and vice versa [3][4][5][6][7][8] . It has been observed that the molar relation seems to play an important role in this connection and that certain malocclusion problems may be related to changes in head posture more than others 9 .…”

Conflict of interest: non-existentAccording to Grade et al. 2 , the temporomandibular joint (TMJ) represents the connection of the mandible to the base of the skull, which in turn presents muscle and ligament connections with the cervical region. Together, they form a functional system denoted cranio-cervico-mandibular. Studies concerning this intimate connection have been designed in order to confirm that changes of posture of the head and of other body parts may lead to functional alteration of the masticatory system and vice versa [3][4][5][6][7][8] . It has been observed that the molar relation seems to play an important role in this connection and that certain malocclusion problems may be related to changes in head posture more than others 9 . Several authors have studied the presence of changes in head posture in patients with malocclusion. Some of them have stated that patients with class II and class III malocclusion present changes in head posture on the sagittal plane 1,[10][11][12][13] , as well as on the frontal and transverse plane [13][14][15] . Although there is a consensus about the connection existing between the stomatognathic and ABSTRACT Purpose: this study investigates whether there is a difference in head posture between groups with different dentofacial deformities (class II and class III) and a group with no deformity. Method: 25 volunteers aged from 16 to 40 year old took part in the study. Ten patients had a diagnosis of class II dentofacial deformity, 15 had a diagnosis of class III skeletal deformity, and 15 healthy volunteers matched for sex and age to the group with deformity were used as a control group. Head posture was first checked, followed by evaluation through postural photography (photogrammetry). Results: there was no significant difference (p>0.05) between groups regarding postural evaluation by photogrammetry. However, postural evaluation using clinical inspection, revealed anterior head posture among subjects with class II dentofacial deformity compared to subjects with class III deformity (p = 0.001) and to control group (p = 0.001). The percentage of class II dentofacial deformity subjects with neutral head posture was also lower compared to class III dentofacial deformity (p = 0.008) and to control group (p = 0.001). Conclusion: subjects with class II dentofacial deformity may show anteriorization of the head. There is no influence of the deformity on the increase or reduction of the head-neck angle when analyzed by photogrammetry.
