“…In our study, this variable was only intended to measure the vertical dimension from the middle to the lower third of face. In addition, in this investigation, the repetition of the main experiment in 10 subjects demonstrated the repeatability of positioning the subjects in ''natural head position'', without any inclination of the body column that was shown to create an adaptation of the cervical column (through a change in the atlantocervical angle) (Zepa et al, 2000) that could result in a different electric activity of the SCM and trapezius between the two recordings. In this study we did not observe any electrical activity of SCM muscle that was more than the noise level.…”

“…Finally, in the analysis of the orthopedic literature, Floman [53] indicated a possible connection between thoracic scoliosis and restricted head motion in a report of 6 patients. However, it has not been clarified whether such a restriction in head motion had a secondary influence on occlusion.…”

BackgroundIdiopathic scoliosis is a deformity without clear etiology. It is unclear wether there is an association between malocclusion and scoliosis. Several types of occlusion were described in subjects with scoliosis, mostly case-reports.ObjectivesThe aim of this review was to evaluate the type of occluslins more prevalent in subjects with scoliosisSearch strategyAll randomised and controlled clinical trials identified from the Cochrane Oral Health Group Trials Register, a MEDLINE search using the Mesh term scoliosis, malocclusion, and relevant free text words, and the bibliographies of papers and review articles which reported the outcome of orthodontic treatment in subjects with scoliosis that were published as abstracts or papers between 1970 and 2010.Selection criteriaAll randomised and controlled clinical trials published as full papers or abstracts which reported quantitative data on the outcomes malocclusion in subjects with scoliosis.Data collection and analysisData were extracted without blinding to the authors, age of patients or type of occlusion.Main resultsUsing the search strategy eleven observational longitudinal studies were identified. No randomized clinical trials were recorded. Twenty-three cross-sectional studies were recorderd, and the others studies were reviews, editorials, case-reports, or opinions. The clinical trials were often not controlled and were about the cephalometric evaluation after treatment with the modified Milwuakee brace, followed by the orthodontic treatment of the class II relationship with a functional appliance. Clinical trials also included the study of the associations between scoliosis and unilateral crossbite, in children with asymmetry of the upper cervical spine. This association was also investigated in rats, pigs and rabbits in clinical trials. The other associations between scoliosis and occlusion seems to be based only on cross-sectional studies, case-reports, opinions.Authors' conclusionsBased on selected studies, this review concludes that there is plausible evidence for an increased prevalence of unilateral Angle Class II malocclusions associated with scoliosis, and an increased risk of lateral crossbite, midline deviation in children affected by scoliosis. Also, documentation of associations between reduced range of lateral movements and scoliosis seem convincing. Data are also mentioned about the association between plagiocephaly and scoliosis.

Background:In the past few years, growing interest was given to the relationship between the dental occlusion and the body balance. While most research focused on this relationship at static conditions, it is evident that the contribution of the sensory information for balance control is different depending on the environmental constraints. Research question:The aim of the present paper was to elucidate whether the stomatognathic system (SS) contributes differently on body balance regulation according to the presence of external disturbances. Methods:Literature regarding the different sources involved in the proprioceptive information to the SS was reviewed. The influence of dental occlusion on balance control at different external environments was then explored. Results:The main findings are: (a) a plausible evidence between the masticatory and cervical muscles can be described; (b) a reciprocal connection between the trigeminal and vestibular nuclei supports the influence of the SS on body balance; (c) traditionally, research involving the relationship between the SS and balance control has focused on strictly controlled situations, thus, ignoring the sensory reweighting which occurs depending on the external disturbances; and (d) the afferences of dental occlusion for balance control seem strengthened when more difficult conditions are present. Conclusion:Results of the present review suggest that afferent signals from dental occlusion effectively contribute to balance control when more external perturbations are present, that is unstable support surface, fatigue and tasks being performed.However, more studies are needed to elucidate the mechanisms by which dental occlusion may influence balance control focusing on different external environments.
