“…Of note, while no other malocclusal trait or Helkimo Index showed significant relationships with any of the postural parameters, an increased overbite was correlated with better outcome of the Fukuda stepping test ( Table 6). The present findings would reinforce the hypothesis that correlations between stomatognathic systems and body posture can be detected experimentally; however, these appear to be weak and probably have little clinical meaning (2,8,14,16). A possible explanation for the low degree of relationships seen for trunk asymmetry (Table 5) might derive from the concept that the stomatognathic system can induce modifications that would probably be limited to the cervical region (33), so an altered head and neck posture might be responsive for the limited body-posture imbalances seen herein.…”

“…In particular, potential effects on whole-body posture have been investigated for dental (3)(4)(5)(6) and skeletal (7,8) malocclusion, and for temporomandibular disorders (TMDs) (9)(10)(11)(12)(13)(14)(15). However, in spite of these previous studies, most of the information available to date remains inconclusive, and recent reviews have reported contrasting conclusions in favour of (1) and against (2,16) clinically significant correlations. The few studies that have been specifically performed on dental malocclusion or TMDs have been hampered by the limited number of subjects included (5,10) and by imbalances between the study groups (5,9,11,15,17).…”

Whether there are correlations between the stomatognathic system and body posture remains controversial. Here, we have investigated whether malocclusal traits and having a Helkimo Index ≥ 5 show detectable correlations with body-posture alterations in children and young adults. A total of 1178 11- to 19-year-old subjects were divided into four groups: (i) controls; (ii) malocclusion; (iii) Helkimo Index ≥ 5 and (iv) malocclusion + Helkimo Index ≥ 5. Dental occlusion assessment included the following: overbite, overjet, posterior crossbite, scissorbite, mandibular crowding and dental class. Subsequently, body-posture assessments were performed through static analyses of body inclination and trunk asymmetry, and according to the dynamic Fukuda stepping test. Univariate and multivariate statistical analyses were performed. Although at the univariate level both the trunk asymmetry and Fukuda stepping test showed significant differences among the groups, the multivariate level revealed that age and gender were mostly responsible for this. The only significant correlation that was seen was for the malocclusion + Helkimo Index ≥ 5 group: these subjects had a positive (worse) trunk asymmetry and a negative (better) Fukuda stepping test performance. At the further multivariate analyses of each single malocclusal trait ⁄Helkimo Index ≥ 5 (irrespective of the groups), only an increased overbite showed a statistically significant association with a slightly better Fukuda stepping test performance. Given the small number of significant associations seen and their limited entities, this study does not support the existence of clinically relevant correlations for malocclusal traits and Helkimo Index ≥ 5 with body posture in children and young adults.

“…Perinetti (27) (2009), in an editorial on the study by Cuccia and Caradonna (28) , commented that although association between TMD and postural control has been observed in some studies, this does not mean that clinical relevance will follow. In fact, the importance of conducting controlled clinical research work must be emphasized in order to establish a real relationship between presence of TMD and posture.…”

“…The significance of the differences in each of the four posturographic variables between the two RP and ICP conditions was assessed by a paired Student’s t-test. To further assess the clinical significance of the differences in the four posturographic variables between the two RP and ICP conditions, an effects size (ES) coefficient24 was calculated. The ES coefficient is the ratio of the difference between the recordings of the two occlusal states divided by the within-subject standard deviation 25.…”

OBJECTIVES:Controversial results have been reported on potential correlations between the stomatognathic system and body posture. We investigated whether malocclusal traits correlate with body posture alterations in young subjects to determine possible clinical applications.METHODS:A total of 122 subjects, including 86 males and 36 females (age range of 10.8–16.3 years), were enrolled. All subjects tested negative for temporomandibular disorders or other conditions affecting the stomatognathic systems, except malocclusion. A dental occlusion assessment included phase of dentition, molar class, overjet, overbite, anterior and posterior crossbite, scissorbite, mandibular crowding and dental midline deviation. In addition, body posture was recorded through static posturography using a vertical force platform. Recordings were performed under two conditions, namely, i) mandibular rest position (RP) and ii) dental intercuspidal position (ICP). Posturographic parameters included the projected sway area and velocity and the antero-posterior and right-left load differences. Multiple regression models were run for both recording conditions to evaluate associations between each malocclusal trait and posturographic parameters.RESULTS:All of the posturographic parameters had large variability and were very similar between the two recording conditions. Moreover, a limited number of weakly significant correlations were observed, mainly for overbite and dentition phase, when using multivariate models.CONCLUSION:Our current findings, particularly with regard to the use of posturography as a diagnostic aid for subjects affected by dental malocclusion, do not support existence of clinically relevant correlations between malocclusal traits and body posture.
