| Summary: | <span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>Muscular hypotonia is one of the clinical signs in patients with Down syndrome. As a characteristic of patients with Down syndrome, </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>hypotonia is clearly evident in face expression and oral dysfunction. Dentocraniofacial growth abnormalities in patients with Down </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>syndrome may be influenced by genetic and environmental factors. Stomatognathic system musculature as an environmental factor </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>(factor outside the bone) can affect dentocraniofacial growth by orofacial muscles activities when chewing, swallowing, breathing, and </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>speaking. Oral dysfunctions commonly seen in patients with Down syndrome are open mouth, protruding tongue posture, difficulties </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>when chewing, swallowing, and speaking, drooling, and mouth breathing. The purpose of this study was to observe how the mastication </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>muscular tone affecting the facial size of Down syndrome patient. Twenty five of 14-18 years old children with Down syndrome were </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>diagnosed by clinical characteristic and cytogenetic examination. Mastication muscular tone was described by masseter and temporalis </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>muscle synergy and oral function, whereas the facial size consisted of facial size of lateral, anteroposterior and vertical growth. The </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>result of regression test revealed that the degree of mastication muscular tone has a significant effect on facial size of the anteroposterior </em><span style="font-family: Tribune-Italic; font-size: 9pt; color: #231f20; font-style: normal; font-variant: normal;"><em>growth and facial size of vertical growth, but did not significantly influence the facial size of lateral growth.</em></span></span></span></span></span></span></span></span></span></span></span> |
