OBJECTIVES
To characterize associations between restricted tongue mobility and maxillofacial development.
SETTING AND SAMPLE POPULATION
Cross-sectional cohort study of 302 consecutive subjects from an orthodontic practice.
MATERIAL AND METHODS
Tongue mobility (measured with tongue range of motion ratio [TRMR] and Kotlow free tongue measurement) was correlated with measurements of the maxillofacial skeleton obtained from dental casts and cephalometric radiographs.
RESULTS
Tongue range of motion ratio and Kotlow measures of restricted tongue mobility were associated with (i) ratio of maxillary intercanine width to canine arch length, (ii) ratio of maxillary intermolar width to canine arch length and (iii) soft palate length. Restricted tongue mobility was not associated with hyoid bone position or Angle's skeletal classification.
CONCLUSIONS
Restricted tongue mobility was associated with narrowing of the maxillary arch and elongation of the soft palate in this study. These findings suggest that variations in tongue mobility may affect maxillofacial development.
目的
描述舌活动受限与颌面部发育之间的关系。
设置和样本人群
这是一项来自正畸诊所的 302 例连续患者的横断面队列研究。
材料和方法
使用舌活动范围比（TRMR）和 Kotlow 自由舌测量来测量舌活动度，并将其与从牙模和头颅侧位片获得的颌面部骨骼测量值相关联。
结果
舌活动范围比和 Kotlow 测量的舌活动受限与以下指标相关：（i）上颌尖牙间宽度与尖牙弓长的比值，（ii）上颌磨牙间宽度与尖牙弓长的比值，（iii）软腭长度。舌活动受限与舌骨位置或安氏骨骼分类无关。
结论
在这项研究中，舌活动受限与上颌弓狭窄和软腭伸长有关。这些发现表明，舌活动度的变化可能会影响颌面部发育。
