吐舌习惯是在吞咽时舌头与臼齿前面的牙齿接触的一种情况。舌头不正常的位置可能导致牙齿和骨骼的异常。本研究的目的是研究和比较有和没有伸舌习惯的儿童的软组织、牙齿和骨骼形态特征。本研究选取了21名10 ~ 14岁有伸舌习惯的儿童和21名无伸舌习惯的儿童作为研究对象。测量各项软、牙、头测量参数并进行统计学比较。值得注意的是，与没有舌突的儿童相比，更多的有舌突的儿童表现为嘴唇不能力（86%对14%），口腔呼吸习惯（38%对无），精神肌活动过度活跃（24%对无），开咬（52%对无）和口齿不清（86%对无）。舌突患儿上唇厚度增加，上颌门牙前倾，下颚门牙成角、前磨牙间、磨牙间宽度及所有骨骼参数均无差异。舌突似乎影响了一些软组织和牙齿特征，导致唇部功能不全、口腔呼吸习惯、颏肌活动过度活跃、口齿不清、开咬和上颌门牙前倾；然而，没有观察到明显的骨骼变化。
Tongue thrusting habit is a condition in which the tongue makes contact with any teeth anterior to the molars during swallowing. Abnormal positioning of tongue may result in dental and skeletal abnormalities. The aim of the present study was to study and compare soft-tissue, dental, and skeletal morphologic characteristics in children with and without tongue thrusting habit. A total of 21 children with tongue thrusting habit and 21 children without any habit between age 10 and 14 years were selected for the study. Various soft-issue, dental and cephalometric parameters were measured and compared statistically. Significantly, higher number of children with tongue thrusting showed lip incompetency (86% vs. 14%), mouth-breathing habit (38% vs. none), hyperactive mentalis muscle activity (24% vs. none), Open-bite (52% vs. none) and lisping (86% vs. none) when compared to children without tongue thrust. Children with tongue thrust showed increased upper lip thickness and proclination of maxillary incisors No differences were found in angulation of mandibular incisors, inter-premolar or inter-molar widths and all the skeletal parameters studied. Tongue thrust seemed to affect some of the soft-tissue and dental characteristics causing lip incompetency, mouth-breathing habit, and hyperactive mentalis muscle activity, lisping, open-bite, and proclination of maxillary incisors; however, no significant skeletal changes were observed.
