Abstract

Purpose: Generating adequate tongue pressure against the hard palate requires full-range mobility of the tongue. The study aimed to (1) determine the prevalence of restricted tongue mobility and ankyloglossia and (2) determine whether, in children with restricted tongue mobility, their condition also affects tongue pressure.

Methods: A cross-sectional study of healthy 6-8-year-old children from primary schools in central Vietnam was conducted in 2019. Restricted tongue mobility and ankyloglossia were graded using the tongue range of motion ratio (TRMR), with the tongue-tip-to-incisive papillae (TIP) for the anterior tongue tip and lingual-palatal suction (LPS) for the posterior two-thirds of the tongue. Tongue strength and tongue endurance were measured by the Iowa Oral Pressure Instrument. Statistical analysis investigated the associations between tongue mobility and tongue pressure measurement.

Results: Five hundred twelve children (46.5% female, mean age 7.2 ± 0.2 years) were assessed. The prevalence of anterior ankyloglossia and restricted mobility was 17.5%, with 16.2% cases of less than 50% mobility and 1.3% cases of less than 25% mobility. The prevalence of posterior ankyloglossia and restricted mobility with less than 30% mobility was 28.9%. Anterior restricted mobility was not a predictor of reduced tongue pressure. Posterior restricted mobility in LPS was independently associated with tongue strength but not tongue endurance.

Conclusion: Restrictions of posterior tongue mobility in ankyloglossia are more frequent than restrictions in anterior tongue mobility. Reduced tongue strength is related to mobility and the severity of restrictions in the posterior tongue. These findings suggest that restricted posterior tongue mobility may affect tongue muscle weakness.

6-8 岁越南学龄儿童舌头活动受限和踝舌症:发病率及其与舌头力量和耐力的关系。
目的:要使舌头对硬腭产生足够的压力,需要舌头具有全方位的活动能力。本研究旨在:(1)确定舌头活动受限和踝舌症的发病率;(2)确定舌头活动受限的儿童的情况是否也会影响舌压:方法:2019 年对越南中部小学 6-8 岁的健康儿童进行了一项横断面研究。采用舌运动范围比(TRMR)对舌活动受限和踝舌进行分级,舌尖-incisive乳头(TIP)代表舌前部,舌-腭吸力(LPS)代表舌后部的三分之二。舌头力量和舌头耐力由爱荷华州口腔压力测试仪测量。统计分析研究了舌头活动度与舌压测量之间的关联:共评估了 512 名儿童(46.5% 为女性,平均年龄为 7.2 ± 0.2 岁)。前方强直性舌炎和活动受限的发病率为 17.5%,其中 16.2% 的患儿活动度低于 50%,1.3% 的患儿活动度低于 25%。后方踝舌炎和活动受限的发病率为28.9%,其中活动度低于30%的占16.2%,低于25%的占1.3%。前方活动受限并不是舌压降低的预测因素。LPS的后方活动度受限与舌强度有独立关联,但与舌耐力无关:结论:强直性舌后位活动受限比舌前位活动受限更为常见。舌强度的降低与舌后活动度和限制的严重程度有关。这些发现表明,舌后活动受限可能会影响舌肌无力。

期刊介绍: The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
