The objectives of this study were to investigate the occurrence, types and severity of malocclusions in children with speech sound disorder (SSD) persisting after 6 years of age, and to compare these findings to a control group of children with typical speech development (TSD).
In total, 105 children were included: 61 with SSD and motor speech involvement (mean age 8:5 ± 2:8 years; range 6:0-16:7 years, 14 girls and 47 boys) and 44 children with TSD (mean age 8:8 ± 1:6; range 6:0-12:2 years, 19 girls and 25 boys). Extra-oral and intra-oral examinations were performed by an orthodontist. The severity of malocclusion was scored using the IOTN-DHC Index.
There were differences between the SSD and TSD groups with regard to the prevalence, type, and severity of malocclusions; 61% of the children in the SSD group had a malocclusion, as compared to 29% in the TSD group. In addition, the malocclusions in the SSD group were rated as more severe. Functional posterior crossbite and habitual lateral and/or anterior shift appeared more frequently in the SSD group. Class III malocclusion, anterior open bite and scissors bite were found only in the SSD group.
Children with SSD and motor speech involvement are more likely to have a higher prevalence of and more severe malocclusions than children with TSD.
本研究旨在调查 6 岁以上持续性言语障碍（SSD）儿童的错畸形发生、类型和严重程度，并与具有典型言语发育（TSD）的对照组儿童进行比较。
共纳入 105 名儿童：61 名 SSD 合并运动性言语障碍儿童（平均年龄 8.5 ± 2.8 岁；范围 6.0-16.7 岁，14 名女孩和 47 名男孩）和 44 名 TSD 儿童（平均年龄 8.8 ± 1.6 岁；范围 6.0-12.2 岁，19 名女孩和 25 名男孩）。正畸医生进行了口外和口内检查。使用 IOTN-DHC 指数对错畸形的严重程度进行评分。
SSD 和 TSD 组在错畸形的发生率、类型和严重程度方面存在差异；SSD 组中 61%的儿童存在错畸形，而 TSD 组中这一比例为 29%。此外，SSD 组的错畸形程度更严重。功能性后牙反颌、习惯性侧向和/或前牙移位在 SSD 组中更为常见。III 类错畸形、前牙开颌和剪刀型咬合仅在 SSD 组中发现。
与 TSD 儿童相比，合并运动性言语障碍的 SSD 儿童更有可能出现更高的错畸形发生率和更严重的错畸形。
