■该研究旨在评估牙齿错牙合的患病率,正畸参数,发育性阅读障碍(DD)儿童的功能习惯。
■40名儿科患者(67.5%的男孩和32.5%的女孩,平均年龄:11.02±2.53岁,范围:6-15岁)将DD与40名年龄和性别匹配的健康参与者进行牙齿错牙合的患病率比较,正畸参数,和超功能习惯。牙科检查由正畸医生进行。
■患有DD的儿科患者的AngleIII类错牙合的患病率明显更高(22.5%vs.5.0%,P=0.024),深咬伤(27.5%vs.7.5%,P=0.019),中线偏差(55.0%与7.5%,P<0.0001),中线舒张(32.5%与7.5%,P=0.010),磨损方面(92.5%与15.0%,P<0.0001),自我报告夜间磨牙(82.5%vs.7.5%,P<0.0001),咬指甲(35.0%vs.0.0%,P<0.0001),和非典型吞咽(85.0%vs.17.5%,P<0.0001)与健康对照组相比。
■患有DD的儿科患者表现出较高的III类错牙合患病率,较大的正畸垂直和横向差异,和功能异常活动的发生率。临床医生和牙医应意识到阅读障碍儿童表现出错牙合的脆弱性,并鼓励早期评估和多学科干预。
UNASSIGNED: The study aimed to assess the prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits in children with developmental dyslexia (DD).
UNASSIGNED: Forty pediatric patients (67.5% boys and 32.5% girls, mean age: 11.02 ± 2.53 years, range: 6-15 years) with DD were compared with 40 age- and sex-matched healthy participants for prevalence of dental malocclusion, orthodontic parameters, and parafunctional habits. Dental examinations were performed by an orthodontist.
UNASSIGNED: Pediatric patients with DD exhibited a significantly higher prevalence of Angle Class III malocclusion (22.5% vs. 5.0%, P = 0.024), deep bite (27.5% vs. 7.5%, P = 0.019), midline deviation (55.0% vs. 7.5%, P < 0.0001), midline diastemas (32.5% vs. 7.5%, P = 0.010), wear facets (92.5% vs. 15.0%, P < 0.0001), self-reported nocturnal teeth grinding (82.5% vs. 7.5%, P < 0.0001), nail biting (35.0% vs. 0.0%, P < 0.0001), and atypical swallowing (85.0% vs. 17.5%, P < 0.0001) compared to that in healthy controls.
UNASSIGNED: Pediatric patients with DD showed a higher prevalence of Class III malocclusion, greater orthodontic vertical and transverse discrepancies, and incidence of parafunctional activities. Clinicians and dentists should be aware of the vulnerability of children with dyslexia for exhibiting malocclusion and encourage early assessment and multidisciplinary intervention.
