Studies associated with deaf children's malocclusion and their treatment need are still very rare. Therefore, cephalometric analysis with the ability to access the skeletal, dental, and soft tissues can be used to score the severity of malocclusion and index of orthodontic treatment need (IOTN) in deaf children. This study examined the use of cephalometric analysis, severity malocclusion, and orthodontic treatment need in deaf students at special need school type B (SLB-B) in Surabaya using IOTN along with investigating IOTN correlation with the result of dental cephalometric analysis and dental health component (DHC) and aesthetic component (AC) in IOTN index.
Sample data consisted of 33 students between the ages of 8 to 12 years old and never had any orthodontic treatment. This investigation applied the indices from IOTN, in which DHC had 10 malocclusions, and AC with the aesthetic anterior dentition comprising 10 color photographs and different dental attractiveness levels. In addition, scores were chosen from the worst feature, with the data analyzed at a significant correlation test of 0.05%.
There was no skeletal abnormality in deaf children. It displayed the highest number of malocclusion severity scores, while the DHC assessment showed the moderate and severe categories. Based on AC evaluation, the highest numbers of malocclusion severity were found in good and moderate category in terms of teeth arrangement and aesthetic.
There was a correlation between the dental cephalometric analysis in deaf children and treatment need using IOTN with AC and DHC.
与聋儿错牙合畸形及其治疗需求相关的研究仍然非常罕见。因此，能够对骨骼、牙齿和软组织进行评估的头影测量分析可用于评估聋儿错牙合畸形的严重程度和正畸治疗需求指数（IOTN）。本研究使用IOTN对头影测量分析、错牙合畸形严重程度以及泗水B类特殊需求学校（SLB - B）的聋生正畸治疗需求进行了研究，并调查了IOTN与牙科头影测量分析结果以及IOTN指数中的牙齿健康成分（DHC）和美学成分（AC）之间的相关性。
样本数据包括33名年龄在8至12岁之间且从未接受过任何正畸治疗的学生。本调查应用了IOTN的指数，其中DHC有10种错牙合畸形，AC的美学前牙列包括10张彩色照片和不同的牙齿美观水平。此外，从最严重的特征中选取分数，并在0.05%的显著性相关检验下对数据进行分析。
聋儿无骨骼异常。错牙合畸形严重程度得分显示出最高数量，而DHC评估显示为中度和重度类别。基于AC评估，在牙齿排列和美观方面，错牙合畸形严重程度最高的数量出现在良好和中度类别中。
聋儿的牙科头影测量分析与使用IOTN的AC和DHC治疗需求之间存在相关性。
