Abstract
Objectives 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) Tunarungu Karya Mulia 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. Material and Methods 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%. Result 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. Conclusion There was a correlation between the dental cephalometric analysis in deaf children and treatment need using IOTN with AC and DHC.
Highlights
Orthodontics refers to the supervision, guidance, and correction of both developing and developed dentofacial structures.[1]

Based on the results from the research conducted at SLB-B Tunarungu Karya Mulia students in Surabaya, using cephalometric analysis, no abnormality was detected in the skeletal system of deaf children
Summary
Orthodontics refers to the supervision, guidance, and correction of both developing and developed dentofacial structures.[1]. Its prevalence varies according to the geographical base, population, ethnicity, age, sex, and urbanization, and it can be overcome by utilizing secure procedures that are applicable to the type that requires orthognathic surgery.[3] It is usually diagnosed in patients with typical health conditions such as cleft lip and palate, Down’s syndrome, as well as other diseases; it emerges due to the direct outcome of a disorder or associated ailment.[4] it is detected in children with a hearing impairment, leading to the communication problems that affect certain aspects of their growth, development, and ability.[5] Speech disorder is a type of condition or communicative behavior characterized by difficulty in the production of speech sounds This occurs due to certain abnormalities in the shape and structure of the speech organs, which consist of politicizes, malocclusions, anomalies, deviations, or congenital defects such as the thick tongue or minimal growth of frenulum.[6]
