Esthetically, malocclusion could affect a person’s appearances and psychological development especially in adolescent. Orthodontic treatment is performed to fix the malocclusion that could affect one’s oral health.

This study was aimed to obtain the needs of orthodontic treatment based on IOTN among students aged 12-13 years old at SMPN 1 Wori. This was an observational descriptive study with a cross sectional design. There were 30 respondents obtained by using purposive sampling technique.

The needs of orthodontic treatment measured with AC, 27 person (90%) were as follows: no need or little need for treatment in 27 students (90%); borderline need in 2 students (6.7%); and treatment required in 1 student (3.3%). The needs of orthodontic treatment based on DHC were as follows: no need or little need for treatment in 18 students (60%); borderline need in 8 students (26.7%); and treatment required in 4 students (13.3%).Keywords: malocclusion, needs of orthodontic treatment, IOTN. Abstrak: Maloklusi merupakan penyimpangan oklusi akibat tidak teraturnya pertumbuhan, posisi, serta ukuran gigi. Maloklusi dapat menyebabkan gangguan kesehatan fisik dan psikis, antara lain dapat mengganggu fungsi oral, mastikasi, berisiko tinggi terhadap trauma, penyakit periodontal, dan karies. Maloklusi secara estetis juga dapat memengaruhi penampilan wajah seseorang dan perkembangan psikologis terutama pada remaja. Perawatan ortodonsi ditujukan untuk memperbaiki maloklusi yang dapat memengaruhi kesehatan gigi dan rongga mulut. Perawatan ortodonsi yang tepat dapat dilihat dari tingkat kebutuhan perawatan ortodonsi yang diukur dengan Index of Orthodontic Treatment Need (IOTN). Penelitian ini bertujuan untuk mengetahui kebutuhan perawatan ortodonsi berdasarkan IOTN pada siswa berusia 12 - 13 tahun di SMP N 1 Wori. Jenis penelitian ialah deskriptif observasional dengan desain potong lintang. Subjek penelitian berjumlah 30 siswa diperoleh dengan teknik purposive sampling. Kebutuhan perawatan ortodonsi menggunakan Index of Orthodontic Treatment Need (IOTN) dengan dua komponen, yaitu Aesthetic Component (AC) dan Dental Health Component (DHC). Kebutuhan perawatan ortodonsi berdasarkan AC yaitu: 27 orang (90%) tidak atau butuh perawatan ringan; 2 orang (6,7%) perawatan borderline; dan 1 orang (3,3%) sangat butuh perawatan. Kebutuhan perawatan ortodonsi berdasarkan DHC yaitu: 18 orang (60%) tidak atau butuh perawatan ringan; 8 orang (26,7%) perawatan borderline, dan 4 orang (13,3%) sangat butuh perawatan.
