Disertasi ini merupakan hasil penelitian eksploratif kualitatif dan kuantitatif. Indikator yang dapat menilai kebutuhan perawatan ortodonti interseptif yaitu: frenulum, karies molar kedua sulung, kehilangan gigi anterior, peg shape, kehilangan dini molar pertama dan kedua sulung rahang bawah, pergerakan ke mesial molar pertama bawah, persistensi gigi anterior sulung, kehilangan dini kaninus sulung, gigitan silang anterior, gigi berjejal insisivus permanen, hubungan molar, diastema, jarak gigit, gigitan dalam, gigi supernumerary, gigitan terbuka anterior dan gigitan silang posterior. Pendidikan orang tua signifikan berpengaruh terhadap kebutuhan perawatan ortodonti interseptif. Pendapatan, pengetahuan, sikap orang tua dan umur, jenis kelamin serta tindakan anak signifikan tidak mempengaruhi kebutuhan perawatan ortodonti interseptif. Indeks Kebutuhan Perawatan Ortodonti Interseptif memiliki kesesuaian dengan Index of Orthodontic Treatment Need (IOTN) sebagai indeks pembanding.
