ABSTRACT
Early treatment of orthodontic problems is
important to ensure the best outcome and to avoid social stigmatization. Treatment
is often prioritized based on scales such as the index of Orthodontic Treatment
Need (IOTN).
Unfortunately, the conventional aesthetic component of IOTN measurement is
slanted towards Caucasian malocclusions. Thus, Asian children find it particularly
difficult to rate their appearance on this scale and therefore treatment may be
wrongly prioritized. This study aimed to assess the use of a newly modified
aesthetic scale in assessing orthodontic treatment need in adolescent. A total
of 522 16-year old children were recruited. The subjects as well as the
examiner rated the subject’s own dentition according to the conventional scale
of aesthetic component of IOTN and the newly modified aesthetic scale.
Questionnaire was given to assess the practicality of the two scales. When
conventional scale was used, subjects and examiner tends to rate more to the
no/slight treatment need category. However, when the newly modified scale was
applied, the rating has skewed to the moderate/great need treatment category in
both subjects and examiner. Moderate inter-agreement between examiner and
subjects were detected when using the modified scale while poor agreement was
found when using the conventional scale. Moreover, subjects found the modified
scale to be easier and faster to use and more relevant
to their own dentition. In conclusion, the newly modified aesthetic scale can
be suggested as a better tool in assessing level of orthodontic treatment need
in adolescent.

ABSTRAK
Menjalani rawatan awal untuk permasalahan
ortodontik adalah penting dalam memastikan hasil yang terbaik dan dapat
menghindari keaiban sosial. Keutamaan untuk mendapatkan rawatan selalunya
menggunakan skala seperti Indeks Keperluan Rawatan Ortodontik (IOTN)’. Malangnya, skala konvensional ini cendurung ke arah maloklusi
‘Caucasian’. Ini menyebabkan kanak kanak Asia sukar
untuk menilai penampilan mereka menggunakan skala ini dan keutamaan untuk
rawatan mungkin disalahtafsirkan. Penyelidikan ini
bertujuan untuk menguji kegunaan satu skala estetik baru yang diubah suai dalam
menilai keperluan rawatan ortodontik dalam kalangan remaja. Sejumlah 522 remaja berusia 16 tahun telah direkrut. Subjek dan pemeriksa telah menilai gigi subjek itu sendiri
berdasarkan skala estetik konvensional IOTN dan skala estetik baru yang diubah suai. Soalan kaji selidik juga telah diberikan untuk menilai
keberkesanan kedua jenis skala tersebut. Apabila skala
konvensional digunakan, subjek dan pemeriksa cenderung untuk menilai ke
kategori tidak/sedikit perlu untuk rawatan. Namun,
apabila skala baru digunakan, penilaian telah memencong ke kategori
sederhana/sangat memerlukan rawatan dalam kalangan subjek dan pemeriksa. Keserasian pendapat antara pemeriksa dan subjek adalah
sederhana apabila menggunakan skala yang diubah suai manakala ketidakserasian
pendapat berlaku apabila skala konvensional digunakan. Tambahan pula, subjek merasakan skala yang diubah suai itu lebih
senang dan cepat digunakan serta lebih berkait dengan kegigian mereka. Skala estetik baru yang diubah suai ini boleh dicadangkan sebagai
satu alat yang lebih baik dalam menilai tahap keperluan rawatan ortodontik
dalam kalangan remaja.
