Abstract
The aims of this study were to evaluate self-perceived orthodontic treatment needs on the aesthetics of tooth alignment, self-perceptions to the appearance of teeth, and the association of both. Five hundred eighty-eight schoolchildren aged 12 to 14 years were selected to answer the questionnaires, which consisted of forms relating to self-perceived orthodontic treatment need using the Aesthetic component of the Index of orthodontic treatment need (IOTN-AC), and perceptions on dental aesthetic using an Oral Aesthetic Subjective Impact Scale (OASIS). The final score of OASIS added IOTN-AC (OASIS_AC) was interpreted into self-perception. The mean IOTN-AC grade was 2.33 (SD = 1.28). Most participants (n = 564, 95.9 percent) had low IOTN-AC grade reflecting no or slight orthodontic treatment need. The mean OASIS score of all students was 12.67 (SD = 5.42). In three hundred thirty-eight of the students (57.5 percent) had high OASIS score reflecting moderate or high demand in orthodontic treatment. The correlation test between IOTN-AC and OASIS score was slightly (r = 0.344). The majority (n = 291, 49.5 percent) of participants had low OASIS_AC score reflecting positive self-perception towards the appearance of their teeth. Gender had influence (P<0.001) only in the IOTN-AC grade. In conclusion, dissatisfaction with dental appearance has found to be associated with the desire for orthodontic treatment, and participants with negative self-perceptions have found to be more likely to undergo orthodontic treatment. However, most participants still concerned about the appearance of their teeth (high OASIS score) even though they thought that no treatment was needed (low IOTN-AC grade), leading to unnecessary orthodontic treatment.
