ABSTRACT Objective: To investigate the aesthetic perceptions of 100 consecutive patients and their
parents of orthodontic treatment need and to compare their observations with that of
orthodontists.
Methods: The sample consisted of 100 consecutive orthodontic patients seen for the first
time at a Nigerian Hospital. Of the total sample, 49 were males and 51 were females,
with ages ranging from 7 to 21 years (mean + SD; 12.81 + 3.08). The self-assessment by
patients and the recording by parents and orthodontists were carried out using the
Aesthetic (AC) and Dental Health (DHC) Components of Index of Orthodontic
Treatment Need (IOTN) as applicable.
Results: The results showed a strong association in the perception of dental appearance
by patients and the views of other dental assessors. These correlations were highly
statistically significant (P<0.001) with the highest correlation between the parents and the
orthodontists (r =0.791) while the least was between the patients and the orthodontists (r
= 0.653). The study also found that about one-half of the patients were in the "definite
need for orthodontic treatment".
Conclusions: There is a strong relationship in the perceptions of dental appearance by
patients, parents and orthodontists. This index could therefore be used as an effective tool
in communication and achieving realistic treatment decisions.
Keywords: Orthodontic perception, Index of Orthodontic Treatment Need (IOTN),
patients, parents, orthodontists.
