relationship between patient, parent and clinician perceived need
normative orthodontic treatment need
European Journal of Orthodontics. 26(3):265-71, 2004 Jun.
The aim of the present study was to compare patient, parent and
clinician perceived need for orthodontic treatment in relation
to normative orthodontic treatment need as measured by the Index
of Orthodontic Treatment Need (IOTN). A prospective
cross-sectional study was designed to address this aim. The
sample comprised 103 patients attending the 'new' patient clinic
at the Jordan University Hospital. The patients'
mean age was 15.3 years (standard deviation 3.8 years); 33 per
cent were males and 67 per cent females. One clinician scored
the patients' normative orthodontic treatment need using the
IOTN, then determined perceived need using a 10 cm visual
analogue scale (VAS). The subjects then assessed their own
perceived need and aesthetic component (AC) score and the
parents carried out similar assessments for their children. All
scoring was carried out blind. The parents had the highest
average perceived need scores, followed by patient and clinician
scores (6.6, 6.1 and 5.4 cm, respectively). A significant
difference was found between the parents and the clinician (P <
0.05). When the relationship between perceived need and
clinician-measured normative orthodontic treatment need was
investigated, significant differences were found with the dental
health component (DHC) for all three groups (P < 0.05).
Differences between AC and perceived need scores were also
significant for the patients and parents, but not for the
clinician (P > 0.05). The present study has shown that
perceptions of orthodontic treatment need are multifactorial and
influenced by elements other than health measures of normative
orthodontic treatment need and perceptions of aesthetics.
