Abstract
Objective: The aim of this study was to determine the prevalence of malocclusion and orthodontic
treatment need in 13–18‑year‑old schoolchildren of Nalagarh, Himachal Pradesh, India using
the Index of Orthodontic Treatment need (IOTN) and to analyze the treatment needs between
males and females and correlation between the esthetic component (AC) and dental health
component (DHC) of IOTN.
Subjects and Methods: The sample comprised 2000 school children (1125 females and 875 males)
who had not undergone orthodontic treatment. No radiographs, study casts, were used; IOTN
was calculated from clinical examination.
Results: DHC results showed that little need for orthodontic treatment was found in 31.6%
and moderate need in 30.85%. A great need was estimated at 37.55%. Severe contact point
displacement of more than 4 mm was the most common occlusal feature in the definite treatment
need group, followed by increased overjet, impeded eruption of teeth, and anterior or posterior
cross bite. AC results showed that little need for orthodontic treatment was in 86.15%, moderate
need in 8.90%, and great need in 4.95%.
Limitations: Index does not consider midline discrepancy, soft tissue abnormalities, and AC
does not include Class III and Class II div 2 malocclusion photographs.
Conclusions: There seems a discrepancy in the proportion of children needing orthodontic
treatment on esthetic and dental health grounds. This study provides baseline data on the need
and demand for orthodontic treatment among the sample which is important for planning public
orthodontic and dental services.
