Table 1: The Oral health Impact Profile scores (mean ±S.D) in relation with Index of Orthodontic Treatment Needs (Dental Health Component)-IOTN (DHC).Those with definitive need for treatment showed higher impacts on oral health in relation to functional limitation and physical pain, than those who had borderline need, little need, or no need for treatment. Nonetheless, this was not statistically significant.
