There is a strong correlation between malocclusion status and DHC-IOTN (r=0.65, p>0.05), malocclusion and AC-IOTN have an average correlation (r=0.44, p>0.05). There is also a strong correlation between AC-IOTN and DHC-IOTN (r=0.60, p>0.05). There was no gender difference between treatment levels for dental health and dental aesthetics with p>0.05.
