- Sample size: 276; two-related-samples test: Wilcoxon Signed Ranks Test. OHRQoL were classified into quartiles; IOTN (DHC) and IOTN (AC): no need, borderline need, definite need; DAI: normal or minor malocclusion, definite malocclusion, severe malocclusion, very severe (handicapping) malocclusion; ICON: no, yes; ICON complexity: easy, mild, moderate, difficult, very difficult; PAR: almost ideal occlusion, acceptable occlusion, malocclusion
