Orthodontic treatment need for Brazilian schoolchildren: a study using the Dental Aesthetic Index

Abstract: There is a high prevalence (65.6%) of malocclusion requiring orthodontic treatment in 12-year-old Brazilian schoolchildren. The most prevalent malocclusions in the study were: Crowding, Class II molar relationship and increased overjet. There was no significant correlation between the Index of Orthodontic Treatment Need - Aesthetic Component (IOTN-AC) related to dental aesthetic perception and the normative treatment need assessed with the DAI.

“…This result may be justified by the fact that crowding is the most prevalent malocclusion and, therefore, the one most associated with malocclusion by laypersons. 19 When the men were asked which of the malocclusions would motivate them to try and convince their companions to initiate treatment, they listed diastema and little tooth exposure. The gingival smile had no impact.…”

“…This type of malocclusion, especially when upper incisors are protruded, is likely to produce several consequences. Among these complications, for instance, there are significant esthetic [5] and social [6] impact on children, as well as on their dental health [7]; or it might even predispose them to upper front teeth trauma [8,9], or to upper airway complications, in severe cases [10].…”
