“…Several authors agree that the IOTN-DHC measures the severity of malocclusion,21 but the reliability of the IOTN-AC has been questioned 22,23. Indeed, many studies have shown that results differ considerably according to whether the treatment need is measured objectively with the IOTN-DHC or subjectively with the IOTN-AC 22,24,25.…”

ObjectiveTo evaluate the psychosocial impact of malocclusion, determine its relationship with the severity of malocclusion, and assess the influence of gender and social class on this relationship in adolescents.MethodsA random sample of 627 Spanish adolescents aged 12 - 15 years underwent intraoral examinations by 3 calibrated examiners (intraexaminer and interexaminer kappa > 0.85) at their schools. Psychosocial impact was measured through a self-rated Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The severity of malocclusion was measured by the Index of Orthodontic Treatment Need (IOTN). Gender and social class were also recorded.ResultsThe total PIDAQ score and those of its 4 subscales, social impact, psychological impact, aesthetic concern, and dental self-confidence, presented significant differences (p ≤ 0.05 by analysis of variance) and linear relationships with the IOTN grades (p ≤ 0.05 by linear regression). Stepwise linear regression models showed that the IOTN dental health component was a predictive variable of the total and subscale PIDAQ scores. Neither gender nor social class was an independent predictive variable of this relationship, except the linear model for psychological impact, where gender was a predictive variable. The occlusal conditions responsible for higher PIDAQ scores were increased overjet, impeded eruption, tooth displacement, and increased overbite.ConclusionsMalocclusion has a psychological impact in adolescents and this impact increases with the severity of malocclusion. Social class may not influence this association, but the psychological impact seems to be greater among girls.

“…One possible explanation is that the adolescent population has always been particularly concerned with appearance and aesthetics, sometimes not in a mature or objective way, and this could influence the results (16,17). On occasion, the patient’s perception of his or her malocclusion is not related to standard treatment need as determined objectively by the indices (16,18,19). Moreover, patients’ perceptions of malocclusion are usually quite different from those of the specialist (18,20).…”

Objectives: The purpose of this study was to assess the validity and reliability of the Spanish version of PIDAQ for application in adolescents. Study Design: The questionnaire was translated, cross-culturally adapted and completed by 627 adolescents (366 12-year-olds and 261 15-year-olds). The adolescents were also examined by 4 examiners who had been calibrated against a gold standard and relative to each other (Kappa >0.85) in determining treatment need with the Dental Aesthetic Index (DAI) and the Index of Orthodontic Treatment Need (IOTN) DHC and AC components. Results: Cronbach´s alpha of the translated PIDAQ was 0.90. The 23 items of the questionnaire were divided into four domains that explained 60% of the variance. The test-retest reliability of the questionnaire was 0.93. Discriminant validity revealed a significant association between the scores for the questionnaire and its subscales or domains and those for the DAI, IOTN-DHC and IOTN-AC treatment need indices. Adolescents with orthodontic treatment need scored higher in the questionnaires. Conclusions: The results show that the Spanish version of PIDAQ has a very similar internal structure and psychometric properties to those of the original questionnaire and demonstrate its validity for use with Spanish adolescents. Key words:Orthodontics, epidemiology, quality of life, malocclusion.

“…Similarly, some researches from other countries suggested that treatment need differs between gender and added that gender differences were presented for the AC of IOTN. 10,11,14,16,29 The orthodontic treatment need for the population in 1 specific region of Turkey was examined in several research studies (Table 5). 19,20,21,22,28 The first investigation on this topic was performed by Gü ray et al 19 for the Central Anatolia region of Turkey.…”

“…Therefore, occlusal indices such as Handicapping Labiolingual Deviation Index, 1 Treatment Priority Index, 2,3 Occlusal Index, 4,5 and the Standardized Continuum of Aesthetic Need Index 6 have been developed to assess the orthodontic treatment need in the last decade. The Index of Orthodontic Treatment Need (IOTN), defined by Brook and Shaw 7 and modified in 1995 8 classifies malocclusions in terms of occlusal features of dental health and perceived esthetic impairment and has been used in orthodontic investigations in many countries worldwide such as Italy, 9,10 France, 11 Sweden, 12 UK, 13,14 Saudi Arabia, 15 Spain, 16 Caribbean Islands, 17 and Finland.…”

Objective: The aim of this study was to identify the need for orthodontic treatment in Turkey and the differences between the 7 geographic regions. Materials and Methods: In the orthodontic part of the survey, extraoral and intraoral examination of 1023 randomly selected individuals (500 female and 523 male, mean ages 13.1063.11 years) was performed. The need of orthodontic treatment was evaluated with the aesthetic component (AC) and dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN). To analyze the data, descriptive statistical methods (mean value, prevalence ratio, and standard deviation) were performed. The significance of regional IOTN differences and gender distributions were assessed by means of chi-square test. Results: No statistically significant differences were found in gender distribution in the total and different regional samples (p.0.05). According to the DHC, 28.7% did not need orthodontic treatment, 16.3% were borderline cases, and 55.0% had severe need for orthodontic therapy. Little or no need for treatment was found in 91
