“…It is important that the indices have a high degree of reproducibility to be useful as a research tool. Despite the lower ICC DHC-IOTN as compared to the DAI value, the confidence intervals are coincident, showing that the reproducibility of both is similar [1,11,12,17,18]. …”

The present study assesses the validity and reproducibility of two occlusal indices for epidemiological studies—the Dental Aesthetic Index (DAI) and the Dental Health Component of the Index of Orthodontic Treatment Need (DHC-IOTN) for the identification of orthodontic treatment needs. The total of 131 study models was examined by an examiner (orthodontic specialist) for the determination of the DAI and DHC-IOTN. Thirty days later, further assessment was performed to determine the reproducibility. The duration of each exam was measured in seconds with a stopwatch. The indices were compared by a panel of three experts in orthodontics to evaluate validity. The intra-examiner reliability evaluation resulted in an intraclass correlation coefficient of 0.89 for the DAI (95% CI = 0.64 to 1.0) and 0.87 for the DHC-IOTN (95% CI = 0.56 to 0.96). The time spent on the evaluation of the DHC-IOTN was less than the time spent on that of the DAI (P < 0.001). The accuracy of the indices, as reflected by the area under the receiver-operating characteristic curve, was 61% for the DAI (95% CI = 51 to 70; p = 0.037) and 67% for the DHC-IOTN (95% CI = 58 to 77; p = 0.001). Both indices presented good reproducibility and validity.

“…The aesthetic component (AC) consists of a scale of 10 colored pictures showing different levels of beauty of the smiles and the objective of the scale is to find a similar occlusion or the level of equivalent severity to the individual appraised, placing the occlusion in relation to the number where “1” represents the most attractive occlusion and “10” represents the least attractive occlusion. An AC score below “5” indicates no need or only a slight need of orthodontic treatment; a score between 5 and 7 shows a borderline need; and a score between 8 and 10 shows a definite need [ 18 ]. Orthodontists matched the patients to these photographs.…”

Aim. This case-control retrospective study is aimed at assessing if obese adolescents need more orthodontic treatment in comparison with normal-weight patients of the same age. Methods. The test group included 100 obese subjects (50 males and 50 females; average age: 13.09 ± 1.19 years old) and the control group included 100 normal-weight patients matched for age and sex (50 males and 50 females; average age: 13.07 ± 1.26 years old). Clinical examinations were conducted on dental casts to assess the need of orthodontic treatment, by using the Index of Orthodontic Treatment Need (IOTN) (DHC, dental health component; AC, aesthetic components). Results. No statistically significant difference (P > 0.05) was observed between the two groups with regard to AC. Obese females showed a significant (P < 0.05) higher percentage of DHC 3 (32%) in comparison to the normal-weight girls (22%); for the other grades of DHC and for the single kind of malocclusion, no significant difference was found. Conclusions. Obese adolescents showed a similar need for orthodontic treatment compared to normal-weight patients of the same age. However, in obese females, a slightly greater need for orthodontic treatment was observed, compared to normal-weight patients.

“…It does not cover important features such as cross-bite, midline deviation, or overbite and may under-diagnose the need for orthodontic treatment [4,11]. It may underestimate the need for orthodontic treatment in cases where the canine is displaced, when the incisors are rotated or crowded, and cases of increased overbite; however, it may overestimate the need for orthodontic treatment when there is an increase in overjet, even in straight teeth [19]. Moreover DAI was integrated into the International Collaboration Study of Oral Health Outcomes by the World Health Organization [20] and has been used worldwide in epidemiologic studies of orthodontic treatment need in several industrialized and developing countries [3,10].…”

Objective: This study aimed to assess the prevalence of the orthodontic treatment need in Brazilian adolescents by using the Dental Aesthetic Index (DAI), investigate associations between DAI scores and demographic and socioeconomic variables, and identify the components of the DAI that primarily contribute to the severity of malocclusion. Methods: This cross-sectional study was conducted in the public schools of Balneário Camboriú, Brazil; the study sample comprised 704 adolescents aged 12-13 years without history of orthodontic treatment. Malocclusion was assessed by a trained and calibrated orthodontist using the DAI. Results: Of the schoolchildren, 58.7% had no malocclusion, 24.0% had definite malocclusion, 10.9% had severe malocclusion, and 6.4% had handicapping malocclusion. Approximately 17% of the sample (95% confidence interval: 14.5-20.1) required orthodontic treatment. Anterior maxillary overjet (r=0.627), anteroposterior molar relationship (r=0.590), irregularity in the maxilla (r=0.345), irregularity in the mandible (r=0.332), and crowding in the incisal segments (r=0.305) were the DAI components that primarily contributed to the variations in DAI scores. Conclusion: Almost one-fifth of the sample required orthodontic treatment. Maxillary overjet and molar relationship represent the characteristics that primarily influenced the need for orthodontic treatment in the study population.Prevalência da maloclusão e necessidade de tratamento ortodôntico entre alunos escolares brasileiros de 12 e 13 anos de idade Resumo Objetivo: O objetivo deste estudo foi o de avaliar a prevalência da necessidade de tratamento ortodôntico em adolescentes brasileiros, utilizando o Índice de Estética Dental (DAI), investigar as associações entre os escores DAI e variáveis demográficas e socioeconômicas, bem como identificar os componentes do DAI que contribuem principalmente para a gravidade da maloclusão. Métodos: Este estudo transversal foi realizado em escolas públicas de Balneário Camboriú, Brasil; a amostra foi constituída por 704 adolescentes com idades entre 12-13 anos, sem histórico de tratamento ortodôntico. A má oclusão foi avaliada por um ortodontista treinado e calibrado usando o DAI. Resultados: Das crianças em idade escolar, 58,7% não tinham má oclusão, 24,0% tinham má oclusão definida, 10,9% tinham má oclusão severa, e 6,4% tinham fragilizando má oclusão. Cerca de 17% da amostra (intervalo de confiança de 95%: 14,5-20,1) necessitaram de tratamento ortodôntico. Overjet maxilar (r=0,627), relação molar antero-posterior (r=0,590), irregularidade na maxila (r=0,345), irregularidade na mandíbula (r=0,332); apinhamento de incisivos (r=0,305) foram os componentes do DAI que contribuíram principalmente para as variações nos escores DAI. Conclusão: Quase um quinto da amostra necessitava de tratamento ortodôntico. Overjet maxilar e relação molar representaram as características que influenciaram principalmente a necessidade de tratamento ortodôntico na população do estudo.Palavras-chave: Epidemiologia; Maloclusão; Ortod...
