Malocclusion and orthodontic treatment need of secondary school students in Nigeria according to the dental aesthetic index (DAI).

The aims of this study were to measure the distribution, prevalence and the severity of malocclusion and treatment need amongst randomly selected (n = 703) rural and urban Nigerian children aged 12-18 years (mean 14.0 +/- 1.84) using the dental aesthetic index (DAI), and to assess whether malocclusion was affected by age, gender and socio-economic background.

Perceptions of dental aesthetics in the United States and Nigeria.

The standard dental aesthetic index (DAI) is an orthodontic treatment need index based on perceptions of dental aesthetics in the United States. It is a regression equation that links perceptions of the social acceptability of dental aesthetics with the objective intraoral measurements of ten occlusal traits. For the index to be universally acceptable, the perceptions of dental aesthetics in other countries must be similar to those of the United States.

A comparison of DAI scores and characteristics of occlusal traits in three ethnic groups of Asian origin.

The Dental Aesthetic Index (DAI) is an orthodontic index based on socially defined aesthetic standards. The primary aim of this study was to compare the prevalence of malocclusion using the DAI among three ethnic groups of Asian origin; Japanese, Chinese in Taiwan and Native Americans with white Americans. A secondary goal was to consider the possibility that genetic factors might be the cause of the characteristics of malocclusion in the ethnic groups of Asian origin.

Comparing and contrasting two orthodontic indices, the Index of Orthodontic Treatment need and the Dental Aesthetic Index.

This article compares and contrasts two orthodontic indices, the Index of Orthodontic Treatment Need (IOTN), and the Dental Aesthetic Index (DAI). Both contain esthetic and clinical criteria. Both accept the premise that a significant benefit of orthodontic treatment is improved esthetics and, by inference, social and psychological well-being.

Establishing malocclusion severity levels on the Dental Aesthetic Index (DAI) scale.

The Dental Aesthetic Index (DAI) is an orthodontic index based on socially defined aesthetic standards. It is useful in both epidemiological surveys to identify unmet need for orthodontic treatment and as a screening device to determine priority for subsidized orthodontic treatment. An earlier study established the score of 36 on the DAI scale to identify handicapping malocclusions.
