The relationship between dental aesthetic index (DAI) and perceptions of aesthetics, function and speech amongst secondary school children in Ibadan, Nigeria

Abstract

The study has shown weak but significant correlation between DAI and children's perceptions of the appearance of their teeth. We recommend further study involving both DAI and Index of Orthodontic Treatment Need (IOTN) for comparison in the Nigerian population.

Relationship of the Dental Aesthetic Index to the oral health-related quality of life

“…Females scored higher means in four out of seven domains (domain 4, psychological discomfort; domain 4, physical disability; domain 5, psychological disability; domain 6, social disability; domain 7, handicap) along with the total score. Generally, the younger age group (12-19 years) scored higher means than did the older age group (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) in five out of seven (domain 3, psychological discomfort; domain 4, physical disability; domain 5, psychological disability; domain 6, social disability; domain 7 handicap) as well as the total score. Table 3 shows the Spearman rank-order correlation coefficients between the DAI and OHIP-14 scores, which showed significant but almost no correlation (r 5 .176) between the two instruments at all grades of the DAI summative score.…”

“…9,12,16,17,[20][21][22][23][24] A study in Malaysia utilized IOTN as the instrument. 20 Most of these studies have focused on a specific group such as children, orthodontic patients, or patients seeking orthodontic care.…”

“…20 Most of these studies have focused on a specific group such as children, orthodontic patients, or patients seeking orthodontic care. 9,12,16,17,[20][21][22][23][24] The current study used DAI as the instrument and covered a wider age range of population that comes for primary dental care, not specifically seeking orthodontic treatment.…”

“…This was also observed in another study, wherein quality of life was related to emotional rather than functional or social well-being. 23 The generic questionnaire does not directly assess malocclusion, 12 which is an asymptomatic deviation from the aesthetic norm rather than an acute disease. 12,30 Therefore, the sensitivity of OHIP-14 to changes in malocclusion is lower compared with other oral conditions.…”

Psychosocial Impact of Dental Esthetics on Quality of Life in Adolescents

“…Treatment is often justified by the potential enhancement of social and psychological well-being through improvements in appearance. 16,17 Traditional occlusal indices such as the Dental Aesthetic Index (DAI) and Index of Orthodontic Treatment Need (IOTN) evaluate the esthetic and anatomic components of malocclusion, 18 but they do not give any information about how malocclusion affects a patient's self-image and quality of life in terms of subjective well-being and daily functioning. 19 Recently there has been increasing interest in the incorporation of psychometric instruments that measure oral health-related quality-of-life (OHRQOL) outcomes 16,19,20 and assess body image perception 20,21 during the orthodontic treatment planning process.…”
