To determine the orthodontic treatment needs of patients attending a Nigerian Teaching Hospital using the Dental Aesthetic Index.
One hundred and fifty study models of patients who attended the Orthodontic clinic of the Lagos University Teaching Hospital were assessed using the DAI. The data was collected using an evaluation form. Descriptive statistics, Chi-square values and t-tests were used to analyze the data.
The mean DAI score was 31.5 ± 9.7. Overall, 32% of the subjects had no need or slight need for orthodontic treatment. In 23.3% the need for treatment was elective. Severe malocclusion with treatment highly desirable was found in 16.7% and 28% had handicapping malocclusion with treatment considered mandatory. There were no significant gender differences with regard to the DAI treatment categories (p > 0.05). There were no statistically significant differences in mean DAI scores between age groups, gender and social class (p > 0.05).
This study showed that close to one-third of the subjects had dental appearance that did not require treatment. A significant proportion (28%) of the subjects had very severe (handicapping) malocclusion and could qualify for publicly subsidized orthodontic treatment.
使用牙科美学指数确定在一家尼日利亚教学医院就诊的患者的正畸治疗需求。
使用牙科美学指数（DAI）对拉各斯大学教学医院正畸门诊的150名患者的研究模型进行评估。通过评估表收集数据。使用描述性统计、卡方值和t检验对数据进行分析。
平均DAI评分为31.5±9.7。总体而言，32%的受试者不需要或仅轻微需要正畸治疗。23.3%的患者治疗需求为选择性的。16.7%的患者存在严重错牙合畸形且强烈需要治疗，28%的患者存在妨碍性错牙合畸形且治疗被认为是必需的。在DAI治疗类别方面，性别差异无统计学意义（p>0.05）。年龄组、性别和社会阶层之间的平均DAI评分无统计学显著差异（p>0.05）。
本研究表明，近三分之一的受试者牙齿外观无需治疗。相当比例（28%）的受试者存在非常严重（妨碍性）的错牙合畸形，有资格获得公共补贴的正畸治疗。
