There are few reports of the socio-demographic and malocclusion characteristics of those undergoing clinical orthodontic treatment in private specialist practice.
To describe the pretreatment characteristics of individuals presenting for orthodontic treatment.
Individuals (N = 174) presenting for orthodontic treatment in 19 private specialist orthodontic practices in New Zealand were randomly selected and examined (at the beginning of a three-year prospective study) and their malocclusions compared using the Dental Aesthetic Index (DAI).
The mean DAI score was 35.8 (SD 8.4). There were no statistically significant socio-demographic differences in DAI score other than by household-based socio-economic status (SES), whereby mean scores were considerably higher in those of low SES. The majority of patients attending for treatment had severe or very severe/handicapping malocclusions. Females had less severe malocclusions than males, on average, although the difference was not statistically significant.
The malocclusion severity threshold for seeking orthodontic treatment appears to be higher in those of lower SES. The study findings highlight the need to improve access to orthodontic treatment for this group.
关于在私人专科诊所接受临床正畸治疗者的社会人口统计学和错颌畸形特征的报道较少。
描述前来接受正畸治疗的个体的治疗前特征。
在新西兰19家私人专科正畸诊所中随机选择前来接受正畸治疗的个体（N = 174）进行检查（在一项为期三年的前瞻性研究开始时），并使用牙科美学指数（DAI）比较他们的错颌畸形情况。
DAI平均得分为35.8（标准差8.4）。除了基于家庭的社会经济地位（SES）外，DAI得分在社会人口统计学方面没有统计学上的显著差异，低收入SES者的平均得分要高得多。大多数接受治疗的患者患有严重或非常严重/致残性错颌畸形。平均而言，女性的错颌畸形不如男性严重，尽管差异无统计学意义。
低收入SES者寻求正畸治疗的错颌畸形严重程度阈值似乎更高。研究结果凸显了改善该群体获得正畸治疗机会的必要性。
