In the period of adolescence physical appearance takes on significant importance in the construction of personal identity, including one's relationship with one's own body. A variety of social, cultural, psychological and personal factors influences the self-perception of dental appearance and the decision to undergo orthodontic treatment. Adolescents who seek orthodontic treatment are concerned with improving their appearance and social acceptance. The aim of the present study was to determine factors associated to the desire for orthodontic treatment among Brazilian adolescents and their parents.
The sample consisted of 403 subjects aged 14 to 18 years, selected randomly from a population of 182,291 schoolchildren in the same age group. The outcome variable "desire for orthodontic treatment" was assessed through a questionnaire. Self-perception of dental aesthetics was assessed using the Oral Aesthetic Subjective Impact Scale (OASIS) and the Dental Aesthetic Index (DAI) was used for clinical assessment. Statistical analysis involved the chi-square test as well as both simple and multiple logistic regression analyses.
The majority (78%) of the Brazilian adolescents desired orthodontic treatment and 69% of the parents reported that their children were not in orthodontic treatment due to the high costs involved. There was significant association (p < or = 0.05) between the desire for orthodontic treatment and most types of malocclusion. However, there was no significant association between the desire for orthodontic treatment and the variables gender and age.
The following were considered factors associated to the desire for treatment: upper anterior crowding > or = 2 mm and parents' perception of their child's need for treatment.
在青春期，外貌在个人身份的构建中变得非常重要，包括一个人与自己身体的关系。各种社会、文化、心理和个人因素都会影响到人们对牙齿外观的自我认知，以及是否决定接受正畸治疗。寻求正畸治疗的青少年关心的是改善自己的外貌和社会接纳度。本研究的目的是确定与巴西青少年及其父母对正畸治疗的渴望相关的因素。
该样本由 403 名年龄在 14 至 18 岁之间的受试者组成，他们是从同一年龄组的 182291 名在校儿童中随机选择的。“对正畸治疗的渴望”这一结果变量是通过问卷调查来评估的。通过口腔美学主观影响量表（OASIS）评估自我感知的牙齿美学，使用牙齿美学指数（DAI）进行临床评估。统计分析包括卡方检验以及简单和多元逻辑回归分析。
大多数（78%）巴西青少年渴望接受正畸治疗，而 69%的家长表示，由于费用高昂，他们的孩子没有接受正畸治疗。正畸治疗的愿望与大多数类型的错颌畸形之间存在显著的关联（p < or = 0.05）。然而，正畸治疗的愿望与性别和年龄等变量之间没有显著的关联。
以下是与治疗愿望相关的因素：上颌前牙拥挤>或= 2mm 和父母对孩子治疗需求的认知。
