Individuals with special needs exist throughout the world. The last demographic census (IBGE, 2002) in Brazil indicated that 14.5% of the total population (24.5 million) present some type of impairment. This study aimed to evaluate the prevalence of dental trauma (DT) in individuals with special needs and the first attendance by a dental surgeon of patients admitted to the special care clinic of the School of Dentistry of Universidade Paulista (UNIP), Brazil, between 2001 and 2005.
The sample included 544 individuals with special needs aged 1-20 years old (mean 10.7 ± SD 5.3). Patient medical records were reviewed for demographic and clinical data, including medical diagnosis, gender, age, presence of DT and whether the attendance provided was the first time the patient had sought dental treatment.
The individuals were distributed into 11 subgroups according to medical diagnosis. The DT prevalence determined was 9.2% (n = 50), with no difference in relation to gender. The majority (78.3%) of the individuals were seeking dental treatment for the first time at an advanced age.
The present data suggest that DT prevalence in individuals presenting special needs is more common in permanent dentition and that the first attendance by a dental surgeon is delayed.
世界各地都存在有特殊需求的人群。巴西上一次人口普查（IBGE，2002 年）显示，总人口的 14.5%（2450 万人）存在某种类型的残障。本研究旨在评估有特殊需求人群的牙齿外伤（DT）患病率，以及巴西圣保罗大学牙科学院特殊护理诊所（UNIP）在 2001 年至 2005 年间收治的患者首次由牙医就诊的情况。
本研究纳入了年龄在 1-20 岁（平均 10.7 ± 5.3 岁）之间的 544 名有特殊需求的个体。对患者的病历进行了回顾，以获取人口统计学和临床数据，包括医疗诊断、性别、年龄、DT 存在情况以及患者是否首次寻求牙科治疗。
根据医疗诊断，患者被分为 11 个亚组。确定的 DT 患病率为 9.2%（n = 50），与性别无关。大多数（78.3%）患者首次就诊时年龄较大。
本研究数据表明，有特殊需求的个体中 DT 患病率在恒牙中更为常见，且首次由牙医就诊的时间较晚。
