Dental treatment modalities for ectodermal dysplasia (ED) vary markedly depending on the clinical manifestations, but to date there have been no studies exploring the potential economic impact of ED. On the basis of anecdotal and clinical reports, the authors postulate that costs of dental treatment for this condition can have a substantial financial impact on patients and their families.
The purpose of the authors' pilot study was to develop an economic model for various treatment modalities for ED with severe hypodontia.
The authors first used a comprehensive review of the literature and expert consensus to establish a treatment modalities model for ED. Next, they completed chart reviews to validate the model with sample treatment and costs information. Using these data, they then constructed a model of treatment options and associated costs.
The sample included 24 patients with ED who had severe hypodontia. Forty-two percent were female; patients' ages ranged from 4 years, 11 months to 31 years, 1 month. Forty-two percent had dental insurance coverage, while more than one-half paid for services out of pocket. An estimated 84 percent had undergone prosthodontic treatment, 37 percent orthodontic treatment and 19 percent implant surgery. Depending on the age of the patient and types of dental treatment, there was a broad variation in costs. This ranged from $2,038 to $3,298 for those who had received prosthodontic treatment only; it ranged from $12,632 to $41,146 for those who had received a combination of prosthodontic, orthodontic and implant treatment.
Dental treatment for ED had a marked financial impact on patients and their families and varied depending on the type and duration of treatment.
外胚层发育不全（ED）的牙科治疗方式因临床表现而异，但迄今为止，尚无研究探讨ED潜在的经济影响。基于轶事和临床报告，作者推测这种疾病的牙科治疗费用会对患者及其家庭造成重大经济影响。
作者进行这项初步研究的目的是为患有严重牙列缺损的ED患者的各种治疗方式建立一个经济模型。
作者首先通过全面的文献综述和专家共识建立了ED的治疗方式模型。接下来，他们完成病历审查，以用样本治疗和成本信息验证该模型。然后，利用这些数据构建了一个治疗方案及相关成本的模型。
样本包括24例患有严重牙列缺损的ED患者。其中42%为女性；患者年龄从4岁11个月到31岁1个月不等。42%的患者有牙科保险，而超过一半的患者自掏腰包支付服务费用。估计84%的患者接受过修复治疗，37%接受过正畸治疗，19%接受过种植手术。根据患者年龄和牙科治疗类型的不同，费用差异很大。仅接受修复治疗的患者费用在2038美元至3298美元之间；接受修复、正畸和种植联合治疗的患者费用在12632美元至41146美元之间。
ED的牙科治疗对患者及其家庭有显著的经济影响，且因治疗类型和持续时间而异。
