I read with great interest the article by Andrade et al.1 assessing the impact of developmental enamel defects (DDE) on the quality of life (QoL) among 5-year-old children. The burden of dental defects is globally prevalent and in Europe it ranges between 6-38%.2 Enamel defects are a significant public health problem as they can cause pain and discomfort due to dentin hypersensitivity, and often manifest aesthetically unpleasant discolourations.3.

我怀着极大的兴趣阅读了 Andrade 等人 1 的文章，该文章评估了发育性牙釉质缺陷 (DDE) 对 5 岁儿童生活质量 (QoL) 的影响。牙齿缺陷的负担在全球范围内普遍存在，在欧洲范围为 6-38%。2 牙釉质缺陷是一个重大的公共卫生问题，因为它们会因牙本质过敏而引起疼痛和不适，并且经常表现出不美观的变色。 3.
