Abstract：
The 2020 International Association of Dental Traumatology (IADT) Guidelines feature several important changes in the treatment recommendations for traumatic dental injuries (TDIs) from the previous 2012 iteration of these Guidelines. This evidence-based narrative review aims to provide a detailed appraisal of five specific changes incorporated in the 2020 IADT Guidelines, based on the available literature evidence that may have prompted these changes. The paper discusses three excellent additions/changes to the new Guidelines: (i) inclusion of a core outcome set for reporting TDIs; (ii) more conservative management of primary dentition TDIs including the changed recommendations for radiation exposure and managing primary dentition luxation injuries; and (iii) the changes in the treatment recommendations for permanent dentition avulsion injuries. The paper further debates whether two other changes made in the current IADT Guidelines for-(i) intrusion injuries in immature teeth; and (ii) complicated crown-root fractures in mature teeth-have sufficient evidence to support the changed recommendations.
摘要：
2020年国际牙外伤协会（IADT）指南在前次2012年版本的外伤性牙损伤（TDI）治疗建议中出现了一些重要变化。这项基于证据的叙述性审查旨在对2020年IADT指南中包含的五项具体变化进行详细评估。基于现有的文献证据，可能促使这些变化。本文讨论了新指南的三个出色的补充/更改：（i）纳入报告TDI的核心结果集；（ii）对原发性牙列TDI的更保守的管理，包括对辐射暴露和原发性牙列脱位损伤的更改建议；（iii）永久性牙列撕脱伤的治疗建议的更改。本文进一步讨论了当前IADT指南中的其他两项更改-（i）未成熟牙齿的侵入损伤；（ii）成熟牙齿的复杂冠根骨折-是否有足够的证据支持更改的建议。
