OBJECTIVE
Under the Global Medical Device Nomenclature (GMDN) system, the newly introduced term 'hygroscopic dental cement' (HDC) encompasses MTA as well as cements based on bioceramics, calcium silicate or calcium sulphate. Many HDCs have a long history of use in dentistry. There is a need for a consistent, logical and informed approach to the nomenclature of traditional and novel HDCs.
METHODS
Commercial manufacturers of HDC were contacted requesting information on the compositions of products. Manufacturers that were unknown to the authors, that were unable to be contacted, that wished to be excluded from this paper, or that did not send their information on compositions in due time were not included.
RESULTS
The compositions of commercial HDCs include various hybrids of calcium silicates, calcium aluminates, calcium phosphates, calcium sulphate as well as zinc sulphates. Furthermore, there are variations in the radiopacifier as well as additives that change the handling or setting processes.
CONCLUSION
The inclusion of different additives to HDCs enables variation in handling properties such that they now exist as distinct putties and sealers as well as cements.
目的
在全球医疗器械命名（GMDN）系统下，新引入的术语“吸湿牙科水门汀”（HDC）涵盖了矿物三氧化物凝聚体（MTA）以及基于生物陶瓷、硅酸钙或硫酸钙的水门汀。许多HDC在牙科领域有着悠久的使用历史。需要对传统和新型HDC的命名采用一致、合理且明智的方法。
方法
联系了HDC的商业制造商，索要产品成分信息。未被作者知晓、无法联系到、希望被排除在本文之外或未及时发送成分信息的制造商未被纳入。
结果
市售HDC的成分包括硅酸钙、铝酸钙、磷酸钙、硫酸钙以及硫酸锌的各种混合物。此外，在射线阻射剂以及改变操作或凝固过程的添加剂方面也存在差异。
结论
向HDC中添加不同的添加剂可使操作性能发生变化，从而使它们现在以不同的油灰、封闭剂以及水门汀形式存在。
