At present, the most important criterion for the size selection of interdental brushes is the PHD-value (passage hole diameter) according to the ISO standard for interdental brushes ISO 16409:2016. The PHD size range of commercially available products currently lies between 0.6 and 5.2 mm. With the exceptions of special situations, a range between 0.7 and 2.9 mm is sufficient for clinical routine. As most products have longer filaments nowadays, one brush can often be applied for two PHD intervals. Consequently, adequate patient counseling and the individual selection of the appropriate interdental brushes can generally be achieved with an assortment of 12 systematically arranged interdental brush sizes. An application example is the "Heidelberg set" described herein. It is crucial that the correct choice of size is based upon continuously rising PHD-values, and not upon parameters such as stem size, outer diameter of filaments, or similar, as these do not allow for a reliable conclusion regarding the interdental passage. The usage of ISO sizes is also not recommendable due to their insufficient size differentiation.

.目前，根据 ISO 16409：2016 标准，选择牙间刷尺寸的最重要标准是 PHD 值（通过孔直径）。目前市售产品的 PHD 尺寸范围在 0.6 到 5.2 毫米之间。除特殊情况外，0.7 到 2.9 毫米之间的范围足以满足临床常规需要。由于现在大多数产品的刷毛较长，一根牙间刷通常可以用于两个 PHD 间隙。因此，通过 12 种系统排列的牙间刷尺寸的组合，通常可以进行充分的患者咨询和选择合适的牙间刷。应用实例为文中描述的“海德堡套装”。重要的是，尺寸的正确选择应基于不断增加的 PHD 值，而不是基于诸如柄部尺寸、刷毛外径或类似参数，因为这些参数不能对牙间通道做出可靠的结论。由于尺寸区分度不足，不建议使用 ISO 尺寸。（《国际口腔医学杂志》2021 年；52 卷：176-186；doi：10.3290/j.qi.b872241；原文发表于 2020 年《牙周病学》31（1）37-49）。
