This editorial provides clarifications on the application of the Stage and Grade classification of periodontitis. In particular it describes: (1) how to apply the extent criterion to the defined Stage of the disease; and (2) how to calculate tooth loss because of periodontitis in Stage III and IV cases presenting with evidently hopeless (irrational to treat) teeth with a clinical definition of such teeth.
本社论就牙周炎的分期和分级分类的应用提供了说明。具体而言，它描述了：(1)如何将程度标准应用于疾病的既定分期；以及 (2)如何计算由于 III 期和 IV 期病例中明显无望（不合理治疗）的牙齿而导致的牙周炎引起的失牙，这些牙齿的临床定义为这样的牙齿。
