在深龋治疗中,由于过多削除非感染软化牙本质或健康牙本质,造成露髓,继发牙髓病变。露髓分显性露髓和不显性露髓。显性露髓肉眼能直观地察看,露髓点有明显探痛并有渗血。不显性露髓是肉眼见不到的、相当于髓角位置的微小点孔,造成牙髓与髓腔外界相通状态,其临床特点是肉眼见不到露髓点、无明显渗血点、探痛明显却无准确位置。所谓假性露髓亦属不显性露髓的范畴。假性露髓指牙本质发生进行性脱矿,牙本质小管软化和扩大而牙本质髓侧壁无继发性牙本质生成,窝洞髓壁与牙髓间隔微薄,已经软化和扩大的牙本质小管使窝洞与牙髓潜性连通。作者在本文中把不显性露髓和假性露髓并为一论。
In the treatment of deep caries, due to excessive removal of non-infected softened dentin or healthy dentin, resulting in exposed pulp, secondary to pulp disease. Dew point of the dominant divination and non-dominant demyelination. Dominant deorbing eye can be visually observed, there are obvious pain points Luoru bleeding and bleeding. Non-dominant demyelination is not seen by the naked eye, which is equivalent to tiny holes in the position of the medulla, causing the pulp and the medullary cavity to communicate with the outside world. The clinical feature is that the naked eye can not see the exposed pulp, Pain was obvious but no accurate location. The so-called pseudo-exposed pulp is also a category of non-dominant demyelination. False demyelination refers to the progressive demineralization of dentin, dentin tubule softening and expansion of the dentin medulla oblongata without secondary dentin formation, nest cavity wall and endodontic interval is thin, already softened and enlarged dentin Tubules make the pit hole and pulp communication potential. In this article, the authors make non-dominant demyelination and pseudo-demyelination as a theory.
