作者把深龋的牙本质分为3层:1.表面坏死牙本质层,是龋坏牙本质的表层,富含细菌,牙本质坏死,没有知觉;2.中间层,牙本质呈软化皮革样感,是细菌感染的最前缘,牙本质小管结构不正常,牙本质有知觉;3.深层,牙本质呈皮革样感,但牙本质小管结构正常,没有细菌感染,牙本质可能再钙化。作者的治疗术式是:第一次处理时只除去表面坏死牙本质层,残留中层及深层,然后用氢氧化钙制剂或氢氧化钙与甲基酚醋酯的混合物或氧化锌丁香油糊剂等复盖残留软化牙本质,然后密封窝洞。10—12周后进
The author divides the deep dentine dentin into three layers: 1. Surface necrosis of the dentin layer, is the surface layer of dental carious dentin, rich in bacteria, dentin necrosis, no perception; 2. The middle layer, dentin was softened leather-like Sense, is the forefront of bacterial infection, dentin tubule structure is not normal, dentin sensory; 3. Deep, dentin leathery, but dentin tubule structure is normal, there is no bacterial infection, dentin may re-calcification. The author's treatment is: the first treatment only remove surface necrosis of the dentin layer, the middle and deep residues, and then with calcium hydroxide preparation or a mixture of calcium hydroxide and methyl phenolate or zinc oxide clove oil paste Cover the residual softening dentin, and then seal the nest hole. 10-12 weeks into the future
