The pulp is oxygen and nutrients to the organization of the supply of teeth. When the pulp by some factors, so that the pulp tissue hypoxia, causing necrotic lesions of the pulp tissue, medically known as pulp necrosis. Lead to pulp necrosis what are the reasons?
1. Chemical drug stimulation: such as phenol disinfection cavities, phenol and strong penetration can damage the pulp tissue. Another example is the silver nitrate for cavity disinfection, if used improperly, it will damage the pulp tissue.
2. Dental trauma: tooth because of the injury, the organization of the apical and the apical and thrombosis within the root canal, resulting in dental equipment pulp necrosis Medical Education Network has collected.
3. Dental caries complement: Fix free material, material such as silicon cement powder free acid stimulate the pulp caused necrosis. According to the data to show, filling the teeth of the silicate cement powder, the beginning of a significant inflammatory cell infiltration, made Odon oblast layer disorder, 5-8 weeks, the pulp was moderate to severe inflammation, with abscess formation. Another example of composite resin materials in the left end of saturated gene pulp stimulation.
