Indirect or direct pulp capping is the use of a capping agent, such as calcium hydroxide or other calcium-containing paste, covering the surface of the cave or pulp, so that the formation of reparative dentin, and to achieve the purpose of the formation of apical. Apical angioplasty is the use of calcium-class preparation for root canal filling; promote dental hard tissue formation, particularly in promoting apical formation, to achieve the purpose of apical closure.

2. Radicular cyst: it is a chronic periapical lesion. Its features are: pulp necrosis, tooth discoloration, dull. The cyst can be very flexible, visual observation of the tooth can not determine its size. In some cases, can touch the gingival mucosa bulge, with ping-pong-like shells sexy.

3. Root broken: odontoclasis site may occur in different parts of the tooth, broken tooth neck, the root the middle broken and periapical broken. Handling odontoclasis no special way to What steps do dental implants encounter odontoclasis cases are taken to solve tooth extraction. Now for the root middle and apical broken cases using internal fixation in the treatment of the root canal.
