The clinical application of calcium hydroxide is mainly used in the following three aspects:
First, pulpotomy: the purpose of pulpotomy is to remove the diseased coronal pulp, preserve the healthy root pulp and pulp vitality, maintain the normal absorption and loss of the deciduous tooth root, and promote young permanent teeth. Further development of roots and blockade of the apical foramen.
Second, apical induction plasty: When the root of the young permanent tooth is still in the developmental stage, due to some reasons, such as dental caries, deformity, trauma, etc., the pulp is necrotic, the root development is stopped, and the root tip is in an open state. . The treatment of this kind of tooth has made stomatologists very difficult. Due to the large root canal cavity, it is very difficult to achieve complete debridement by conventional methods of dilating and frustrating the root canal. If the root canal is to be tightly filled Simply impossible. Since the 1960s, foreign countries have done a lot of research work in this area, changing the simple mechanical filling method in the past, but promoting the continuous development of the root tip to reach a new way of blocking the root tip, and achieved remarkable results. That is, first use drugs to promote the completion of root apex development, so that it is blocked, and then do root canal filling. This is called apical induction. At present, the drug with better effect than recognized is the preparation containing calcium hydroxide.
Third, pulp capping: It is a treatment that directly covers the exposed pulp with drugs to promote pulp healing and repair, and is usually suitable for healthy and novel exposed pulp. At present, the clinical effect of calcium hydroxide preparations has been recognized.
