The purpose of caries treatment is to stop the disease process and restore the inherent shape and function of the tooth.
1. Medication
Drug treatment is a method of applying drugs to inhibit the development of caries on the basis of abrading caries. It is suitable for superficial caries of permanent teeth that have not yet formed a cavity, and shallow and medium caries of primary anterior teeth. Commonly used drugs include silver ammonia nitrate and sodium fluoride.
2. Silver amalgam filling
For teeth with substantial defects, filling is the most widely used and effective method at present. The basic process can be divided into two steps: first remove the carious tissue and the weak tooth tissue that has lost support, and follow certain requirements Make the cavity into a reasonable shape. Then it is filled with filling material to restore its inherent shape and function. It is suitable for filling back teeth and anterior teeth holes in hidden parts.
3. Composite resin filling
It is suitable for filling anterior teeth and posterior teeth that do not bear the force of chewing.
4. Acid-etching photosensitive composite resin filling technique
The indications are the same as those for composite resin fillings, and it is also suitable for more tooth defects, poor retention, and covering discolored teeth.
5. Inlay
A restoration body made of metal or other materials suitable for the cavity of a tooth is embedded in the cavity and called an inlay; the cover inlay is a cover inlay. Applicable to: ①Those with large cavities on the posterior occlusal surface or the posterior teeth with the possibility of fracture; ②Those who cannot repair the adjacency relationship with the adjacent teeth by filling the adjacent occlusal surface; ③As a semi-fixed abutment.
