Which is better, chemical curing or light curing?

Curing is better. As filling materials, the latter two are mainly photocurable and chemically cured resins. The chemically cured composite resin material can be self-cured at room temperature, which is convenient for clinical application. Its disadvantages are that the plastic surgery cycle is short, and the operating skills of clinicians are high, and this material is easy to change color with time. Light-cured composite resin. Because it can be made into a component, it does not need to be stirred, the operation is simple, there are no bubbles, the color is good and it can be polished. Because this material will only cure under light, doctors should be given enough operation time in clinical work to facilitate the dressing and shaping of the repair material. The disadvantage is that the light source is harmful to human eyes and skin, so attention should be paid to protection during clinical operation.
