Pit and fissure sealing method and assembly

The invention provides a pit and fissure sealing method and assembly. The method comprises the following steps: filling a pit and fissure sealing agent into a pit and fissure of tooth; covering the surface of the pit and fissure sealing agent at the pit and fissure of tooth with a layer of film; covering a layer of gasket on the surface of the thin film; after occlusion, the gasket is taken off; and removing the film after curing. According to the invention, after the pit and fissure sealing agent is filled, the surface of the pit and fissure sealing agent at the pit and fissure of tooth is covered with a layer of thin film, so that the pit and fissure sealing agent is flush with the occlusal surface, then the thin film is covered with a layer of gasket, and the gap between the upper tooth and the lower tooth is filled with the thickness of the gasket. By the above method, firstly, the cured pit and fissure sealing agent is prevented from being higher than the tooth surface, and secondly, the profile mismatch
