Advantages and disadvantages of pit and fissure sealing
Pro: coating a layer of sealing material on the pit and fissure seal is equivalent to adding a protective film on the surface to prevent tooth decay. The best time to seal the gingival sulcus is when the teeth have completely erupted and no dental caries have occurred. The deciduous molars are 3-4 years old, the first permanent molars are 6-7 years old, the second permanent molars are113 years old, and the bicuspids are 9- 13 years old.

Disadvantages: The most important link of pit and fissure sealing is bonding, and the bonding effect depends on the doctor's moisture isolation during the operation. If the moisture barrier effect is not good, the adhesion will be poor, and the pit and fissure sealant will fall off more easily. Once the pit and fissure sealant falls off, the incidence of dental caries is higher than that of children without pit and fissure sealant.

Precautions:

1, within a few days after the child has just finished pit and fissure sealing, if it is found that the closed teeth have high occlusion and feel uncomfortable and painful when eating, it is necessary to see a doctor in time and let the doctor run at the part where the filling material is higher than the teeth. If it is found that some or all of the filling materials fall off, the pit and fissure should be re-closed in time, otherwise the effect of caries prevention cannot be achieved.

2. If the pit and fissure sealant is not tightly sealed or falls off, the sealing will be invalid and the exposed pit and fissure may be decayed again. Therefore, it is very important to review the pit and fissure regularly after the pit and fissure is closed, which should be carried out 6 months after the pit and fissure is closed and then reviewed once a year. If it falls off, it needs to be closed again.

3. Pit and fissure sealing can reduce the chance of occlusal caries, but it has no obvious preventive effect on adjacent caries. Therefore, pit and fissure sealing is not the complete insurance of teeth, but it is still necessary to brush your teeth carefully. This most basic caries prevention measure cannot be ignored.
