Pit and fissure sealants should be checked annually (Figure 34). If some or all of the RBSs has been lost, it should be repaired or replaced to continue preventing caries. Even if the GICs has worn, it will continue to prevent caries. Regular radiographs are helpful to follow the success of this procedure. Parents and patients must be educated about the importance of re-evaluating the sealants and an overall preventive dentistry regimen including proper homecare, fluoride exposure (either systemic and/or topical) and the avoidance of cariogenic foods and drinks. It is important to explain to patients and their guardians that sealants can help reduce the risk of decay on the sealed tooth, but they will not prevent all cavities, especially if diet and hygiene is poor.
