Key Points
- The effectiveness of resin-based sealants has been demonstrated repeatedly and depends upon sealant retention. Glass ionomer sealant materials’ retention rates are inadequate. ODH-funded programs are required to use resin-based materials.
- Resin-based sealant materials that may be appropriate in comprehensive dental care settings, such as private practices and safety net clinics, may not be the most appropriate for school-based dental sealant programs. Programs must select the sealant material that works best in the conditions under which they operate.
- Meticulous isolation of tooth surfaces to avoid saliva contamination combined with etching for 15 to 20 seconds with 30 to 40 percent phosphoric acid is the standard for successful bonding of sealants to enamel.
- Sealants should be evaluated for complete coverage and absence of voids or bubbles immediately after placement, and sealants should be repaired if necessary.
- Retention checks can detect clinical problems related to sealant materials, equipment, or application techniques.
- Short-term retention checks are conducted within 2 months after sealant placement to identify early any problems with sealant retention.
- Long-term retention checks are conducted approximately 1 year after sealant placement and are conducted by the examining dentist.
