Summary
Immediate dentin sealing (IDS) may reduce tooth hypersensitivity temporarily after indirect restorations. However, current evidence suggests IDS is an elective, not mandatory, procedure for most patients.
Area of Science:
- Dental Materials Science
- Clinical Dentistry
- Restorative Dentistry
Background:
- Immediate dentin sealing (IDS) is supported by laboratory studies for indirect restorations.
- Randomized clinical trials (RCTs) are needed to confirm its mandatory clinical use.
- Assessing patient outcomes like restoration longevity and hypersensitivity is crucial.
Purpose of the Study:
- To evaluate if immediate dentin sealing (IDS) should be a mandatory procedure for all indirect restorations.
- To analyze the impact of IDS on restoration longevity and patient hypersensitivity based on RCT evidence.
Main Methods:
- A systematic bibliographic search was performed in PubMed.
- A manual search of references in literature reviews was also conducted.
- Four RCTs were included in the analysis.
Main Results:
- Meta-analysis of full crown preparations showed reduced hypersensitivity 1 week post-cementation with IDS.
- IDS benefits for hypersensitivity appear limited to the provisional phase and up to 1 week after final cementation.
- One study found no significant difference in restoration longevity between groups.
Conclusions:
- Immediate dentin sealing (IDS) should be considered an elective clinical step.
- IDS may be beneficial for patients and preparations with a higher risk of sensitivity between appointments.
