Summary
Dentin moisture does not impact postoperative sensitivity (POS) in posterior dental restorations using a simplified etch-and-rinse adhesive. Mild sensitivity may occur initially, but it does not differ between dry and wet dentin groups.
Area of Science:
- Dental Materials Science
- Clinical Dentistry
- Restorative Dentistry
Background:
- Postoperative sensitivity (POS) is a common concern in dental restorations.
- Understanding factors influencing POS is crucial for improving patient outcomes.
- Dentin moisture management during adhesive procedures remains a topic of clinical interest.
Purpose of the Study:
- To evaluate the influence of dentin moisture (dry vs. wet) on postoperative sensitivity (POS).
- To assess POS in posterior restorations using a simplified etch-and-rinse adhesive and bulk-fill resin composite.
- To determine the long-term clinical performance of these restorations up to 12 months.
Main Methods:
- A double-blind, randomized clinical trial involving 45 patients and 90 posterior restorations.
- Application of a simplified etch-and-rinse adhesive on either dry or wet dentin.
- Restorations were completed using a bulk-fill resin composite under rubber dam isolation.
- Postoperative sensitivity and secondary parameters were evaluated at multiple time points up to 12 months.
Main Results:
- No significant difference in spontaneous or stimulated POS was found between dry and wet dentin groups.
- A higher incidence of spontaneous POS (18.6%) was observed within 48 hours post-placement for both groups.
- The intensity of early POS was mild, with no significant difference between dentin moisture conditions.
- Secondary parameters like marginal adaptation and discoloration showed no significant differences between groups.
Conclusions:
- Dentin moisture level does not influence postoperative sensitivity in posterior restorations bonded with simplified etch-and-rinse adhesives.
- The use of bulk-fill resin composites with etch-and-rinse systems demonstrates predictable clinical performance regardless of dentin moisture.
- Clinicians can be reassured that dentin moisture management may not be a critical factor for POS in this specific clinical scenario.
