Summary
This study found no significant difference in postoperative sensitivity between self-etching and total-etch adhesive systems for composite resin restorations. Both methods demonstrated minimal sensitivity, with no spontaneous issues reported long-term.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
Background:
- Postoperative sensitivity is a common concern with composite resin restorations.
- Adhesive systems play a crucial role in restoration success and patient comfort.
Purpose of the Study:
- To compare the postoperative sensitivity of posterior Class I composite restorations.
- Evaluate sensitivity associated with self-etching versus total-etch one-bottle adhesive systems.
Main Methods:
- 104 restorations in 52 patients were placed by a single clinician.
- Restorations used Clearfil SE Bond (self-etch) or Single Bond (total-etch) adhesives.
- Sensitivity assessed via cold stimuli and visual analogue scale at multiple time points (0, 7 days, 6 months).
Main Results:
- No statistically significant differences in sensitivity were observed between the two adhesive systems at any evaluation point.
- No spontaneous postoperative sensitivity was reported by patients throughout the 6-month follow-up period.
Conclusions:
- Both self-etching and total-etch one-bottle adhesive systems yield comparable, low levels of postoperative sensitivity for Class I composite restorations.
- The evaluated adhesive systems did not result in spontaneous sensitivity up to 6 months post-restoration.
