Do caries risk and number of restored surfaces have impact on the survival of posterior composite restorations?
The conclusion of the present meta-analysis of 12 clinical studies based on raw data is that caries risk and number of restored surfaces play a significant role in restoration survival, and that, on average, posterior resin composite restorations show a good survival, with annual failure rates of 1.8% at five years and 2.4% after ten years of service.
In patients undergoing elective cardiac surgery with cardiopulmonary bypass, postoperative quality-of-life measures and pain control during recovery were enhanced when morphine (40 mg) was administered intraoperatively as part of a balanced anesthetic technique compared with fentanyl.
