- OBJECTIVE: To evaluate the onset of analgesic effect for a new formulation of ibuprofen sodium dihydrate versus conventional ibuprofen (ibuprofen acid). MATERIALS AND METHODS: In this randomized, double-blind, double-dummy, crossover trial, patients requiring surgical removal of two impacted or partially impacted mandibular third molars received: ibuprofen sodium dihydrate 400 mg plus conventional ibuprofen placebo (Group 1); or conventional ibuprofen 400 mg plus ibuprofen sodium dihydrate placebo (Group 2) following the first surgery. Patients were then crossed over to the alternative treatment. RESULTS: 72 patients were enrolled in Group 1 and 72 patients in Group 2. Ibuprofen sodium dihydrate produced faster initial pain relief than conventional ibuprofen as assessed by time to first pain relief (24.6 vs. 30.5 minutes; p = 0.004), and patient-assessed pain relief at 15 minutes ("some" to "complete" pain relief: 43% vs. 29%; p < 0.001) and 30 minutes (82% vs. 63%; p < 0.001) and pain intensity at 30 minutes (p < 0.001). Substantial pain relief with ibuprofen sodium dihydrate was twice that of conventional ibuprofen at 30 minutes (11% vs. 5%; not significant); 29% and 33% of patients did not reach substantial pain relief at 120 minutes. There were no adverse events leading to treatment discontinuation and only two serious adverse events (oral abscess and facial paresis with conventional ibuprofen) considered unrelated to treatment. CONCLUSIONS: Ibuprofen sodium dihydrate was as effective as conventional ibuprofen, but had a faster onset of initial pain relief and significantly reduced pain intensity within the first 30 minutes after administration, providing rapid clinically meaningful pain relief for patients.

- The aim of this meta-analysis, based on individual participant data from several studies, was to investigate the influence of patient-, materials-, and tooth-related variables on the survival of posterior resin composite restorations. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we conducted a search resulting in 12 longitudinal studies of direct posterior resin composite restorations with at least 5 years' follow-up. Original datasets were still available, including placement/failure/censoring of restorations, restored surfaces, materials used, reasons for clinical failure, and caries-risk status. A database including all restorations was constructed, and a multivariate Cox regression method was used to analyze variables of interest [patient (age; gender; caries-risk status), jaw (upper; lower), number of restored surfaces, resin composite and adhesive materials, and use of glass-ionomer cement as base/liner (present or absent)]. The hazard ratios with respective 95% confidence intervals were determined, and annual failure rates were calculated for subgroups. Of all restorations, 2,816 (2,585 Class II and 231 Class I) were included in the analysis, of which 569 failed during the observation period. Main reasons for failure were caries and fracture. The regression analyses showed a significantly higher risk of failure for restorations in high-caries-risk individuals and those with a higher number of restored surfaces.
