Longevity of posterior composite restorations: A systematic review and meta-analysis
Research output: Contribution to journal › Journal article › Research › peer-review
The aim of this meta-analysis, based on individual participant data of
several studies, was to investigate the influence of patient, materials and
tooth related variables on the survival of posterior resin composite
restorations.
Methods: Following PRISMA guidelines a search was conducted 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’s
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.
Results: 2816 restorations (2585 Class II and 231 class I restorations)
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 with a higher number of restored surfaces.
