Filter by:This study is conducted to compare the efficacy of surface pretreatment using air abrasion sandblasting aluminum oxide particles (Al2O3) versus not pretreatment in the repair capacity of defective composite restoration indicated for repair.
the patient (n=60), with at least 3 composite resins with marginal defects , randomized into 3 groups A=Sealed with flow composite reinforced with nanofiller , B= Sealed with resin sealant , and C=Control, without intervention , and then assessed by the FDI criteria for clinical performance and longevity of restorations
Objectives: The aim of this prospective, randomized, triple-blind cohort study was to assess the longevity of repairs to localized clinical defects in composite restorations that were initially scheduled to be treated with a restoration replacement Methods: 28 patients aged 18 to 80 years with 50 composite restorations were recruited.Restorations with clinically diagnosed secondary caries (Charlie) or undercontoured anatomical form defects (Bravo) were randomly assigned to the Repair (n = 25) or Replacement (n = 25) group, the quality of the restorations was scored according to the modified USPHS criteria. A Wilcoxon test was performed for comparisons between the same groups (CI=0.05). A Friedman test was utilized for multiple comparisons between different years of the same group.
