简要总结
The purpose of this study is to evaluate the clinical performance of resin composite restorations refurbished and compare with 2 groups of resins, 1 without treatment and another replaced resins acted as controls. The null hypothesis of this study is that the group of refurbished resins have a similar behavior to the control groups.
详细描述
A cohort of 26 patients aged 18-80 years old (mean: 28.35 years; 42% men, 58% women) with 78 composite restorations (Class I: 39; Class II: 39) were recruited at the Operative Dentistry Clinic at the Dental School of the University of Chile. All participants in the refurbishing groups showed clinical features for the anantomy, roughness and/or luster that deviated from the ideal and were rated Bravo according to the modified United States Public Health Service (USPHS) criteria. New Composites with Alpha values (Replacement group) and acceptable composites (No treatment group) were used as controls. The protocol was approved by the Institutional Research Ethics Committee of the Dental School at the University of Chile (Project PRI-ODO-0207). All patients signed informed-consent forms and completed registration forms

结局指标
主要结局
Changes in quality of restorations
时间窗: 1 year
The quality of the restorations was scored according to the modified USPHS criteria. Two examiners underwent calibration exercises each year (JM and EF). Immediately after the treatment (baseline) and 10 years later, the examiners assessed the restorations independently by direct visual and tactile examination with mouth mirror number 5 and explorer number 23 (Hu Friedy Mfg. Co. Inc., Chicago, IL, USA) and indirectly by radiographic examination (bite wing). The four parameters examined were anatomic form, secondary caries, marginal staining and marginal adaptation. If the difference was recorded between the two examiners, and if they could not reach an agreement, a third clinician, who also underwent the calibration exercises (GM), made the final decision.
