简要总结
The most commonly used materials in the treatment of decayed teeth are amalgam and composite resins. Because amalgam cannot meet the aesthetic expectations of patients and the rapidly increasing belief that it is toxic, its use has decreased considerably. Although composite resins are primarily used in anterior teeth because they provide aesthetically satisfactory results, they have also become the most preferred material in posterior teeth. This shift is largely due to the significant advancements in their mechanical properties, such as improved strength and durability. Indirect restorations have begun to be used to overcome the disadvantages of resin composites applied with the direct method. Both composite resins and ceramics have given good results for such restorations. However, composite resins have the advantage of being cheaper, more user-friendly, and repairable than ceramics. Laboratory-prepared composite inlays/onlays are more wear-resistant than direct composites, especially in occlusal contact areas. Therefore, they are generally indicated for the restoration of large cavities. Considering the material loss caused by crown restorations and the disadvantages of direct composites in the treatment of teeth with extensive caries, we aimed to treat indirect resin composites that we can apply by making more minimally invasive preparations while supporting the dental tissues.
详细描述
This study was a double-blind randomized controlled clinical trial involving both evaluators and patients. The research compared indirect restorations with direct restorations. Patients receiving treatment were recalled for follow-ups after one week, six months, and twelve months. Restorations were assessed clinically based on modified FDI criteria, which included marginal discoloration, color match, anatomical form, fracture and retention, marginal adaptation, contact point, postoperative sensitivity, secondary caries, and periodontal response. Qualified clinicians conducted the evaluations using a mirror and probe under reflector light. Additionally, bite-wing radiographs were obtained from patients during the 6-month and 12-month follow-ups to assess the development of secondary caries. Differences between adhesives at each time point were analyzed using Fisher's Exact test, while the effect of time on restorations was evaluated with the Wilcoxon Signed Rank test (p < 0.05).
