简要总结
The objective of this study is to evaluate the clinical effectiveness of a new composite resin (SHOFU Beautifil II LS) vs a control (3M/ESPE Filtek Supreme) for use in restoring non carious cervical lesions Class V lesions.
3M ESPE FiltekTM Supreme is one of the composite resin materials that will be used in this study (Group 1). This is a light-activated, flowable restorative composite.
Shofu Beautifil II LS (SI R21204) is a new type of filling material called a Giomer. This is the second composite that will be used in this study (Group 2) Giomer is a collective term for dental materials that will release ions, such as fluoride. Results from previous studies show that the released ions may have beneficial effects on the tooth, including strengthening the tooth.
In each participant, one tooth with a class V lesion will be randomized to group 1, and a second tooth with a class V lesion will be randomized to group 2. The restorations will be observed over 18 months to determine clinical acceptability.
详细描述
This is a single-center, non-blinded, controlled, split mouth, clinical trial 18 months in duration.
The purpose of this clinical trial is to evaluate the effectiveness of a new Giomer restorative system (Shofu Beautifil LS) for use in restoring non carious Class V lesions by comparing it to 3M ESPE FiltekTM Supreme in the following categories:
Clinical Assessments (Documentation at baseline, 6months and 18months):
- Surface Luster
- Surface Staining
- Marginal Staining
- Color Match
- Anatomical Form
- Marginal Adaptation
- Fracture of Material and Retention
- Radiographic Examination
- Patient's View
- Postoperative Hypersensitivity
- Recurrence of Caries
- Tooth Integrity
- Adjacent Mucosa
Sensitivity interview- assessed preoperatively (prior to anesthesia, if needed) at baseline and after restoration placement

结局指标
主要结局
Hickel Criteria
时间窗: Up to 18 months
Clinical assessments (Esthetic properties: surface luster, surface staining, marginal staining, color match, anatomical form, Functional properties: marginal adaptation, fracture of material and retention, radiographic examination, patient's view, and Biological Properties: postoperative hypersensitivity, recurrence of caries, tooth integrity and adjacent mucosa) will be performed by two trained examiners other than the operating clinician using modified Hickel criteria at baseline and follow-up visits. Differences between the two groups for Hickel criteria items will be examined with the Wilcoxon signed-rank test.
