A Clinical Trial to Evaluate a New Giomer Restorative System in Class V Restorations
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.

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
Dentin Sclerosis Rating- assessed at baseline
duration.
