Trial With Two New Tooth-colored Restorative Materials in Class I/II Cavities
- Conditions
- CariesDefective Restorations
- Interventions
- Device: Bulk fill glass hybrid restorative materialDevice: Alcasite restorative material
- Registration Number
- NCT05748327
- Lead Sponsor
- Ivoclar Vivadent AG
- Brief Summary
This is a randomized-controlled clinical trial to investigate the success rate of two new tooth-colored restorative materials in class I and II cavities over 5 years according to FDI criteria scores (1, 2 and 3).
- Detailed Description
The primary outcome of the study is the SUCCESS RATE of restorations placed with both filling materials in class I and II cavities after 5 years of clinical service. A failure which leads to repair or replacement of the restoration can have esthetic (marginal staining, loss of anatomical form), functional (i.e. fracture of restoration, loss of retention) or biological reasons (i.e. secondary caries). A restoration is defined as a failure (no success) as soon as at least one FDI criterion is scored as 4 or 5.

- Sex
- All
- Target Recruitment
- 58
- Subject's age between 18 and 65 years old
- Class I and Class II (with a cavity margin 1-1.5 mm from the cusp tip) (caries treatment, removal of existing defective amalgam/composite restorations), on premolars/molars

- Hospitalized and medically compromised patients (medical history may not compromise the outcome of the results)
- Pulp exposure or signs of pulpal infection
- No signs of pulpitis or hypersensitivity (Visual analog scale < 3 on biting and temperature sensitivity)
- History of allergy to glass ionomer, acrylate/methacrylate monomers
- Pregnancy
- Chronic disease with oral manifestations or primary oral pathology
- Bad oral hygiene
- High caries rate or periodontal problems
- Absence of antagonists
- Absence of adjacent teeth (except last molar in the row with no neighbour tooth at the distal side)

- Primary Outcome Measures
Name Time Method Success Rate 5 years assessed following FDI criteria on a scale from 1 "very good" to 5 "unacceptable": e.g. post-operative hypersensitivity, surface lustre, staining, fracture of material, retention, occlusal contour and wear, and colour match of restorations (Success: Scores equal to/above 3)
- Secondary Outcome Measures
Name Time Method Survival Rate 6 months to 5 years assessed following FDI criteria on a scale from 1 "very good" to 5 "unacceptable": e.g. post-operative hypersensitivity, surface lustre, staining, fracture of material, retention, occlusal contour and wear, and colour match of restorations (Survival: Score equal to/above 4)
Success Rate 6 months to 3 years assessed following FDI criteria on a scale from 1 "very good" to 5 "unacceptable": e.g. post-operative hypersensitivity, surface lustre, staining, fracture of material, retention, occlusal contour and wear, and colour match of restorations (Success: Scores equal to/above 3)
Quality criteria (Clinical performance) 6 months to 5 years assessed following FDI criteria on a scale from 1 "very good" to 5 "unacceptable": e.g. post-operative hypersensitivity, surface lustre, staining, fracture of material, retention, occlusal contour and wear, and colour match of restorations
