Split-mouth Study of a New Flowable Composite in Non-carious Cervical Lesions

Not Applicable

Active, not recruiting

• Conditions: Non-carious Cervical Lesions
• Interventions: Device: Restoration of non-carious cervical lesions

• Registration Number: NCT06238999
• Lead Sponsor: Ivoclar Vivadent AG

Brief Summary

The overall objective of this clinical investigation is to evaluate the clinical safety and performance of the new flowable composite TM Flow for treatment of non-carious cervical lesions. Each participant receives two different fillings (test- and control material) in two different teeth. The fillings are assessed according to selected FDI criteria at baseline (7-10 days after filling placement) and after 1, 6, 12, 24, 36 and 60 months.

Arm && Interventions

Group	Intervention	Description
Test goup TM Flow	Restoration of non-carious cervical lesions	The newly developed flowable composite TM Flow will be used for the restoration of NCCLs in the test group. The treatment workflow is very similar to other flowable composites.
Control group Tetric EvoFlow	Restoration of non-carious cervical lesions	The well-established Tetric EvoFlow will be used for the restorations of NCCLs in the control group.

Primary Outcome Measures

Name	Time	Method
Postoperative hypersensitivity	1 month	will be assessed acooriding to FDI criteria

Secondary Outcome Measures

Name	Time	Method
evaluation of functional (e.g. fracture of the material and retention), biological (e.g. caries at restoration margins) and aesthetic (e.g. color match) properties of the restorations	5 years	will be assessed acooriding to FDI criteria
