In Vivo Assessment of the Tooth-Resin Composite Interface Using Optical Coherence Tomography

University of Minnesota·interventional·Posted Dec 6, 2021·Updated Oct 28, 2024

In Brief

A clinical study evaluating Composite with 90 degree cavosurface angle and Composite with wide bevel for Cavity and Cavities of Teeth. Completed, enrolled 36 participants across 1 site.

Detailed Summary

The aim of the study is to compare the short-term marginal integrity of two preparation techniques for Class I composite restoration using two visual assessment techniques, the FDI World Dental Federation and US Public Health Service assessment criteria. In addition, Optical Coherence Tomography (OCT) will be used to assess the marginal integrity of the restoration.

Interventions

Composite with 90 degree cavosurface angledevice

Lesion-specific cavity design with 90 degree cavosurface angle throughout the cavity margins will be prepared. The total etch method will be performed, i.e. with a 32% by weight phosphoric acid (3M Scotchbond™ Universal Etchant) on enamel and dentine for 15 seconds. The etchant will be rinsed away and an adhesive (3M Scotchbond™ Universal Adhesive) will be applied on dentine with a microbrush for 20 seconds. The adhesive will be light-cured for 10 sec with the Elipar S10 curing light (3M Oral Care). Subsequently the preparation will be restored with a bulkfill resin composite (3M Filtek™ One Bulk Fill Restorative) and cured for 20 seconds.

Composite with wide beveldevice

Lesion-specific cavity design with wide bevel throughout the cavity margins will be prepared. The total etch method will be performed, i.e. with a 32% by weight phosphoric acid (3M Scotchbond™ Universal Etchant) on enamel and dentine for 15 seconds. The etchant will be rinsed away and an adhesive (3M Scotchbond™ Universal Adhesive) will be applied on dentine with a microbrush for 20 seconds. The adhesive will be light-cured for 10 sec with the Elipar S10 curing light (3M Oral Care). Subsequently the cavity will be restored in with a pre-warmed (using Bioclear Heatsync Kit) bulkfill resin composite (3M Filtek™ One Bulk Fill Restorative) and cured for 20 seconds.
