Here is presented a simple cervical abrasion case needing soft tissue management, isolation, restoration. Flowable composite was chosen for this restoration.

Fig.4
Isolation with rubber dam and proper clamp.

Fig.5
After moving of soft tissues from the surface, minimal enamel margin preparation, 30 seconds acid etching on enamel, 15 seconds on dentin.

Fig.6
After surface disinfection with chlorhexidine solution and self etch priming on dentin.

Fig.7
Applying adhesive on both dentin and enamel.

Fig.8
