Comparing marginal microleakage in Class V cavities restored with flowable composite and Cention-N using confocal microscope-an study.

Context: Class V cavity presents a clinical challenge in the field of restorative dentistry as the margin placement is partially in enamel and partly in cementum, and the trouble associated with this design is the microleakage at the tooth restoration interface.

Aims: To evaluate and compare marginal microleakage in Class V cavities when restored with flowable composite and Cention-N restorative material.

Methods And Material: This in-vitro study was performed on 30 human maxillary premolars, which were extracted for orthodontic reasons.
