Calcium Silicate Liner

By the Dental Nation clinical team — a licensed dental group practising in the UAE

Calcium silicate liners include materials such as MTA, Biodentine, and TheraCal LC.

[1][2]

The short answer

Calcium silicate liners such as MTA, Biodentine, and TheraCal LC have been compared with resin-modified glass ionomer beneath composite restorations.

How did their bond strength compare?

In the reviewed studies, resin-modified glass ionomer showed higher shear bond strength than the three calcium silicate liners.

[1][2]

Where are these liners used?

The comparison examined liners in resin composite restorations, including their bond with resin-modified glass ionomer cement.

[1][2]

What is an alternative liner?

Resin-modified glass ionomer was the alternative liner in the comparison and was preferred over calcium silicate materials for this bond-strength outcome.

[1][2]

What does the comparison tell you?

The measured difference concerns shear bond strength at the liner interface in composite restorations, rather than a general verdict on every use of calcium silicate cement.

[1][2]

What failure patterns were reported?

Cohesive failure was reported most often among the liner groups, while adhesive failure followed; resin-modified glass ionomer sometimes showed mixed failure.

[1][2]

Frequently asked questions

Which calcium silicate liner had the lower bond strength in this comparison?

Biodentine had lower bond strength than TheraCal LC and MTA in the reviewed liner comparison.
