Air abrasion as a caries removal technique is less aggressive than conventional techniques and is compatible for use with adhesive restorative materials.

Alumina, while being currently the most common abrasive used for cutting, has controversial health and safety issues and no remineralisation properties.

The alternative, a bioactive glass, 45S5, has the advantage of promoting hard tissue remineralisation.

However, 45S5 is slow as a cutting abrasive and lacks fluoride in its formulation.

The aim of this study was to compare the cutting efficacy of dentine using a customised fluoride-containing bioactive glass Na0SR (38–80 μm) versus the conventional alumina abrasive (29 μm) in an air abrasion set-up.

Fluoride was incorporated into Na0SR to enhance its remineralisation properties while strontium was included to increase its radiopacity.

Powder outflow rate was recorded prior to the cutting tests.

Principal air abrasion cutting tests were carried out on pristine ivory dentine.

The abrasion depths were quantified and compared using X-ray microtomography.

Na0SR was found to create deeper cavities than alumina ( p < 0.05 ) despite its lower powder outflow rate and predictably reduced hardness.

The sharper edges of the Na0SR glass particles might improve the cutting efficiency.

In conclusion, Na0SR was more efficacious than alumina for air abrasion cutting of dentine.
