Air abrasion: an old technology reborn

Area of Science:

• Restorative Dentistry
• Dental Technology

Background:

• Air abrasion technology, utilizing kinetic energy from aluminum oxide particles, has seen a resurgence in restorative dentistry.
• Numerous air abrasion units with varying features and price points ($1,000-$20,000+) are now available.
• Manufacturers promote benefits such as microdentistry and anesthesia-free tooth preparation.

Discussion:

• The claim of achieving smaller, less invasive tooth preparations with air abrasion compared to traditional burs is operator-dependent.
• Air abrasion's utility in identifying incipient carious lesions in stained grooves warrants further investigation.
• Despite limited clinical studies, the adoption of air abrasion in dental practices is increasing.

Key Insights:

• Air abrasion offers a method for cutting tooth structure using projected particles.
• The concept of microdentistry suggests less invasive preparations are possible.
• The need for local anesthesia may be reduced in some air abrasion procedures.

Outlook:

• Further clinical studies are necessary to validate the efficacy and claims associated with air abrasion.
• Understanding the optimal application of air abrasion in various dental scenarios is ongoing.
• Expert insights suggest air abrasion can augment existing restorative dentistry techniques.
