During the use of the air abrasion technique, a tool that acts like a sandblasting handpiece , sprays the tooth, removing dental caries. A thin spray of water with aluminum oxide particles is directed towards the decayed parts of the tooth. These particles are propelled by pressurized air through the dentist’s handpiece. Caries is being removed as the spray of these particles hits it, while the healthy tooth around it remains intact.
Compared to the “traditional” drill, the advantages are many and include the following:
Air abrasion is ideal for use in children and especially in their back permanent teeth. It can perfectly prepare a posterior permanent molar to receive a sealant with high durability, greater than other common techniques. It can, however, mainly remove the incipient dental caries that are often found on these teeth in children and eliminates the need for a filling!
Air abrasion selectively removes only the dental caries and not the healthy tooth structure around it.
This is very important for children, because they are young individuals where less invasive work maximizes the life of thei teeth. And all these benefits are combined with the positive experience that the child has, since he/she does not hear and feel the familiar drilling sounds.
