What additive is used in the air-polishing technique?

The air-polishing technique primarily utilizes sodium bicarbonate as its additive. This substance is favored in dental hygiene practices due to its effectiveness in removing surface stains and biofilm from teeth. Sodium bicarbonate is a mild abrasive, which allows it to cleanse teeth without causing significant damage to the tooth enamel when applied correctly.

Sodium bicarbonate’s alkaline nature also aids in neutralizing acids produced by oral bacteria, which can help to improve the overall oral environment. Additionally, it has a fine particle size and is soluble in water, making it ideal for use in the air-polishing devices that utilize a combination of air, water, and the abrasive powder.

Understanding this distinctive application of sodium bicarbonate in air polishing is crucial for ensuring effective and safe patient care during dental procedures.
