Air abrasion
**Air Abrasion**
### **Core Concept**
Air abrasion is a dental procedure that uses a stream of fine particles, typically aluminum oxide or silica, to remove tooth decay, plaque, and stains. This technique is also known as micro-abrasion or powder blasting.
### **Why the Correct Answer is Right**
Air abrasion works by using a compressed gas to propel the particles at high velocity, which then impact the tooth surface, removing the unwanted material. The particles are so fine that they do not damage the surrounding tooth structure, making it a conservative approach. The process is also relatively painless and can be used for both diagnostic and therapeutic purposes.
### **Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because air abrasion is not a surgical procedure, unlike a biopsy or incisional biopsy.
**Option B:** This option is incorrect because air abrasion is not a method of tooth whitening, although it can remove surface stains.
**Option C:** This option is incorrect because air abrasion is not a type of dental filling material, but rather a procedure to prepare the tooth for restoration.
### **Clinical Pearl / High-Yield Fact**
Air abrasion is a valuable tool in pediatric dentistry, as it can be used to remove plaque and stains without the need for anesthesia in anxious or fearful patients.
