What are the differences between ultrasonic teeth cleaning and sandblasting teeth cleaning?

There are differences between ultrasonic teeth cleaning and air-polishing in terms of principles, cleaning effectiveness, cost, impact, and suitable populations. A detailed analysis is as follows:

1. Principle: Ultrasonic teeth cleaning utilizes the high-frequency vibration of ultrasound combined with water spray to remove plaque and calculus from the tooth surfaces and beneath the gums. Air-polishing, on the other hand, employs a high-pressure air stream to propel specially formulated powder onto the tooth surfaces. The combined impact of these fine particles and high-pressure water removes stains and pigmentation.

2. Cleaning Effectiveness: Ultrasonic cleaning can reach into all corners of the teeth, effectively removing soft plaque, calculus, and pigmentation, with minimal damage to the tooth surfaces. Air-polishing primarily targets surface stains and pigmentation, such as tea stains and tobacco stains. It can also clean areas that are difficult for ultrasonic instruments to reach, such as pits, fissures, and interdental spaces, removing plaque and pigmentation. However, it is less effective for deep calculus removal.

3. Cost: Generally, ultrasonic teeth cleaning is relatively inexpensive, typically ranging from 50 to 100 yuan. Air-polishing tends to be more expensive, costing approximately 100 to 200 yuan. This price difference may be due to variations in equipment, materials, and the complexity of the procedures involved.

4. Impact: Ultrasonic cleaning causes minimal irritation to the teeth and gums, allowing for precise cleaning of the tooth surfaces and periodontal tissues with a low likelihood of inducing gum bleeding. Although air-polishing effectively removes surface stains and pigmentation, the high-pressure air stream and fine particles may sometimes cause gum bleeding or tooth sensitivity, especially in individuals with sensitive gums.

5. Suitable Populations: Ultrasonic cleaning is suitable for most patients requiring teeth cleaning, particularly those with heavy calculus buildup, gingivitis, or periodontal disease. Air-polishing is more appropriate for individuals with significant tooth pigmentation or those needing removal of residual pigmentation and small calculus deposits after ultrasonic cleaning. The choice of cleaning method should depend on individual oral conditions and needs.

Additionally, it is recommended to undergo regular dental checkups to maintain dental health and aesthetics.
