Question

Why is glass ionomer cement the most commonly used cement for banding orthodontic bands?

1) It contains fluoride that aids in preventing decay under the bands.
2) It has adequate strength to aid in retention with enamel.
3) It is capable of being bonded to the tooth surface.
4) Both A and B are correct.

Answer 1

Glass ionomer cement is favored for orthodontic banding because it contains fluoride, which prevents decay, and has sufficient strength for band retention.

Step-by-step explanation:

Glass ionomer cement is the most commonly used cement for banding orthodontic bands primarily because it contains fluoride that aids in preventing decay under the bands. Additionally, it possesses adequate strength to help retain the bands on enamel surfaces, and it can be effectively bonded to the tooth surface.

Fluoride is well known for its anti-caries properties, as it becomes incorporated into the hydroxyapatite of tooth enamel, making it more resistant to acid attack. It also helps with the uptake of calcium and phosphate, promoting remineralization of the tooth surface. Therefore, both A and B are correct, contributing to the protective and retentive benefits of using glass ionomer cement in orthodontic procedures.
