Question

During cementation of bands, where is the cement placed?

1) Into the tubes
2) On the tooth
3) On the outer surface of the band
4) On the inner surface of the band

Answer 1

During cementation of bands, the cement is placed on the inner surface of the band. This inner surface is what comes into direct contact with the tooth during orthodontic treatments.

Step-by-step explanation:

During cementation of bands, the cement is placed on the inner surface of the band. This procedure is usually part of orthodontic treatment where bands are fixed around a tooth for anchoring orthodontic appliances. The inner surface refers to the part of the band that will be in direct contact with the tooth. It's crucial for the cement to be on this inner surface to properly adhere the band to the tooth. The structure of a tooth includes various layers such as enamel, dentin, cementum, and the pulp cavity; cementum is a layer that covers the root and helps to anchor the tooth in place, which is similar in concept to how the cemented band will secure orthodontic appliances.
