Question

If a patient is having a class V restoration on the lower first molar, which type of matrix system would be used?

1) T-band matrix system
2) Sectional matrix system
3) Palodent matrix system
4) Composi-Tight matrix system

Answer 1

For a class V restoration on the lower first molar, the T-band matrix system might be the most appropriate choice, as it can adapt to the contour of the tooth near the gumline.

Step-by-step explanation:

If a patient is having a class V restoration on the lower first molar, the type of matrix system used would likely depend on the specific needs of the restoration and the preferences of the dental professional. However, given the options provided:

1. T-band matrix system
2. Sectional matrix system
3. Palodent matrix system
4. Composi-Tight matrix system

The most suitable choice for a class V restoration, which typically involves the cervical third of the tooth near the gumline, might be the T-band matrix system or similar types that are adaptable to the contour of the tooth in this specific area. Options like the Sectional matrix system and Composi-Tight matrix system are generally used for interproximal restorations (between teeth), whereas the Palodent matrix system is frequently used for posterior restorations but less so for class V lesions.
