Which isolation technique involves a removable material that can cause latex sensitivity?

The isolation technique that involves a removable material associated with potential latex sensitivity is the dental dam. This product is typically made of latex, which can trigger allergic reactions in some individuals. By using a dental dam, practitioners can effectively isolate the operative field and prevent contamination from saliva, blood, or other materials. However, because dental dams are commonly made from latex, they pose a risk for patients with latex allergies.

On the other hand, the other isolation techniques listed—cotton rolls, Isolite, and dry angles—do not involve the same latex materials. Cotton rolls are usually made from synthetic fibers and do not typically provoke latex sensitivity. Isolite, being a reusable suction device, is often constructed from materials that are not made from latex, and dry angles are primarily absorbent pads that also do not contain latex. This distinction highlights why the dental dam is specifically noted for its connection to latex sensitivity concerns.
