Answer 1

The incorrect statement about a spot-welded band is that it's used primarily in endodontic treatments; they are used in restorative dentistry to support teeth during various procedures.

Step-by-step explanation:

The incorrect statement about a spot-welded band is d) It's used primarily in endodontic treatments. Spot-welded bands are used in restorative dentistry to stabilize and support teeth during procedures, not specifically in endodontic treatments. These bands are indeed secured to the teeth using a spot-welding process and are typically made of stainless steel. Additionally, a specific device is required to create the appropriate weld securing the band onto a tooth. Dentists also frequently use dental amalgams for filling cavities. Amalgams, often containing silver and other metals, are chosen due to their low cost, ease of manipulation, and longevity when compared to alternative materials. However, dental amalgams consist of about 50% mercury by weight, raising concerns over the toxicity of mercury.
