Application of cold to a tooth will temporarily relieve pain in cases of...?

Acute pulpitis
Pulpal necrosis
Dental abscess
Periapical periodontitis

The correct answer is: Pulpal necrosis

Applying cold to a tooth can provide temporary relief of pain in cases of pulpal necrosis. This is because pulpal necrosis is caused by the death of nerve tissues within the tooth, and the application of cold can temporarily numb the affected area, reducing the sensation of pain. However, using cold for acute pulpitis, dental abscess, or periapical periodontitis may not be as effective since these conditions involve inflammation and infection, which can cause ongoing pain even with reduced nerve sensation.
