What effect does eugenol have on the pulp?

Soothing
Irritating
Neutral
Drying

The correct answer is: Soothing

Eugenol is a natural oil derived from cloves that has analgesic and anti-inflammatory properties, making it soothing for the pulp. Option B is incorrect because eugenol is known to have a numbing effect on the pulp, reducing pain and inflammation rather than causing irritation. Option C is incorrect as eugenol does have an effect on the pulp, rather than being neutral. Option D is incorrect because eugenol is not known to have a drying effect on the pulp, but rather it helps to reduce discomfort and promote healing.
