Verified step by step guidance

Step 1: Begin by understanding the anatomy and physiology of sebaceous glands. Sebaceous glands are small oil-producing glands located in the skin, and in newborns, they can sometimes appear as small, white or yellowish bumps.

Step 2: Review the specific terms provided in the question. Fordyce spots are ectopic sebaceous glands that appear on mucosal surfaces, typically in adults, not newborns. Milia are small, white cysts that occur on the skin, often on the face of newborns, but not specifically in the mouth or gums.

Step 3: Examine the term 'Aphthous ulcers.' These are painful sores that occur in the mouth, but they are not related to sebaceous glands and are not common in newborns.

Step 4: Focus on the term 'Epstein pearls.' These are small, white cysts found in the mouth and gums of newborns, specifically caused by trapped keratin in the epithelium. They are harmless and typically resolve on their own.

Step 5: Conclude that Epstein pearls are the correct term for the small, unopened or plugged sebaceous glands that appear in a newborn's mouth and gums, based on their anatomical location and description.
