HOSA Dental Terminology Practice

What is another term for aphthous ulcer?

1. Canker sore

2. Cold sore

3. Dental abscess

4. Oral fibroma

The correct answer is: Canker sore

Aphthous ulcers are commonly known as canker sores. These small, painful lesions typically appear inside the mouth, including the soft tissues, gums, and tongue. They are characterized by their round or oval shape and a white or grayish center surrounded by a red halo. Understanding this terminology is important for dental professionals as it helps in diagnosing and discussing oral health conditions explicitly with patients. In contrast, cold sores refer to herpes simplex virus infections that manifest as blisters on or around the lips, which are not the same as aphthous ulcers. Dental abscesses are localized infections in the teeth or gums, usually associated with decay or gum disease, and oral fibromas are benign tumors that can develop in the mouth but are unrelated to the lesions described by aphthous ulcers. Thus, recognizing canker sore as synonymous with aphthous ulcer is essential for proper communication and care in dental settings.
