Which check is performed first in Check 2?

• A. EO and IO exams
• B. Extraoral only
• C. Intraoral only
• D. No exams

Answer: (A)

Check 2 starts with a combined extraoral and intraoral examination. This full-scope check is essential because it gives a complete picture of the patient’s condition, capturing what lies on the outside of the face as well as inside the mouth. By evaluating facial symmetry, skin and mucosa, lymph nodes, and any visible signs of trauma or disease along with the condition of teeth, gums, tongue, and other oral tissues, you establish a solid baseline for planning care. Starting with both EO and IO exams helps you spot problems early and decide what to investigate next, such as radiographs or targeted tests.

Relying on only an extraoral examination could miss intraoral issues like caries, mucosal lesions, or occlusal problems. Conversely, doing only an intraoral exam might miss facial swellings, lymph node changes, or other extraoral clues. Skipping exams altogether would leave potential problems undetected and compromise safety and thoroughness.
