During a lap examination, which action is used to inspect the teeth and soft tissue?

• A. Lift the lip to inspect the teeth and soft tissue
• B. Check the occlusion only
• C. Rinse the mouth and observe
• D. Use a mirror only without lighting

Answer: (A)

Retracting and lifting the lip to inspect the teeth and soft tissue is the action that directly exposes the front teeth and surrounding mucosa, including the labial surfaces, gingiva, and vestibular tissues. This broad view is essential for spotting caries, gingival inflammation, ulcers, lesions, redness, swelling, or mucosal abnormalities that might be hidden with the lip in place or without adequate lighting. Checking occlusion looks at bite relationships and how the teeth meet, not the health and appearance of the soft tissues or the visible tooth surfaces. Rinsing the mouth can help clear debris but does not provide a complete view of tissue health, and using a mirror without proper lighting makes it hard to see detail. So lifting the lip to inspect the teeth and soft tissue gives the clearest, most informative view during a lap examination.
