Questions, answered
Group lesions by whether they wipe off: pseudomembranous candidiasis does, whereas leukoplakia, lichen planus and frictional keratosis do not. Then learn the features that raise concern, such as erythroplakia, non-homogeneous (speckled) leukoplakia, induration and non-healing ulceration. Pair each lesion with its first-line management and whether it needs biopsy or referral.
Prioritize anticoagulant and antiplatelet therapy, bleeding disorders, antiresorptive and anti-angiogenic drugs, poorly controlled diabetes, previous head and neck radiotherapy (risk of osteoradionecrosis) and cardiac conditions that need antibiotic prophylaxis. For patients on warfarin, common guidance is to check a recent INR, ideally within 24 hours, and to proceed with simple extractions using local hemostatic measures if it is below 4. Questions usually ask what to check or change before treatment.
