1 Here's an image of the hard palate. A 70-year-old woman presents with a growth that "falls down" unless she keeps her maxillary denture in place to "hold it in." This growth has been present for one year. She wears her denture, which does not fit well, all day and night and is waiting for her dentist to make a new one. Note the diffuse erythema with slight papillary hyperplasia at the midline of the palate. 3 A 32-year-old woman presents for evaluation of recurring ulcerations on the tongue. She's had them for years, but they became more frequent in the past year. They last 10-14 days and are moderately painful, with spicy or acidic foods worsening the pain. She has tried topical anesthetics and "miracle mouthwash" without relief. 5 A 72-year-old woman with a history of medication-induced xerostomia presents with burning of the oral mucosa and an unpleasant taste that began two weeks ago. Clinical exam reveals diffuse, white curdlike lesions surrounded by mild erythema. These lesions wipe off with gauze and leave an erythematous base. 2 An 82-year-old man presents with an ulceration in the vestibule of the mandibular anterior region (#24/25 area). It has been present for six months without healing. The maxilla and mandible are edentulous. The patient wears only a maxillary denture and does not have a history of tobacco use, and there are no other lesions present in the oral cavity. A clinical exam reveals that the maxillary teeth fit into the ulceration as the patient closes his mouth. 4 A 52-year-old woman presents with "rough areas" on the right and left buccal mucosa. They appear white from self-inspection, but are not painful. She noticed them about a month ago. Pictured above is the right buccal mucosa; the left appears identical. The white lesions cannot be wiped off with gauze. dentaltown.com \\ SEPTEMBER 2017 61http://www.dentaltown.com
