Ch. 22 Case Study A 37-year-old male visited his family dentist for a prophy. During the oral exam, a white plaque was noted on the dorsal tongue. When questioned about the lesion, the patient stated he was aware of the white patch on the tongue and that it had been present for approximately two weeks. The patient denied any pain or burning in the affected area, reporting that the lesion had not appeared to increase or decrease in size. At the time of the dental appointment, the patient appeared to be in a general good state of health. He reported a recent use of antibiotics for an upper respiratory infection. No other health problems were noted, and no medications were being taken by the patient at the time of the dental examination. The patient's dental history included regular examinations and routine dental treatment. The patient's vital signs were all found to be within normal limits. Examination of the head and neck region revealed no palpable lymph nodes. No significant or unusual findings were discovered during the extraoral examination. Intraoral examination revealed a white plaque on the midline of the posterior dorsal tongue measuring approximately 1.5 cm in diameter. The lesion could not be removed by wiping or scraping. Further oral examination revealed no other lesions present. Questions: 1. Based on the clinical information available, what is the most likely diagnosis? 2. What is the organism responsible for this infection? 3. Is this organism part of the normal human microbiota? 4. Describe a couple of factors that may predispose a person to this infection. 5. How should you treat this disease?
