Which of the following is not a feature of acute necrotizing ulcerative gingivitis (ANUG)?
a. Soreness and bleeding of the gingivae
b. Necrosis of the gingival papillaec. Halitosis
d. None of the above
The correct answer is D: The clinical features of ANUG are soreness and
bleeding of the gingivae, together with the development of crater-like ulcers,
due to the necrosis of the gingival papillae (Fig. 4.1). This ulceration
subsequently spreads along the gingival margin. Patients develop a marked
halitosis, which has a characteristic odour (Table 4.1). In a few patients with
ANUG there are fever, malaise, and lymphadenitis
