Final answer:
The statement that a pyogenic granuloma occurs more commonly on the maxilla than on the mandible is true. They are overgrowths that often appear in the oral cavity, particularly on the gingiva of the maxilla.
Step-by-step explanation:
Pyogenic granuloma is an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. It is a common growth that often appears in the oral cavity. Traditionally, it has been noted that these lesions occur more frequently on the gingiva of the maxilla than on the mandible. Although less common, they can also develop on the skin and other mucous membranes. The statement that a pyogenic granuloma occurs more commonly on the maxilla is true. When these grow, they can be red, pink, or purple, bleed easily due to high vascularity, and can resemble raw hamburger meat. Pyogenic granulomas are not the same as granulomas associated with tuberculosis, in which a granuloma shell can break down, allowing tubercle bacilli to escape, which is a different pathological process.
