What does a chronic apical abscess usually develop from?

• A. Acute irreversible pulpitis
• B. Asymptomatic apical periodontitis with pus
• C. Direct trauma to the tooth
• D. Systemic infection

Answer: (B)

A chronic apical abscess typically develops from asymptomatic apical periodontitis with pus. This condition arises when the pulp of the tooth becomes necrotic, leading to the formation of a periapical lesion. In this scenario, the infection becomes chronic and may lead to the accumulation of pus in the surrounding tissues. Asymptomatic apical periodontitis can occur when bacteria invade the dental pulp and cause infection, but without presenting significant symptoms initially. Over time, if the immune response does not adequately address the infection, this can evolve into a chronic apical abscess, where the inflammation and pus become persistent. In contrast, while acute irreversible pulpitis, direct trauma to the tooth, and systemic infections can contribute to dental issues, they do not specifically describe the progression toward a chronic apical abscess in the same way. Acute irreversible pulpitis represents a more immediate, symptomatic condition that could lead to a different path of complication, rather than the chronic nature of the abscess described in the question.
