How does a Chronic Apical Abscess develop? A 3D visualization with VOKA Tooth decay isn’t just about cavities—it can lead to deep infections. When bacteria invade the necrotic pulp inside the root canal, the body responds by forming purulent exudate (pus), which spreads through the bone and creates a fistula for drainage. Because the abscess has an outlet, it often remains silent and asymptomatic, but if the sinus pathway closes, pain can occur. Without proper treatment, the infection can progre

What is a periapical true cyst? Causes, diagnosis & treatment in 3D A periapical true cyst is a completely enclosed, fluid-filled cavity that forms at the tip of a tooth root due to chronic infection and inflammation in the root canal system. Unlike a periapical pocket cyst, which remains connected to the root canal, a true cyst is entirely separated from the root, making it less likely to heal on its own. 🔬 How does it form?
