Symptoms of periapical periodontitis

summary

Periapical periodontitis refers to the chronic inflammatory reaction of periapical tissue due to long-term infection and pathogen stimulation in the root canal, which is characterized by the formation of inflammatory granulation tissue and destruction of alveolar bone. So, the symptoms of periapical periodontitis, I'll tell you about it.

Symptoms of periapical periodontitis

Periapical granuloma: periapical lesions of bone tissue destruction, replaced by granulation tissue. There were lymphocytes, plasma cells, phagocytes and a small number of neutrophils infiltration in granulation tissue, and proliferation of fibroblasts and capillaries. The granulation tissue was surrounded by fibrous capsule and proliferated by cord like or reticular epithelium.

Periapical cyst: usually without conscious symptoms, the cyst enlargement makes the jaw wall thin and bulge, palpation has ping-pong like feeling. X-ray showed that there was a well-defined bone sparse area around the apex, and there were obvious white lines around it. The rupture and infection of cyst can form sinus.

Periapical abscess or chronic alveolar abscess: chronic suppurative inflammation confined to periapical area. There were mainly polymorphonuclear leukocytes and monocytes in the pus, and there were dense lymphocytes and plasma cells around them. Periapical abscess can pass through alveolar bone and mucosa to form gingival sinus, or through skin to form skin sinus. Generally, there were no conscious symptoms, slight pain and a history of repeated swelling during percussion.
