Two stages of acute periapical

Limitations painful inflammation of acute periapical around the root apex, according to the development process can be divided into two stages of acute serous periapical and acute supportive periapical periodontitis.

Acute serous periapical lesion, the patient is no spontaneous pain, or only feel a slight dull pain, roll up our sleeves but comfortable, this is because of the occlusion pressure the periapical congestion of blood vessels within the blood squeezed out. With the increase in inflammatory exudate, the teeth bite pain is increasingly evident, there is the feeling of elongation. Pain persistent and dental equipment limitations of oral examination revealed teeth knocking severe pain, or even loose, palpable pressure the apical corresponding parts can also cause pain, the patient can clearly pointed out that the teeth in position. Pulp necrosis, visible tooth discoloration and loss of gloss.

Acute supportive periapical often acute serous periapical evolved, but also by chronic periapical periodontitis caused by acute exacerbation. At this point, the periapical periodontal ligament necrosis, degeneration, accumulation of pus, severe pain was pulsatile, the patient can not bite. Pus from periapical proliferation of subperiosteal swelling more obvious. Patients were suffering face apical gingival flushing, swelling, mucous turning point of the shallow, flattened, palpable pain and deep sense of volatility, the corresponding cheek soft tissue showed reactive edema, regional lymph nodes, palpable pain and lower molars suffering disease may be associated with the opening limited.

In severe cases, even fatigue, fever, irritability, constipation and Harmful to dental health of the denture other systemic symptoms may be associated with the maxillofacial corresponding at cellulitis. To submucosal abscess stage pain relief, percussion pain relief, domed uplift of the apical mucosa was limited palpation sense of volatility and systemic symptoms. Acute periapical X-ray showed: no significant change or only the periodontal space was widened for chronic periapical attack from the transmission image, showing the apical alveolar bone destruction.
