Diagnostic criteria ACUTE SEROUS APICAL PERIODONTITIS ACUTE PURULENT APICAL PERIODONTITIS ACUTE DIFFUSE PULPITIS ACUTE PURULENT PULPITIS Anamnesis complaints The patient feels heaviness and tension in the tooth, which was like the big, longer than others. Gradually there is quite a lot of pain spontaneous nature. The pain is constant, localized, not radiating, worse at night and barely suppressed conventional analgesics. Since the process is constantly evolving, pain intensity grows.Also, can occur characteristic provoked pain. All that can increase blood flow in the area of the tooth and change its mobility, provokes attacks of pain. Yes, there is pain during eating. In the initial stage, however, passive, slow, long-term pressing reduces the pain that is associated with the outflow of fluid from periodontal reducing congestion and compression of nerve endings. Acute spontaneous continuous pain pulsation character. Always points to the aching tooth, he feels as "higher" very painful when pressed or even if touched his tongue while talking. Pain enhance existing by heat, while cold, by contrast. Any physical effort leading to increased pain. Acute spontaneous attack-like pain, from 2 hrs. and more; “light-periods” 10 – 30 min. Pain attacks are increased at night; arises from all types of stimuli in laying position. Irradiation of pain. Spontaneous, pulsate (throbbing), continuous pain, could be weaken for a few minutes. There is an irradiation of pain. Pain is exacerbating at night and from hot stimulus; relieving factor is cold water. Any of the irritants lead to sharp attack of pain. Deepness of carious cavity Sick tooth may be intact, that does not exclude injury (such as when you use orthodontic appliances). Often, however, it is caries, devital, with an open cavity of a tooth filled or a great seal. Enamel loses its characteristic luster, is gray. It is clear in the area of apex often hiperemic and swollen, sometimes existing congestion and adjacent areas gums. The patient's tooth may be intact, although its Deep carious cavity with great amount of color is changed, sometimes significantly decayed dentine. carious defects or filling. Pulpova cavity in most cases closed, but may be open. Probing of carious cavity bottom Probing the bottom of tooth cavity is painless. Probing the bottom of tooth cavity is painless. All bottom of carious cavity is painful; pain is preserved after stopping of probing. Sharply painful probing of all carious cavity bottom; roof of the pulp chamber could be easily perforated and drop of pus could come out. Vertical percussion painful. Very painful Painless Painless Temperature test There are no reactions to temperature irritants. There are no reactions to temperature irritants. Pain due to cold or hot water; pain irradiates following branches of V cranial nerve. Cold water relieve pain for few min. EPT Higher than 100 mA 120-150 mA 20-35 mcА 35 — 45 mcА 1 Deep carious cavity with great amount of decayed dentine
