Root canal therapy refers to the removal of normal, infected or necrotic pulp tissue, root canal preparation and thorough disinfection, and filling the root canal with filling materials. Theoretically, root canal therapy is not needed for dental caries, but only when there is inflammation in the pulp or periapical area. Therefore, as long as we judge whether the tooth decay has developed into pulpitis or periapical periodontitis, we can determine whether the tooth decay needs root canal treatment. When the following symptoms of pulpitis or periapical periodontitis appear, root canal therapy is needed.

1, pulpitis: pulpitis is the result of the further development of tooth decay, which is divided into acute pulpitis and chronic pulpitis. Acute pulpitis will have obvious and severe spontaneous paroxysmal pain, which is easier to diagnose according to these symptoms; Chronic pulpitis is similar to deep caries and has no obvious spontaneous pain, so it is easy to be misdiagnosed as deep caries. Chronic pulpitis has mild pain response to cold and hot stimulation and food impaction, but once induced, the pain lasts for a long time, which is the difference from deep caries.

2, periapical periodontitis: further development of pulpitis can become periapical periodontitis, which can be divided into acute periapical periodontitis and chronic periapical periodontitis. Acute periapical periodontitis has severe spontaneous and persistent jumping pain, so the symptoms should not be confused with deep caries; Chronic periapical periodontitis has no obvious spontaneous pain, but its pulp necrosis is lifeless, and the pulp of deep caries has obvious vitality.
