[A short-term clinical study of one-visit endodontic treatment for infected root canals].
OBJECTIVE
To clinically evaluate the postoperative pain level and short-term healing of one-visit endodontic treatment for infected root canals.


METHODS
100 infected cases were included in one-visit root canal therapy group and 42 infected cases in two-visit group using calcium hydroxide as an interappointment medicament. A comparison of the clinical results was done between the two groups. The main assessments included postoperative pain evaluated by patients and by clinical examination, and the six months' healing response.


RESULTS
There was no statistically significance between the groups regarding pain 7 days after operation (one visit 60.0%, two visit 57.1%, P > 0.05) and six months' healing response (one visit 67.9%, two visit 61.5%, P > 0.05). The pain in the one-visit group was quickly relaxed postoperatively, as the pain in the two-visit group was given a rise because of the second treatment.


CONCLUSIONS
One-visit endodontic treatment for infected root canals has the same clinical efficacy as two-visit in regarding to postoperative pain level and short-term healing.
