[Clinical observation of CP and iodoform for intracanal medication]

To evaluate and compare the clinical effect of camphophenic (CP) and iodoform used as intracanal medication in root canal therapy for periapical periodontitis, 305 teeth suffering from periapical periodontitis in 245 subjects were divided into two groups. The experimental group of 163 teeth was treated with CP and iodoform, while the control group of 142 teeth was treated with CP alone. The clinical effect after 10 days was observed. The result showed that the response rate in the teeth treated with CP and iodoform was 92.64%, significantly higher than that in the teeth treated with CP alone (79.58%), P<0.01.
