Postobturation pain and therapeutic effects of Cortisomol sealer and zinc oxide eugonol added iodoform in single-visit root canal therapy

Objective: To compare the postobturation of pain and the therapeutic effects of Cortisomol sealer and zinc oxide eugonol added iodoform in single-visit root canal therapy. Methods: 103 teeth were randomly divided into 2 groups. All teeth were treated with root canal therapy in single-visit. Cortisomol sealer and zinc oxide eugonol plus iodoform were used respectively in treatment. The pain intensity within 1 week after treatment was evaluated by visual analogue scale. The therapeutic effects were evaluated by follow up of 12 months. Results: The pain intensity of the former group were not significantly lower than that of the latter group in 7 d (P 0.05), but in 2 d (P 0.01). After 12 months, efficiency rate of the former group was higher than that of the latter group without significant difference (P 0.05). Conclusion: Root canal therapy using Cortisomol sealer can significantly decrease postoperative pain.
