Three kinds of root canal sealers in one-visit root canal therapy: a comparison of clinical outcomes

Abstract

Objective To evaluate the clinical outcomes of three different sealers for one-visit root canal therapy.Methods A total of 362patients/425teeth diagnosed as pulpitis were randomly divided into three groups:group A,including 120patients/121teeth,treated with zinc oxide engenol(ZOE);group B,including 121patients/151teeth,treated with Cortisomol;and group C,including 121patients/153teeth,treated with 2Seal easymiX.All the teeth were filled with gutta percha by cold lateral condensation.The post-treatment pain and the one-year successful rate were observed.Results The incidence rate of post-treatment pain in group A(15.7%[19/121])were significantly higher than those in group B(5.3%[8/151],P0.01)and group C(6.5%[10/153],P0.05);and there was no significant difference between group B and C.The one-year successful rates were not significantly different between group A(94.0%[110/117]),B(96.5%[137/142])and C(97.9%[142/145]).Conclusion The three kinds of root canal sealers can all achieve satisfactory one-year successful rate in one-visit root canal therapy;moreover,Cortisomol and 2Seal easymiX can also reduce post-treatment pain,making them ideal root canal sealers.
