Evaluation of the dimensional stability of some national root canal sealers containing zinc oxide and eugenol

Introduction and objective: Dimensional stability of the root canalsealers containing Endofill , Intrafill , Cimento de Rickert , Pulp-Fill and Target was evaluated through the American Dental Association Specification n.o 57. Material and methods: The stability was evaluated through the arithmetic average of 5 measurements realized with pachymeter, of the sample length, before and after they have been immersed for 30 days in recipients filled with distilled deionized water at 37°C. Results: The results were analyzed using Shapiro-Wilk,Kruskal-Wallis and Mann-Whitney statistical tests (p<0,05). Endofill ,Cimento de Rickert and Pulp-Fill showed contraction within the specifications allowance. Conclusion: Although showing compatible results with the clinical necessity, Target and Intrafill sealers expanded exceding the specification tolerance.
