Resumen

OBJECTIVES: The aim of the present study was to evaluate in vitro the influence of EDTA on calcium hydroxide paste diffusion through root dentin. MATERIAL AND METHODS: Twenty extracted molars were chosen and had their root canals instrumented and irrigated with sodium hypochlorite 1%. The teeth were randomly divided into two groups. In Group I final irrigation was performed with 17% EDTA in order to remove the smear layer. In Group II the smear layer was not removed. After preparation, calcium hydroxide paste was placed inside the root canals and sealed. After that, each tooth was fixed to an endodontic file and placed inside a flask containing distilled water. The pH value was measured with a manual pH measure for 1, 7, 14, 21, and 28 days. RESULTS: The study has not detected any significant statistical difference between the test groups as to pH values. However, both groups presented an increase in pH values during the observation period. CONCLUSION: The use of 17% EDTA was not relevant to the alkalinized aspect of the external dentine.
