Comparison of dentinal hydraulic conductance according to the application time of oxalate-based desensitizers

Revista Facultad de Odontología Universidad de Antioquia, 2015
Introduction: an in vitro model was used to measure the hydraulic conductance in human dentin discs treated with oxalic acid for 15, 30 or 60 s maintaining the occlusive effect and measuring 7 and 14 days after application.
