Effectiveness of Three Oral Devices as Mouthguard in Electroconvulsive Therapy. Randomized Crossover Clinical Trial.

This observer-blind crossover intervention study aims to determine the most effective type of device as oral mouthguard in modified-Electroconvulsive Therapy (m-ECT) comparing three types of devices: standard, prefabricated and manufactured in the dental laboratory. Patients from the ECT Unit of Psychiatric Department of the University Hospital of Bellvitge will use the three devices at a random sequence during the twelve treatment sessions, so each device (A, B, C) will be used for two weeks, that is, for four consecutive sessions.
