Controlled Clinical Trial of the Effect of Calcium Hydroxide, Mineral Trioxide Aggregate (MTA) and Biodentine (Trademark) as Direct Pulp Capping Materials of Permanent Teeth Affected by Caries, in Children From 7 to 16 Years

Methodology: It is a randomized controlled study. groups signed the informed consent for clinical trial patients, a clinical evaluation of 90 permanent molars teeth through endodontic diagnostic tests and radiograph. will be conducted to determine diagnosis. Will be assigned randomly to the type of material to use and direct pulp teeth affected by caries coating is carried out; Patients will not have knowledge of the material to be used in the coating. The patient will be clinically evaluated at 1 week, 3 months and 8 months, and radiographically; at the beginning and end of the study. In each clinical control endodontic diagnostic tests of heat, cold, electric and percussion will be performed. In radiographic controls take a radiograph control with positioner or surveyor at baseline and 8 months, to evaluate the periapical status. Clinical success will consider that tooth in continuous controls and after 8 months presented vitality and radiographic signs of apical image without injury. Failure unresponsive to consider whether susceptibility testing of cold and electricity in more than one control and presents radiographic image with apical lesion.
