Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome will be the maintenance of pulp vitality, analyzed through the absence of spontaneous pain, fistula, edema, and sensitivity to vertical and horizontal percussion. In the test group (RSTC) the thermal sensitivity test (-20ºc) and measurement of oxygen saturation of teeth in 7 days / 180 days and then up to 5 years after treatment. Periapical radiographic analysis with no periapical process and/or root resorption will be analyzed at the cutoff points –180 days and then up to 5 years after treatment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Modification of the painful sensation reported by the patient through the visual analog scale (VAS) performed in the pre-treatment and 7 after the treatment. Pain relief (painful sensation modification) will be defined as the difference in VAS scores (mm) between post-treatment pain and pre-treatment pain (median and 25-75 quartile). ;Deposition of mineralized tissue (tertiary dentin [test group - RSTC] or dentin bridge [control group - PT]) below the restorations.;Evaluation of the restoration in relation to fracture, loss of part or all restorative material and the need for repairs. | — |
