Trial Title: Effects of Transcranial Direct Current Stimulation (tDCS) on Patients With Chronic Orofacial Pain

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Male and female between 18 and 75 years old~* Clinic history of previous orofacial and/or dental surgery~* Chronic orofacial pain for more than a year measurable by the VAS more than 3 .~* Pain not responsive to pharmacological treatment (analgesic, anti inflammatory, opiates, antidepressant drugs and physiotherapy modalities)~Exclusion Criteria:~* Contraindication to tDCS: presence of metallic implants that can be stimulated, moved or overheated by electric current, positive anamnesis for epilepsy, implantable systems ( ventriculoperitoneal shunt, pacemaker, intracranial pumps, intracranial metallic systems)~* Major neurological or psychiatric pathologies~* Pregnancy~* Severe hepatorenal and cardiopulmonary diseases

Study Arms:
- sham tDCS (Type: ACTIVE_COMPARATOR): This group will receive sham-tDCS for 5 days. The anode will be placed on the primary motor cortex (M1) of the dominant hemisphere and the cathode on the contralateral supraorbital area. The direct current is transmitted through a pair of sponge electrodes, with a surface of 35 cm2 (7x5), soaked in saline solution and, it is generated by a constant current stimulator, with rechargeable batteries. This continuous stimulation lasted 30 seconds, with an intensity of 1 milliampere.
- real tDCS (Type: EXPERIMENTAL): This group will receive continuous stimulation lasting 20 minutes daily, for 5 days.~Transcranial direct current stimulation (tDCS) will be administered as follows. The anode will be placed on the primary motor cortex (M1) of the dominant hemisphere and the cathode on the contralateral supraorbital area. The direct current is transmitted through a pair of sponge electrodes, with a surface of 35 cm2 (7x5), soaked in saline solution and, it is generated by a constant current stimulator, with rechargeable batteries. This continuous stimulation lasted 20 minutes, with an intensity of 1 milliampere.

Based on this trial design, predict the completion outcome and termination type (if applicable).
