Brief summary: Oraverse © (Phentolamine mesylate) is a product designed to reverse the effect of local anesthetics used in dentistry. Its main objective is to reduce the postoperative period during which the patient suffers from the lack of sensitivity in the perioral soft tissues, it is an obvious discomfort, a difficulty to speak or eat, and sometimes a risk of self-injury in the lips and / or tongue .

Detailed description: PURPOSE OF THE STUDY:

To analyze the response of Oraverse in patients receiving complete oral disinfection treatment, after administration of Lidocaine 2% 1/80000, Articaine 4% 1/200000 or Bupivacaine 0,5% 1:200000 in mandible, in comparison with the contralateral control side.

Eligibility criteria: Inclusion Criteria:

* Previously diagnosticated to receive dental treatment according to Leonformacion's criteria

* Patients with known allergies to anesthetics, excipients or phentolamine mesylate
* Patients with previous facial paresthesia
* Patients who had taken any painkiller or anti-inflammatory the day before
* Patients in which the anesthetic technique fails or has to be reinforced with more than two carpules
