NCT02457325

Brief Summary

The present clinical trial randomized compared the clinical efficacy of the local anesthetics articaine in two concentrations, 2% and 4%, in association with 1:200,000 adrenaline, for the removal of lower third molars. Onset, duration of postoperative analgesia, duration of anesthetic action on soft tissues, intraoperative bleeding, hemodynamic parameters, postoperative mouth opening and wound healing at the 7th postoperative day were evaluated. For this purpose, 50 healthy volunteers underwent removal of symmetrically positioned lower third molars, in two separate appointments (one to two months apart), under local anesthesia with either articaine 2% or 4% (both with 1:200,000 adrenaline) in a double-blind, randomized and crossed manner.

Outcome Measures

Primary Outcomes (6)

  • Onset of Anesthetic

    Onset of anesthetic agent action, as determined by the loss of sensibility of the inferior lip, the corresponding half of the tongue, and the mucosa as reported by the patient.

    During the surgical procedure, an average of 30 minutes

  • Quality of Anesthesia

    Quality of anesthesia during surgery based on a category 3-point scale: 1) the patient reported no discomfort; 2) the patient reported discomfort, without the need to supplement the anesthesia; 3) reported some discomfort by the patient, requiring anesthesia complementation. Intraoral bleeding that will be evaluated by the surgeon according to a 3-point scale (1: minimal, 2: normal and 3: Maximum), immediately after the following steps: injection of the first cartridge anesthesia, incision, mucoperiosteal detachment, osteotomies, tooth section, extraction, cleaning and suturing.

    During the surgical procedure, an average of 30 minutes

  • Intraoperative Bleeding

    Intraoperative bleeding, rated by the surgeon according to a 3-point category rating scale (1-minimal bleeding; 2-normal bleeding; 3-excessive bleeding) (SISK, 1986), immediately after the following steps: injection of the first cartridge of articaine, tissue incision, flap reflection, bone removal (when this procedure was necessary), tooth extraction, cleaning of the operated site, and completion of suturing.

    During the surgical procedure, an average of 30 minutes

  • Blood Pressure

    mean blood pressure was verified and recorded at surgical moments previously described (injection of the first cartridge anesthesia, incision, mucoperiosteal detachment, osteotomies, tooth section, extraction, cleaning and suturing), carried out with the aid of a system for monitoring hemodynamic parameters.

    During the surgical procedure, an average of 30 minutes

  • Heart Rate

    Heart rate to be verified and recorded surgical at moments described above, carried out with the aid of a system for monitoring hemodynamic parameters.

    During the surgical procedure, an average of 30 minutes

  • Oxygen Saturation

    Oxygen saturation to be verified and recorded at surgical moments described above, carried out with the aid of a system for monitoring hemodynamic parameters.

    During the surgical procedure, an average of 30 minutes

Secondary Outcomes (5)

  • Duration of Post-operative Analgesia

    During the day of the surgery, 24 hours

  • Postoperative Mouth Opening

    Seventh postoperative days

  • Wound Healing of the Operated Area

    Seventh postoperative day

  • Evaluation of Post-surgical Pain

    Seventh postoperative day

  • Postoperative Anesthesia

    During the day of the surgery
