Primary Outcome Measures:
  • Area Under the Curve (AUC) of the Pain Scores. [ Time Frame: Pain scores will be measured over the time from end of surgery (time 0) to the 6 hour post-surgery ]
    Pain will be scored by the patient at the end of surgery (time 0) and at 15-minute intervals after surgery for a total of 6 hours on a 0-100 mm VAS (from 0 = no pain to 100 = worst pain imaginable).


Secondary Outcome Measures:
  • Postsurgical Extra-oral Swelling [ Time Frame: measured at 6 hours postsurgery, at day 3 and 1 week postsurgery ]
  • Trismus [ Time Frame: measured at 6 hours postsurgery, at day 3 and 1 week postsurgery ]
  • Peak Pain Intensity [ Time Frame: measured from end of surgery up to 12 hours postsurgery ]
  • Time to First Use of Rescue Medication. [ Time Frame: measured from end of surgery up to 1 week postsurgery ]
  • Amount of Rescue Medication [ Time Frame: consumed by the patient every 15-minutes postsurgery up to 6 hours postsurgery ]
  • Rescue Medication Consumption [ Time Frame: consumed by the patient from end of surgery up to 24 and up to 48 hours postsurgery ]
  • Patient and Investigator Global Evaluation of the Effectiveness of Treatment [ Time Frame: at 6 hour postsurgery and on Day 3 ]
  • Time to Onset of Pain [ Time Frame: measured from end of surgery up to 12 hours postsurgery ]
  • Wound Healing [ Time Frame: at 6 hour postsurgery, and on day 3 and 1 week postsurgery ]
  • Recurrent Bleeding [ Time Frame: every hour up to 6 hour postsurgery ]
  • Vital Signs [ Time Frame: presurgery (within 30 days from surgery), at day of surgery (day 1), day 3 and 1 week postsurgery. ]
  • Number of Patients With Adverse Events [ Time Frame: from signature of the informed consent to 1 week postsurgery ]
