Summary

The Virus in Endodontics (VE) phase I pilot study for preoperative pain will be analyzed and adjusted for the Phase II clinical trial. The Phase II clinical trial on preoperative pain, postoperative pain, and clinical healing will involve 250 patients. Patients will be recruited from the same pool of participants as the Phase II clinical trial. Preoperative cone beam computed tomography (CBCT) scans will be taken as well as three and six month postoperative CBCT scans. The secondary outcomes form the Phase II randomized clinical trial will be clinical success and visible radiographic healing determined by CBCT images.

Conditions

  • Acute Apical Abscess
  • Pain, Acute

Interventions

DRUG

Valacyclovir 500 MG

Consistent with the pilot study VEII will use a random number generator to randomly assign a Manila packet containing amoxicillin 500mg + Valtrex (valacyclovir 500mg x three times daily for 7 days). Opaque medication packaging and using standardized verbal and written instructions helps ensure blindness of the VEII calibrated clinician, and patients of the therapeutic group they were assigned to.

DRUG

Placebo

Consistent with the pilot study VEII will use a random number generator to randomly assign a Manila packet containing amoxicillin 500mg + Placebo (empty capsule). Opaque medication packaging and using standardized verbal and written instructions helps ensure blindness of the VEII calibrated clinician, and patients of the therapeutic group they were assigned to.
