Study summary

This study is aimed to evaluate the efficacy of valacyclovir in reducing postoperative pain following emergency chamber opening for acute apical abscess .

There will be 82 participants, (41 in each group) Group A will receive Valacyclovir Group B will receive standard treatment i.e. Naproxen Sodium. Pain level will be assessed by using Numeric rating scale for 6 days

Read the detailed description

BACKGROUND:

Acute apical abscess is an inflammatory reaction to pulpal infection and necrosis characterized by rapid onset, spontaneous pain, extreme tenderness of the tooth.. Recently, it has been hypothesized that Herpesvirus infection can contribute to the pathogenesis of apical periodontitis. In symptomatic forms of apical periodontitis, the etiology can be same as it is for marginal periodontitis.

OBJECTIVE:

The aim of this study is to test the valacyclovir treatment on patients with acute apical abscess, as it might help reducing pain and the need for analgesics

METHODOLOGY:

The study will be conducted by the principal investigator, a co-investigator, and a research assistant. Patients will be recruited in the study from the Operative Dentistry outpatient department, Dr. Ishrat ul Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences. The study includes 82 patients, who will be equally divided into two groups. Group A would be Valacyclovir Group (41 patients) and Group B Control Group (41 patients). All patients must have pulp necrosis and acute apical abscess. Patients should have moderate to severe pain according to NRS-11 pain assessment scale. It measures the pain extremes between 0-10 (0=no pain while 10= extreme pain). Patients with moderate to severe pain levels i.e., >4 NRS will be the candidate for this study. All patients will be consented, educated and calibrated on numeric rating scale of pain. All the potential candidates will be given emergency treatment by performing chamber opening and pulpectomy. After performing initial treatment patients in valacyclovir group will be advised to take valacyclovir (2g immediate dose followed by 500mg 2 times daily for 3 days) along with the analgesic (SOS, if needed). The control will be prescribed with analgesic, Naproxen Sodium550mg for 3 days (if needed). Baseline for the study would be day 1 (start of medication). A research assistant will phone the study participants daily till 6 days to evaluate pain according to numeric rating scale and analgesic used.

On the first day, patient will be examined. If the patient fulfils inclusion criteria, he or she will be provided with the emergency chamber opening and pulpectomy. Half patients will be given prescription of valacyclovir (2g immediate dose followed by 500mg 2 times daily for 3 days) along with the analgesic (SOS, if needed). The other half will be control group and prescribed with analgesic (SOS, if needed) only. A research assistant will phone the study patients at a preset time daily for 6 days to evaluate,

  1. Pain level according to numeric rating scale (NRS)
  2. Analgesic used Difference in pain relief between valacyclovir and control group will be measured and daily consumption of analgesics will be evaluated at the end of 6-day study

STATISTICAL ANALYSIS:

The statistician will analyze the data by applying Mann Whitney test which will assess the daily difference in pain levels and intake of analgesics between the valacyclovir group and control group. The Friedman test will be applied to analyze the differences in repeated measures between the valacyclovir and control group.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 10, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
