About this study

Official title: Comparison of Different Intracanal Medicaments on Post-operative Pain in Teeth With Symptomatic Apical Periodontitis: A Randomised Controlled Trial

Comparison of different intracanal medicaments during root canal treatment to assess their effect on post-operative pain in teeth with Symptomatic Apical Periodontitis

Read the detailed description

Pain is the most common clinical symptom associated with endodontic treatment. Symptomatic apical periodontitis (SAP) results in significant post-operative discomfort due to microbial invasion and inflammatory changes in periapical tissues. Intracanal medicaments are used to reduce microbial load and inflammation between treatment appointments, potentially reducing post-treatment pain. This study investigates the comparative effectiveness of three commonly used intracanal medicaments in reducing pain following biomechanical preparation:

Group 1: Calcium hydroxide (CH)

Group 2: Chlorhexidine gel (CHX 2%)

Group 3: Modified Triple Antibiotic Paste (TAP) - a combination of ciprofloxacin, clindamycin, and metronidazole in 1:1:1 ratio

A total of 480 participants with single-rooted teeth diagnosed with symptomatic apical periodontitis will be randomly assigned into three groups (160 in each group). Endodontic treatment will be performed by a single operator under standard protocols. No systemic analgesics or antibiotics will be prescribed. Pain assessment will be done using the Wong-Baker FACES Pain Rating Scale (0-10), and recorded at baseline (0 h), 6 h, 24 h, and 48 h after treatment.

The study aims to provide evidence on the most effective intracanal medicament to minimize post-operative pain, improving patient outcomes and guiding clinical decision-making.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Calcium Hydroxide (20%)Drug

    Also called Modified triple antibiotic paste

    A 20% calcium hydroxide paste will be placed as an intracanal medicament following root canal instrumentation. Applied using a Lentulo spiral, excess is removed, and the tooth is sealed with a glass ionomer temporary restoration.

  • Chlorhexidine Gel (2%)Drug

    Also called Calcium hyroxide

    A 2% chlorhexidine gel will be used as an intracanal medicament following canal preparation. It will be delivered with a Lentulo spiral, cleaned from the chamber, and the tooth sealed.

  • Modified Triple Antibiotic PasteDrug

    Also called Chlorhexidine

    A modified triple antibiotic paste consisting of ciprofloxacin, metronidazole, and clindamycin (1:1:1 by weight) will be placed in the canal using a Lentulo spiral. The excess paste will be removed, and the cavity will be sealed with temporary restorative material.

Study groups in NCT07123792
Study groupRoleWhat they receive
Calcium Hydroxide groupExperimentalParticipants in this group will receive 20% calcium hydroxide paste as the intracanal medicament after root canal instrumentation. The medicament will be placed using a Lentulo spiral, excess removed from the chamber, and the tooth sealed with glass ionomer cement. Pain will be assessed at 0, 6, 24, and 48 hours postoperatively.
Receives: Drug: Calcium Hydroxide (20%)
Chlorhexidine groupExperimentalParticipants in this group will receive 2% chlorhexidine gel as the intracanal medicament following canal preparation. It will be placed with a Lentulo spiral and sealed in the same manner. Postoperative pain will be evaluated at the same intervals.
Receives: Drug: Chlorhexidine Gel (2%)
Modified triple antibiotic pasteExperimentalParticipants in this group will receive a modified triple antibiotic paste made from ciprofloxacin, metronidazole, and clindamycin in a 1:1:1 ratio by weight. The paste will be placed inside the canal using a Lentulo spiral and sealed as per protocol. Pain will be recorded at 0, 6, 24, and 48 hours post-treatment.
Receives: Drug: Modified Triple Antibiotic Paste

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Post-operative Pain Intensity Measured Using the Wong-Baker FACES Pain Rating Scale (WFPRS)

    Pain intensity will be assessed using the Wong-Baker FACES Pain Rating Scale (WFPRS), a validated 6-point facial expression scale. The scale ranges from 0 (no pain) to 10 (worst pain), with corresponding facial images used to help patients subjectively rate their pain. This tool will be used during follow-up calls to determine the patient's level of pain after root canal instrumentation and medicament placement.

    Units of Measurement:

    Score range: 0-10 (intervals of 2)

    Measured: At baseline (0 hours), 6 hours, 24 hours, and 48 hours post-operatively

Questions about this trial

What is this clinical trial studying?

A study testing Calcium Hydroxide (20%), Chlorhexidine Gel (2%) and Modified Triple Antibiotic Paste in people with Periodontal Diseases, run by HITEC-Institute of Medical Sciences at 1 site in Pakistan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Aug 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Pakistan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Post-operative Pain Intensity Measured Using the Wong-Baker FACES Pain Rating Scale (WFPRS) (time frame: At baseline (0 hours), 6 hours, 24 hours, and 48 hours post-operatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07123792, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
