Evaluation of Zinc Oxide Eugenol and Iodoform-Calcium Hydroxide as Filling Materials in Primary Molar Root Canals Prepared by Rotary and Manual Files

Egypt44 participantsStarted 2026-02-15

Plain-language summary

This randomized controlled clinical trial aims to compare the clinical and radiographic outcomes of Zinc Oxide Eugenol (ZOE) and Iodoform-Calcium Hydroxide (Metapex) as root canal filling materials in primary molars prepared using either rotary or manual instrumentation techniques. Forty-four teeth from children aged 5-8 years indicated for pulpectomy will be randomly allocated into four equal groups based on the combination of instrumentation method and filling material. Clinical parameters-pain, mobility, and sensitivity-will be assessed using standardized scales, while radiographic outcomes, including root resorption and bone density, will be evaluated using Cone Beam Computed Tomography (CBCT) at baseline, 6 months, and 12 months. The study seeks to determine which obturation material and canal preparation technique yield superior healing, adaptation, and resorption compatible with the physiological process of primary tooth exfoliation. Findings are expected to inform evidence-based selection of endodontic materials and instrumentation methods in pediatric dentistry.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
