About this study
Official title: Effect of Calcium Fluoride Nanoparticles in Prevention of Demineralization During Orthodontic Fixed Appliance Treatment: a Randomized Clinical Trial
The aim of this study is to evaluate the effectiveness of calcium fluoride nanoparticles containing orthodontic primer in preventing or decreasing the incidence WSLs over a period of 6 months in patients with fixed orthodontic appliances.
This study proposed to be double blinded, split mouth, randomized clinical trial, with equal randomization (1:1 allocation ratio).
Read the detailed description
The sample was selected and recruited from patients attending two centres (Orthodontic Department at Karbala Governmental Specialized Dental Center and Almina Dental Private Clinics/Karbala), but the bonding and follow up sessions were done in Almina Dental Private Clinics/Karbala. Patient recruitment was done according to specified inclusion and exclusion criteria.
Intervention procedure planned to be by bonding fixed orthodontic appliances to all patients. The four quadrants of the mouth will be divided into two groups (Group 1 and 2), with one group, the upper right and lower left quadrants bonded with nCaF2 resin, while the upper left and lower right quadrants bonded with control resin. For the other group, the reverse will be carried out. Then, by the use of a computer random number generator, the two groups will be randomly allocated, and each number in the random table will be given a study number in order to create the final Allocation Table for the participants in the study (which contained the study number and allocation group). the primary planned to be measured by DIAGNOdent Pen 2190 device to measure enamel demineralization objectively, while the secondary objective planned to be quantitative detection of Streptococcus mutans bacteria by using real-time PCR

nCaF2 primerDrug
Also called Orthodontic primer containing calcium fluoride nanoparticles
Calcium fluoride nanoparticles was added to conventional orthodontic primers to develop bioactive primer. This primer was examined previously for its biological and physical properties
Control primerDrug
Also called TransbondTM XT orthodontic primer
Conventional orthodontic primer
| Study group | Role | What they receive |
|---|---|---|
| orthodontic primer containing calcium fluoride nanoparticles | Active comparator | Fixed appliance for ten maxillary teeth and the contralateral mandibular teeth will be bonded using orthodontic primer containing calcium fluoride nanoparticles Receives: Drug: nCaF2 primer |
| Control primer | Placebo comparator | Fixed appliance for ten maxillary teeth (contralateral to experimental ten side)and the contralateral mandibular teeth will be bonded using conventional primer (TransbondTM XT orthodontic primers (3M-Unitek, Monrovia, USA) Receives: Drug: Control primer |
What is being measured
The primary outcome is the main question the study is designed to answer.
DIAGNOdent Pen scores change
assessing changes in the amount of enamel demineralization (DIAGNOdent Pen scores) between four time points:-
- baseline (before brackets bonding)
- after one month of brackets bonding
- after three months of brackets bonding
- after six months of brackets bonding
Measured: Six months
Secondary outcomes (1)
Streptococcus mutans load change
Quantitative detection of streptococcus mutans load changes (using real time PCR) between four time points:-
- baseline (before brackets bonding)
- after one month of brackets bonding
- after three months of brackets bonding
- after six months of brackets bonding
Measured: Six months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing nCaF2 primer in people with White Spot Lesion of Tooth, run by University of Baghdad at 1 site in Iraq.
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 4 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 6 Aug 2021. 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 Iraq. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Rawof R. Al Tuma, MSc (+9647901762894, raooftoma@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
DIAGNOdent Pen scores change (time frame: Six months). 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 NCT04994314, 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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Aug 2021; AzTrials last refreshed its copy on 7 Nov 2026.
