What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
SylcCombination product
Also called Sylc bioactive glass
a dry powder (calcium sodium phosphosilicate), based on NovaMin powder. Bottle of small and coarse particles will be used for the treatment
fluoride varnish (Bifluorid 10)Combination product
Also called Bifluorid 10
It is a rapid- drying suspension of equal amounts of sodium fluoride and calcium fluoride.
| Study group | Role | What they receive |
|---|---|---|
| sylc bioactive glass | Experimental | Sylc is a dry powder (calcium sodium phosphosilicate), based on NovaMin powder. Bottle of small and coarse particles will be used for the treatment.
Steps:
1. Isolation: D.M. will make proper isolation for the teeth using cotton rolls.
2. Hand piece: NSK Prophymate Neo will be used to deliver the powder particles on the sensitive areas. Air stream adjusted at 40-46 psi.
3. Application: The hand piece will be held at constant distance (3-4mm) away from the tooth surface, with 60-80 degrees on the buccal surfaces. The powder will be applied for 5-10 seconds per tooth in a circular movement.
4. Suction: High volume suction will be used on lingual side of the teeth to suck any particles, and avoid patient from swallowing it. Receives: Combination Product: Sylc |
| fluoride varnish (Bifluorid 10) | Active comparator | fluoride varnish Bifluorid 10(by VOCO) will be used. It is a rapid- drying suspension of equal amounts of sodium fluoride and calcium fluoride.
The single dose form will be used, to make sure the amount of fluoride varnish used is standardized.
Steps:
1. Preparation: The tooth will be properly cleaned, and the surface will be air-dried.
2. Dispensing: The foil will be pierced using a micro- tim, the opening will be enlarged, the brush will be wet in a circular movement.
3. Application: Thin coat will be applied on the tooth surface. The varnish will be left from 10-20 seconds then air dried.
Concerning the storage of the Bifluoride 10, it will be stored in refrigerator at the operative clinic to avoid exposure to high temperature or sunlight. Receives: Combination Product: fluoride varnish (Bifluorid 10) |

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Sylc and fluoride varnish (Bifluorid 10) in people with Hypersensitivity Dentin and Tooth Hypersensitivity, run by Cairo University at 1 site in Egypt.
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 5 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 31 Jan 2019. 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 Egypt. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Pain due to dentin hypersensitivity (evaporative stimulus) (time frame: 2 minutes after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 31 Jan 2019; AzTrials last refreshed its copy on 8 Nov 2026.
