What participants receive

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

  • Olinano sealOther

    The OliNANO seal is "varnish-like" shield which is based on nanotechnology that allows an optimum adhesion to enamel and dentin, it could be used as an effective desensitizing agent by forming a protective layer that occludes the dentinal tubules which can be effective for a year as mentioned by the manufacturer. Polymeric nano calcium fluoride varnish consists of four main components, silicone polymer, NANO-fluorapatite, nano-calcium fluoride and amine fluoride (Olaflur)

  • Diode LaserDevice

    increase in the metabolic activity of odontoblasts. Thus, obliteration of the dentinal tubules and formation of tertiary dentin.

  • Olinano seal and Diode LaserOther

    Combined methods have been also evaluated in some previous studies. It showed more effect in reducing Dentin hypersensitivity than using every treatment solely

What is being measured

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

  1. Pain severity

    The pain will be assessed using the (VAS) scale. The VAS is a scale that allows the patient to self-assess the pain felt by means of a line in which the patient marks the pain level "no pain" to the "maximum pain". 0: low pain, 1 - 3: moderate pain: 4 - 6, intense pain: 7 - 9, extremely intense pain: 10

    Measured: Before the treatment (Baseline), after the first session (T1), second session (T2) will be done after a week from the first session, after 3 months (T3), 6 months (T6), 9 months (T9) and 12 months (T12)

Questions about this trial

What is this clinical trial studying?

A study testing Olinano seal, Diode Laser and Olinano seal and Diode Laser in people with Dentin Hypersensitivity, Non-carious Cervical Lesions and Gingival Recession Localized Moderate, run by Faculty of Dental Medicine for Girls 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 7 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 18 Sep 2026. 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.

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 severity (time frame: Before the treatment (Baseline), after the first session (T1), second session (T2) will be done after a week from the first session, after 3 months (T3), 6 months (T6), 9 months (T9) and 12 months (T12)). 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 18 Sep 2026.
