About this study

Official title: Evaluation of Clinical Performance for Recently Introduced Non Coated Glass Ionomer in Occlusal Caries in Posterior Teeth Compared to Conventional Glass Ionomer With Coating: A Randomized Clinical Trial

In patients with occlusal caries in posterior teeth, does the use of recently introduced non coated glass ionomer provide better clinical performance compared to conventional glass ionomer with surface coating?

-Primary objective: To evaluate clinical performance of different types of restorations (Ketac molar with coating and Ketac Universal Aplicap 3M without coating) in occlusal caries in posterior teeth.

Read the detailed description

The study will be conducted in Conservative Dentistry Department, Faculty of Dentistry, Cairo University; The operator in charge will be Mahmoud Magdy Eldamanhory

Patients will be selected from the outpatient clinic of the department Conservative Dentistry Department, Faculty of Dentistry, Cairo University

  • Local anesthesia will be applied to patients complaining about pain or sensitivity to prevent discomfort during restorative procedures.
  • Conservative cavity design will be used according to the principals of minimal invasive dentistry.
  • All the cavities will be performed by the main author using #57 straight plain carbide fissure bur held in high speed contra-angled hand piece with water cooling system.
  • All internal line angles will be slightly rounded.
  • Each bur will be discarded after 5 preparations
  • If deep caries will be found, it will be removed with large round bur at low speed and a thin layer of calcium hydroxide will be placed on the deep portion of the cavity.
  • Isolation will be maintained by using Rubber Dam.
  • The dentin and enamel of cavities will be conditioned with 20% polyacrylic acid for 20 seconds (Cavity Conditioner, GC), washed, and briefly dried.
  • The restorations will inject into the cavity.
  • After the passage of the manufacturer's recommended setting time of 2.5 minutes, the restoration will be trimmed and polished wet using high-speed fine diamonds.

In control group ketac molar with coating:

-After the restoration will briefly dry, Ketac Coat will be applied and photocured for 20 seconds using a photo-curing light.

In study group " Ketac Universal Aplicap 3M without coating":

-The newest addition to glass ionomer family, Ketac Universal Aplicap glass ionomer restorative is a self-cure, one-step placement material designed to help to finish faster. There's no need for conditioning, coating or light-curing steps.

What participants receive

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

  • Non Coated Glass IonomerCombination product

    Also called Ketac Universal Aplicap- Glass Ionomer Restorative

    KetacTM Universal AplicapTM Glass Ionomer Restorative saves time by eliminating the need for a coating-yet still delivers the compressive strength and surface hardness that are higher than several competitive glass ionomers which require one.

  • Conventional Glass Ionomer with CoatCombination product

    Conventional Glass Ionomer with Coat

Study groupRoleWhat they receive
Non Coated Glass IonomerExperimentalA faster, easier procedure is great, but you want assurance that reducing chair time doesn't mean compromising on performance. KetacTM Universal AplicapTM Glass Ionomer Restorative saves time by eliminating the need for a coating-yet still delivers the compressive strength and surface hardness that are higher than several competitive glass ionomers which require one.This advancement is the latest in 3M's 30-year history of developing proven and trusted glass ionomers.
Receives: Combination Product: Non Coated Glass Ionomer
Conventional Glass Ionomer with CoatActive comparatorA bulk-fill, packable and fast-setting conventional glass ionomer. Because it's less "technique sensitive" than a composite it's ideal for difficult-to-isolate posterior restoration. High compressive strength and marginal integrity make it a glass ionomer of choice for posterior restorations.Ketac Conditioner Dentin Pretreatment is required; Ketac Glaze Light-Cured Varnish applied on the top of the restoration to avoid moisture contamination.
Receives: Combination Product: Conventional Glass Ionomer with Coat

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Non Coated Glass Ionomer and Conventional Glass Ionomer with Coat in people with Occlusal Caries, 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 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 26 Mar 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 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?

Distance penetrated by the Explorer at the tooth restoration interface (time frame: during procedure). The study lists 28 primary outcomes in all. 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 26 Mar 2025.
