Official title: Evaluation of Glass Ionomer With Advanced Glass Hybrid Technology Versus Resin Modified Glass Ionomer in Adult Patients With Carious Cervical Lesions After One Year: Randomized Clinical Trial

The main question it aims to answer are:
- Will the use of glass ionomer with advanced glass hybrid technology, achieved through introduction of ultra-fine highly reactive glass and high-molecular weight polyacrylic acid powders within conventional glass ,or Resin Modified Glass Ionomer have better mechanical and estheic properties over one year in adult patients with cervical carious lesions ?
Participants will be assessed for medical and dental histories first. Then an examination of the patients will be done using visual inspection by using a dental mirror and probe. Eligible patients according to inclusion and exclusion criteria will be informed about all procedures with follow up time if they accept, their signature on written informed consents will be obtained. Eligible participants will be randomly divided into two groups according to the type of restoration that will be received after class V cavity preparations for carious cervical lesions.
Patients will be given local anaesthesia (Mepecaine - L Cartridges) as required, and the teeth will be isolated. A No. #330 bur (MANI, INC, Japan) in a high-speed hand piece with air/water coolant will be used to prepare class V cavity. Sharp excavators of suitable size were used to excavate soft carious lesions in dentin. the prepared cavity will be isolated with rubber dam.
The first group (A) will be received resin modified glass ionomer restorative material and the second group (B) will be received advanced glass hybrid glass ionomer . Each restoration will be evaluated for clinical parameters after finishing and polishing at baseline and regular recalls of 6 months and one year. The restorations will be clinically examined according to FDI criteria criteria in terms of esthetic and mechanical properties . The information that will be obtained will be collected and statistically analyzed.

Questions about this trial
What is this clinical trial studying?
A study testing Glass Ionomer with Advanced Glass Hybrid Technology (Equia forte HT fil, GC, Japan) in people with Dental Caries Class v, run by Cairo University.
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 12 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: status not confirmed, as of the sponsor's last update on 15 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact zayed (00201012561397, aya_magdy@dentistry.cu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
FDI criteria (time frame: one year). 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 15 Nov 2022; AzTrials last refreshed its copy on 8 Nov 2026.
