Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 45 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Have at least two molars supported permanent dentition free of any clinically significant occlusal interference and require posterior restoration and fulfilled the inclusion criteria, patients will be informed about the study and will be given an informed consent.
  • The two studied materials restorations should be used in approximately the same sized lesions or within the same extensions.
  • The patient will be reimbursed for attending for the clinical evaluation(s) of their restorations.
  • Be a regular dental attender who agree to return for assessments.

Who cannot join

  • There is history of any adverse reaction to clinical materials of the type to be used in the study.
  • There was evidence of occlusal parafunction and/or pathological tooth wear.
  • Patients whose history revealed parafunctional habits or use of medications that potentially could cause hyposalivation.

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 Ahmed Amr, MDS (01224406444, drahmedamr999@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

modified United States Public Health Service criteria (USPHS) (time frame: 1 year). 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 NCT05276154, which also lists 12 linked publications.
