About this study

Official title: Association Between Enamel Gene Variants and Dental Caries in Adults

VDR and TFIP11 Gene polymorphism and gene-environment interactions on caries etiology and susceptibility in adults.

Read the detailed description

To date, genes can be grouped into categories based on the factor influencing dental caries. The major candidate gene categories to date include enamel formation genes, immune response genes, genes related to saliva, and genes related to taste and dietary habits.

TFIP11 and VDR genes are related to enamel formation genes

Being tested

What participants receive

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

  • high caries experienceGenetic

    Also called DNA isolation, genotyping

    DNAs were obtained from epithelial cells in buccal mucosa and were extracted with Genomic DNA Isolation Kit

Study groups in NCT04124718
Study groupRoleWhat they receive
high caries experience80 adults will be allowed in the high caries experience group according to DMFT index DMFT>13.9
Receives: Genetic: high caries experience
low caries experience80 adults will be allowed in the high caries experience group according toDMFT index DMFT≤4
Receives: Genetic: high caries experience

What is being measured

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

  1. past caries experience

    Each tooth will be examined and recorded as decayed, missing, or filled

    Measured: 3 weeks

Secondary outcomes (1)
  1. Plaque index

    The plaque amount is scored by using Silness\&Löe Plaque Index plaque index PI<1.0 healthy PI 1.1-2.0 mild PI>2 high plaque

    Measured: 3 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Low Caries Experience and High Caries Experience, run by Recep Tayyip Erdogan University Training and Research Hospital at 1 site in Turkey (Türkiye).

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 2 inclusion and 3 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 15 Apr 2021. 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 Turkey (Türkiye). 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?

past caries experience (time frame: 3 weeks). 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 NCT04124718, which also lists 1 linked publication.

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 Apr 2021.
