Single Gene Polymorphisms Associated With Molar-Incisor Hypomineralization

December 12, 2023 updated by: Marmara University

Investigation of Single Gene Polymorphisms Associated With Molar-Incisor Hypomineralization

The genetic factors associated with Molar-Incisor Hypomineralization (MIH), a dental condition affecting permanent molars in individuals aged 8-13. Buccal swab samples collected from 90 MIH-affected participants and 90 systemically healthy controls. The goal is to identify potential genetic markers contributing to the etiology of MIH, shedding light on previously unexplored aspects of genetic susceptibility.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The aim of study is to elucidate the unknown aspects of genetic predisposition that may be effective in the etiology of Molar-Incisor Hypomineralization (MIH), that is, to identify unexplored genes that may be associated with MIH. The buccal swab method will be used for the purpose of collecting DNA samples.Samples will be collected from the inner cheek using a swab. The collected samples will be placed in single-use sterile Eppendorf tubes containing Phosphate Buffered Saline (PBS) solution. The samples will be stored at +4 degrees Celsius in a refrigerator, and DNA isolations will be performed within a few days. .

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
120

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
MIH-affected participants (study group )
The Study Arm comprises individuals aged 8-13 with Molar-Incisor Hypomineralization (MIH) in at least one permanent molar.
Diagnostic test: DNA Sample Collection + DNA genotyping
Volunteers' oral epithelial cell DNA will be collected using DNA swabs, followed by DNA isolation with the PureLink DNA Isolation Kit. The isolated DNA's quality will be assessed using the Invitrogen QUBIT 4 Fluorometer, and the samples will be stored at -20°C until analysis of specific genetic regions.
Systemically healthy controls (control group )
Systemically healthy individuals without MIH.
Diagnostic test: DNA Sample Collection + DNA genotyping
Volunteers' oral epithelial cell DNA will be collected using DNA swabs, followed by DNA isolation with the PureLink DNA Isolation Kit. The isolated DNA's quality will be assessed using the Invitrogen QUBIT 4 Fluorometer, and the samples will be stored at -20°C until analysis of specific genetic regions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
genotyping of polymorphisms
Time Frame: 1.5 -2 year
The genotyping of polymorphisms will be conducted using the StepOnePlus instrument (Thermo Fisher Scientific, Inc.) through Real-Time PCR, following the manufacturers' protocols (cat. no. 4371355, Thermo Fisher Scientific, Inc.) and utilizing Taqman SNP genotyping kits. The reaction volume will be 10 µl in total, comprising 5 µl of Genotyping Master Mix (Applied Biosystems, Foster City, CA), 3.5 µl of nuclease-free H2O (Thermofisher, USA), 0.5 µl of genotyping assay (Applied Biosystems), and 1 µl of DNA.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
