January 13, 2021 updated by: Seçil Çalışkan, Eskisehir Osmangazi University

The Effects of Antibiotic Combinations on Mesenchymal Stem Cells Derived From Apical Papilla

The purpose of this study was to evaluate the indirect effects of antibiotic combinations. SCAP viability, proliferation and apoptosis of the cells were evaluated. Osteocalcin (BGLAP), dentin sialo phosphoprotein (DSPP) and alkaline phosphatase (ALPP) gene expression levels were also evaluated.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 purpose of this study was to evaluate the indirect effects of triple (TAP- ciprofloxacin, metronidazole and minocycline), double (DAP- ciprofloxacin and metronidazole) and modified triple antibiotic pastes (mTAP- ciprofloxacin, metronidazole and cefaclor) on mesenchmal stem cells derived from apical papilla (SCAP). SCAP were isolated from the impacted third molar teeth of the young adults. TAP, DAP and mTAP treatment (14-day medication and 28-day medication) were applied on SCAP and viability, proliferation and apoptosis of the cells were evaluated after four weeks. Osteocalcin (BGLAP), dentin sialo phosphoprotein (DSPP) and alkaline phosphatase (ALPP) gene expression levels were also evaluated.

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.

Ages Eligible for Study

16 years to 22 years (Child, Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Tissue samples were obtained from the apex of the extracted third molar teeth of young adult patients aged between 16-22 .

Description

Inclusion Criteria:

  • Patients with open apex third molar teeth for extraction indication

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
Measurment of Cell Viability and Apoptosis
Time Frame: 1 year
To evaluate cell viability and apoptosis MuseCell Analyzer Count and Viability kit (Merck Millipore, Taufkirchen, Germany) was used according to the manufacturer's protocol.
1 year
Measurment of cell differantiation
Time Frame: 1 year
To determine gene expression levels, total RNA of SCAP was extracted using the Ambion PureLink RNA mini kit (Invitrogen, US) and the Roche cell RNA Kit (Penzberg, Germany) according to the manufacturer's instructions.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2014

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
