Role of NLRP3 in Periodontitis and Diabetes

January 23, 2021 updated by: Gaetano Isola, DDS, PhD, University of Messina

Evaluation of Serum and Salivary NLRP3 in Periodontitis and Diabetes Patients

NLRP3 plays a key role in endothelial function and may be a link for the known interaction of periodontitis and diabetes. The investigators compared the impact of gingival health, periodontitis (CP), diabetes or of both diseases (CP +diabetes) on saliva and serum NLRP3levels.

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 aim of this study was to evaluate a possible association between NLRP3 and gingival health, periodontitis (CP), diabetes or of both diseases (CP +diabetes) on saliva and serum NLRP3 levels.

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

35 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

healthy controls (n=32), periodontitis (n=34), diabetes (n=33), and a combination of periodontitis + diabetes (n=34)

Description

Inclusion Criteria:

  • Presence of at least 15 teeth

  • CP with a minimum of 40% of sites with a clinical attachment level (CAL)

    ≥2mm and probing depth (PD) ≥4mm;

  • Presence of at least ≥2 mm of crestal alveolar bone loss verified on digital periapical radiographs
  • Presence of ≥40% sites with bleeding on probing (BOP)

Exclusion Criteria:

  • Intake of contraceptives
  • Intake of immunosuppressive or anti-inflammatory drugs throughout the last three months prior to the study
  • Status of pregnancy or lactation
  • Previous history of excessive drinking
  • Allergy to local anaesthetic
  • Intake of drugs that may potentially determine gingival hyperplasia such as Hydantoin, Nifedipine, Cyclosporin A or similar drugs.

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.

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.
June 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.
September 18, 2017

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.
