Characterisation of the Oral Microbiota and Oral Status of a Population of Adult Patients With Autism Spectrum Disorders: a Pilot Study

The goals of this pilot study are to assess the presence of harmful germs for gums and to assess oral health in adults with autism spectrum disorder.

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

Participants or their tutors will fulfill a form with general health information and daily habits.

Investigators will :

  • collect saliva, gum fluid and/ or dental plaque to characterise germs
  • assess gum health and oral hygiene
  • register decays, filled and missing teeth.

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.
Interventional

Enrollment (Actual)

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.
37

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.

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

  • Adult

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
Presence of periodontopathogenic bacteria (harmful for gums)
Time Frame: Collection on Day 1
Technique used = Polymerase Chain Reaction (PCR) Measure unit = Colony-Forming Unit (CFU)
Collection on Day 1

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Assessment of the presence of parasites Entamoeba gingivalis subtype 1 (ST1) and subtype 2 (ST2) and Trichomonas tenax
Time Frame: Collection on Day 1
Technique = Polymerase Chain Reaction (PCR) Unit = Colony-Forming Unit (CFU)
Collection on Day 1
Assessment of the periodontal status of patients with Autism Spectrum Disorder
Time Frame: Day 1
Index used = the Dutch Periodontal Index 0 = minimum value, better outcome 4 = maximum value, worse outcome
Day 1
Assessment of the dental condition
Time Frame: Day 1
Dental data will be collected using the Decay-Missing-Filled/Teeth (DMFT) score 0 = minimum value, best outcome 28 = maximum value, worst outcome
Day 1
Assessment of oral hygiene
Time Frame: Day 1
Oral hygiene will be assessed using the Silness and Löe plaque index and the lifestyle questionnaire 0 = minimum value, best outcome 3 = maximum value, worst outcome
Day 1
Collection of data about lifestyle habits (oral and dental hygiene, diet, activity, etc.) and drug treatments that may influence the clinical parameters observed
Time Frame: Before samples collection and clinical examination
Data collection via a form fulfilled by the participant or the patient's legal guardian
Before samples collection and clinical examination
