Oral Microbiota and Oral Status of Adult Patients With Autism Spectrum Disorders (MICAA: MICrobiota Autism Adults) (MICAA)

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: Completed
• Conditions: Autism Spectrum Disorder

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

Participant Group / Arm	Intervention / Treatment
Experimental: Adults with Autism Spectrum Disorder; Adults with autism spectrum disorder; Aged between 18 and 60 years old; Dental cares and follow-up in Nancy hospital	Other: collection of saliva, gum fluid and/or dental plaque samples; Non-invasive sampling of dental plaque, crevicular fluid and/or saliva, using an examination probe, paper tips and saliva swabs

What is the study measuring?

Primary Outcome Measures

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

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Assessment of the presence of parasites Entamoeba gingivalis subtype 1 (ST1) and subtype 2 (ST2) and Trichomonas tenax	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	Index used = the Dutch Periodontal Index 0 = minimum value, better outcome 4 = maximum value, worse outcome	Day 1
Assessment of the dental condition	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	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	Data collection via a form fulfilled by the participant or the patient's legal guardian	Before samples collection and clinical examination
