  • assess gum health and oral hygiene
  • register decays, filled and missing teeth.

Treatment and study plan

collection of saliva, gum fluid and/or dental plaque samples

Other

Non-invasive sampling of dental plaque, crevicular fluid and/or saliva, using an examination probe, paper tips and saliva swabs

Primary outcomes

  1. 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)

Secondary outcomes

  1. 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)

  2. 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

  3. 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

  4. 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

  5. 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
