About this study

Official title: Digital Extraction and Scientific Visualization of Clinical Characteristics From 3D Data From Intraoral Scanners for Dental and Periodontal Pathologies Research : Computer Formalization and Feasibility Study

Periodontal diseases and dental pathologies are highly prevalent oral diseases. Thirty-three to fifty percent of adult population presented at least one untreated caries and more than 50% of French population are affected by severe periodontitis. These diseases affect dental organ or periodontal attached system but could have negative impact on general health, quality of life, word and individual well-being. Association between chronic diseases as diabetes, rheumatoid arthritis, cardiovascular diseases, and oral health have been well investigated. Dental and periodontal diagnosis is dependent of various clinical parameters time consuming and dependent operator. It represents a public health challenge. Informatic analysis detecting diseases could be a time gain and a more precise diagnosis tool. Today, any software or algorithm allow automatized detection, clinical qualitative or quantitative indices recording while these informations are present in numeric models

Read the detailed description

The present study explores the effectiveness of intraoral scanners in the field of dental caries and periodontal diseases diagnosis Patients presenting at least on recession are recruited without randomization. A clinical examination is performed, and a 3D impression of their mouth is obtained by intraoral scanners.

The investigators hypothesized that the 3D intra oral representations could improve oral diagnosis in patients compared to clinical examination in term of time consummation and precision. In a first time, this could be achieved by the comparison of the recession measurement obtained by a clinical measure (Ramfjord, 1959) or obtained by artificial intelligence.

The secondary objectives are :

  • To compare clinical and numerical dento-prosthetic diagram
  • To compare clinical and numerical plaque control record index (O'Leary et al., 1973)
  • To compare clinical and numerical Decayed, Missed and Filled Teeth index (Klein and Palmer, 1940)
  • To compare clinical and numerical detection of mucosal lesions

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recession measurement concordance (Ramfjord, 1959)

    Recession depths is measured between the cementum-enamel junction and the edge of the marginal gingiva.

    The clinical and numerical scored will be compared.

    Measured: Day 1

Secondary outcomes (5)
  1. Dento-prosthetic diagram concordance

    Recording the presence or absence of tooth The clinical and numerical scored will be compared.

    Measured: Day 1

  2. Plaque Control Record Concordance (O'Leary et al., 1972)

    Plaque control record will be recorded on individual tooth surfaces (mesial, distal, facial, lingual).

    PCR is calculated according the following formula :

    PCR = (Number of faces with plaque / Total number of faces) x 100

    The clinical and numerical scored will be compared.

    Measured: Day 1

  3. Gingival Index Concordance (Loe and Silness, 1963)

    Gingival index is scored as described :

    0 Normal gingival Natural coral pink gingival with no inflammation

    1. Mild inflammation Slight changes in color, slight edema. No bleeding on probing
    2. Moderate inflammation Redness, edema and glazing Bleeding under probing
    3. Severe inflammation Marked redness and edema/ulceration Tendency to bleed spontaneously

    The clinical and numerical scored will be compared.

    Measured: Day 1

  4. Decayed, Missed and Filled Teeth Index (Klein and Palmer, 1940)

    DMFT is the sum of decayed, missed due to caries and filled teech in the permanent teeth.

    Third molars are excepted.

    The clinical and numerical scored will be compared.

    Measured: Day 1

  5. Mucosal lesions detection

    Presence or absence of mucosal lesions.

    The clinical and numerical lesions will be compared.

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A study testing Numerical dental impression by intraoral scanner in people with Periodontitis and Gingivitis, run by CHU de Reims at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 12 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Julien BRAUX (03 26 78 78 24 ext. 0033, jbraux@chu-reims.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recession measurement concordance (Ramfjord, 1959) (time frame: Day 1). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2026.
