An interventional study of Numerical dental impression by intraoral scanner in Periodontitis, Gingivitis and Dental Caries, sponsored by CHU de Reims. Recruiting at 1 site in France. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-12.

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
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 :
1,231 studies on the registry are indexed under Periodontitis; 295 are open to participants now.
This study's planned enrollment of 30 is below the median of 44 across 846 interventional studies indexed under Periodontitis.

Other: Numerical dental impression by intraoral scanner
Intervention consists in an 3D intra oral representation of the oral cavity
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.
Time frame: Day 1
Dento-prosthetic diagram concordance
Recording the presence or absence of tooth The clinical and numerical scored will be compared.
Time frame: Day 1
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.
Time frame: Day 1
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.
Time frame: Day 1
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.
Time frame: Day 1
Mucosal lesions detection
Presence or absence of mucosal lesions. The clinical and numerical lesions will be compared.
Time frame: Day 1
