About this trial
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

Trial outcomes
Primary outcomes
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.
Time frame
Day 1Secondary outcomes
1
Dento-prosthetic diagram concordance
Recording the presence or absence of tooth The clinical and numerical scored will be compared.
Time frame
Day 12
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 13
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 14
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.
