Brief Summary

Periodontal diseases are highly prevalent inflammatory diseases. These diseases are mostly due to the development and the maturation of bacterial plaque which lead to local inflammation. Individuals can develop severe attachment loss which could lead to dental loss. To prevent them, individual plaque removal procedures self-performed by the patient by tooth brushing or interdental brushes or made by professional care (scaling), are known to improve periodontal health, and thus to prevent periodontal diseases. Moreover, oral hygiene is a major factor to increase increasing the outcomes when treatments are needed. However, patients' compliance in oral health program is one of the major limits to periodontal therapeutics. In this study, the investigators evaluate the effectiveness of 3D intra-oral camera compared with conventional oral hygiene instructions, to improve oral health motivation.

Conditions

Periodontitis; Gingivitis

Outcome Measures

Primary Outcomes (1)

• Plaque Control Record Evolution

  Recording the presence of plaque on individual tooth surfaces (mesial, distal, facial, lingual). The plaque is highlighted by a periodontal probe. PCR is calculated according the following formula : PCR = (Number of faces with plaque / Total number of faces) x 100

  Day 14

Study Arms (2)

Conventional motivation procedure

ACTIVE COMPARATOR

Conventional motivation procedures defined as a presentation of the modified Bass technique on a dental teaching macro model plus intra oral instruction provided in patient's mouth with a hand mirror.

Other: No intervention

Conventional motivation procedure supported by 3D representations

EXPERIMENTAL

Conventional motivation procedures associated with 3D intra oral procedures. A 3D intra-oral modelization will added to the previously described procedure. Then, a periodontist will show the sites contaminated by dental plaque to the patient.

Other: Intra oral scan

Interventions

Intra oral scan OTHER

Cover key details of the intervention. Must be sufficiently detailed to distinguish between arms of a study and/or among similar interventions Intervention consists in an 3D intra oral representation of the oral cavity.
