简要总结
Orthodontic appliances have been shown to interfere with oral hygiene maneuvers by providing many additional sites for formation and retention of biofilm.
Its accumulation is responsible for undesirable effects such as decays and periodontal pathologies. These lower the benefit / risk ratio of orthodontic treatments. In addition, their management is not negligible at the macroeconomic level.
As such, it is more than necessary for the orthodontist to teach oral hygiene methods adapted to each of his patients fitted to limit the risk of appearance of biofilm.
详细描述
Patients applying for orthodontic treatment with braces in the orthodontic unit of the Rennes dental center will be offered to participate in the study. For each patient, the inclusion and non-inclusion criteria will be checked, and consent and a document explaining the course of the study will be delivered to them personally. The duration of the study will be 6 months for each of them. Each will be randomized to one of three study groups. Throughout the study, patients in groups 1 and 2 will have to make 5 appointments. Group 3 patients must honor 6 appointments.
Patients in group 1 (control group) will receive oral hygiene advice given orally in the chair during the bonding appointment and at each check-up appointment. Patients in group 2 will receive these same oral advice, associated with a demonstration of brushing methods in the sink with active participation (use of plate developer and then the Oral B electric toothbrush with special orthodontic head) during the bonding appointment as well than at each check-up appointment. Patients in group 3 will receive the same treatment as those in group 1 but will have an additional appointment between the device bonding appointment and the first check-up. This is a 15-minute session dedicated to teaching oral hygiene. This session will include watching of an educational video followed by a quiz, as well as the application of the methods taught in the sink (using plate developer and the Oral B electric toothbrush with special orthodontic head).
At the end of the appliance bonding appointment (first appointment) each patient (from each group) will leave with a hygiene kit including an electric toothbrush with two orthodontic heads, an Oral B toothpaste, from orthodontic wax and the analgesic prescription conventionally performed when installing a device.
The plaque index readings, i.e. the taking of 3 macrophotographic shots (with reflex camera, allowing the MOP plaque index to be assessed in a second step), and the clinical index of gingival inflammation will be performed at each appointment (except during the dedicated session of group 3) by an examiner who will be blind from the group belonging to each patient.
Exception made for the day of bonding, during which the plate index reading will be made just before the placement of the multi fasteners via the Loë and Silness plate index (which is an index adapted to patients not fitted).

结局指标
主要结局
Compare the effectiveness of 3 methods of teaching oral hygiene in terms of controlling biofilm formation: MOP (Modified Orthodnotic Plaque Index) classification
时间窗: 6 months of intervention
The average plaque index at six months after inclusion according to the MOP (Modified Orthodnotic Plaque Index) classification. It is evaluated on macro photography in a standardized manner by a blind examiner of the patient's randomization arm. The values range from 0 to 4 for each tooth, which makes an average score of 0 to 48 for the maxillary arch. 0 is the absence of plaque while 48 is an abundance of plaque on all teeth, the worst situation. The score is expressed in absolute value without unit.
次要结局
- Compare the effectiveness of three teaching methods in oral hygiene for the control of gum inflammation: gingival index at six months after inclusion according to the Loë and Silness scale(6 months after bonding the device.)
- Compare the effectiveness of three methods of teaching oral hygiene over time: MOP classification plate index(at 4½ months after installation of the device)
- Compare the effectiveness of three methods of teaching oral hygiene over time: gingival index according to the Loë and Silness scale(at 4½ months after installation of the device)
