Comparison of the Effectiveness of Three Teaching Methods in Oral Hygiene in Adolescent Orthodontic Patients

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.
