title: [Reciprocal relationships between orthodontics and periodontics: relevance of a synergistic action].
abstract: The aim of this article is to review evidence on the reciprocal relationships between orthodontics and periodontics. Normal intra-arch and inter-arch relationships have long been considered as an anatomic prerequisite for the preservation of dental health and function. Certain malocclusion traits are associated with difficulties in maintaining good oral hygiene and as a consequence to poor periodontal condition. Therefore, proper alignment of the teeth provided by orthodontic treatment may promote good control of soft deposit and calculus and subsequent periodontal inflammation. The tendency of orthodontic appliances, particularly the brackets and bands to promote the accumulation of plaque and thus increasing the risk of developing localized periodontal disease must however be constantly emphasized. Periodontitis involves progressive loss of the alveolar bone around the teeth, pathological tooth migration and gingival recession with pathological tooth migration and gingival recession as a possible outcome. The effectiveness of orthodontics in conjunction with periodontics in the management of these esthetic and functional defects is highlighted in this review.
