title: [Decision to extract for periodontal reasons].
abstract: The decisions to extract that are discussed here mainly relate to severe periodontal bone losses and plain interradicular attacks. Extractions for periodontal reasons appear at several treatment stages: immediate extraction in terminal stages, e.g. for teeth without any strategic importance, or deferred extraction if one chooses to wait for treatment response. The elements of the decision are various: function and strategic importance of the tooth, extension of the lesion, level of the interradicular attack, any endoperiodontal lesions, fractures and luxations, radicular proximity, implication of wisdom teeth, evolution after treatment. All these factors are discussed.
