Abstract Objective: To systematically review the survival rate and incidence of complications of furcation‐involved multirooted teeth following periodontal therapy after at least 5 years. Material and methods: Electronic and manual searches were performed up to and including January 2008. Publication selection, data extraction and validity assessment were performed independently by three reviewers. Results: Twenty‐two publications met the inclusion criteria. Because of the heterogeneity of the data, a meta‐analysis could not be performed. The survival rate of molars treated non‐surgically was >90% after 5–9 years. The corresponding values for the different surgical procedures were: Surgical therapy: 43.1% to 96%, observation period: 5–53 years. Tunnelling procedures: 42.9% to 92.9%, observation period: 5–8 years. Surgical resective procedures including amputation(s) and hemisections: 62% to 100%, observation period: 5–13 years. Guided tissue regeneration (GTR): 83.3% to 100%, observation period: 5–12 years. The most frequent complications included caries in the furcation area after tunnelling procedures and root fractures after root‐resective procedures. Conclusions: Good long‐term survival rates (up to 100%) of multirooted teeth with furcation involvement were obtained following various therapeutic approaches. Initial furcation involvement (Degree I) could be successfully managed by non‐surgical mechanical debridement. Vertical root fractures and endodontic failures were the most frequent complications observed following resective procedures.
