How long do multirooted teeth with furcation involvement survive with treatment?

Abstract

90% after 5-9 years. The corresponding values for the different surgical procedures were: surgical therapy, 43.1-96% (observation period, 5-53 years); tunnelling procedures, 42.9-92.9% (observation period, 5-8 years); surgical resective procedures including amputation(s) and hemisections, 62-100% (observation period, 5-13 years); and GTR, 83.3-100% (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 nonsurgical mechanical debridement. Vertical root fractures and endodontic failures were the most frequent complications observed following resective procedures. © EBD 2010.
