Medical grade calcium sulfate hemihydrate versus expanded polytetrafluoroethylene in the treatment of mandibular class II furcations.

Background: Guided tissue regeneration (GTR) techniques have been reported to enhance bone regeneration of molar furcation defects. The current trends in therapy encourage the use of a bioabsorbable barrier. The efficacy of the bioabsorbable barrier needs to be equal to, if not better than, the non-absorbable barrier.
