Class II furcation defects (5 mm in height \u00d7 2 mm in depth) were surgically created and immediately treated. Teeth were randomly divided into three groups: group C (control), in which the defect was filled with blood clot; group AB, in which the defect was filled with AB graft; and group AB\/CS, in which the defect was filled with AB graft and covered by a CS barrier. Flaps were repositioned to cover all defects. The animals were euthanized 90 days post\u2010surgery. Mesio\u2010distal serial sections were obtained and stained with either hematoxylin and eosin or Masson's trichrome. Histometric, using image\u2010analysis software, and histologic analyses were performed. Linear and area measurements of periodontal healing were evaluated and calculated as a percentage of the original defect. Percentage data were transformed into arccosine for statistical analysis (analysis of variance; <jats:italic>P<\/jats:italic> &lt;0.05).<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Periodontal regeneration in the three groups was similar.
