Background: There are some studies about comparing bone

 replacement grafts.The aim of this study is clinical evaluation of effect of

 Osteon®(as a new bone material)& Bio-Oss® (Bovine-derived hydroxyapatite) in

 the treatment of mandibular molar class II furcation defects in humans.

 Method and Materials: 11 patients ( 10 females and 1 male ,age range

 27 to 59 years mean age 45.5±11.8 years ) who had at least 22 mandibular class

 II buccal or lingual furcation defects were treated either with Osteon ( as case

 group) or Bio-Oss (as control group) .Each defect was randomly assigned to

 either case group or control group. Clinical parameters and the soft tissue and

 hard tissue measurements including Plaque Index (PI), Gingival Index(GI),

 Gingival Recession of furcation area (GR), Pocket depth (PD),Clinical

 attachment level (CAL),Horizontal defect depth (HDD),Vertical defect depth

 (VDD)were recorded at base line and six months after surgery. Date

 were analysed usingT-Tests or Wilcoxon.

 Results:Similar healing results were observed for both treatments.Yhe

 results showed significantly probing depth reduction( Case group:0.77mm &

 control group: 0.84mm) and HDD reduction (Case group: 0.51 mm & control

  2group: 0.8mm) and PI reduction.There was not statistically significant difference

 between groups in all soft and hard tissue parameters.

 Conclusion: The findings of this study showed that the effect of using

 Osteon as a bone graft material is the same of Bio-Oss in the treatment of

 mandibular class II furcation defects .
