Abstract:
OBJECTIVETo evaluate the potential role of BME-10X collagen/hydroxyapatite (HA) bone graft in periodontal tissue regeneration.
METHODSFour 18 months old male beagles in the experiment were treated with non-surgical periodontal therapy. At the sites of mandibular 3rd and 4th premolars at the time of dogs were treated with non-surgical periodontal therapy one week later, the teeth with the same name in the same jaw were selected to the experimental group (T group) or the control group (C group) at random. The defects in T group were filled with BME-10X collagen/HA bone graft while the defects in C group were filled with nothing. The dogs were sacrificed in twelve weeks and analyzed by histopathology.
RESULTSThe defects in T group got more tissue regeneration compared with the defects in C group. The height of new bone (NB) was (3.01 +/- 0.14) mm in T group versus (1.32 +/- 0.11) mm in C group (P < 0.05). The height of new periodontal ligament (NP) was (3.12 +/- 0.19) mm in T group versus (1.35 +/- 0.12) mm in C group (P < 0.05). The height of new cementum (NC) was (3.30 +/- 0.15) mm in T group versus (2.70 +/- 0.12) mm in C group (P > 0.05). The new tissue guided by the bone graft was the same as the normal tissue in histopathology analysis.
CONCLUSIONThe results of the study suggest that BME-10X collagen/HA bone graft is a good bone graft for periodontal tissue regeneration.
