[Bio-Oss collagen bone grafting in the treatment of endodontic-periodontic lesion].

OBJECTIVE

To study the effect of Bio-Oss collagen for bone grafting in the treatment of endodontic-periodontic lesion.

METHODS

Thirty patients (37 teeth) with endodontic-periodontic lesions received root canal therapy and periodontal treatment. Four weeks after the treatment, Bio-Oss collagen was grafted in these teeth. Clinical examinations were performed 1, 3, 6, 9, and 12 months after the surgery.

RESULTS

The mobility of these teeth improved 1 month after the surgery. At 3, 6, 9, and 12 months after the surgery, the pocket depth reduced obviously good attachment and further improvement of the tooth mobility.

CONCLUSION

Bio-Oss collagen for bone grafting can achieve good therapeutic effect for endodontic-periodontic lesions.
