title: [The application of frozen homogenic brephobone in surgical treatment of chronic periapical periodontitis]
abstract: Clinical effectiveness of frozen homogenic brephobone as a filling material in the treatment in the treatment of chronic periapical periodontitis was evaluated.42 patents with chronic periapical periodontitis,periapical,cyst and periapical granuloma were observed.After apical curettage was performed,22 cases were filled with frozen homogenic brephobone and other cases were close bone cavity with traditional treatment.All these cases were then covered with periodontal packing agent.Radiograph and clinical observation were made respectively at 2 week,1 month,3 month,6 month and 12 month recall visit following the surgery.It was found that the way of filling with frozen homogenic brephobone is more advantageous than the traditional way.
