Effects of fibrin adhesive material (Tissucol) application on furcation defects in dogs.

Abstract

A histological study was conducted to evaluate the effects of fibrin adhesive material (FAM) application on periodontal healing in seven experimental dogs. Bilateral class III furcation defects were surgically created at the second and third premolars, then orthodontic wires were placed around the teeth to induce periodontitis. Six weeks later, the wires were removed and the defects were treated by either surgery alone or surgery plus FAM application. A total of 21 specimens were obtained for histological and histometrical analysis on days 7, 21 and 42. The Mann-Whitney U test showed significantly more new attachment and bone regeneration in the FAM-treated group compared to the control (p less than 0.05). Surgery plus FAM application in the treatment of class III furcation defects seemed to be effective in promoting connective tissue attachment and bone regeneration.
