Abstract
There are various treatment methods including barrier membranes in attaining periodontal regeneration and regaining the function of destructed periodontal tissues due to periodontal disease.Barrier membranes consist of non-Resorbable and resorbable types such as Dura mater and Guidor® used in the treatment of intrabony defects and classII furcation defects have been shown to be effectively increased the amount of new bone and cementum.In our study we used premolars with class III furcation defects created by removing the bone 4mm apically from CEJ in adult dogs and placed resorbable membrane Dura mater and Guidor® for the test group and flap operation was carried out for the control groups. The effect of membrane on junctional epithelium, alveloar bone, cementum, and gingival connective tisssue in the regeneration and healing potential of periodontal tissues was evaluated and healing results were evaluated histologically and histometrically 8 weeks following the surgical procedure. In the clinical observation, there was no exposure of furcation defects in the control group, whereas slight membrane exposure was noted in the test group. New bone was formed up to the level of the notch in the control group, whereas in the test group new bone formation was observed above the level of the notch. New cementum was formed in both groups of the experiment. The connective tissue observed between the new cementum and new bone in the test group were functionally orientated, compared to the irregular formation of connective tissues found in the control group. Root resorption or ankylosis was not observed in any of the groups. The mean and median of the control group were 4.31% and 2.23% and for the Dura mater group were 27.85% and 15.57% respectively. There was no significant difference between Dura mater and the control group. The mean and median of the control group were 4.31% and 2.23% and for the Guidor® group were 37.27% and 37.19% respectively. There was a significant difference in these two groups(P<0.05). The mean and median of the Dura mater group were 27.85% and 15.57% and for the Guidor® were 37.27% and 37.19%. There was no significant difference between the two test groups. Thus, by using Dura mater and Guidor in classIII furcation defects, the predictable amount of periodontal ligament and alveolar bone regeneration may result.
