ABSTRACT

The evaluation of the efficiency of guided tissue regeneration in covering the denuded root surfaces has become an important field of study in periodontology. However, the use of non-resorbable barrier membranes can not be used routinely since they need secondary surgical operations. The aim of this study is to evaluate the efficacy of Tutotoplast duramater ® (Pfrimmer-Viggo, Biodynamics, Inc. Germany) membrane in covering of denuded root surfaces and to compare the results of clinical measurements obtained before the surgery and after six months. For this purpose; 20 teeth which have Miller class 1 and 2 defect were included in this study. Initial clinical measurements were plaque index, gingival index, interproximal sulcus depth, interdental papillae width, probing pocket depth, gingival recession depth and width, keratinized tissue width and clinical attachment level. These measurements were repeated at 3rd and 6th months. Initial measurements showed an average of 3.650 mm gingival recession. Following the application of the membrane, the mean root coverage was measured 2.850 mm and at the end of the 6th month, 78% coverage was attained. The clinical attachment level was increased by 3.550 mm and the mean of keratinized tissue width was measured 1.200 mm. The results were found statistically significant when compared with the initial measurements (p<0.05). Additionally, smoking, recession width, papillae width, tooth localization were not found to be correlated with the root coverage. The results of this study showed that the guided tissue regeneration would be considered as a successful method to cover the denuded root surfaces. Furthermore, the results of the collagen membrane which was used in our study to cover the denuded root surfaces can be evaluated that collagen membranes may be as successful as non-resorbable membranes.
